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

Remarks.

#IDLH for Phosgene is ~02ppm.

See
https://www.cdc.gov/niosh/idlh/75445.html

The RECOMMENDED level of Phosgene is ZERO ppm

The naturally occurring levels of Phosgene are ZERO ppm.
