HYDROGEN GENERATION

while the hydrogen is delivered for end-use applications, with a small amount recycled into the system to power it. Modern Hydrogen’s modular methane pyrolysis units are relatively small, about the size of a shipping container, and can be placed on-site at facilities to generate the energy that powers industrial process energy plants, commercial steam boilers or transportation refueling centers. The technology can also be placed earlier in the natural gas distribution process. For example, in Oregon, the hydrogen that is generated by Modern Hydrogen technology is blended into gas delivery lines at the Northwest Natural distribu tion center and delivered to businesses and homes via Portland’s existing infrastructure. With more than trillion of deployed natural gas assets across the United States, these Modern Hydrogen systems can be easily implemented into existing systems. Additional Technologies for Hydrogen Production Another technology used to produce hydrogen from natural gas is steam methane reforming (SMR) . These projects are being initiated by downstream hydrocarbon industrial companies to remove CO and reduce greenhouse gas emissions (GHG). Pressure Swing Adsorption (PSA) is another process used that separates the hydrogen from o -gas emissions by using two adsorption beds operating in parallel, with one bed puri

structure or inputs. It can draw from the existing natural gas infrastructure already available. Today, the usage of natural gas is comparable to that of coal, nuclear, solar, wind and hydrogen energy sources combined. Notably, natural gas is already composed of about percent hydrogen. Natural gas (methane), RNG or biogas is piped from existing gas pipelines into on-site hydrogen generation units where the gas is heated until it breaks down into solid carbon and hydrogen molecules. The carbon is removed from the system in solid form and can be sold to companies to use in asphalt,
