Policies like the “green” labelling of EV batteries would give a significant advantage to European manufacturers, as well as accelerate the cleaning up of the supply chain. EU firms are better than most foreign battery manufacturers at monitoring and reducing emissions, writes Carole Mathieu at the IFRI Centre for Energy & Climate, referencing her report “Green Batteries: A Competitive Advantage for Europe’s Electric Vehicle Value Chain?” The … [Read more...]
Understanding battery costs better: Li-ion costs have dropped 97% in 30 years
There are two revelations here. First, quite how dramatically lithium-ion battery costs have dropped since 1991 – by 97%. Second, that nobody could agree on how big that drop has been. Agreement on that number – and an established procedure to therefore make good forecasts - is vital for policy makers and related clean energy players. They need to know how much of a role batteries can play in the electrification of transport as well as storage … [Read more...]
Create new laws to help bring Battery manufacturing to Europe
Europe should start leading battery manufacturing instead of leaving it to China, argue Alex Keynes and Cecilia Mattea at Transport & Environment. With laws spreading across the continent to make electric vehicles compulsory for new car purchases, this is a growing and strategic market. But a firm grip on battery manufacture emissions, as well as ethical sourcing and recycling, has to be part of the plan. The authors give a template of what … [Read more...]
Battery innovation must drive the 50-fold increase in storage capacity needed by 2040
The IEA has set the storage sector a challenge. It says the world will need 10,000 GW-hours of batteries and other forms of energy storage by 2040, a 50-fold increase on today. The good news is that a joint study by the European Patent Office and the IEA reveals electricity storage patenting activity has grown 14% a year over the past decade. Here the IEA summarises the findings of its comprehensive report. It explains that Japan and Korea lead, … [Read more...]
Research into solid electrolytes to improve performance of lithium-ion batteries
If the limits of lithium-ion battery performance are indeed being reached, one way forward is to extend those limits with new materials. Mark Shwartz at Stanford University describes their research into solid electrolytes, which promise to be more energy dense than the standard liquid form. To identify the best compounds, artificial intelligence and machine learning were used rather than the usual and much lengthier trial-and-error experimental … [Read more...]
Grid scale Battery costs are declining faster than Wind and Solar
Gas as a transition fuel for grids may be around for a lot less time than we thought. We already know that large batteries, if they are cheap enough, can replace gas plants to provide peaking power to grids reliant on intermittent wind and solar. Bruce Robertson at IEEFA says the numbers are showing battery costs declining even more rapidly than wind and solar. Precisely because of that increased competitiveness Australia’s AGL Energy is starting … [Read more...]
“Vertical well” Pumped-Storage Hydro: small, cheaper, 1-to-100MW range
In the U.S., pumped-storage hydropower (PSH) already provides 95% of all utility-scale energy storage. So any innovations that cut costs or extend PSH usability should be well received. The National Renewable Energy Laboratory (NREL) and its partners Obermeyer Hydro, Microtunneling Inc. and Small Hydro Consulting are demonstrating the advantages of a small pump installed in a vertical “well” rather than an underground powerhouse, one of the most … [Read more...]

On July 15th 2020, Energy Post hosted an online panel discussion with Dr. Florian Ermacora (European Commission), Professor Ad van Wijk (TU Delft), Marcel Steinbach (BDEW) and Giulia Branzi (SNAM). At the event, video recording below, readers heard a summary of the proposals for Europe's new Hydrogen and Sector Integration strategies direct form the Commission, insights from van Wijk on how supply will come as much from outside as from within the … [Read more...]
Batteries’ next challenges: fast charging, vehicle-to-grid, long duration, second life
Li-ion battery storage costs continue to fall dramatically. But for batteries to fulfil their potential, particularly for grid storage, developers need to focus on fast charging, electric vehicle-to-grid capability, long duration storage and second-life batteries, explains Madeline Tyson at Rocky Mountain Institute. She runs through the different types of Li-ion batteries, their strengths and weaknesses, how they can be harnessed to address these … [Read more...]
2019’s grid storage additions fell for the first time since 2013. Why?
Globally, new installations of grid storage fell year-on-year in 2019 for the first time since 2013. This IEA summary of the landscape is taken from its latest series of Tracking Clean Energy Progress reports. The IEA’s recommendations reflect the fact that grid storage is new and complex, needing changes to existing regulations and market rules that are unviable in the age of transition. The policy goal is to monetise the value of storage in … [Read more...]
Grid-scale Solar PV storage can use re-purposed old EV batteries
Once an EV battery has declined to 80% of its original capacity it is considered too weak for continued vehicle use. Recycling the battery – at that point - to make another one is expensive. MIT’s David Chandler describes how researchers there have run experiments and models to show that old EV batteries can instead be packed together and used as backup storage for grid-scale solar PV installations. It’s cheaper than building new Li-ion battery … [Read more...]
Europe needs its own EV battery recycling industry
Europe needs its own battery recycling industry, and the EU’s European Battery Alliance should make it happen, says Raphaël Danino-Perraud writing for the IFRI Centre for Energy & Climate. For economic, strategic and environmental reasons, today’s overwhelming dependence on outsourcing – in this case to Asia - for battery manufacture and recycling needs to change. To start with, Asia provides over 90% of global car battery output, half coming … [Read more...]
Grid Battery tech on track. It now needs re-designed markets, monetisation
The rapid expansion of variable renewable electricity generation is making cost effective storage more urgent. Sure enough, in Europe several electricity storage projects are under construction and new ones are announced almost on a weekly basis. The battery technology seems to be on track, with estimates of $156/kWh in 2019 dropping to $61/kWh by 2030. But progress is hampered by the lack of a market that recognises and rewards the true value of … [Read more...]
Pumped Thermal Electricity Storage: grid-scale, cheap materials, known tech, compact, install anywhere
We need to store the huge quantities of excess electricity generated by variable renewables. But what’s the best way? Currently, over 99% of large-scale electricity storage uses pumped hydro dams. But geography severely limits where you can build one. And the growth of grid-scale batteries is limited by raw material costs and short lifecycles. Antoine Koen and Pau Farres Antunez at Cambridge University review an important alternative, Pumped … [Read more...]
Pumped Storage Hydropower 2.0: steel dams, underground, or 1-10MW modular
Pumped Storage Hydropower (PSH) is one of the most cost-effective utility-scale options for grid energy storage. The U.S. has plants across the country, totalling over 20GW of capacity. Now the Dept of Energy (DoE) is backing four teams developing blue sky (water?!) ideas that should make the next generation of PSH even cheaper. In this article the National Renewable Energy Laboratory (NREL) tracks their progress so far. They include dams made of … [Read more...]
