Reverion Raises $175M to Scale Carbon-Negative Power Plants Tenfold

Reverion has closed a $175 million Series B round to scale production of its solid oxide fuel cell power plants tenfold, expanding annual manufacturing capacity to 250 megawatts at a new German facility that will add up to 800 jobs. The round, led by Kembara, the deeptech and climate fund managed by Mundi Ventures, brings in Allianz, KfW Capital, Aurum Impact and Carbon Equity as new investors alongside existing backers Extantia, Energy Impact Partners, UVC Partners, the European Innovation Council Fund, alfa8 and Possible Ventures. Reverion's technology has demonstrated a world-record electrical efficiency of 74.2 percent in live customer operation, nearly double that of conventional generators, while capturing pure biogenic carbon dioxide that makes the plants carbon-negative when running on renewable natural gas.

 

A Dispatchable Alternative to Intermittent Renewables

 

Reverion's core pitch addresses a structural weakness in wind and solar power: neither generates electricity on demand, which forces grids and heavy industry to keep fossil-fueled backup capacity on standby. The company's solid oxide fuel cell technology converts gas into electricity electrochemically rather than through combustion, and the same hardware runs in reverse as an electrolyzer, converting surplus electricity into storable gas when power is abundant and converting gas back into electricity when it is scarce. That reversibility lets a single asset respond to price signals in both power and gas markets rather than sitting idle between demand peaks.

The carbon accounting depends on fuel source. When the plants run on renewable natural gas, the captured carbon dioxide is biogenic, meaning the facility removes more carbon than it emits over its operating cycle. Seven commercial plants are already running at customer sites, with per-unit output recently upgraded to 500 kilowatts, and the company says its commercial pipeline now exceeds $2 billion in revenue potential, a figure that points to demand outpacing the tenfold manufacturing expansion the new capital is meant to fund.

Positioning Around the Data Center Power Crunch

 

Reverion is explicitly targeting the strain that AI-driven data center growth is placing on electricity grids, where new facilities increasingly face multi-year connection delays and public opposition tied to their environmental footprint. Running on local gas infrastructure lets a data center operator install generation on-site rather than wait for grid expansion, giving it firm power that is insulated from electricity market price volatility and, when fueled by renewable gas, carries a carbon-negative rather than carbon-neutral profile. That framing directly targets hyperscale operators who face pressure to secure large, reliable power supplies without abandoning stated climate commitments.

The bet is that data center demand becomes Reverion's largest growth market rather than its original biogas customer base. Co-founder and COO Felix Fischer said the company is seeing accelerating international demand as utilities and industrial customers conclude that genuine energy security requires dispatchable clean power, and that the new capital is intended to help clear its existing order backlog while pushing the company toward long-term profitability.

Manufacturing Scale-Up Outpaces the Company's Own Recent Growth

 

The majority of the new funding is earmarked for a megafactory in Germany that will lift annual manufacturing capacity from current levels to 250 megawatts, a tenfold increase intended to keep pace with the $2 billion pipeline. Reverion's headquarters team in Eresing has already more than doubled this year, growing from 100 to over 200 employees, and the new site is expected to add as many as 800 further positions. First international project deliveries are scheduled for later this year, extending the company's footprint beyond its home market in Germany.

Co-founder and CEO Stephan Herrmann said the financing lays the foundation for industrial mass production and will allow the company to scale its product into the megawatt class, opening markets beyond its current biogas and data center customer base. Robert Trezona, climate lead at Kembara, said the growth opportunity lies specifically in powering data centers, where Reverion's negative carbon footprint matters as much as its efficiency record, since hyperscalers need large, reliable power without compromising climate commitments. Whether Reverion can execute the tenfold manufacturing scale-up on schedule, while continuing to grow headquarters staff and clear a pipeline several times larger than its current production capacity, will determine whether the company can convert its efficiency record into the volume its investors are now betting on.
