Reverion Secures $41 Million in Carbon Removal Deals Led by Google, H&M

• Frontier buyers will pay $41 million for 96,000 tons of carbon removals from 2027–2030.
• Reverion’s system removes CO2 from both methane and biogenic CO2, doubling removal compared to conventional biogas use.
• Technology enables decentralized clean power, carbon storage and potential green hydrogen production at farm-scale.

Biogas becomes a new carbon removal frontier

A new set of carbon removal offtake agreements is pushing biogas into the centre of industrial climate strategy, as German climate technology company Reverion prepares to scale a fuel-cell-based process that both generates clean electricity and captures carbon for permanent storage.

Frontier, the advance market commitment founded by Stripe, Alphabet, Shopify, McKinsey and Meta, confirmed that its coalition of buyers will purchase 96,000 tons of carbon removal from Reverion between 2027 and 2030. The deal, valued at $41 million, brings a high-efficiency biogas-to-power pathway into the growing portfolio of engineered carbon removals.

Reverion’s technology uses solid oxide fuel cells (SOFCs) to convert methane-rich biogas into electricity with what the company describes as a record 74 percent electrical efficiency. Unlike conventional combined heat and power systems, Reverion’s process isolates a pure CO2 stream. Both the carbon originating from methane and the biogenic CO2 already present in the gas are captured and liquefied, enabling permanent geological storage.

Governance and climate context

Biogas is often viewed as a circular, low-carbon energy source, but it can still release CO2 and methane when burned or managed inefficiently. Methane traps more than 27 times the heat of CO2 over a century, according to the IPCC’s latest assessment.

Scaling biogas production globally could deliver more than two gigatons of CO2 removal annually, according to Reverion.

How the system works at farm level

Reverion’s units sit directly at biogas plants, typically located on farms that process manure, crop waste and food scraps through anaerobic digestion. The resulting biogas, a mix of methane and CO2, is fed into the SOFC system.

Stephan Herrmann, Co-Founder and CEO of Reverion, described the new offtakes as an important step in proving the business case.

Corporate demand expands beyond tech giants

The buyer list spans global technology firms and a broader set of corporates seeking high-quality carbon removals. Participants include Google, Stripe, Shopify, McKinsey Sustainability, Autodesk, H&M Group, and Workday.

Through Frontier’s partnership with Watershed, additional buyers include Aledade, Canva, Match Group, Samsara, SKIMS, Skyscanner, Wise, and Zendesk.

What executives should watch

For investors and sustainability leaders, the Reverion-Frontier agreement illustrates how quickly the carbon removal market is diversifying.

A pathway with global relevance

As governments look for credible, near-term negative emissions options, biogas-linked carbon capture could play a role in both industrialised and emerging markets.
