The Biogas to Hydrogen projects closely resemble Anaerobic Digester to RNG projects with additional Hydrogen production equipment. These projects utilize RNG with low Carbon Intensity Scores as the primary feedstock to produce hydrogen.
The additional technology deployed for these projects includes a Steam Methane Reformer (SMR) utilizing high-pressure and high-temperature steam, a Water-Gas Reactor, Waste Heat Recovery Generator, and Pressure Swing Adsorption (PSA) Vessels to purify hydrogen to 99.99% purity and above. The reforming conversion ratio from methane to hydrogen typically ranges around 1:2 or 2 cubic feet of hydrogen per cubic feet of methane.
