Edited sentence: Bush administration in 2001.Hydrogen can also be obtained through electrolysis of water, the environmental effect of which depends on the energy source used for the electrolysis, this process however requires 3 times the energy had the electricity simply been stored in a battery and used directly in an electric vehicle.It is worth noting that hydrogen is not readily available in significant quantity in nature, and is usually obtained from hydrocarbons such as natural gas through steam reforming, thus maintaining dependence on the petroleum industry.The focus of the FreedomCAR initiative is, nominally, to fund research too risky for the private sector to engage in, with the long-term goal of developing effectively emissions- and petroleum-free vehicles
