4. Applications
Coal gasification can be used to produce a wide variety of products: electricity, chemicals, natural gas substitutes (NG) and synthetic fuels. It is of strategic interest against a backdrop of tense oil and gas markets.
4.1 IGCC + CCS
The IGCC (Integrated Gasification Combined Cycle) is a combination of gasification and combined cycle (gas turbine + steam turbines). Its advantage over a conventional coal-fired power plant is greater electrical efficiency, thanks to the performance of the gas turbines. What's more, this scheme enables easy desulfurization of the gas before combustion, and authorizes CO2 capture (CCS CO2 capture and storage ) under good economic conditions ("clean coal" concept).
IGCC technology is well known, but numerous developments are underway...
