Decarbonization scenarios for California and other regions to 2030 and 2050 show very significant adoption of plug-in electric vehicles and hydrogen-powered fuel cell vehicles (for both light-duty vehicles and also freight trucks), as well as substantial investments in large quantities of renewable wind and solar generation. Moreover, hydrogen generation from renewable electricity possesses traits that concurrently facilitate the penetration of green generation and a zero-carbon fuel source. Hydrogen energy storage (HES) and power-to-gas systems, as well as controllable electric vehicle charging, present an opportunity to increase flexibility and resiliency of the sustainable energy supply system while potentially decreasing system cost and emissions by better utilization of renewables. As a result of these two important trends, there is likely to be a convergence of the electricity and transportation fuels sectors. This work will investigate the system-wide benefits of electric vehicle charging and hydrogen production on the high-renewable penetration grids that are expected in the 2030-2050 timeframe. It investigates the impact of demand side flexibility from charging electric vehicles and producing hydrogen for fuel cell vehicles on the ability to decarbonize the electricity grid with intermittent renewables. Moreover, the researchers will explore different scenarios to understand the interactions of the Western U.S. electric grid and fuel sector through energy storage technologies (specifically HES), power-to-gas systems, and flexible EV charging from a system-wide perspective. |
