Frontier, the advanced market commitment consortium backed by companies including Google and Meta, has agreed a major carbon removal deal with German biogas carbon-capture firm Reverion. Under the agreement, Frontier buyers will pay $41 million for the removal of 96,000 tonnes of CO₂ between 2027 and 2030.
Reverion uses solid oxide fuel cells (SOFCs) to convert methane from biogas into electricity, producing CO₂ in the form of steam as its only by-product. The captured CO₂ is then liquefied and transported for permanent geological storage. Frontier’s head of deployment, Hannah Bebbington Valori, said the technology offers a “smart upgrade to a well-known industrial process”, noting that with more than 120,000 biogas sites worldwide, Reverion’s approach could unlock large-scale carbon removal while improving farm operations.
Reverion claims its system captures all carbon contained in biogas — not only the CO₂ — effectively doubling removal potential. The company also reports a 74% fuel-to-electricity conversion efficiency. The units can switch to hydrogen production when electricity prices fall, offering farmers an additional revenue stream during periods of excess renewable power.
Reverion CEO Stephan Herrmann said the Frontier deal demonstrates the economic viability of the firm’s approach, adding: “Our technology converts biogas to electricity at 74 percent efficiency while capturing carbon for permanent storage. We’re focused on scaling this solution globally.” The company says it is positioned for rapid growth, with 60 signed pre-orders and 120 letters of intent.
The agreement adds to a series of recent purchases by Frontier, which aims to accelerate high-quality carbon removal technologies. In July, the consortium signed a $41 million deal with BECCS developer Arbor for 116,000 tonnes of carbon removal credits to be delivered between 2028 and 2030. Earlier, in March, it agreed a $33 million contract with enhanced rock weathering firm Eion for 78,707 tonnes of CO₂ removal between 2027 and 2030.
