摘要：

The cost of hydrogen delivery for transportation accounts for most of the current H-2 selling price; delivery also requires substantial amounts of energy. We developed harmonized techno-economic and life-cycle emissions models of current and future H-2 production and delivery pathways. Our techno-economic analysis of dispensed H-2 costs guided our selection of pathways for the life-cycle analysis. In this paper, we present the results of market expansion scenarios using existing capabilities (for example, those that use H-2 from steam methane reforming, chlor-alkali, and natural gas liquid cracker plants), as well as results for future electrolysis plants that use nuclear, solar, and hydroelectric power. Reductions in greenhouse gas emissions for fuel cell electric vehicles compared to conventional gasoline pathways vary from 40% reduction for fossil-derived H-2 to 20-fold for clean H-2. Supplemental tables with greenhouse gas emissions data for each step in the H-2 pathways enable readers to evaluate additional scenarios. (C) 2021 Hydrogen Energy Publications LLC.
