Climate startup Reverion announced a series of offtake agreements facilitated by carbon removal buyer coalition Frontier, to capture and permanently store carbon from biogas, using Reverion’s fuel cell technology.

Under the new agreements, Frontier buyers including Google, McKinsey, H&M and others will pay Reverion $41 million to remove 96,000 tons of CO2 between 2027 and 2030.

Founded in 2022 as a spin-off from the Technical University of Munich, Reverion provides a solution to produce clean energy, while also capturing carbon from methane and CO2 emitted from fuel made from biomass waste such as manure, crop waste, and food scraps. The company’s solid oxide fuel cell system receives methane and CO2 biogas produced by farmers using anaerobic digesters, and converts the methane into electricity, with the pure CO2 stream byproduct liquefied and transported for permanent storage in geological formations.

According to Reverion, by capturing carbon from both methane and CO2, the company’s approach doubles removal from biogas, compared to conventional approaches, in addition to enabling decentralized clean electricity generation at biogas sites, allowing farmers to reduce fuel use, cut costs, and generate additional revenue. Reverion added that its system can switch to electrolysis mode when electricity prices are low at times of peak solar and wind power production, in order to produce green hydrogen, providing an additional revenue opportunity for farmers.

Stephan Herrmann, Co-Founder and CEO, Reverion, said:

“This offtake with Frontier buyers allows us to demonstrate that our approach to carbon removal can be economically viable on top of driving climate impact. Our technology converts biogas to electricity at 74% efficiency while capturing carbon for permanent storage. We’re focused on scaling this solution globally.”

Buyers participating in the carbon removal purchase agreements include Stripe, Google, Shopify, and McKinsey Sustainability, Autodesk, H&M Group, and Workday. Additionally, through Frontier’s partnership with Watershed, companies including Aledade, Canva, Match Group, Samsara, SKIMS, Skyscanner, Wise, and Zendesk will also participate.

Hannah Bebbington Valori, Head of Deployment at Frontier, said:

“Reverion’s approach is a smart upgrade to a well-known industrial process—turning biogas waste into clean power while capturing all the carbon, not just part of it. With over 120,000 biogas sites worldwide, this approach could unlock hundreds of millions of tons of carbon removal while also improving farmer operations.”
