A decarbonized grid, powered primarily by solar and wind, will require a lot of energy storage. Lithium-ion batteries, while the technology du jour, won't come close to solving the impending problem on their own.
The long-duration energy storage dilemma is multi-pronged: today's market structures don't adequately reward energy storage of longer than four hours, and potential solutions are mired in technical challenges and steep capex costs.
But one company may have cracked the code.
Episode 45 of Factor This! features Robert Piconi, CEO of Energy Vault, a company well on its way to deploying long-duration gravity storage systems at scale.
Energy Vault first made its splash with towering cranes lifting and lowering blocks under the guiding principles that have made pumped hydro the world's most significant energy storage resource.
Now, with a redesigned concept, the company is deploying its systems in partnership with major players like Enel… and even landed a green hydrogen deal with Pacific Gas & Electric, California's largest utility.
Can long-duration energy storage finally break through?
