For the first time in history, renewable energy is cheaper than fossil fuels. But there’s still a fundamental problem: the sun doesn’t always shine, and the wind doesn’t always blow.
For industries that need reliable energy 24/7, that makes storage one of the biggest challenges to a renewable-powered future.
One potential answer? Carbon.
This technology uses carbon as the storage material for a thermal battery—taking advantage of its low cost, massive existing supply chain, and high energy density.
The vision is ambitious: abundant energy powered by wind and solar, stored until it’s needed, and delivered on demand without emissions.
Here’s how long-duration energy storage could help make that future possible.
