Make Hydrogen Happen

Researchers leverage renewable electricity for widespread, distributed hydrogen fuel production

Northwestern University researchers have developed a highly effective, environmentally friendly method for converting ammonia into hydrogen. Outlined in a recent publication in the journal Joule, 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. Northwestern’s technological breakthrough overcomes several existing barriers to the production of clean hydrogen from ammonia.

“The bane for hydrogen fuel cells has been the lack of delivery infrastructure,” said Sossina Haile, lead author of the study. “It’s difficult and expensive to transport hydrogen, but an extensive ammonia delivery system already exists. There are pipelines for it. We deliver lots of ammonia all over the world for fertilizer. If you give us ammonia, the electrochemical systems we developed can convert that ammonia to fuel-cell-ready, clean hydrogen on-site at any scale.”
