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...]
Machine learning cuts new EV battery design testing times by months, years
Normally, battery prototype testing can take months and years to find the optimal design for fast-charging and battery life. Now scientists from Stanford, MIT and the Toyota Research Institute have developed a machine learning programme that can cut battery testing times by 98%. They’ve applied it to EV batteries. The faster a new and improved design is proven and taken to market the more rapid the uptake of EVs we’ll have. Matthew Vollrath at … [Read more...]
Lithium-Sulphur batteries: cheaper, greener, hold more energy
The rapid expansion of electric power across the world is putting a strain on battery production. The standard lithium-ion battery depends on minerals and metals in limited supply, so alternatives are needed urgently. Mahdokht Shaibani at Monash University describes the work of her team on developing lithium-sulphur batteries. There are many advantages, not least the abundance of sulphur, the 16th most common element on Earth. Added to that, … [Read more...]
The 7 battery technologies that can be cost competitive by 2030 for EVs to grids
Rapid performance improvements, falling prices and massive investment is accelerating us towards a time when batteries undercut fossil fuels for storage and despatch, right across the board, according to a report by Rocky Mountain Institute. The authors, Charlie Bloch, James Newcomb, Samhita Shiledar and Madeline Tyson have made forecasts for 7 battery technologies: the current leader Li-ion as well as Li-Metal, Li-Sulphur, Zinc, High … [Read more...]
Can Vanadium Flow Batteries beat Li-ion for utility-scale storage?
It’s taken 40 years for lithium-ion battery technology to evolve into its current state, powering everything from the smallest electronic devices to Tesla’s 100MW battery farm in southern Australia. But utility-scale Li-ion batteries are rare. 99% of grid storage today is pumped hydro, a solution that will always be limited by geographical and environmental constraints. For utility-scale chemical batteries to take off they need a new technology, … [Read more...]
Utility-scale batteries can undercut peaking gas and coal
A report by IEEFA looks at trends in the U.S. to install utility scale batteries. The report’s author, Dennis Wamsted, gives examples of how it is replacing the peaking and seasonal generation being provided by gas and coal. Emissions aside, the numbers are starting to add up. In Hawaii the combination of solar generation and storage is expected to undercut the price for fossil fuel generation. In Texas, Vistra Energy’s batteries are soaking up … [Read more...]
The European Battery Alliance is moving up a gear
Europe needs batteries, primarily for clean mobility and grid stabilisation. But EU lithium-ion cell manufacturing is less than 3% of the global share, and mainly for high-end niche markets, not the automotive sector. If Europe doesn’t act fast, catching up with Asia will become impossible, writes Carole Mathieu of the IFRI’s Centre for Energy, reflecting the views of the European Battery Alliance (EBA). It’s a strategic imperative, given the … [Read more...]
Barriers to intermittent renewables and battery storage come tumbling down
The astonishing growth of the renewable energy sector shows little sign of slowing, as costs continue to plummet, along with the cost of energy storage, to remove many of the barriers to using intermittent renewable generating sources in a range of applications. Much of this is down to the fact that the cost of battery energy storage is one third lower than this time last year. … [Read more...]
Competitive battery storage: InnoEnergy doubles prize to accelerate start-ups entry to market
Utilities and other investors are putting more funds than ever into a battery storage market worth an estimated $250 billion. Right on cue, European clean energy innovation engine InnoEnergy announced a global call for storage entrepreneurs. Their €100,000 first prize meant applications from a diverse range of start-ups flooded in. But which of these should be fast-tracked into this competitive market? At a special event which highlighted a … [Read more...]
Utilities are starting to invest in big batteries instead of building new power plants
There has been a dramatic drop in battery costs in recent years. Jeremiah Johnson and Joseph F. DeCarolis, of North Carolina State University, say if this continues grid-scale batteries could supplant the usual solutions to peak electricity demand: gas power plants and transmission lines. Inevitably, this will depend on the future price of gas, and the changing policy environment. But one thing is for sure: utilities don’t want to invest in peak … [Read more...]
