Aluminum–Air Generators for Data Centres Face a Metal Logistics Test
California startup Voya Energy raised $35 million to develop aluminum‑air generators that convert prepared scrap aluminum, air and water into electricity without combustion. The company targets diesel‑powered backup units at data centres, citing advantages over exhaust, noise and permitting constraints, and also envisions continuous‑power installations at grid‑constrained sites. An aluminum‑air cell consumes metal and produces aluminum hydroxide, requiring a supply chain for fuel delivery and by‑product handling that the firm’s specifications omit. Using Voya’s reported 57 % conversion efficiency, [...]
