Australian researchers develop new hybrid plasma electrocatalytic process to produce green ammonia Chemical engineers at UNSW Sydney and University of Sydney have developed a hybrid plasma electrocatalytic process for the production of sustainable (“green”) ammonia. The method makes green ammonia from air, water and renewable electricity and does not require the high temperatures, high pressure and huge infrastructure currently needed to produce this essential compound. Traditional production of ammonia via the Haber-Bosch process consumes about 2% of the world’s energy and accounts for 1% of the industrial world’s carbon dioxide emissions. The new production method—demonstrated in a laboratory-based proof of concept—also has the potential to play a role in the global transition towards a hydrogen economy, in which ammonia is seen as a possible solution to the problem of storing and transporting hydrogen energy.
