something ive wondered about hydrogen drilling is transport. Do you have to build a pipeline from the well to the haber-bosch plant, or do you put it on a truck, or do you build a new haber-bosch plant at the well? Or can you just drill a well at the haber-bosch plant, like with the method where you inject water to react with the rock idk how restricted it is about the site
I actually don't know, but I'd strongly expect that you'd want to build a new ammonia plant on-site. The idea I'd had was to inject carbonated water - CO2 also gets sequestered geochemically in the same class of reactions, turning hydroxides into carbonates - and then also use more CO2 pulled out of the air to turn raw hydrogen into useful hydrocarbons. The reason here for using the hydrogen instead of shipping it is twofold: you could use some of the hydrogen as both power source and fuel for hot flames to run the release half of a calcium carbonate/calcium oxide-based CO2 capture setup, and because IIRC hydrogen is a right fucker to pipe around between tiny molecules escaping easily and hydrogen embrittlement of steel. So you'd want to use most of it very quickly and close to source, and you could pull off the nitrogen fraction out of the air alongside the CO2.
