Electricity Powering Combustion: Hydrogen Engines [PDF]

Proceedings of the IEEE, 2012
Hydrogen is a means to chemically store energy. It can be used to buffer energy in a society increasingly relying on renewable but intermittent energy or as an energy vector for sustainable transportation. It is also attractive for its potential to power vehicles with (near-) zero tailpipe emissions.
