Michigan team develops battery tech to enable 5x faster EV charging in the cold
The breakthrough from the University of Michigan could fundamentally improve winter usability for electric vehicles, enabling lithium-ion batteries to charge up to 500% faster in subfreezing conditions. The advance, which involves a dual approach of microchannel architecture and a stabilising electrode coating, promises fast charging without compromising range. The team’s method relies on precision-drilled microscale channels in the graphite anode—roughly 40 microns wide—paired with a 20-nanometre-thick glassy coating made of lithium borate-carbonate. This combination prevents the formation of lithium plating, a performance-hindering phenomenon where lithium metal accumulates on the electrode surface during charging. Test cells incorporating both modifications retained 97% of their capacity after 100 fast-charge cycles at –10°C. Critically, they reached this performance without redesigning the fundamental cell chemistry or sacrificing energy density, meaning they could be integrated into existing manufacturing lines. “For the first time, we’ve shown a pathway to simultaneously achieve extreme fast charging at low temperatures, without sacrificing the energy density of the lithium-ion battery,” said Neil Dasgupta, associate professor of mechanical engineering and materials science at the University of Michigan. Cold-weather charging has long plagued EV performance, with ion mobility through the electrolyte slowing significantly in low temperatures. Current strategies to mitigate this issue often involve external thermal management or design compromises that reduce overall energy density. The University of Michigan’s solution addresses the challenge internally—improving ion accessibility and stability at the microstructural level. The university has filed for patent protection, and Arbor Battery Innovations—co-founded by Dasgupta—has licensed the microchannel technology for commercialisation. umich.edu
Scientists build photovoltaic-thermal panel hosting four different cooling techs – pv magazine International
Researchers from the Middle East have simulated a novel PV thermal module which includes a thermoelectric generator above the absorber layer, conical helical tape in the cooling tube and a ferrofluid. These technologies reportedly contributed to increased PV efficiency and thermal efficiency by 2.12% and 23.34%, respectively. May 20, 2025 Lior Kahana Scientists from Saudi Arabia and Iraq have proposed a novel PV thermal (PVT) module that integrates several techniques for cooling. Namely, the novel method uses a thermoelectric generator (TEG), conical helical tape in the cooling tube, and a ferrofluid controlled by a magnetic field. The module was numerically simulated using the Ansys Fluent software. TEGs can convert heat into electricity through the “Seebeck effect,” which occurs when a temperature difference between two different semiconductors produces a voltage difference between two substances. The devices are commonly used for industrial applications to convert excess heat into electricity. However, their high costs and limited performance have thus far limited their adoption on a broader scale. Unlike the conventional use of TEG modules with PV, which are placed on the rear of the panel, this research proposs to put them above the absorber layer. The cooling tube, placed on the rear of the PVT module, is equipped with a conical tape to increase jet impingement. It is a field with a mixture of water (H2O) and magnetite (Fe3O4), for both its heat transfer and magnetic responsiveness. “The novelty of the present study lies in the comprehensive combination of multiple innovative performances, each addressing specific aspects of PV module optimization,” said the researchers. “This multidimensional approach distinguishes our study from existing literature, filling gaps in the current understanding of advanced PV technologies.” The research team used magnetohydrodynamic (MHD) to control the movement of ferrofluid within the tube, adding an extra layer of optimization. The Hartmann number (Ha), which defines the ratio of electromagnetic force to the viscous force, was used as a dimensionless factor representing the magnetic force in the y-direction, which the scientists said plays a key role in evaluating the impact of magnetic forces on the unit. The conical tapeImage: Northern Border University, Case Studies in Thermal Engineering, CC BY 4.0 The simulations showed that the values of photovoltaic efficiency, TEG efficiency, and thermal efficiency increased by approximately 2.12%, 74.29%, and 23.34%, respectively, with the rise of inlet velocity. However, an increase in Ha leads to a decline in PV panel temperature and an augment in the uniformity of PV panel temperature by about 5.56%. “As inlet velocity is elevated, the intensified interaction of the nanofluid with the upper wall leads to a reduction in the panel temperature, enhancing the contour uniformity by approximately 51.2% and 58.19% for Ha values of 0 and 90, respectively,” the researchers stressed. “Conversely, with an increase in Ha at inlet velocity = 0.09, the uniformity of photovoltaic panel temperature experiences a reduction of about 5.56%.” The analysis also showed an increase in dust dissipation decreases the PV efficiency by 26.93%, TEG efficiency by 17.45% and thermal efficiency by 9.78%. “Moreover, with an increase in Ha, the values of TEG efficiency and thermal efficiency show a decrease of about 8.21% and 2.91% in the absence of dust. The decrement of the boundary layer thickness with the augmentation of inlet velocity contributes to an improvement in the cooling rate,” added the team. The scientists also found that the combination of the four different cooling techniques presents a paradigm shift in the quest for optimizing PV module performance. “In upcoming research, the application of a spectral filter of ferrofluid could be explored further. Additionally, employing porous media to augment the cooling rate within the tube zone presents another avenue for investigation,” they concluded. The new PVT panel design was described in “Improving PVT Module Efficiency with Helical Tape and Magnetic Cooling Under Dust Deposition,” published in Case Studies in Thermal Engineering. Researchers from Saudi Arabia’s Northern Border University, University of Ha’il, Princess Nourah bint Abdulrahman University, King Abdulaziz University, Prince Sattam bin Abdul-Aziz University, and Iraq’s Warith Al-Anbiyaa University and Al Safwa University College contributed to the study.

