IMPLICATIONS AND COST OPTIMIZATION OF HYDROGEN INFRASTRUCTURE BUILD-OUT IN CALIFORNIA FOR HEAVY-DUTY TRUCKING APPLICATIONS
Abstract/Contents
- Abstract
- We study the impacts of hydrogen (H2) infrastructure build-out to support the heavy-duty trucking industry in California as the state strives to reach zero-emission vehicle policy targets for emission reductions. We first review the current H2 production, transportation, refueling station, and vehicle technologies used today to foster a hydrogen economy and the technologies in the research and development phase that can accelerate the transition in the future. We then determine the energy and infrastructure impacts of a complete switch of heavy-duty duty vehicles (HDVs) (greater than 8,500 lbs) in California to fuel cell electric (FCEV) from gasoline and diesel fuel sources. Results show that about a 23% increase in natural gas consumption in the state would be required to transition HDVs in the state to FCEVs with steam methane reforming with carbon capture (SMR-CCS) hydrogen production. Alternatively, if the H2 is produced through electrolysis, a 50% increase in electricity generation for the state would be required. If the electricity input for electrolysis is only from installed solar photovoltaic, over four times more capacity than what is currently installed in-state would need to be dedicated to hydrogen production. Also, over two times as much hydrogen storage volume would be needed at H2 refueling stations in comparison to typical gasoline or diesel storage tanks at current gas stations. We next assess the optimal placement of hydrogen production facilities throughout the state to minimize the cost of H2 infrastructure to support HDVs. Qualitative results show that placing SMR-CCS production facilities in Northern California and electrolysis production facilities in Southern California is optimal. Through technoeconomic modeling efforts, we find that lower energy input costs, and larger production facility size yield most cost-effective hydrogen production, distribution, and dispensing costs with SMR-CCS being about $5/kg H2 less than electrolysis hydrogen production in Sacramento, California. Our future work will expand the technoeconomic model to include production costs in each county of California and will account for technology cost reductions as the hydrogen economy grows and technologies mature.
