Larger Compressed-Gas Storage Projects Still Face Poor Economics
A new analysis argues that bigger compressed-gas storage demonstrators, including a 600 MW Chinese plant, have not improved the technology's economic case.
A CleanTechnica analysis revisits compressed-gas electricity storage, a technology its author once called "mostly hot air." The piece acknowledges that the sector has since produced larger demonstrators, including China's 600 MW / 2.4 GWh Huai'an facility, which it says should prompt a reassessment rather than a repeat of old arguments.
Despite that nod to progress, the article's headline and framing are clear: the economics have not improved. The author suggests that while the scale of projects has grown, the fundamental cost and efficiency challenges remain unresolved, leaving compressed-gas storage still on shaky financial ground.
This is a single-source perspective, so the claims reflect one analyst's view rather than a consensus. Still, the piece highlights a key tension in the energy storage sector: bigger pilots can demonstrate technical feasibility without proving commercial viability.
