Bennamann are a Cornwall based renewable energy business. Our innovative technology captures and upgrades fugitive methane from dairy slurry lagoons / stores. Crucially, the methane upgrading is done on farm using a mobile processing system. The only technology invested in on the farm are Bennamann’s novel retrofit biogas capture storage covers used on the slurry lagoons or stores.

The better than zero carbon biomethane produced can then be used on farm - in clean power generation and refuelling methane tractors and vehicles. Any excess biomethane is sold off site and the farmer gets a profit share.
