Renewable energy is now cheaper than fossil fuels. But there’s still a major challenge: the sun doesn’t always shine, and the wind doesn’t always blow.
For factories and other industrial facilities that need reliable power 24/7, renewable energy needs a way to be stored and delivered on demand.
One potential solution is surprisingly simple: carbon.
Carbon is inexpensive, widely available, and highly energy dense—making it a promising material for thermal batteries that can store wind and solar energy for long periods of time.
The ultimate vision? Abundant, inexpensive, zero-emissions energy available whenever and wherever it’s needed.
Here’s how long-duration energy storage can help make that possible.
