Compressed-Gas Storage Demonstrators Got Bigger. The Economics Didn’t Get Better.
Two years ago I called compressed-gas electricity-storage claims mostly hot air. Since then the sector has produced exactly the sort of evidence that should force a reassessment rather than a repetition of the old argument. China has commissioned the 600 MW / 2.4 GWh Huai’an compressed-air demonstration, Hydrostor has pushed … [continued]

AI Is Climate Tech’s Newest Hype Layer — The Commercial Problems Are Older
Panthalassa raised $140 million this year to build autonomous ocean platforms that would generate electricity from waves and use it directly for AI inference computing at sea. The proposition removes one genuine problem for wave energy: instead of transmitting electricity back to shore through subsea cables and grid connections, put … [continued]

Photovoltaic Windows Have Been Heating Water in a Bucharest Apartment for Two Years
A two-year apartment pilot in Bucharest uses semi-transparent photovoltaic windows to heat domestic water directly in DC, turning an ordinary water tank into thermal storage without a solar inverter or battery. By Adrian Băisan, PhotoVoltaic Windows SRL For people living in apartment buildings, using solar energy is not as straightforward … [continued]

The Grid Needs Storage, Not Every Storage Idea
Grid-storage debates are usually framed as a contest among technologies. Lithium-ion batteries compete with flow batteries, compressed air, liquid air, gravity systems, iron-air and whatever new long-duration acronym has arrived with a funding announcement. That framing skips the more important system question: how much dedicated electrical storage is actually required … [continued]
