Hydrogen power is an exciting form of clean energy. But hydrogen typically needed to be produced in a lab using energy-intensive methods. White hydrogen, a newly identified hydrogen source, could eliminate the need for lab production.

    I read some interesting stuff about how Japan plan to create green hydrogen and convert it into ammonia to send through their existing gas infrastructure. For a variety of reasons for Japan it makes a lot of sense to go all in on hydrogen. It’s also a super interesting way for grid scale Energy storage in Europe. There’s plenty of sun and wind when it’s sunny or windy, using existing gas infrastructure to handle renewably generated ammonia could be a quick win to be able to build up strategic reserves during net positive energy days.

      That does sound interesting, but its no hydrogen as a fuel source (like the article), its used in your description as a single link in a chain. So they’re creating hydrogen from a process (likely electrolysis) using some other energy source, then nearly immediately converting that hydrogen into ammonia for better storage and transport. That would be a good use of hydrogen, as an intermediate step and not a beginning and end step.

        Yeah that’s exactly it. Create hydrogen and convert it into ammonia in places with ready access to renewables, then send it and store it via gas infrastructure to where it’s needed, and burn it to create power. It’s less efficient than straight h2, but the benefits of being able to transport it and store it make up for that. Japan’s grid is crazy fractured and they went heavy into gas, so for them it’s kind of a no brainer to invest in that tech.

        If you Google around there lots of more detailed reporting on the whole process and plan. I can try and dig up the very insightful comment I read on tildes which had lots of citations too if you’re interested.
