Clean Coal Technology
- Coal Preparation (Coal Washing): Removes unwanted minerals by mixing crushed coal with a liquid, allowing impurities to separate and settle.
- Electrostatic Precipitators: Remove particulates by charging particles with an electrical field and then capturing them on collection plates.
- Coal Gasification: Involves reacting steam and hot pressurized air or oxygen with coal to produce syngas (mixture of carbon monoxide and hydrogen) that is then burned for electricity.
- Wet Scrubbers: Remove sulphur dioxide by spraying flue gas with limestone and water.
- Low-NOx Burners: Reduce nitrogen oxides creation by restricting oxygen and manipulating the combustion process.
Carbon Capture and Storage (CCS)
- Involves capturing and sequestering CO2 from stationary sources like power plants.
- Storage options include geological (injecting CO2 into the earth) and oceanic methods
Carbon Capture Utilization and Storage (CCUS)
- Involves capturing CO2 emissions and either using them to make useful products or permanently storing them underground.
- Supports the hydrogen economy and contributes to a circular economy by converting CO2 into value-added products.
Carbon Sink and Carbon Sequestration
- Natural or artificial reservoirs that accumulate and store carbon-containing compounds.
- Natural carbon sinks include forests, soil, and oceans.
- Carbon sequestration is the capture and long-term storage of atmospheric CO2.
