Can Green Ammonia Be a Climate Fix?

[QUOTE="Ygggdrasil, post: 6607005, member: 124113"] I'll repeat [URL='https://www.physicsforums.com/threads/an-ammonia-economy-for-energy-transport-and-storage.951445/post-6025918']my post from the previous thread [/URL]here: A lot of the issues with the potential for a future "hydrogen economy" that was touted in the early 2000s applies to the idea of these ammonia fuel cells. See [URL]https://www.technologyreview.com/s/402584/hype-about-hydrogen/[/URL] for a nice discussion about some of the issues with the idea of a hydrogen economy. A few additional thoughts: 1. Ammonia is not a primary energy source. The article discusses using solar energy to produce ammonia. So, the question is, is ammonia generation the most efficient use of that solar energy? In the US and many other countries, one would have greater environmental and health benefits from using solar energy to displace coal-fired power plants, than say, to generate ammonia to displace gasoline in vehicles. 2. Intermittency is a major issue with renewable energy sources like wind and solar, so storing excess energy as ammonia during off peak hours so that it can be burned later could have benefits. However, there are many other ideas and technologies for storage, and it's not clear how ammonia-based technologies would compare. It's certainly worth continuing research into the technology, but it is by no means clear that the technology will beat out some of the alternatives. 3. Similarly, it's not clear that ammonia-power vehicles would be superior to electric vehicles. Given the existing infrastructure for delivering electricity, there would have to be significant benefits from ammonia fueled vehicles to beat out EV technology. EV technology would likely be more efficient than ammonia fuels as well since you skip the step of converting electricity to ammonia and then to hydrogen as proposed in the Science News piece. The technology does seem to provide a nice alternative to the Haber-Bosch process in a carbon-free future, however. [/QUOTE]
