IGCC is an integrated gasification combined cycle power generation facility that integrates the gasification facility and the combined cycle power generation facility (combination of gas turbine and steam turbine). JGC has constructed the first IGCC power plant (output power: 342,000kW) in Japan for Nippon Petroleum Refining Co., Ltd. in the Spring of 2003. The key feature of IGCC is that it is a "power plant gentle on the environment" with a low environmental impact. Heavy metal and sulfur included in materials such as residual oil and coal are mostly separated out in the generation process of synthetic gas as fuel for the gas turbine, and thus it becomes a clean fuel equivalent to natural gas. As a result, it can reduce the sulfur oxide, nitrogen oxide and dust emissions significantly compared to the traditional power generation method. The gasification technology is also able to refine hydrogen and carbon monoxide as by-products during the gas generation process so that it can achieve total optimization of the industrial complex. For all these reasons, it has become the power plant technology that is highly respected as the next power generation technology.
