MHPS receives IGCC orders

World Coal,

A consortium led by Mitsubishi Hitachi Power Systems Ltd (MHPS) has received successive full-turnkey orders for integrated coal gasification combined-cycle (IGCC) plant facilities from Nakoso IGCC Power GK and Hirono IGCC Power GK. Both plants will have a generating capacity of 540 MW with operations expected to commence in September 2020 and September 2021, respectively.

In the case of Nakoso IGCC Power GK, the new plant will be located on property adjacent to Joban Joint Power Co. Ltd's Nakoso Power Station in Iwaki City. The plant on order from Hirono IGCC Power GK will be built on the site of TEPCO Fuel & Power Inc.'s Hirono Thermal Power Station in Fukushima's Futaba District. The IGCC project is intended to contribute to the revitalisation in Fukushima Prefecture and the development of industrial infrastructure and economic recovery in the area.

The IGCC facilities on order are power generating plants based entirely on technologies developed in Japan. In an IGCC system, coal is gasified in a high-temperature, high-pressure gasification furnace, and power is generated using a high-efficiency combined-cycle format integrating gas and steam turbines. The system is revolutionary in that power generation efficiency is significantly higher than in conventional coal-fired thermal plants, and CO2 emissions are 15% lower. In addition, IGCC systems are better suited to the use of low-grade coal compared with earlier coal-fired plants, assuring optimal environmental protection. This is an advantage for efficient use of resources, especially in countries like Japan which lack abundant commodities. For these reasons, demand for IGCC plants is expected to grow in the years ahead.

MHPS is to work closely with its three partners in the consortium: Mitsubishi Heavy Industries Ltd (MHI), Mitsubishi Electric Corp., and Mitsubishi Hitachi Power Systems Environmental Solutions Ltd. In the process, every effort will be made to further improve IGCC technologies to enable even more efficient use of resources and further protect the environment.
