A Bigger Renewable Energy Market than Electricity Grid: Hydrogen Transportation Fuel from Diverse Renewables

摘要

Figures 1,2. Achieving California's "80 x 50" (80% reduction in CO2 emissions from transportation, below 1990 level, by 2050) and other statutory and regulatory goals will require ~ 20 million tons (MMT) per year of high-purity, zero-carbon-emissions, Hydrogen fuel for surface transportation (LDV, bus, goods movement), by Year 2050. This woud require full output of ~ 280 GW of wind. Aviation Hydrogen fuel, if that market develops, would require additional Hydrogen fuel, supporting Gov Brown's ambition to reduce CA's petrol-source transportation fuel use. "80 x 50" cannot be achieved with BEV's; attempting to is technically and economically suboptimal.
