| "The raw energy density of liquid ammonia is 11.5 MJ/L,[64] which is about a third that of diesel." https://en.wikipedia.org/wiki/Ammonia#As_a_fuel (Note this is energy density by volume, which is the metric most care about. Energy density by weight of H2 gas is great, but the volume is enormous in comparison.) https://en.wikipedia.org/wiki/Hydrogen_storage Ammonia has been long recognized as a great medium for energy storage and you can generate at the site of electric generation. But the challenge has been extracting the hydrogen from the ammonia. My understanding is that hydrogen crackers exist, but have only been successful commercially at large scale. A portable cracker that you can put on a car that extracts hydrogen on demand from an ammonia storage tank is the innovation we need to see. Apparently there is work in Denmark that looks promising... (And now there is this new membrane technology from Australia.) https://www.mvsengg.com/products/hydrogen/ammonia-cracker/ http://www.ammoniaenergy.org/ammonia-cracking-to-high-purity... Personally, I am cheering for ammonia as a storage means. I am not a fan of batteries found in today's electric vehicles because there are too many conflict minerals in them. Maybe Tesla will succeed mining colbat in Colbat Ontario Canada... But until then, it is probably coming from the Congo or Bolivia. https://www.washingtonpost.com/graphics/business/batteries/c... https://www.bloomberg.com/news/features/2017-10-31/the-canad... |
Yes, but that's assuming you'd burn it, I suppose (not a chemist). In this case, you're extracting H atoms using a different process, and I imagine that this wouldn't utilize the full raw energy density of ammonia.
