I was impressed by a demonstration of an internal combustion engine 
running on hydrogen.  Pollution measurements of exhaust were CLEANER 
than pollution measurements at the air intake!  The demo was by folks 
from American Hydrogen Association (http://www.clean-air.org/) and 
info about converting engines to hydrogen is at 
http://www.clean-air.org/conversion_kit_response.htm
If I recall correctly, it's a bit like converting an engine to run on 
natural gas.
