Ford is developing hydrogen combustion engines along with fuel cells.

FORBES: Hydrogen Gas

The technology isn't new-a patent for a hydrogen internal combustion engine was issued in 1928, and a 20hp fuel-cell tractor was demonstrated in the late 1950s.

FORBES: Magazine Article

It's powered by a hydrogen internal combustion engine that turns a 44-kilowatt electric generator that runs eight propellers and whatever communications equipment is loaded on board.
