Описание:

GERMAN Rail (DB) and Australian energy company Fortescue Future Industries (FFI), a subsidiary of Fortescue Metal Group, are working together to develop an emissions-free ammonia-hydrogen engine as an environmentally friendly alternative to diesel engines for locomotives and rail vehicles.

Ammonia was one of a range of alternative fuels proposed during a debate at InnoTrans last month, which was chaired by DB head of technology TecLab, Dr Tobias Fischer, and also included DB Cargo green transformation lead, Mr Jörg Schneider, and FFI port and rail engineering manager, Mr Rubim de Moura.

The ammonia-hydrogen engine is based on an existing diesel engine that will be modified to run on green ammonia and hydrogen produced from renewable energies. The advantage compared with a pure hydrogen engine is that ammonia has a higher energy density than liquid hydrogen and is easier to transport and store.

A so-called “cracker” from the Stuttgart-based company Ammonigy is a key part of the technology of the ammonia-hydrogen engine being trialled by DB and FFI. This splits a small part of the ammonia outside the engine into hydrogen and nitrogen, with the resulting hydrogen then mixed with the remaining ammonia as an ignition gas which ensures CO2-free combustion.