Wärtsilä's VP of Energy Storage & Optimization Andy Tang Discusses the Tivo-ing of Electricity In the ever-evolving landscape of energy management, the conversation is shifting from mere consumption to smart optimization. Leading this charge is Andy Tang, the Vice President of Energy Storage & Optimization at Wärtsilä. With the increasing demand for sustainable energy solutions, Tang's insights are pivotal in reimagining how electricity is produced, stored, and used. The Vision of “Tivo-ing” Electricity The concept of "Tivo-ing" electricity is a metaphor drawn from the way TiVo revolutionized television viewing. Just as TiVo allows users to record, pause, and skip through content at their convenience, Tang envisions a future where consumers can manage their energy use more effectively. This idea emphasizes the importance of flexibility and control in energy consumption—a necessity as we transition to more decentralized energy systems. Energy Storage: The Backbone of Flexibility Andy Tang highlights the critical role of energy storage in achieving this vision. Modern energy systems face challenges such as intermittent renewable energy generation and variable demand. By utilizing advanced energy storage solutions, consumers can store excess energy during peak production times (e.g., sunny or windy days) and draw from that reserve during high-demand periods. This not only optimizes energy usage but also stabilizes the grid, making it more resilient to fluctuations. Optimization Strategies Wärtsilä is at the forefront of developing sophisticated algorithms and technologies that optimize energy storage systems. According to Tang, effective energy management involves understanding patterns in energy consumption and generation. Through data analytics and machine learning, Wärtsilä can help both residential and commercial customers predict their energy needs, thereby enabling better decision-making regarding when to store or draw energy. Some key strategies mentioned include: Predictive Analysis: Utilizing historical data and AI to forecast energy demand and production. Diversified Energy Sources: Encouraging the integration of various renewable sources to provide a more stable energy supply. Smart Grid Technologies: Implementing solutions that allow real-time communication between energy producers and consumers. The Benefits for Consumers and the Environment The benefits of implementing such optimization strategies extend beyond individual savings. By efficiently managing energy use, consumers can reduce their carbon footprint while also benefiting from lower electricity bills. As more individuals and businesses adopt these technologies, the cumulative effect can lead to significant reductions in greenhouse gas emissions. Future Outlook As we look to the future, Tang expresses optimism about the potential for innovation in the energy sector. The ongoing advancements in battery technology, AI, and data analytics are paving the way for more intelligent energy systems that can adapt to changing conditions. This evolution is crucial as cities around the world strive for energy independence and sustainability. With the world increasingly aware of the impacts of climate change, the "Tivo-ing" of electricity offers not just a visionary approach to energy management but also a practical pathway toward a more sustainable future. Andy Tang’s leadership in this initiative positions Wärtsilä as a key player in driving forward this essential revolution in the energy sector. In conclusion, as we stand on the cusp of a new era in energy consumption, the contributions of thought leaders like Andy Tang will be instrumental in shaping a more efficient and environmentally friendly energy landscape. The journey of Tivo-ing electricity is just beginning, and its implications could redefine how we think about, use, and optimize energy in the years to come.
