OCTA Hydrogen Fueling Station



LDG served as engineering consultant to partner developer Trillium for the design and construction of a hydrogen vehicle fueling station for the Orange County Transit Authority (OCTA) in Santa Ana, California. The Santa Ana station, one of a handful currently in operation in California, provides hydrogen fuel for OCTA public transportation buses that have converted to run on the environmentally-friendly, clean-burning fuel option. The facility is one of the largest hydrogen fueling stations in the country, dispensing 1,500 kg/day with the capabilities of increasing to 3,000 kg/day. As a fueling station this size is not commonly constructed, special techniques were utilized to maintain quality fueling. The techniques included designing and installing refrigerant and expansion loops underground to maintain optimal temperature of the hydrogen during fueling and the complex integration of the hydrogen dispensers within an existing fueling island with CNG and diesel dispensers. A special code review with authorities and suppliers was provided to design a safe, compliant fueling area.
