The U.S. Department of Energy's (DOE) Clean Hydrogen Production Standard (CHPS) Guidance establishes a greenhouse gas emissions target of ≤4.0 kgCO2e/kgH2 for clean hydrogen. It endorses various production methods, including fossil fuels with carbon capture and renewables, aiming to reduce supply chain emissions and sync with global hydrogen markets.
The U.S. Department of Energy's (DOE) Clean Hydrogen Production Standard (CHPS) Guidance document outlines the initial Clean Hydrogen Production Standard developed to meet the requirements of the Infrastructure Investment and Jobs Act of 2021. The CHPS defines "clean hydrogen" as hydrogen produced with a carbon intensity equal to or less than 2 kilograms of CO2-equivalent per kilogram of hydrogen produced at the site of production. The guidance sets a well-to-gate lifecycle greenhouse gas emissions target of ≤4.0 kgCO2e/kgH2, supporting diverse feedstocks and considering technological and economic feasibility. This target aligns with various hydrogen production methods, including fossil fuels with carbon capture, utilization, and sequestration (CCUS); hydrogen-carrier fuels; renewable energy resources; and nuclear energy. The guidance also emphasizes the DOE's commitment to creating and strengthening the production, processing, delivery, storage, and use of clean hydrogen, with a focus on reducing emissions across the supply chain and integrating with global hydrogen markets (Pages 1-6).
