About the Research Area

A significant challenge facing the agricultural sector is continuing to grow while counteracting environmental emissions. The crops we grow are dependent on a good nitrogen supply in the soil. Natural fixation of atmospheric nitrogen occurs through bacteria in the soil and lightning. Modern agriculture utilises nitrogen-based fertilisers, and while modern fertiliser industry has many advantages they also have challenging environmental problems of energy demand and a significant greenhouse-gas footprint associated with it. Natural occurring nitrogen fixation through lightning can be mimicked in a more controlled tailored manner using electrically produced man-made plasmas. These plasmas can be sustained in ambient air, and convert atmospheric nitrogen, oxygen and water into nitrates and ammonia. Plasma processes are also investigated for organic waste valorisation.
