IGCC technology offers a number of important environmental benefits:
- IGCC has the potential for the best emission characteristics among coal-based technologies.
- IGCC provides for efficient removal of sulfur compounds, particulates and mercury
before the gas is burned instead of removing the compounds from the exhaust gases
following combustion.
- Nitrogen oxide (NOx) emissions are on a par with emissions from a conventional coal-fired
plant equipped with state-of-the-art emission controls.
- Emissions of carbon dioxide are comparable to emissions from a conventional coal
plant. However, should future environmental regulations require the removal of CO2,
an IGCC plant can separate and sequester CO2 from the process at a significantly
lower cost than conventional technologies.
- The IGCC process requires about one-third less water than a pulverized coal plant
- The IGCC process generates less solid waste than a conventional coal plant.
- IGCC plants enjoy greater fuel flexibility than conventional coal plants. IGCC plants
can utilize various coal types, biomass, and other refinery by-products.

IGCC turns coal into a gas, and then removes impurities from the coal gas before
it is combusted.
