Membrane technology

Biogas upgrading systems from HoSt use in-house membrane technology, to efficiently upgrade the biogas to biomethane with >99.5% methane recovery – for optimal biomethane utilization. During this process, raw biogas is purified by removing impurities such as CO2 – where selective membranes allow the passage of methane but not CO2. This method offers high separation efficiency and results in the highest possible biomethane yield.
