Phinergy & Rosendin to deliver zero-emission backup power
Phinergy and Rosendin have entered a partnership to provide aluminium-air backup power systems for data centres and microgrids.
This pairing brings together Phinergy's aluminium-air generator technology and Rosendin's experience in energy infrastructure and large-scale data centre projects, aiming to introduce a fossil-free alternative to diesel generators for backup power in the North American market.
Zero-emission focus
The aluminium-air generator (AAG) uses aluminium as its energy source, providing electricity with zero emissions at the point of use. The system is intended for megawatt-scale applications, offering multi-day resilience for mission-critical data centre operations and supporting fast-shifting loads driven by artificial intelligence applications.
With increasing pressure on data centre power requirements and decarbonisation targets, companies are searching for solutions that align with environmental, social and governance (ESG) standards. The AAG is positioned as a replacement for fossil-fuel powered backup generators, aiming to enable data centre operators to achieve net-zero commitments without compromising operational reliability.
Market deployment
Rosendin brings its history in the US data centre market to support the scale-out of Phinergy's technology. The two companies have outlined plans to deploy the aluminium-air systems across major data centre and microgrid projects in North America, targeting rapid adoption in one of the world's most power-intensive sectors.
"This collaboration with Rosendin marks a pivotal step in scaling Phinergy's aluminum-air technology for the data center industry-one of the most demanding and fastest-growing energy markets," said Emmanuel Levy, CEO, Phinergy. "Rosendin's strong market presence and deep expertise in mission-critical infrastructure give us a clear path to scale and connect with the right customers. By joining forces, we're not just replacing diesel-we're setting a new benchmark for clean, resilient power in the AI era."
The partnership leverages Rosendin's relationships with major data centre operators as well as its expertise in deploying large-scale infrastructure projects. The companies expect this to facilitate quicker market entry for aluminium-air backup solutions.
Data centre demands
Data centre operators are under pressure from both growth in artificial intelligence demand and tighter regulatory scrutiny of energy usage. According to Rosendin, backup power is now a limiting factor for data centre expansion plans.
Phinergy's AAG offers a solution to clients seeking decarbonised backup power options as regulations and owner requirements increase.
"Rosendin has spent the past six years examining on-prem power systems as alternates or enhancements to Utility-provided power," said Bill Mazzetti, SVP, Rosendin. "Our clients simply need more power, and without it, development stops dead. This is a reply to the major expansion of data center and large loads, combined with a continuing demand for decarbonized power from owners and jurisdictions. The Phinergy AAG sits in a unique position to meet this need, and we're thrilled to be their partner in the development and deployment of this solution."
