Current status of coal gasification 185

purpose was the development of a coal gasification fuel cell system for power gener-
ation or production of synthetic fuel, hydrogen, and chemicals utilizing the HYCOL
technology (Guan, 2017; NEDO, 2007).
Based on these achievements, a demonstration plant (Fig. 7.3) is being built under
the Osaki CoolGen Project by the Osaki CoolGen Corporation. This project is subsi-
dized by New Energy and Industrial Technology Development Organization (NEDO).
The project is being implemented as an “integrated coal gasification fuel cell com-
bined cycle (IGFC) demonstration project” with a coal processing capacity of
1180 tones/day and an output of 166 MW. It includes a test facility for oxygen-
blown IGCC constructed inside the grounds of Chugoku Electric’s Osaki Power Sta-
tion, CO 2 capture, and combination with fuel cells (Osaki CoolGen Corporation, n.d.;
Yamauchi, 2017). The last news received of this project report that, following the
schedule established, the demonstration test of the first stage of the project has been
launched in March 2017, and it is expected to be in commercial operation in 2019
(Osaki CoolGen Corporation, 2017).

7.2.1.2.2 Nakoso air/oxygen-blown IGCC
Nakoso 250 MW IGCC Plant is the first and successfully commercial IGCC system
developed by Japan. With a capacity of 1700 tons/day, the facility is based on the
Nakoso PP-type gasifier (dry coal-fed, air-blown, pressurized two-stage, entrained
beds). More information is provided elsewhere (Guan, 2017; NEDO, 2007; Yamauchi,
