ElumisEnergy

American-made solid oxide fuel cells for clean, on-site data center power.

Early-stage development

Exploded view of a solid oxide fuel cell stack

Power made electrochemically, not by burning fuel.

A solid oxide fuel cell converts fuel directly into electricity through an electrochemical reaction across a ceramic electrolyte. With no combustion, it runs quietly, emits very little NOx or particulates, and reaches electrical efficiencies above 50%, with high-grade waste heat that can be put to work in cooling or combined heat and power.

Elumis Energy plans to design and manufacture SOFC systems in the United States, built specifically for data centers that need firm, scalable power on site. Systems will run on pipeline natural gas today, with a path to biogas and hydrogen as those fuels become available.

Inside an Elumis fuel cell power module

Each module packages fuel processing, the SOFC stacks and power electronics into one factory-built enclosure. Modules ship ready to connect, sit in rows beside the data hall, and add capacity one block at a time as load grows.

Why SOFCs for data centers

  • Firm, on-site powerRuns around the clock, independent of grid interconnection timelines.
  • Modular by designAdd capacity in blocks as data halls come online.
  • Efficient and cleanHigher efficiency than combustion engines with near-zero local air pollutants.
  • Quiet and compactNo large rotating machinery, suitable for sites near communities.
How a solid oxide fuel cell works: air and fuel in, oxygen ions cross the ceramic electrolyte, DC electricity out to the load

Made in the USA, built for the ITC.

Our systems are being designed around a US manufacturing base and a domestic supply chain. Fuel cell property that begins construction from 2026 through 2032 is eligible for a 30% federal Investment Tax Credit under Section 48E of the Internal Revenue Code, and Elumis Energy products are being developed to meet those requirements.

A domestic supply chain also means shorter lead times, supply security and fewer exposure risks from foreign sourcing for our customers.
