New fuels for climate-neutral marine transportation

Methanol, ammonia, and hydrogen are waiting in the wings to replace problematic heavy fuel oil in ship propulsion systems. In this interview Nicole Wermuth and Andreas Wimmer explain the differences between the three variants, and look at the design requirements for the engines that will burn them.
