@kritter461 That's not true. Several of the Hydrogen Hubs in the use from the IRA are focused on ammonia. Canada has all of its commercial green hydrogen plants being built to produce ammonia, in this case specifically as an energy export.

@docal2 you probably don't mind when you're at an ice rink, which yes is less than large-scale storage, you're at the rink so it's rather moot. But ammonia storage is quite safe. As much so as Natural Gas.

@kritter461 No outside very low mix rates into Natural Gas it's not reasonable for residential distribution, I agree. And even that is questionable. But for industrial heating and electrical production it's practical. When stored as ammonia.

@tysi2011 thank you for the comment sense, I don't know how people can act like 3 times the space in the Sahara is equal to farm land or forest. Let alone the higher capacity factors that makes it more like 2 to 1.

@karmo0o178 there is an ammonia cell that's been demonstrated and is being commercialized in Denmark that has as low an energy as a state of the art Methane to ammonia plant, no Carbon Capture included. It uses more electrical energy, whereas the methane plant uses mainly thermal, and that's arguably less expensive, although peak solar or wind energy prices change that. Now, are likely producing in a Gulf state, for cheapest possible solar energy, so you're competing against very inexpensive NG. Imo it (or something very like it) is going to be one of the top 10 most important technologies of the next 30 years. It would even work alongside something like fusion. One of my biggest questions on the future is what we'll do with all the extra available oxygen. If you're interested, it works by using a solid oxide electrolysis cell to seperate the Oxygen from a mix of steam and air. Oxygen from the air moves across the Membrane, and water breaks down into hydrogen and oxygen, which also crosses the membrane. The mix of hot Hydrogen and the nitrogen still in the air can then directly be converted to ammonia, switch saves money on not requiring an Air seperation unit to remove the oxygen from the air and having to produce green hydrogen seperately to then react converting the operation to a single stage. Look up Haldor Topsoe if interested.

@kritter461 and that may be foolish. But when you say the problem with Hydrogen is storage, you're talking about a specific use case, when it can be and is planned to be stored as ammonia.

@Tom_McMurtry Toyota has been betting big on Hydrogen because Japan has no access to battery input material. It's based on government policy. Also it's closer to existing engines
