Energy storage

Grid-scale batteries are finally taking off — but now supply can't keep up with demand. Here's a recap of what went down in 2022 and a preview of the year ahead.

Long-duration energy storage

The extremely well-funded long-duration storage startup Form Energy found an eager partner in West Virginia’s state government.

Batteries

The startup's granular charging controls can get more energy out of second-life batteries while also detecting and preventing failures that could start fires.

The startup pulled in millions for its novel gravity-based storage design, but most of its deal flow these days comes from garden-variety lithium-ion batteries.

Long-duration energy storage

Some say it's the key to unlocking a decarbonized grid. Will a new pot of federal funding be enough to push long-duration storage into the mainstream?

Lining up a roster of talented project partners is the key to making renewables projects work in smaller communities.

Energy storage

Newcomer Akaysha Energy won backing from investment giant BlackRock and now will build a gargantuan battery in New South Wales.

Batteries

A California pilot project is testing transit buses as a source of mobile backup power. If it works, they could replace dirty diesel generators during blackouts.

Solar

After disasters like Hurricane Fiona, solar panels and batteries can be a lifeline. Energy experts offer some do's and don'ts to help make the most of backup systems during outages.
