Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group. The Working Group consists of members undertaking research and development in the field of hydrogen combustion in an opposed-piston engine. The only criteria emission of concern is NO x.

Green, the Hoyt Hottel Professor in Chemical Engineering, is developing a technology that allows liquid organic hydrogen carriers (LOHCs) not only to deliver hydrogen to the trucks, but also to store the hydrogen onboard. A team of MIT researchers led by William H. Proposed process flow diagram for onboard dehydrogenation.

Researchers in China have developed a novel free-piston linear generator (FPLG) to recover exhaust waste heat efficiently from a vehicle engine. The FPLG can be used in a small-scale organic Rankine cycle (ORC) system and can directly convert the thermodynamic energy of working fluid into electricity. —Tian et al.

Secondary organic aerosol (SOA) is a major component of fine particulate matter—which causes adverse health effects—even in urban environments; vehicles may be a dominant source of SOA in urban areas, although there is still an ongoing debate over SOA formation from on-road sources. —Zhao et al.

Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances.