We Don’t Need Base Load Power
Last Updated on: 10th November 2023, 06:40 pm Rick Perry, the former Governor of Texas and former Secretary of the Department of Energy, told Fox News in an interview that we need base load power. He believes we need base load power because it is what we use when we turn a light on at 2:00 in the morning. He’s wrong. But unfortunately, a lot of people understand things the way he does, and they are holding the energy transition back. Base load power may supply the electricity in the middle of the night in many cases, but power from other sources could be used instead. The issue is not technical. It is just a matter of cost. If something came along that could provide that electricity cheaper and better, we could use it instead and save money. (Spoiler: something has.) We should think about what the base load is and why it matters. Back in the early days of the electric grid, power providers came to understand that there would be a minimum demand level that they could count on always being there. Demand would never fall below that level, as long as the grid was operating normally. That minimum demand level is the base load. Please note that the base load is the minimum demand level. A base load power plant is designed specifically to provide for the minimum demand. Because the base load would always be there, the plant could run at 100% power, 24/7. The plant never would need to adjust to changes in demand, so it could be built without the features necessary to follow changes in demand. And that made construction and operation of the plant very inexpensive. Obviously, since base load plants cannot adjust for changes in demand, there have to be other power plants that perform that job. They include load-following plants, along with some other types. They supply all of the electricity we use in excess of the minimum. The problem we have with them is that the electricity they generate costs a lot more than base load power. Perhaps we should make note of a few things here. The big trick to running an electricity grid is to make sure that power production meets demand as closely as possible. The load-following power plants could provide 100% of our electricity, if we were willing to pay the price. In fact really small electric grids generally don’t have any base load power. In diesel-powered grids on islands, the diesel generators automatically meet demand, in their clunky manner. One big problem they have is that the electricity they generate is really expensive. Since demand is always changing, base load power plants cannot supply 100% of grid power over any extended period of time. For example, the only way a grid could be powered entirely by base load power for a full hour would be if the demand remained at the minimum level, unchanged, for that hour, a scenario that is extremely unlikely. Base load plants cannot supply all our power. So, the reason we use base load power plants is not that they are required technically, but because we have wanted them to keep costs down. We do not need them to provide our electricity at 2:00 AM. We have wanted them to provide a fixed amount of cheap electricity, throughout the day, and that fixed amount would be the minimum we would ever need. We can view base load power technology as a paradigm for a power grid, but it is just one paradigm where others could be used. And in fact, there is no reason to adhere to the base load paradigm if another comes along that is less expensive. Recently, NextEra Energy issued its Investor Conference Report 2022 to its stockholders. In it, NextEra Energy claims to be the largest provider of renewable energy in the United States. But it also owns, directly and through subsidiaries, a lot of fossil fuel plants and seven nuclear reactors. Interestingly, as it looks to the future, NextEra seems not to be particularly interested in thermal power plants, the type that includes base load plants. It is planning to close its last coal-burning plant in 2028. And it expects electricity generated by natural gas to decline to 18% overall for all US producers by 2035. A look at a graphic on page 122 shows us why. There are some terms used for the chart that require explanations. “Near-firm” power assumes a battery that will have reliability during peak hours that is roughly the equivalent of dispatchable generation sources. The “storage adder” is the increase in cost of an energy source that is needed to cover the cost of storage. We should mention for interest sake that the “carbon adder” is the increase in cost of fossil energy due to governmental policies. One thing to consider is that while neither near-firm solar nor near-firm wind power would get us through every night reliably by itself, based on the definition for near-firm, a combination of the two could be designed to do that easily for most places, most of the time. This is because solar and wind power are generally complimentary; wind power is strongest at night and in the winter, and solar is only productive during the daytime and generally most productive during the summer. And if there is insufficient power from those two sources, there are other renewable energy sources available, including hydro-power, tidal power, biomass, geothermal, and others. And long-range transmission lines can bring power in from other parts of the country. NextEra’s chart shows that of the eight electricity sources listed, the least costly are near-firm wind and solar. The others are all more expensive, and with the exception of offshore wind power, they happen to be base load sources. We might note that existing natural gas, nuclear, and coal plants have limited life expectancy and are due to be replaced at some point. And we should also note that the electricity
