The CaFCP is a voluntary program, which aims to begin readying the market for FCEVs. Fuel cell electric vehicles are considered ZEVs if they are fueled with hydrogen that is stored on-board the vehicle. Fuel cell electric vehicles that use liquid fuels with an on-board reformer can have extremely low levels of emissions, and therefore can qualify for partial ZEV credit. Like all fuels, hydrogen has energy and needs to be treated with respect. Because hydrogen is lighter than air it disperses very quickly.
Manufacturers are committed to building fuel cell vehicles that meet or exceed safety standards.
The hydrogen is delivered to the fuel station as a liquid and stored in a 4,500-gallon tank. As fuel is needed it is vaporized and warmed to about 20 degrees below ambient temperature. Then it is compressed to 6250 psig and stored for use. Two dispensers provide the hydrogen to the cars at either 3600 psig or 5000 psig. Introducing such an entirely new technology requires great know-how and resources.
