Doesnt a pound of hydrogen contain less energy than a pound of gasoline?
Back to FAQs No. In fact a pound of hydrogen contains 3 times as much energy as a pound of gasoline. However, liquid hydrogen is only one-tenth as dense as gasoline, and it must be stored at -253 C, meaning that larger and heavier insulated tanks are needed to store an equivalent amount of energy. One of the biggest development initiatives will be the development of practical fuel tanks for storing hydrogen on vehicles. Today, hydrogen tanks allow a BMW 745H-V8 to have a range of 350 km between hydrogen fill-ups. With ongoing development, that range can only increase.