MIT startup claims a breakthrough for 'holy grail' of batteries, doubles energy density
As always, a healthy dose of skepticism is important when it comes to an alleged “battery breakthrough”. Those announcements are being made every 2-3 months over the last decade and rarely anything comes to it, but at least we can always rely on the 5-8% annual incremental improvements in li-ion battery capacity. It’s not a “breakthrough” or doubling of capacity, but it adds up. Now it’s time for another MIT spinout, after the defunct A123 Systems, to claim to have created the next battery breakthrough with an anode-free li-metal battery that could achieve an energy density of up to 500 Wh/kg – about twice the capacity of the current cells found in Tesla’s vehicles for example. The claims come from SolidEnergy, a company created in 2012 by MIT alumnus and former postdoc Qichao Hu ’07. Advertisement - scroll for more content Hu explained his concept to the MIT News Office: The battery essentially swaps out a common battery anode material, graphite, for very thin, high-energy lithium-metal foil, which can hold more ions — and, therefore, provide more energy capacity. Chemical modifications to the electrolyte also make the typically short-lived and volatile lithium metal batteries rechargeable and safer to use. Moreover, the batteries are made using existing lithium ion manufacturing equipment, which makes them scalable. After first unveiling a working prototype in October 2015, SolidEnergy raised over $12 million from investors and now plans to start production for some projects with drones, which could really use the higher energy density, and they hope their battery will start making its way into consumer electronics next year. By 2018, Hu sees his battery in electric cars: “Industry standard is that electric vehicles need to go at least 200 miles on a single charge. We can make the battery half the size and half the weight, and it will travel the same distance, or we can make it the same size and same weight, and now it will go 400 miles on a single charge.” The scientist described his energy density breakthrough as “kind of the holy grail for batteries”. The main issue with li-metal batteries is that they react poorly with the battery’s electrolyte and become unstable, which reduces the durability of the battery. Hu says that he solved the problem by developing a solid and liquid hybrid electrolyte solution: “He coated the lithium metal foil with a thin solid electrolyte that doesn’t need to be heated to function. He also created a novel quasi-ionic liquid electrolyte that isn’t flammable, and has additional chemical modifications to the separator and cell design to stop it from negatively reacting with the lithium metal.” The company didn’t release many details about the battery, but it claims that it now has “safety and longevity features of lithium ion batteries”, while having about twice the energy density. It could be interesting, but we haven’t heard much about cost either. Hu says that the system is scalable, but without proving a cost per kWh figure. FTC: We use income earning auto affiliate links.

The automaker plans to enhance existing collaborations and invest in research and development to improve battery technology and production efficiency. This strategy indicates VW's intent to stay competitive without overextending its resources into building autonomous facilities. Addressing Market Concerns Diess's remarks come at a time when the EV market is experiencing turbulence. Supply chain disruptions and rising material costs have led several manufacturers to reassess their production strategies. By denying the plans for a giant battery factory, Diess seeks to alleviate stakeholder concerns about overcommitting to a volatile market. Looking Ahead VW is slated to unveil more comprehensive insights into its long-term EV strategy at an upcoming industry summit. Stakeholders will be eager to learn how the company plans to address challenges while maintaining its commitment to sustainable mobility. As the competition in the EV sector intensifies, VW's decisions will remain closely monitored by both investors and consumers alike. In conclusion, while the speculation about a massive battery production facility might have stirred interest, VW remains grounded in its approach, combining partnerships and innovation to forge a robust path in the electric vehicle landscape.
Rio Tinto and Codelco to develop lithium mines in Chile
The agreement will see Rio Tinto acquire a 49.99 per cent stake in Salar de Maricunga SpA, through which Codelco holds its licences and mining concessions on the Maricunga salt flat. It will provide an initial investment of $350m towards studies and resource analysis in order to inform a final investment decision. Once that decision is made, Rio Tinto will put a further $500m towards construction costs – with construction set to go ahead by the end of the 2020s. Additionally, it plans to invest $50m into Salar de Maricunga if the joint venture succeeds in delivering lithium by 2030. The transaction is set to close by the end of Q1, 2026. The venture will also support local infrastructure in surrounding communities, including the development of power supply and roads, as well as “applying leading extraction, processing and reinjection technologies to maximise the recovery of minerals and minimise its environmental footprint.” Rio Tinto CEO Jakob Stausholm said of the agreement: “Codelco is a strategic partner for Rio Tinto in Chile, with this agreement building on our copper joint ventures. We aim to bring significant investment and long-term benefits to the Atacama region as we advance Maricunga and Nuevo Cobre together, with a focus on responsible sustainable development including shared infrastructure and solutions to minimise water