    Hey @nolanews -
    1) Sorry, but hydrofluoric acid is the same as hydrogen fluoride #HF ↙️
    2) It does not take HEAVY CONCENTRATIONS of HF to burn the skin and cause organ damage. 3ppm HF is the Immediately Dangerous to Life or Health concentration #IDLH from @niosh !↘️

    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.↘️

    NOTE: SCR systems are ineffective on cold starts!
    -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
