With battery production taking off, concerns are focussed on environmental sustainability, carbon footprint and labour rights where the raw materials are mined. Benedikt Sobotka, Co-Chair at the Global Battery Alliance and Robin Zeng, CEO at Chinese manufacturer Contemporary Amperex Technology, writing for WEF, describe the concept of the digital âbattery passportâ where compliance with the rules is certified and monitored throughout the life … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes âcongestionâ at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. Thatâs certainly the case in the U.S. now. One answer is âhybridisationâ where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
EUâs 40% domestic Cleantech ambition: same target for Wind (easy) and Solar (hard) doesnât make sense
The proposed Net Zero Industry Act includes a target for the EU to manufacture domestically at least 40% of its cleantech deployment needs by 2030. That includes the key technologies of solar PV panels, wind turbines (onshore and offshore), EV batteries, heat pumps and hydrogen electrolysers. But it doesnât make sense to have the same 40% target for all, explain Giovanni Sgaravatti, Simone Tagliapietra and Cecilia Trasi at Bruegel. The main … [Read more...]
How will China respond to the EUâs â40% made at homeâ clean energy tech ambition
The EUâs Net Zero Industry Act wants to drive home-grown production of eight âstrategicâ net-zero technologies, including solar, wind, batteries and CCS. The target is 40% made at home, though the policy is yet to be worked out. You Xiaoying writing for China Dialogue talks to experts in China and the EU for their predictions. Most say that Chinese firms are not very worried. Firstly, they can â and are already making moves to â set up production … [Read more...]
âFlow Batteriesâ for grid-scale storage: modelling cheaper alternatives to Vanadium
Flow batteries are a promising new technology for grid storage. Rather than the standard batteries that store charge in a solid material, they use a solution to store that charge, making large-scale long-duration electricity storage much easier. Vanadium electrolytes have been the preferred choice so far, but affordable supplies are limited and a cheaper alternative will be needed for global scale-up, explains Nancy Stauffer at MIT who describes … [Read more...]
IEA report: global manufacturing capacity is expanding rapidly for solar, wind, batteries, electrolysers, heat pumps
The IEA summarises its special briefing, âThe State of Clean Technology Manufacturing.â Itâs a global update on recent progress in key regions, focussing on five technologies â solar PV, wind, batteries, electrolysers and heat pumps â critical to the energy transition. It should be read to keep decision makers informed of investment trends and the impact of industrial strategies. Overall, manufacturing capacity for these technologies is expanding … [Read more...]
Community Batteries: when theyâre the best option for overcoming grid constraints. And when theyâre not
Community batteries are a shared asset in neighbourhoods with rooftop solar, avoiding the need for every household to have its own battery. Even people unable to have rooftop solar can use it. Itâs taking off in Australia, supported at both the state and federal level. But Bjorn Sturmberg, Alice Wendy Russell, Hedda Ransan-Cooper, Louise Bardwell and Marnie Shaw at the Australian National University summarise their research which warns that it … [Read more...]
How can Europe stop U.S. and China dominance of cars and batteries without being protectionist?
European and Chinese car and battery makers are making plans to set up plants in the U.S. to take advantage of their big new âmade in the USAâ subsidies. They can then ship their vehicles to Europe to sell into its very large and generously subsidised company car market. This puts electric vehicle production in Europe at a serious disadvantage. As William Todts at T&E explains, the EU must respond, instead of effectively assisting the U.S. … [Read more...]
Can Phytomining deliver Critical Minerals at scale: farming plants that accumulate high metal concentrations
Both Europe and the U.S. are making plans to secure supplies of critical minerals as the transition gains pace. Domestic mining or securing import deals with close allies is the main focus. Here, Maria Krol-Sinclair and Thomas Hale at CSIS review the prospects for a new method that will require neither: phytomining. Some plants, called hyperaccumulators, soak up high concentrations of metals into their leaves, bark, and roots. These plants can … [Read more...]
LIBRA: modelling sustainable Battery supply chains as Grids and EVs scale up
Sustainable battery manufacture needs supply chains that minimise gaps and maximise resilience. Rebecca Martineau at NREL describes their Lithium-Ion Battery Resource Assessment Model (LIBRA) that guides investments and research to make sure the growth of grid storage and EV batteries continues uninterrupted. LIBRA tracks the movement of lithium, cobalt, nickel and other elements through the supply chain, and is designed to adapt to … [Read more...]
Poorly defined âefficiencyâ incentives birthed the SUV. Beware the same mistake with âclean energyâ jobs, âdomesticâ batteries + more
Financial support for the transition needs clear and carefully chosen definitions of what qualifies for that support. Getting it wrong leads to unintended consequences, some which may not reduce emissions, explains James Sallee at the Energy Institute at Haas. Ever wondered why SUVs and big cars proliferated after the 1970s in the U.S. (and are on roads all over the world now)? The 1970s oil crisis triggered new rules that penalised fuel … [Read more...]
Li-ion Grid Batteries arenât always the best replacement for Gas Peakers
Gas peakers need to be replaced with something cleaner. Like grid batteries. But the question is âwhenâ, says Maximilian Auffhammer at the Energy Institute at Haas. Summarising his co-authored paper, he explains that a review of 19 gas peakers in the U.S., replaced with Li-ion grid-scale batteries, reveals only 5 make economic and climate sense (i.e. a positive net present value after including monetised climate and human health impacts). … [Read more...]
Geothermalâs full potential: 24/7 power everywhere, storage, environmental mineral extraction
Geothermal is not just for generating energy. It can be used for storage and extracting minerals too. Kelly MacGregor at NREL summarises the research into taking geothermal to the next level and making it a solution to multiple challenges. Depending on how far down you dig, geothermal is available for running utility-scale power plants as well as heating and cooling individual districts, buildings and houses. And new techniques are being … [Read more...]
âGreen Deal Industrial Planâ explainer: 40%+ of the top low-carbon technologies must be made in the EU by 2030
The ECâs new series of proposed targets and reforms, contained in its Green Deal Industrial Plan, aim to ensure that at least 40% of the EUâs low-carbon technologies will be made within its borders by 2030. The eight âstrategic net-zero technologiesâ are: Solar (power and thermal); Onshore and offshore wind; Batteries and energy storage; Heat pumps and geothermal; Electrolysers and fuel cells; Sustainable biogas/biomethane; CCS; Grid … [Read more...]
âCombustionâ can make cathodes for lithium-ion batteries more cheaply, quicker, using less energy
Burning things produce soot. And that soot contains materials that have been morphed into something else. As Nancy Stauffer at MIT explains, new research there has shown the burning process can be used to produce cathodes far more cheaply, quicker, more simply, and with less energy than the standard method. Itâs another example, from an unexpected direction, of innovations cutting the costs of an essential component of the energy transition: … [Read more...]
