Recent debate in both government and technical forums has focused on the value, the possibility, and the timing of meeting future transportation fuel demands by use of hydrogen generated from renewable sources of primary energy. The justifications for and the criticisms against development of renewable energy supplies and hydrogen-fueled propulsion systems are reviewed, and the hurdles to be overcome in creating such a future vision are identified. If the vision of a hydrogen-fueled transportation system is to become reality, significant material inventions and developments will be required. The opportunities for critical materials research programs in the areas of hydrogen generation, fuel cell development, and hydrogen storage are described. The status of General Motors’ progress in development of hydrogen-fueled, fuel cell-powered vehicles is used to demonstrate the potential that a clean, renewable-hydrogen fuel-based transportation system can provide in meeting societal goals.
