Researchers in Germany have recently unveiled a hydrogen-powered engine that could challenge diesel in some of the toughest applications by operating without emissions and achieving efficiency levels above 60 percent. Developed by a research team at the Otto-von-Guericke University Magdeburg, the so-called hydrogen cycle engine operates in a closed loop and reuses most of its working gases after each cycle.
The project was led by Hermann Rottengruber, PhD, a professor at the university’s Institute for Engineering of Products and Systems (IEPS). It was also backed by the Federal Ministry for Economic Affairs and Energy of Germany.
