Reverion raises $175M to scale reversible fuel-cell plants

Reverion builds fuel-cell power plants for utilities, industrial operators and data centers that need electricity when wind and solar aren't producing. The German company closed a $175 million Series B to move that system toward mass production, EU-Startups reported, citing Reverion's announcement.

Its system feeds natural gas, biogas or hydrogen into high-temperature solid-oxide fuel cells, producing electricity without combustion. The same equipment can run in reverse, using surplus electricity to make storable gas. In practical terms, a customer can use one plant for steady generation when power is scarce and energy storage when it is abundant.

The carbon claim depends on what goes in. Reverion says the process separates carbon dioxide in a pure stream for reuse or permanent storage; when the fuel is renewable natural gas, the resulting carbon dioxide is biogenic and the plant can operate carbon-negatively. The company reports measured electrical efficiency of 74.2%.

Data-center operators are one target because a plant can use local gas infrastructure instead of waiting for additional grid capacity, according to the company. Reverion also targets utilities and industrial sites that need controllable output. It says seven plants are already in regular operation at customer sites, with its first international projects scheduled for delivery later in 2026.

The financing was led by Kembara and will pay for an additional production site in Germany as well as development of larger, megawatt-class systems. Reverion plans to increase annual manufacturing capacity tenfold to 250 megawatts. The company says it recently increased output per unit to 500 kilowatts.

Reverion was founded in 2022 as a spinout from the Technical University of Munich, after the fuel-cell concept emerged from doctoral research begun in 2015. Its team in Eresing has recently grown from 100 people to more than 200, and the planned factory could add up to 800 positions, according to the company.