usage.” Chile is the world’s second-largest producer of lithium and its government increasingly controls the value chain and access to reserves. Right now, only two private companies are mining lithium there: Chilean firm SQM and the US company Albemarle. President Gabriel Boric has called lithium “the best opportunity we have for the transition to a sustainable and developed economy”, and wants lithium contracts to only be awarded as public-private partnerships subject to state control. With SQM’s current contract set to expire in 2030 and Albemarle’s in 2043, Boric has said the government will not terminate these but hopes that the companies will be open to state participation before they expire. It’s in this context that Codelco has entered the lithium mining industry. Through it, the government plans to collaborate not only with Albemarle and SQM but other potential mining companies. For example, SQM and Codelco recently reached an initial agreement for a joint project in the Atacama Desert where the state holds a majority stake – which is now also the case with the Rio Tinto deal. This is against the backdrop of a number of other failed initiatives to create value from Chile’s lithium resources. Earlier this month, Chinese EV maker and the metals group Tsingshan both pulled out of plans to build production facilities for LFP cathode material in Chile, despite a preferential agreement with the Chilean government for the purchase of lithium. The companies cited the falling global prices of lithium as a reason for abandoning their projects. businesswire.com

We Can Have (Just About) Everything We Want For Energy & The Climate
The only things we have to give up are killing people and wrecking the environment. Okay, let’s start with a list of the things we would really like to have for energy and the climate in the year 2050. For many CleanTechnica readers, the list of things we want to replace the business-as-usual (BAU) approach might look a bit like this: A grid that is stable 100% of the time Saving all of the 5.3 million lives that would be lost globally, every year, if we fail to stop air pollution Eliminating the 57 billion tonnes of CO₂e that would be emitted each year under BAU Reducing all-purpose end-use energy requirements by over 50% Reducing annual worldwide energy costs by over 60% Reducing annual energy, health, and climate costs by over 90% Using less than 0.6% of our land to provide for energy (a lot less than under BAU) Creating 28 million more long-term, full-time jobs than are lost in the transition Eliminating energy sources that are too costly, lead to insecurity, or are possibly dangerous Covering all of the cost of accomplishing these things from energy sales (which, remember, are lower than with BAU) There are a couple of things we would have to give up to get to that future. They are: This list was not made up on a whim. Slightly modified for brevity, it is from a study that was released in June, “Low-cost solutions to global warming, air pollution, and energy insecurity for 145 countries,” (LCS) by Mark Z. Jacobson, et al. The study says the list is realistically achievable. We just have to do it. One possible timeline for change. Note that lighter areas on top represent energy use being eliminated from the BAU approach, and the colored areas represent wind, water, and solar energy. The image is from the LCS study. Though we understand that a lot of damage has already been done by the use of fossil fuels, the study tells us that we may actually be able to move into a period of relative prosperity with better living conditions both for us humans and for all other creatures. It is true that fossil fuel jobs will be lost as we transition to 100% renewable energy. And it is true that there will be stranded assets. The same is true of nuclear power. But these industries have never made any claim to be sustainable. And it is simply a fact (or more accurately, a tautology) that if something is not sustainable, its condition is terminal. One way or the other, people invested in these areas might be better off if they get ready to move on to something else soon. Also, we should recognize that the BAU scenario would very possibly leave us with inescapable destruction for much of the planet, with millions of people dying every year. So, the choice is (1) good air, good health, lots of new jobs paying good money, great energy savings leading to lower costs overall, eliminating polluting emissions so we can save the environment and our grandchildren can enjoy life in a lovely world, or (2) doom, despair, and death. We can take our pick. Mark Z. Jacobson is well known to many CleanTechnica regulars. This site was where I first learned about him, over ten years ago. Since that time, a large number of articles have appeared here about things he has done or said. Jacobson seems to have been working on reexamining one particular thesis for all those years, as times change. The message is that we will really gain in nearly all possible ways, if we just quit using dangerous, destructive, and over-costly power sources. But as the times change, Jacobson’s message must be updated to stay accurate. It looks like an unending job. Climate change has turned into the climate crisis, making everything more urgent. We have increased risks to human health. There is the increasing specter of wars leading to energy insecurity, with the one in Ukraine possibly intentionally causing insecurity to take advantage of it. Our food supplies are increasingly threatened. Droughts and floods … I could go on and on, but I have to stop somewhere, or this article will never get done. Last February, CleanTechnica’s Steve Hanley wrote an article I suggest reading, “Renewable Energy: Zero Blackouts, Millions Of New Jobs – Mark Z. Jacobson.” It