This saves on infrastructure since we already have CH4 pipelines, power plants, vehicles etc. If we stop and just produce hydrogen, we need to redesign every single pipeline and plant. Also H2 has the downsides that it is extremely explosive and not very energy dense. Only upside I can think of is that hydrogen is so light that leaks don't tend to pool around the plant.
- jakozaur 3y agoYou argument holds true if you want massive distribution. I believe 100% green ammnoia is first step and for that I just need green H2. No need to redesign anything.
- brutusborn 3y agoI don't think so, the only real limit is reusing existing infrastructure. I think you could put ammonia through most pipelines so that isn't a concern, but you will have to replace generators/engines if you want to use it for storage and produce power from it.
- Sunflower98 3y agoWhy bother? The main use case for hydrogen is energy storage. So you just have a big tanker next to the solar farm that fills up when its producing more than the grid needs, and then burn it when there's less than the grid needs.
- Symmetry 3y agoI think it's pretty implausible that the main use case for hydrogen will be energy storage when so many important industrial processes require a good reducing agent that's either currently hydrogen generated from natural gas or carbon monoxide from coal. Steal production, fertilizer production, etc. It's a pretty large chunk of our current global energy use.
