Beginning the World's First Integrated Coal Gasification Fuel Cell
Combined Cycle (IGFC) Demonstration Project- Aiming to Both Improve Efficiency of Coal-Fired Power Generation
and Greatly Cut CO2 Emissions NEDO and the OSAKI CoolGen Corporation began work on the third step of theOsaki CoolGen Project, namely, the demonstration project of IGFC with CO2 capture,
which combines fuel cell technology with integrated coal gasification combinedcycle (IGCC) with CO2 capture.
In the recently-begun third step, we will combine a fuel cell with the oxygen-blown
IGCC demonstration facility with CO2 capture, to be constructed in the second stepscheduled for completion in FY2019, as well as confirm the applicability of coal
syngas for fuel cells, and then perform demonstrations aimed at achieving an
optimal IGFC system with CO2 capture. We aim to see a prospect of achieving a net
thermal efficiency (HHV) of approximately 47% while capturing 90% of the CO2 on a
500 MW-class commercial unit.
Moving forward, we aim to establish technology that achieves both highly-efficientcoal-fired power generation and CO2 separation and capture and spread thattechnology both inside and outside of Japan, thus contributing to the global CO2
emissions control (global warming countermeasures).

Coal has a high supply stability and outstanding economy, making it a vital primary source ofenergy to Japan, which has an extremely low energy self-sufficiency rate. Coal-fired power
generation is an important energy source covering approximately 30% of generated power.
On the other hand, compared to other fossil fuels, coal also has issues, such as its large amount ofcarbon dioxide (CO2) emissions and in terms of the global environment. Coal-fired power
generation faces demand for further restraints on CO2 emissions.
Therefore, the New Energy and Industrial Technology Development Organization (NEDO) and theOSAKI CoolGen Corporation are engaged in the Osaki CoolGen Project, which aims to achieve
revolutionary low carbon coal-fired power generation through the combination of integrated coalgasification fuel cell combined cycle (IGFC) technology, the ultimate high-efficiency generating
technology, with CO2 capture technology, in order to greatly reduce CO2 emissions from coal-firedpower generation.
The IGFC demonstration project comprises of oxygen-blown IGCC demonstration (first step),oxygen-blown IGCC with CO2 capture (second step), and IGFC with CO2 capture demonstration(third step), and uses a 170,000 kW-class demonstration test facility constructed within thegrounds of the Osaki Power Station of The Chugoku Electric Power Co., Inc. to verify theperformance, operability, reliability, and economy of the system. In the demonstration tests for thefirst step, which began in March of 2017, we achieved a net thermal efficiency of 40.8% (HHV), thehighest level of efficiency in the world for a 170,000 kW-class demonstration plant, and saw aprospect of achieving a net thermal efficiency of approximately 46% on a 500 MW-classcommercial plant. For the demonstration in the second step, we are currently proceeding withconstruction work on the CO2 capture unit and we plan to begin test operation around the summerof 2019, then start demonstration tests after that.
Now, we began work on the demonstration project for IGFC with CO2 capture. We will add a fuelcell to the oxygen-blown IGCC with CO2 capture in order to confirm the applicability of coal syngas
for fuel cells, performing demonstrations aiming at achieving an optimal IGFC with CO2 capturesystem. We aim to obtain a prospect of achieving a net thermal efficiency (HHV) of approximately
47% while capturing 90% of the CO2 when applied to a 500 MW-class commercial unit.
