Reverion Raises $175M Series B to Scale Production of its Dispatchable, Carbon-Negative Power Plants Tenfold

• Reverion builds world-record efficiency solid oxide fuel cell (SOFC) power plants that generate electricity from gas, provide flexible energy storage through reversibility and can be run carbon-negative.

• Led by deeptech and climate fund Kembara, the company has closed a Series B of $175 million.

• Allianz, KfW Capital, Aurum Impact and Carbon Equity are joining as new investors, alongside existing backers Extantia, Energy Impact Partners, UVC Partners, European Innovation Council Fund (EIC Fund), alfa8 and Possible Ventures.

• The capital will fund the further scaling of the technology, a new production site in Germany with 250 megawatts of annual manufacturing capacity and up to 800 jobs.

• Reverion positions itself as the answer to the rapidly growing power demand of data centers – delivering sustainable, baseload-capable power generation on site.

Eresing, Germany, September 29, 2026 – As global grids struggle with the intermittency of wind and solar and AI-driven data centers face crippling power shortages, Reverion has closed a Series B funding round of $175 million to scale production of its dispatchable, carbon-negative power plants. Operating at a world-record electrical efficiency of 74.2% – measured in live customer operation with the first units from pre-series production – nearly double that of conventional generators, Reverion’s technology converts renewable gas into on-demand electricity with zero emissions, while capturing pure biogenic CO₂. The round is led by Kembara, Mundi Ventures’ European scale-up fund that backs breakthrough deeptech and climate technologies. Allianz, KfW Capital, Aurum Impact and Carbon Equity are coming on board as new backers alongside the existing investors. The company will invest the majority of the funds raised in the new production site, which is set to increase manufacturing capacity tenfold.

Fixing Intermittency: Clean Power On Tap

Solar and wind are vital, but their intermittency leaves grids vulnerable and forces heavy industry to rely on fossil-fueled backup power. Reverion provides the missing link: the Holy Grail of energy – a truly dispatchable renewable energy source that combines the clean credentials of renewables with the round-the-clock reliability of a conventional generator. Reverion’s solid oxide technology converts gas electrochemically into electricity, without combustion, and captures the CO₂ in the fuel stream in pure form that can be reused or permanently stored. Where the fuel is renewable natural gas, that CO₂ is biogenic, and the plant is carbon-negative in operation. The same system runs in reverse: in electrolysis mode, it converts surplus electricity into storable gases, giving operators a flexible asset that responds to price signals in both the power and gas markets.

Stephan Herrmann, CEO and co-founder of Reverion, says: “Solar and wind give us clean energy, but only when the weather cooperates. What the world needs is clean power on tap. By closing this Series B, we are laying the foundation for industrial mass production. We are building the dispatchable, carbon-negative engine that allows grids and heavy industry to run 100% clean, 24 hours a day, 365 days a year. The financing allows us to build an additional production site and to scale the product further, into the megawatt class. That opens up entirely new markets for Reverion.”

Solving the AI Data Center Power Crunch

Demand for Reverion’s systems is expanding rapidly beyond biogas sites into the technology sector. Energy-intensive data centers are facing severe grid connection delays and mounting public pushback over environmental impacts. Reverion provides an immediate, on-site energy solution. By running on local gas infrastructure, Reverion allows data center operators to circumvent grid bottlenecks and secure continuous, firm power, turning energy-hungry infrastructure into a carbon-neutral or even carbon-negative asset. This power supply is independent of price volatility in the electricity market and unconstrained by the pace of grid expansion.

"We are seeing explosive international demand for our systems as utilities and industrial customers recognize that true energy security requires dispatchable clean power," adds Felix Fischer, COO and co-founder. "With seven commercial plants operating in the field and output per unit upgraded to 500 kW, this capital ensures we can rapidly clear our backlog and steer the company toward long-term profitability."

$2 Billion Pipeline & German Megafactory Expansion to Create 800 Jobs

To meet a commercial project pipeline exceeding $2 billion in revenue potential, Reverion is investing the majority of the capital into a new megafactory in Germany. The facility will scale manufacturing capacity tenfold to 250 megawatts annually. At the company’s headquarters in Eresing, the team has recently grown from 100 to more than 200 employees; up to 800 further positions will be added at the new site. Seven power plants are already in regular operation at customer sites. Demand is rapidly expanding beyond Reverion’s home market in Germany, with the first international projects scheduled for delivery later this year.

“Solid oxide fuel cells are the most efficient way to convert gas into electricity, and Reverion sets the global benchmark in this field,” says Robert Trezona, Climate Lead at Kembara. “The growth market lies in powering data centers, where Reverion’s negative carbon footprint counts as much as efficiency. Hyperscalers need massive, reliable power, but they cannot compromise on their climate commitments. With this round, we are financing industrial-scale expansion.”

About Reverion

Reverion builds reversible fuel cell power plants for decentralized energy supply. Founded in 2022, the company is based in Eresing near Munich and employs more than 200 people. Its container-based systems generate electricity from biogas, natural gas, or hydrogen and, in electrolysis mode, convert surplus electricity into storable gases. According to the company, its measured electrical efficiency of 74.2 percent makes it the world’s most efficient thermal power plant. Carbon-negative operation is possible when biogas is used.
