Reducing emissions – some options
- Fabric filters (bag houses) to reduce PM2.5
- Flue gas desulfurisation and low sulfur coal to reduce
SO2
- Selective Catalytic Reduction to reduce NOx
emissions
- Coal washing to reduce mercury emissions
- Ultrasupercritical power stations
- Electrostatic precipitators
- Planned retirement, transition to renewables
