Supercritical & ultra-supercritical coal
Supercritical and ultra-supercritical coal plants run steam above its critical point (~221 bar, ~374°C and higher), raising efficiency and cutting fuel use and CO₂ per MWh versus older subcritical units.
Frequently asked questions
Why are supercritical coal plants more efficient?
Higher steam temperature and pressure extract more work per unit of fuel, so they emit less CO₂ per MWh than subcritical plants.
