In brief

  • Phinergy aluminum-air generators chosen from 70+ proposals by Net Zero Innovation Hub for Data Centers
  • Technology generates electricity through aluminum-air chemical reaction, producing recyclable byproducts
  • Phinergy secured binding agreement to scale systems toward megawatt-level data center deployment
  • Google and Microsoft consortium stakeholders pursuing carbon-free and carbon-negative operations

How the technology works

Phinergy's aluminum-air generator systems generate electricity through a chemical reaction between aluminum plates and oxygen pulled from the surrounding air. The byproduct is aluminum hydroxide, which can be recycled back into aluminum, creating something close to a circular system. This approach eliminates the combustion and emissions associated with traditional diesel generators.

Path to deployment

A binding agreement has been formalized between Phinergy and the consortium, with the project's trajectory pointing toward scaling aluminum-air generator systems to megawatt-level capacity. The company's momentum accelerated in August 2025, when Phinergy entered a partnership with Rosendin, a major American electrical contractor. Rosendin's role is to help integrate the systems into data center infrastructure across the US.

Phinergy previously secured a $1.5 million grant through the BIRD Energy program, a US-Israel collaboration, working alongside the New York Power Authority. That funding helped validate the technology's potential before the consortium's selection.

Market context and momentum

Google has pledged to run on carbon-free energy around the clock. Microsoft has committed to being carbon negative. Both companies face the challenge of powering massive data center operations while meeting these climate commitments. Diesel backup generators, which kick in during grid outages, undermine those goals—making clean alternatives like Phinergy's system strategically valuable.

Following the consortium announcement in July 2025, Phinergy's stock surged approximately 180%, including a single-day jump of over 35%. Phinergy CEO Emmanuel Levy framed the selection as validation of the company's approach to clean energy backup power, signaling confidence in the technology's commercial viability at scale.
