High-Efficiency, Low-Emissions Coal Plants: Come HELE or High Water - GE
IGCC. Integrated gasification combined cycle (IGCC) is a technology that uses a high-pressure gasifier to convert coal or other carbon-based fuels into pressurized gas. The synthesis gas (syngas), a mixture of carbon monoxide, carbon dioxide, and hydrogen, can be used to drive a combined cycle turbine, a cleaner way of burning coal.