goes over details of what Jacobson is doing. The present article really just expands on that one. I will reiterate from Steve Hanley’s article a point that Jacobson stresses: We can get all the energy we need, very inexpensively and very reliably, if we concentrate on wind, water, and solar (WWS) as the sources. Please note, hydrogen and geothermal energy are included in the WWS sources, but bio-fuels and nuclear energy are not. The reason for the new article in June is that things are constantly changing, and this means that the statement has to be revisited once more. It is an ongoing job for Jacobson and his staff, as general conditions change and new technology is increasingly adopted. So the latest study addresses several new things. The first new material appears because the area under study is changing. There are 145 countries in the LCS study, an increase of two from the earlier studies. That might not seem like much difference, but there are other new approaches relating to the areas under study. The countries are grouped for grid stability analysis into 24 regions. One observation about these regions is the way they are chosen. Dividing the world into regions sounds like a simple matter of cutting up a map into big pieces, and there are some big areas. China, Hong Kong, Mongolia, and North Korea are all in the same region. But some areas are carefully made separate from everything else. Each of the countries Cuba, Iceland, Israel, Jamaica, Mauritius, and Taiwan constitutes a region by itself. Another update has to do with raw end-use energy
Electric vehicle battery cost dropped 80% in 6 years down to $227/kWh - Tesla claims to be below $190/kWh
Profitable production of electric vehicles is highly important. Our capitalist society revolves around profitability and therefore, if electric vehicles are to prevail over gas-powered cars, they need to be profitable to manufacture in mass. A new study published this month by McKinsey & Company and embedded below looks into how automakers can move past producing EVs as compliance cars and “drive electrified vehicle sales and profitability”. Unsurprisingly, it describes battery economics as an important barrier to profitability and though the research firm sees a path to automakers making a profit selling electric vehicles as battery costs fall, it doesn’t see that happening for “the next two to three product cycles” – or between 2025 and 2030. That’s despite battery costs falling from ~1,000 per kWh in 2010 to ~$227 per kWh in 2016, according to McKinsey. Advertisement - scroll for more content The company wrote in the report: Despite that drop, battery costs continue to make EVs more costly than comparable ICE-powered variants. Current projections put EV battery pack prices below $190/kWh by the end of the decade, and suggest the potential for pack prices to fall below $100/kWh by 2030. We are talking about complete battery pack cost and not just the battery cells. The costs of both are often confused. Automakers capable of staying ahead of that cost trend will be able to achieve higher margins and possible profits on electric vehicle sales sooner. Tesla is among the automakers staying ahead of the trend. While McKinsey projects that battery pack prices will be below $190/kWh by the end of the decade, Tesla claims to be below $190/kWh since early 2016. That’s how the automaker manages to achieve close to 30% gross margin on its flagship electric sedan, the Model S. Though the Model S has a starting price of $68,000 and battery costs need to fall again in order to allow a starting price of $35,000, like for the upcoming Model 3. Tesla aims to reduce the price of its batteries by another 30% ahead of the Model 3 with the new 2170 cells in production at the Gigafactory in Nevada. It should enable a $35,000 price tag for a vehicle with a range of over 200 miles, but McKinsey sees $100/kWh as the target for ” true price parity with ICE vehicles (without incentives)”: Given current system costs and pricing ability within certain segments, companies that offer EVs face the near-term prospect of losing money with each sale. Under a range of scenarios for future battery cost reductions, cars in the C/D segment in the US might not reach true price parity with ICE vehicles (without incentives) until between 2025 and 2030, when battery pack costs fall below $100/kWh, creating financial headwinds for automakers for the next two to three product cycles. It matches the estimates of most battery manufacturers, but of course, Tesla is again pushing for a more aggressive timeline. CEO Elon Musk has previously hinted at a possibility of achieving a battery cost of $100 per kWh in 2020 – 5 to 10 years before most estimates. They plan to achieve the price target with economies of scale and manufacturing efficiency improvements through the Gigafactory program. Whether they can achieve it or not remains to be seen, but it’s not impossible if they are truly currently below $190 while projections didn’t estimate that price point until 2020. It wouldn’t be surprising to see other automakers following Tesla with their own efforts to build giant battery factories in order to reach similar price points. Another explanation for the cost lead could be the type of cell and the pack architecture. Tesla has been mostly alone in producing battery packs for electric vehicles using thousands of individual cylindrical li-ion battery cells in each pack. In contrast, established automakers, like Nissan with the LEAF or even GM with the Chevy Bolt EV, have been using fewer but larger prismatic cells to build their electric vehicle battery packs. Recently, new electric vehicle companies have been following Tesla with cylindrical li-ion battery cells instead of prismatic cells like most automakers.

