Hydrogen is a good alternate fuel because it has a highest calorific value as compared to other fuels.

Hydrogen is considered an alternative fuel under the Energy Policy Act of 1992. The interest in hydrogen as an alternative transportation fuel stems from its ability to power fuel cells in zero-emission FCEVs, its potential for domestic production, its fast filling time, and the fuel cell's high efficiency. In fact, a fuel cell coupled with an electric motor is two to three times more efficient than an internal combustion engine running on gasoline. Hydrogen can also serve as fuel for internal combustion engines. However, unlike FCEVs, these produce tailpipe emissions and are less efficient.
The energy in 2.2 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (6.2 pounds, 2.8 kilograms) of gasoline. Because hydrogen has a low volumetric energy density, it is stored onboard a vehicle as a compressed gas to achieve the driving range of conventional vehicles. Most current applications use high-pressure tanks capable of storing hydrogen at either 5,000 or 10,000 pounds per square inch (psi). For example, the FCEVs in production by automotive manufacturers and available at dealerships have 10,000 psi tanks. Retail dispensers, which are mostly co-located at gasoline stations, can fill these tanks in about 5 minutes. Other storage technologies are under development, including bonding hydrogen chemically with a material such as metal hydride, or low-temperature sorbent materials.
California is leading the nation in funding and building hydrogen fueling stations for FCEVs. As of mid-2018, there were 35 retail hydrogen stations open to the public in California and 22 more in various stages of construction or planning. California continues to provide funding for building the infrastructure, with the Energy Commission having authorization to allocate up to $20 million per year through 2024 until there are at least 100 operational stations. In addition, 12 retail stations are planned for the northeastern states, and some of these should be open by the end of 2018. Non-retail stations in California and throughout the country also continue serving FCEVs, including buses, for research or demonstration purposes. Also, multiple distribution centers across the country dispense hydrogen to material-handling vehicles in their normal operations. Vehicle manufacturers are only offering FCEVs to consumers who live in regions where hydrogen stations exist.
