Supply-demand strategies for near-term climate benefits from hydrogen in the United States.
Ontology highlight
ABSTRACT: Hydrogen (H2) is a promising energy carrier for decarbonization. However, the greenhouse gas (GHG) mitigation potential of the H2 supply and its adoption across various demand sectors in the US remains unclear. Here, we couple prospective life cycle assessment with a process-based integrated assessment model to evaluate the GHG mitigation of H2 from supply and demand perspectives. Our results show the critical role of H2 production mix in determining supply-side GHG mitigation potential. Without national carbon pricing or large-scale electrolysis in the near future, biomass-based H2 (Bio-H2) emerges as a critical transitional clean H2 production technology. Bio-H2 reduces the life cycle GHG emission int
