A Canadian inventor successfully adapted a car to run on ammonia 40 years ago. Why did governments suppress this technology? Greg Vezina shares how ammonia could finally lead us to a hydrogen economy without building entirely new infrastructure.

His journey began with a single car conversion in the 1980s that sparked four decades of advocacy for ammonia as a cleaner energy alternative. The chairman and CEO of Hydrofuel Canada shares how he successfully adapted a Chevrolet Impala to run on ammonia and drove it across Canada, only to face political roadblocks despite demonstrating the technology's viability.


The most promising immediate applications for ammonia aren't personal vehicles but industrial sectors—cement production, heavy equipment, garbage collection, and shipping. Projects like the UK's Leeds initiative, with offshore wind generators producing ammonia on-site to fuel barges, demonstrate practical integration with existing systems.

Beyond ammonia, Vezina’s team is pioneering photochemistry—using light instead of heat for chemical processes—which could revolutionise hydrocarbon refining without carbon emissions. This breakthrough would allow continued use of existing infrastructure while eliminating pollution, offering a pragmatic transition pathway.

Hi listener. I thought you might enjoy Don Anderson's podcast. Missing Pieces - NPE Life is a podcast that curates stories of and about people who find out, usually through a home DNA test, that someone in their family tree isn't who they thought. They also tell stories of adoptees who've found lost family, or are looking. The host, Don Anderson, found out in 2021 that his dad wasn't his dad. It changed his life. NPE stands for Not Parent Expected or Non Paternity Event.
