The biogas company Biofrigas has launched a solution for refueling liquefied farm-produced biogas.The concept is called Cryosep for purification, upgrading, and liquefaction of biogas as part of a larger installation where the other parts of the installation have been delivered by other parties. The solution is based on the strong interest that the company says it has observed from farmers and haulage companies for refueling liquefied farm-produced biogas directly on the farm.
