New technique seamlessly converts ammonia to green hydrogen
18 Nov 2020 at 11:17am
Researchers have developed a highly effective, environmentally friendly method for converting ammonia into hydrogen. The new technique is a major step forward for enabling a zero-pollution, hydrogen-fueled economy. The idea of using ammonia as a carrier for hydrogen delivery has gained traction in recent years because ammonia is much easier to liquify than hydrogen and is therefore much easier to store and transport. This technological breakthrough overcomes several existing barriers to the production of clean hydrogen from ammonia.
