HYDROGEN OPPOSED-PISTON ENGINE WORKING GROUP

An opposed-piston engine with hydrogen combustion could well provide the best known thermal efficiency from a reciprocating engine, with the potential to match the in-vehicle efficiency of a hydrogen fuel cell. If so, it is a valuable potential option for long haul transit in our quest for sustainable transportation.”
