Renewable Hydrogen Station at Joint Base Pearl Harbor-Hickam

HCATT manages the U.S.’s first renewable hydrogen station on a military base, located at the Joint Base Pearl Harbor-Hickam in Hawaii. The station can store up to 380kg of compressed hydrogen at pressures up to 10,000psi. The hydrogen station can generate up to 12 kg of hydrogen a day when connected to the adjacent 146kW solar array and can produce up to 65kg of hydrogen a day when power is provided by the utility. The station provides fuel for the alternative fuel vehicle demonstrations program with the Hawaii National Guard.
