Frontier has facilitated offtake agreements with Reverion, a German company that captures and permanently stores CO2 from biogas while generating clean electricity through solid oxide fuel cells (SOFCs). Under this agreement, Frontier buyers will pay Reverion USD 41 million to remove 96,000 tons of CO2 between 2027 and 2030.

Technology Overview

Reverion's fuel cells convert biogas from waste into clean electricity while capturing all carbon, both from methane and CO2. This technology achieves record-high biogas-to-electricity conversion rates and doubles carbon removal compared to conventional approaches. The system captures carbon from both methane and CO2 in biogas while generating clean electricity.

The approach offers dual benefits: enabling decentralized clean electricity generation at biogas sites and providing a near-term solution for carbon removal at scale. Reverion's technology addresses inefficiencies in conventional biogas utilization by capturing carbon that would otherwise be released into the atmosphere.

Environmental Impact and Potential

Methane is a potent greenhouse gas, trapping over 27 times more heat than CO2 over 100 years, according to IPCC AR6. Conventional biogas utilization technologies, such as combined heat and power plants, use the raw gas less efficiently, leading to CO2 and, sometimes, methane emissions.

Scaling biogas production worldwide could remove over 2 gigatons of CO2 annually. This potential represents a significant opportunity for large-scale carbon removal through expanded biogas infrastructure.

Comparison to Conventional Methods

Reverion's technology differs from conventional biogas utilization approaches in several key ways. Traditional combined heat and power plants use raw biogas less efficiently, resulting in CO2 and, sometimes, methane emissions. In contrast, Reverion's solid oxide fuel cell technology captures carbon from both components of biogas, methane, and CO2, effectively doubling the carbon removal compared to conventional approaches.

The company's approach addresses the limitations of existing biogas technologies by ensuring complete carbon capture while maintaining electricity generation capabilities. This represents a significant advancement over current biogas utilization methods that allow carbon emissions to escape during the energy conversion process.
