Energy storage poised for “rapid growth” in US, with between 130GW to 680GW diurnal storage capable of integrating 80% share of renewables by 2050.

An eight-hour duration lithium-ion battery project was recently selected as a long-duration energy storage resource by a group of energy suppliers in California. Girish Balachandran, CEO of Silicon Valley Clean Energy, tells us about the deal and what it signifies.

A seasonal heat storage plant which will have a capacity of about 90GWh looks set to begin construction next year in Vantaa, Finland, with water stored in underground caverns heated to 140°C using renewable energy and waste heat.

A massive “green hydrogen hub” adjacent to a coal power plant in Utah could get over half a billion dollars in US government loans to support its development.

Tesla CEO Elon Musk has said that the company is already achieving “good margins” on the residential Powerwall product, but that “some additional work is needed” for its utility-scale Megapack to do so.

California’s goal of reaching 100% emissions-free retail electricity by 2045 is achievable, but will require huge deployments of long-duration energy storage, especially from 2030 onwards.

The drive towards longer duration energy storage will likely be multifaceted, with different technologies finding their place both in front of and behind the meter.

The repercussions of Texas’ Winter Storm events in February, may be felt for years. Scott Burger, Annie Baldwin, Jason Houck and Marco Ferrara at long-duration energy storage start-up Form Energy discuss how in-depth system modelling of current and future grids offers some early takeaways which might help prevent the next crisis and how multi-day energy storage could play a leading role.

The UK needs “robust energy storage technologies and clear strategies for implementing them,” to accelerate the transition towards decarbonisation, the lead author of a new roadmap detailing the role of energy storage technologies in the country over the next 10-15 years has said.

Enabling longer duration storage and non lithium-ion technology, what to do with the storage capabilities of electric vehicles and how the industry is overcoming regulatory hurdles were all key topics discussed at this year’s Energy Storage Summit in London.
