Long-duration storage on a compressed timeline

For most of its history, not much changed in compressed air energy storage (CAES). The first plant was deployed in 1978, but the technology never really caught on. Now, with a sudden flurry of record-breaking utility-scale plants coming online in China, increased deployment in Europe, North America and Australia, and growing calls to get off gas, might CAES finally have its moment in the sun?

For years, due diligence in solar and battery energy storage systems (BESS) focused on a familiar set of technical and commercial risks: resources, the grid, permitting, contracts, equipment reliability, and financial assumptions.

But that distinction no longer reflects how projects actually perform, argues Ragna Schmidt-Haupt, partner at Everoze.
