While hydrogen and fuel cells represent a promising pathway to reduce the environmental footprint of the United States transportation on road transportation system, in order to fully achieve these benefits, the hydrogen needs to be sourced through renewable or other domestic non-carbon emitting production pathways. This report summarizes the application of chemical process flowsheet analyses and cash flow analyses using DOE's H2A methodology to develop near-term (2015) and longer-term (2025) cost projections for eight solar thermochemical hydrogen production reaction cycles.
