A system for delivering hydrogen to a vehicle is provided which includes a first hydrogen generator coupled to a first compressor. A second hydrogen generator is also provided that produces hydrogen gas at a pressure at least 2 times that produced by said first generator. Coupled to the second hydrogen generator is a second compressor that increases the pressure of the hydrogen gas produces to a desired delivery pressure. A storage vessel is coupled to both first and second compressors to store the hydrogen gas at a desired pressure level prior to dispensing.
