Every data center has a dirty little secret humming quietly out back: diesel generators. They exist for the worst-case scenario, kicking on when the grid fails to keep servers alive. Now an Israeli company called Phinergy wants to replace them with something that runs on aluminum and air, and it just locked in a partnership with two of the biggest names in tech to prove it works.
Phinergy’s Aluminum-Air Generator technology has been selected by the Net Zero Innovation Hub for Data Centers, a consortium that counts Google and Microsoft among its key stakeholders. The company was chosen from over 70 proposals, which gives you a sense of how competitive the race to clean up backup power has become.
How aluminum and oxygen replace diesel
The core technology is elegantly simple in concept. Phinergy’s AAG systems generate electricity through a chemical reaction between aluminum plates and oxygen pulled from the surrounding air. No combustion, no emissions, no fuel trucks rolling up to top off tanks.
In English: instead of burning fossil fuels during a power outage, these generators essentially consume aluminum. The byproduct is aluminum hydroxide, which can be recycled back into aluminum, creating something close to a circular system.