A critical moment for Brazilian energy storage – pv magazine International
Brazil is at a pivotal juncture in its energy landscape, facing a critical decision that will shape its future energy strategy. The nation must choose between continuing to invest in traditional, costly thermal power plants or embracing modern, flexible, and sustainable solutions like Battery Energy Storage Systems (BESS). This choice is not merely technical but strategic, determining whether Brazil remains anchored in outdated practices or leads the charge in the global energy transition. (pv-magazine.com) Current Energy Landscape As of early 2025, Brazil's energy matrix is undergoing significant transformation. The country has installed approximately 53.9 GW of solar power, accounting for about 21.9% of its electricity generation. This positions Brazil as the sixth-largest nation globally in terms of installed solar capacity. The rapid expansion of solar energy underscores the nation's commitment to renewable sources and its potential to lead in sustainable energy solutions. (en.wikipedia.org) The Role of Energy Storage Integrating energy storage solutions is crucial for enhancing the reliability and efficiency of Brazil's power grid. Energy storage systems, particularly BESS, play a vital role in balancing supply and demand, mitigating the intermittent nature of renewable energy sources like solar and wind. By storing excess energy during peak production times and releasing it during periods of high demand or low generation, BESS can ensure a stable and continuous power supply. This capability is essential for accommodating the growing share of renewables in Brazil's energy mix. (pv-magazine.com) Market Dynamics and Growth Projections The Brazilian energy storage market is poised for substantial growth. Analysts project a compound annual growth rate (CAGR) of 20% to 30% through 2030, driven by declining battery prices and increasing energy costs. The affordability of energy storage solutions is making them an attractive option for consumers seeking energy security and cost savings. For instance, the state of Pará has been identified as particularly suitable for BESS deployment due to its high energy tariffs, presenting significant savings opportunities for consumers.

The country lacks a domestic battery cell manufacturing industry, relying on imports for battery components. This dependency can lead to higher costs and supply chain vulnerabilities. Additionally, regulatory hurdles and the need for substantial investment in infrastructure pose obstacles to widespread adoption. Addressing these challenges requires strategic policy decisions, investment in local manufacturing capabilities, and supportive regulatory frameworks to foster a conducive environment for energy storage technologies. (energynews247.com) Conclusion Brazil stands at a crossroads, with the opportunity to redefine its energy future. By investing in energy storage solutions, the nation can enhance grid reliability, support the integration of renewable energy, and position itself as a leader in sustainable energy. The decision to embrace or delay this transition will significantly impact Brazil's energy landscape in the coming decades.
After production halt in Sweden: Work at Northvolt plant in Germany continues
The recently announced closure of Northvolt’s battery cell production in Skellefteå, Sweden—set to cease by 30 June 2025—has sparked renewed scrutiny over the company’s future projects. Adding to the speculation, the German Der Spiegel reported that one of Northvolt’s German subsidiaries, Northvolt Germany TopCo GmbH, has allegedly initiated restructuring proceedings. “The future of the unfinished plant in Schleswig-Holstein remains uncertain,” the magazine stated. According to the report, the so-called ‘TopCo’ also includes the German project entity Northvolt Drei Project GmbH (formerly Northvolt Germany GmbH), which has received approximately €600 million in German taxpayer funding through a convertible bond. However, in response to an enquiry from electrive, Northvolt clarified that none of its German entities are currently insolvent. The supposed restructuring procedure may refer to a StaRUG process—a preventive restructuring framework introduced in Germany in 2021. The framework allows companies facing imminent financial distress to restructure operations without formal insolvency proceedings, bridging the gap between out-of-court settlements and traditional bankruptcy processes. KfW funds tied exclusively to Heide Northvolt also emphasised that Northvolt Germany TopCo GmbH and Northvolt Drei Project GmbH are separate legal entities. The TopCo oversees all non-project-related operations in Germany and is exclusively financed by its insolvent Swedish parent, Northvolt AB. There is reportedly no operational link to Northvolt Drei Project GmbH, which has access to alternative sources of funding. Still, according to NorthData, the project company is fully owned by Northvolt Drei HoldCo GmbH, which in turn is a wholly owned subsidiary of Northvolt Germany TopCo GmbH—indicating some structural connection remains. The move announced in Sweden is said to have no immediate impact on the Heide project. “Work on the project and on the construction site is continuing,” a Northvolt spokesperson told electrive. “All current measures are being implemented in close coordination with KfW. The focus is particularly on value-enhancing infrastructure work.” The KfW convertible bond funding is project-specific and may only be used for the Heide site. It is not available to cover financial shortfalls or debts of the Swedish parent company, Northvolt AB. The political aftermath in Germany—namely, who approved and disbursed state aid and what information was available at the time—is likely to be addressed in investigative committees at both federal and state levels. The German Federal Audit Office is also reviewing the state funding provided to Northvolt. The outcome remains open. That construction in Heide continues without interruption, with a focus on infrastructure development, may also relate to court-appointed administrator Mikael Kubu’s ongoing efforts to secure a partial sale of the Northvolt group. “The search for a buyer is progressing,” Kubu said on Thursday, noting that negotiations are underway for various company assets—if not for the firm as a whole, then possibly for its Arctic Circle plant or the construction site in Germany. Northvolt’s German spokesperson echoed this optimism to electrive: “Northvolt AB is still in intensive discussions with potential investors—there is significant interest in the Heide location.” Information per e-mail, spiegel.de, northdata.de

Why Should We Pay Extra for Nuclear Power?
