The world’s first ammonia-powered zero-emissions tractor efficiently accomplished its first demonstration run on the Superior Power Heart at Stony Brook College in New York final week. The midsized John Deere tractor had its diesel engine changed with an “ammonia to energy” system developed by a startup referred to as Amogy. The system converts the energy-dense chemical into hydrogen, which then powers a 100 kW hydrogen gas cell.

Though most EV protection is dedicated to consumer-oriented passenger automobiles and lightweight vehicles, medium- and heavy-duty autos signify greater than 1 / 4 of US car emissions and are vital targets for decarbonization. The low-energy density of batteries and their lengthy charging instances make gas cells a beautiful zero-emissions resolution, and we have regarded on the potential makes use of for hydrogen gas cells in trains, trucking, and mining previously.

However even the greenest hydrogen nonetheless is not very vitality dense, and outdoors of California there’s little hydrogen infrastructure to depend on.
