[AI-Driven Electricity Demand Spurs Investment in Long-Term Energy Storage: Cloud Giants Like Google and Meta Invest More in Carbon Dioxide and Iron-Air Batteries] (1) The surge in electricity demand brought about by artificial intelligence has spurred billions of dollars in clean energy investment, including next-generation geothermal power generation and advanced nuclear reactors. (2) Now, major cloud giants are investing more in another clean technology: long-term energy storage batteries. (3) In Arizona, Google's parent company, Alphabet, is collaborating with the Italian company Energy Dome to achieve 10 hours of energy storage using carbon dioxide batteries. (4) Crusoe Energy is collaborating with the startup Form Energy to deploy iron-air batteries; these batteries utilize the chemical reaction between iron, water, and oxygen in the air to complete the storage and release of electrical energy, with a lifespan of up to several days. (5) Meanwhile, Meta has reached an agreement with Noon Energy, another long-term energy storage provider in California, to deploy an energy storage system: by decomposing carbon dioxide into carbon compounds and oxygen, and then reversing the reaction to generate electricity, it can achieve 100 hours of renewable energy storage. (6) Amanda Yang, head of clean energy at Meta, said: “Ultra-long-term energy storage really helps to achieve a clean and stable power supply. Four-hour energy storage can do very little.”
