The contract has been awarded by Tokyo Electric Power Company (TEPCO) for a large-scale integrated coal gasification combined-cycle (IGCC) system.
TEPCO wants to build two 500 MW IGCC plants in Fukushima and the consortium, which also includes Mitsubishi Heavy Industries, Mitsubishi Electric Corporation and Mitsubishi Heavy Industries Mechatronics Systems, has already begun design work.
One of the new plants will be at TEPCO’S Hirono power station while the other will be at the Nakoso power plant which is operated by Joban Joint Power Co, a company part-owned by TEPCO.
The plants are intended to create an industrial base and employment opportunities to provide an economic revitalization of Fukushima following the earthquake and tsunami of 2011.
MHPS said the work is also “being carried out with the added aspiration of spurring the adoption of Japan's most advanced clean coal technologies worldwide in order to resolve energy and environmental issues of global scale”.
MHPS is responsible primarily for designing the gasification and combined-cycle power generation equipment; MHI is in charge of gas refining equipment; Mitsubishi Electric will handle power generation and electrical equipment and MHI-MS will design the wastewater treatment facilities.
An IGCC system generates power using a combined-cycle format incorporating coal gasification and both gas and steam turbines. Compared to conventional coal-fired power generation systems, the IGCC configuration not only delivers enhanced generation efficiency but also significantly cuts carbon dioxide emissions.
MHPS said that “demand for IGCC systems is expected to grow in many countries like Japan that have scarce energy resources, in view of their advantages in the dual terms of effective utilization of resources and environmental protection”.
