How does green ammonia stack up against hydrogen fuel cells? [Video]

Hydrogen fuel cells are pretty efficient, around 60%. (Less if you consider the energy used to compress that hydrogen to 10,000PSI, but I digress…)

Is the efficiency the killer feature? I’m unconvinced. There are many practical reasons why green ammonia may be the better path forward.

Green ammonia can be made with spare green energy capacity. Many commercially available systems can use it. It should be cheaper at the pump than gas. Sounds like good news!

Nitrogen power (Ammonia) can be made with green electricity from water and air. Ammonia is cheap to store in simple tanks. Ammonia is energy-dense and flammable.

Ammonia looks like a massively scalable green fuel solution. By massively scaleable, I literally mean this could replace all fuels, petrol, diesel, and natural gas power plants. (Unfortunately, I think we would still use propane in BBQs)
