Hydrogen may never be feasible as a fuel for vehicles, but BMW is pushing ahead anyway with an advanced hydrogen-gas combustion hybrid.
The internal combustion engine in BMW’s new hydrogen-gasoline hybrid engine can switch seamlessly between the two fuels. And control systems optimize the concentrations of hydrogen being burned, which can minimize or eliminate one of the downsides of hydrogen combustion: the formation of nitrogen oxides. While BMW hopes its new model will help drive the adoption of hydrogen in vehicles, experts are skeptical. (Credit: BMW)
