BIOGASUpgrade Biogas to Biomethane with Efficient Electrolytic H2
Biological methanation converts the CO2 fraction of biogas into additional methane using green hydrogen. IONZERA-equipped electrolysers provide the low-cost H2 that makes this process economical.
Membrane Cross-Section
PSU-TiO₂-GOMore Methane from Every Biogas Plant
Raw biogas contains 35-45% CO2. Adding green H2 via methanation converts this CO2 to CH4, increasing biomethane output by up to 70% without additional feedstock.
Lower H2 Production Cost
IONZERA's 3x lower area resistance reduces the cost of the hydrogen input, the primary variable cost in biological methanation, improving the economics of biogas upgrading.
Compact Electrolyser Integration
IONZERA's thin profile enables compact electrolyser stacks that fit within the footprint constraints of existing biogas plant sites, simplifying retrofit installations.
Biogas Upgrading with Green Hydrogen
Biogas produced from anaerobic digestion of organic waste typically contains 50-65% methane and 35-45% carbon dioxide. Conventional upgrading removes the CO2, wasting this carbon content. Biological methanation offers a superior alternative: adding green hydrogen to convert CO2 into additional methane via the Sabatier reaction, catalyzed by methanogenic archaea.
This process can increase biomethane output by up to 70% from the same feedstock, significantly improving the revenue of biogas plants. However, the economics depend heavily on the cost of electrolytic hydrogen, making electrolyser efficiency a critical factor.
Electrolyser Requirements for Biogas Plants
Biogas plants have specific characteristics that influence electrolyser and membrane selection:
Nanocomposite Structure
PSU-TiO₂-GOLower Resistance
Thinner Profile
Circular Economy Benefits
By converting biogas CO2 to methane using renewable hydrogen, the combination of IONZERA-equipped electrolysers and biological methanation creates a truly circular energy system. Organic waste becomes a high-value energy carrier, renewable electricity is stored as biomethane, and CO2 is utilized rather than vented.
