Strategies to improve rechargeable zinc metal batteries
A lack of standardized protocols is preventing rechargeable zinc metal batteries from complementing lithium-ion storage tech. A U.S. research team is now calling for standardized protocols for columbic efficiencies and greater zinc/electrolyte stability to make the technology viable.
World’s largest battery storage system now operational
It’s a title that is becoming more contentious by the day, but for the time being, LS Power’s 250 MW Gateway project in San Diego, California, is the biggest storage battery in the world.
A battery chemistry schism is imminent
A report from Wood Mackenzie predicts lithium-iron-phosphate will overtake lithium-manganese-cobalt-oxide as the dominant stationary energy storage chemistry within the decade.
Covid-19 weekly round-up: Differing opinions on energy storage fall-out, a trade show update and some surprisingly positive financials
Negative second-quarter updates from China and uber-low new-solar figures from India, however, show the world is far from out of the woods yet.
Lithium battery equipment makers buffeted by Covid
Grid scale lith-ion batteries may be multiplying Stateside, but an expected recovery in the production line segment will be put on hold until next year because of the pandemic, according to one analyst.
Plans for Norwegian graphite battery factory
Norwegian polysilicon maker and silicon business Elkem is planning to build a manufacturing facility in Herøya.
The ‘rubber-band effect’ on renewable energy project margins
David Riester of Lacuna Sustainable Investments, looks at how, on the journey from concept to monetized power plant, renewables and energy storage projects tend to get tugged toward ‘zero’ margin, from either direction. The further the rubber band is stretched, the stronger the pull back toward zero.
New membrane promises cheaper electrolysis
A novel anion exchange membrane has been developed by German chemical company Evonik. Its creators claim it can make hydrogen generation cheaper, as the cells used for electrolysis featuring the device would not require precious metals.
Energy storage investment to approach $10bn in 2025
Analyst IHS Markit has predicted storage will rebound this year following its first year-on-year decline in 2019. The technology is being rolled out at pace despite Covid-19 with state-level policies set to keep the US the global capital for the next five years.
Aluminum energy storage coming to Abu Dhabi
Swedish start-up Azelio says it will have a pilot project up and running in Masdar City by the end of next month. The technology sees electricity used to super heat aluminum with energy released on demand via a heat transfer fluid to drive a Stirling engine.
