Abstract
This paper discusses the conceptual design of a scalable and reproducible hydrogen fueling station at Santa Monica, California. Hydrogen production using renewable energy sources such as biogas, which accounts for 100% of the total production, has been discussed. The fueling station consists of a direct fuel cell (DFC) 300 fuel cell for on-site generation of 136kg/day of hydrogen and 300kW of electric power, five hydrogen storage tanks (storage capacity of 198kg of H2 at 350 and 700bar), four compressors which assist in dispensing 400kg of hydrogen in 14h, two hydrogen dispensers operating at 350bar and 700bar independently and a SAE J2600 compliant hydrogen nozzle. Potential early market customers for hydrogen fuel cells and their daily fuel requirements have been computed. The safety codes, potential failure modes and the methods to mitigate risks have been explained. A well-to-wheel analysis is performed to compare the emissions and the total energy requirements of conventional gasoline and fuel cell vehicles.
