Several organizations, encompassing companies, research labs, and academia, have come together to form the Hydrogen Opposed Piston Engine Working Group. The organization is a collaborative forum to advance sustainable transportation technology.
“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,” said James Turner, professor of mechanical engineering, clean combustion research center, King Abdullah University of Science and Technology. “If so, it is a valuable potential option for long haul transit in our quest for sustainable transportation.”
The organization says it hosts a series of meetings among its members to exchange research results, insights and ideas.
“The direct-injection two-stroke engine could be a very promising and interesting option for hydrogen combustion to achieve zero NOx because of its advantages of high-power density and inherent much lower NOx emissions,” said Pierre Duret of DI2S Consulting & Training and former director Powertrain and Sustainable Mobility, IFP School (France). “These two-stroke advantages are even more significant with an opposed-piston engine thanks to its higher power density and efficiency.”
