    RE: Clyde Hydrogen demo of integrated decoupled electrolyzer prototype.

    ⬇️Claim "Safety-no possibility of #hydrogen and #oxygen mixing"

    HD Hyundai HHI now has ammonia-fueled 2.2MWe & 5.4MWe dual-fuel DI ICE engines.↙️

    Hyundai claims a Selective Catalytic Reduction #SCR system will eliminate toxic ammonia & nitrogen oxide emissions.↘️

    -They need high temperatures (around 200C - 250C) to work, leading to high temporary ammonia & NOx emissions.
    -The Immediately Dangerous to Life or Health #IDLH concentration for ammonia is 300 parts per million (ppm)! #woops
