Circularity Fuels successfully converts biogas into syngas in compact unit

In California, Circularity Fuels has successfully converted biogas from a California Central Valley dairy farm into synthesis gas (syngas), a key precursor to sustainable aviation fuel (SAF), using a compact electric processing unit one-hundredth the cost of conventional steam methane or autothermal reformers.

The successful demonstration marks a major step toward transforming the economics of renewable fuel production, one that Circularity believes will help airlines meet mandates for sustainable fuel alternatives while unlocking billions of dollars in new revenue streams for farmers. America’s 20,000+ large livestock operations generate nearly a trillion pounds of manure each year, yet fewer than 6% of them capture the biogas that is produced as the waste decomposes.

Circularity announced that its proprietary, electric-powered Ouro Reactor successfully processed raw biogas from a working dairy farm’s covered lagoon digester, converting methane and carbon dioxide that would typically be flared or vented into valuable fuel components. Unlike traditional gas-fired reformers that cost millions and require massive infrastructure, the Ouro Reactor uses modified automotive-industry components to achieve the same result at a fraction of the size and cost.
