Mar 26, 2020 Parts of the coal industry refer to ultra-supercritical units as high efficiency low emissions . However, even HELE coal plants emit around 800tCO2/GWh, according to the World Coal Association. This is roughly twice the emissions of gas-fired electricity and in the order of 50-100 higher than nuclear, wind or solar.
Alternate technology and new products that make the burning of coal easier and less costly are constantly being evaluated. In a modern steam generator, coal has to be first pulverized to the consistency of a very fine powder before it can be burned. There are over 3,000 coal pulverizers in North America grinding millions of tons of coal each day.