There were a couple of interesting developments in June in regards to electric power. One was that NextEra Energy issued its Investor Conference Report 2022 to its stockholders. Another was a paper from Stanford University, “Low-cost solutions to global warming, air pollution, and energy insecurity for 145 countries,” (LCS study) by Mark Z. Jacobson, et al. Looking into them is rather interesting. The first of these makes very clear that in the opinions of the people running NextEra Energy, combustion generating sources and nuclear power are getting too expensive. Furthermore, their opinion is that the most expensive of these, at least in the late 2020s, will be small modular nuclear reactors (SMRs). The above chart, from their investor report, shows this. A couple of things stand out because of their explicit statements in the chart. One is, “Attractive renewables economics are expected to continue driving a transformation of the U.S. generation fleet.” The other says, “We expect further technology improvements and cost declines will extend the competitiveness of onshore renewables and storage. We should make clear, just in case anyone doesn’t know, that NextEra is hardly anti-nuclear. While it is already the biggest investor in renewable energy in the US, it does own seven nuclear reactors, including the one at Seabrook. One thing to make note of in the chart is that the term “near-firm,” applied to wind and solar power. It means that those power sources are backed up by a four-hour battery, which NextEra regards as sufficient to make the renewable power sources roughly equivalent to dispatchable sources during peak hours. Another thing is that the storage adder is seen to raise the costs of solar and wind power by about 0.5¢/kWh. This is represented in the chart by the shaded areas on the bars for solar and wind power. Another thing to note is that in this chart, electricity from new, near-firm solar and wind plants is a good deal less expensive than electricity from existing nuclear plants. Let’s state this clearly: We are paying extra for electricity from nuclear plants, even after they have been paid down, and even though the sun can shine and the wind can blow almost all the time, because of really cheap battery storage. Put another way, it would be cheaper to close the nuclear plants and replace them with new renewable facilities. When we compare near-firm wind and solar in this chart to SMRs, the advantage of renewable energy is even more impressive. NextEra clearly expects SMRs to generate electricity that costs anywhere from three to five times as much as the near-firm renewables. Aside from the fact that it is not possible to do everything all at once, there really is no excuse for this. Near-firm renewables may not be perfect, but we can be certain that SMRs will not be perfect either, and we don’t know what types of failure they will experience. It is true that some SMRs are designed to follow changes in demand, but the changes will take time and that makes them very inferior to near-firm renewables, which can change within less than the time of a single cycle of AC power. We should note that even if SMRs really cannot melt down (a premise we should not accept on its face value) they produce a lot of waste, reportedly much more than existing plants, and that waste is a serious problem. Our conclusion should be that SMRs are very inferior to near-firm renewables in just about every respect. We should turn to the LCS study. As an academic project, it is based on existing data, modeling, and computations. To give an idea of what that means, we might list some of the steps taken for one portion of the study. It breaks the world into 28 regions, and for each region models the weather that can be expected over a three year period starting in 2050. This is done for different scenarios for generating and using electricity. Energy usage for each region is recalculated for intervals of 30 seconds for the entire three years. That is a lot of computing. The LCS study does show an analysis based on business-as-usual. But for the renewables section of the study, it does not examine the use of nuclear energy for several reasons. One is that nuclear power produces waste that will be toxic for the foreseeable future and then some. Another is that it is inherently dangers in multiple ways. But of interest here, nuclear power is not built into the energy mix for renewables partly because it is so expensive that it gets in the way of implementing wind, water, and solar power, slowing down our transition away from fossil fuels. So the bottom line is a question: Why should we pay extra for nuclear energy? This article was originally posted to the website of the New England Coalition on Nuclear Pollution and is in the public domain. The positions of the Governor of Virginia on nuclear power and renewable energy make it relevant for today.
