A future powered by sustainable energy sources could save the world from devastating climate change and reduce energy bills. But renewable energy has an intermittency problem — the sun provides no power at night, while winds can stop suddenly. Better battery storage — a holy grail for scientists worldwide — is considered key to solving the intermittency problem by storing energy when the wind and sun are strong. But current storage solutions, including lithium-ion batteries and pumped hydro, are expensive and challenging to scale. What if surplus renewable energy could be stored as computation instead?
