H2 TECHNOLOGIES GREEN H2 TECHNOLOGIES Green H2 is defined as H2 Electrolysis. Electrolysis is the primary method of green H2 produced from non-fossil fuel sources and with a zero (or even negative) total lifecycle carbon intensity of the production pathway. Current commercial methods of green H2 of water, steam methane reforming (SMR) of bio-methane, and thermal or photocatalytic conversions. production are the electrolysis Electrolysis is the only green H2/low-carbon pathway that production. This process entails the use of an electric current to split water (H2 O) into H2 and oxygen gases using a device called an electrolyzer. When renewable or other (green) zero-carbon electricity is used to power electrolysis, the process produces net-zero carbon H2 The success of H2 fuel (i.e., green H2 omy is incumbent on cost-effective green H2 ). as a pathway for a decarbonized econproduction. is anticipated to reach cost-efficiency targets in the nearand mid-term. In the long term, other technologies, such as biomass or waste-based processes and direct solar energy processes, may be expected to become cost-competitive. In the past decade, electrolyzer costs have declined 60% and are expected to fall 40% in the short term and 80% in the long term. According to the International Ener
