Thousands of new nuclear reactors would be needed to produce the hydrogen required to meet America's energy needs.
"Americans may not realise how close the country is to making a gigantic bet on a nuclear future...Anti-nuclear activists want hydrogen fuel to come from renewable energy sources, such as wind power. However, that arithmetic doesn't work...Based on the Energy Information Administration's estimate of 2025 fuel imports (measured in quads, or quadrillion British thermal units), the output of 300MW per VHTR reactor, and the comparative efficiency of hydrogen fuel compared to gasoline, you come up with a requirement of about 4,000 reactors."
