Air Products Introduces New Dual-Pressure Capable Hydrogen Fueling Station; First Public-View 700 Bar Station in US
Air Products and the University of California, Irvine (UCI) unveiled a new dual 700 and 350 bar (10,000/5,000 psi) pressure capable vehicle fueling station on the UCI campus.
The 700 bar fueling station is the first in the United States to be sited at a location with wider accessibility for vehicle fueling demonstrations. The station is also the first deployed by Air Products as part of the California Hydrogen Infrastructure Project (CHIP) with the United States Department of Energy (DOE), along with project collaborators Toyota, Honda, BMW and Nissan.
One way for hydrogen vehicles to achieve a greater range between refuelings is through vehicle on-board storage at higher pressures.
This is really a milestone project in the continued development of fueling station technology. The dual-pressure dispensing capability allows drivers to select the pressure at which to refuel their hydrogen fueled vehicles. This station is the first in California and the United States with the ability to dispense hydrogen at varied and advanced pressures, and to be sited in public view.—Ed Heydorn, business development manager for Air Products
The fueling station features non-interchangeable fueling nozzles, which reduce the potential for user error. The stand-alone dispenser features a familiar gas station-like interface designed for ease of use and safety. The fueling station has a capacity of 25 kg per day—about five to ten fills, depending on vehicle capacity. Computerized vehicle communications help optimize the refueling process, and vehicle fill times are approximately three to six minutes for both fueling pressures.
Vehicle communications help optimize the fill by allowing the station to monitor tank temperature and pressure during the fueling process. Hydrogen can be dispensed with or without vehicle communications.
The gas supply for the station comes from trucked-in liquid hydrogen.
Air Products designed, engineered, installed, and will maintain the dual pressure station with funding from the DOE and California’s South Coast Air Quality Management District. Planning is underway for the addition of a separate liquid dispensing unit which can directly fill vehicles that carry liquid hydrogen on board as a fuel.
Toyota, Honda, and Nissan’s hydrogen fuel cell vehicles and BMW’s hydrogen internal combustion engine vehicle, which uses liquid hydrogen, anticipate fueling at the station. The National Fuel Cell Research Center at UC Irvine operates the station, which is open to authorized users in furtherance of the DOE project. Air Products has installed prior 700 bar stations for private use at vehicle original equipment manufacturer facilities.
The CHIP program is a DOE-sponsored multi-year project led by Air Products to demonstrate a model of real-world hydrogen infrastructure and to acquire sufficient data to assess the feasibility of achieving some of the nation’s hydrogen infrastructure goals. To accomplish this, several hydrogen fueling stations employing a variety of hydrogen production methods are planned in the greater Los Angeles area, including the station at UCI.
