MAN presents hydrogen roadmap; use in fuel cells and combustion engines

Green Car Congress

Apart from the rapid development of battery technology, hydrogen is a good complementary option as an alternative fuel for long-distance transport. MAN is testing both the use of a fuel cell and an H 2 combustion engine. When in use, fuel cells do not cause any climate-damaging emissions, as they only emit water vapor.
