Starting demonstration tests for oxygen-blown integrated
coal gasification combined cycle technology
with CO2 capture- Aiming to achieve a 90% capture rate of CO2 and a net thermal
efficiency of 40% at commercial power plants NEDO and the OSAKI CoolGen Corporation are engaged in a demonstration projectthat consists of three steps to verify a revolutionary low carbon coal-fired power
generation technology, through the combination of integrated coal gasification fuelcell combined cycle (IGFC) technology with CO2 capture. The second step of thisproject, which is to verify oxygen-blown integrated coal gasification combined
cycle technology with CO2 capture (oxygen-blown IGCC with CO2 capture), began
on December 25.
Through these demonstration tests, we aim to obtain a prospect of achieving a net
thermal efficiency of 40% (Higher Heating Value based)*HHV, equivalent to thelatestrecent pulverized coal-fired power plant, while capturing 90% CO2 at acommercial power plant (1,500C-class IGCC), which will enable us to verify thebasic performance, plant operability, reliability, economic feasibility, and otheraspects of the oxygen-blown IGCC with CO2 capture. By making the best use of theprospects which we obtain through the demonstration, we aim to establish anoxygen-blown IGCC with CO2 capture and spread the technologies to worldwide.
This will lead us to contributing to the global CO2 emission reduction (globalwarming countermeasures).

1. Overview
The New Energy and Industrial Technology Development Organization (NEDO) and the OSAKI
CoolGen Corporation are engaged in the "Integrated Coal Gasification Fuel Cell Combined Cycle(IGFC) Demonstration Project", which aims to achieve revolutionary low carbon coal-fired power
generation through the combination of integrated coal gasification fuel cell combined cycle (IGFC),
the ultimate high-efficiency generation, with CO2 capture, in order to greatly reduce carbon dioxide(CO2) emissions during coal-fired power generation.
This demonstration project consists of a demonstration of oxygen-blown integrated coalgasification combined cycle technology (oxygen-blown IGCC) in the first step , a demonstrationof oxygen-blown IGCC with CO2 capture in the second step, and a demonstration of IGFC with
CO2 capture in the third step. It puts into use a demonstration test facility constructed within thesite of the Osaki Power Station of The Chugoku Electric Power Co., Inc. to verify the basic
performance, plant operability, reliability, and economic feasibility of the system. Through the firststep of the demonstration, which began in March of 2017, we achieved a net thermal efficiency of40.8% (HHV), the highest level of efficiency in the world for a 170 MW class coal fired plant, andsaw a prospect of achieving a net thermal efficiency of approximately 46% (HHV) by applying
these results to a commercial power plant (1,500C -class IGCC) with the new technology
implemented.
We have recently completed the construction of the CO2 capture facility and began the second
step on December 25. In the second step, we are going to verify the basic performance, plant
operability, reliability, and economic feasibility of the oxygen-blown IGCC with CO2 capture,through a combination of the oxygen-blown IGCC demonstration test facility with the CO2 capture
unit. Regarding the issue of reduced generating efficiency due to the energy loss that occurs
during CO2 capture, we aim to obtain a prospect of achieving a net thermal efficiency of 40%(HHV), equivalent to the recent pulverized coal-fired power plants, while capturing 90% CO2 at thecommercial IGCC gasification process.

capture processes at oxygen-blown IGCC plants equipped withdemonstration facilities for CO2 capture.

(2) Implementation period: From December 25, 2019 to February 28, 2021

(3) Implementation location: Within the site of the Osaki Power Station of The Chugoku ElectricPower Co., Inc. (6208-1 Nakano, Osakikamijima-cho, Toyota-gun,Hiroshima Prefecture)(4) Demonstration test targets : See the table below.

Target/Indicator

Basic Performance

To obtain a forecast of a power generation efficiency of approximately 40%(net HHV)(Power generation

while capturing 90% of the CO2 in the newly-built commercial IGCC plant(1,500℃efficiency)class IGCC)

Basic performance(CO2 recovery rate andCO2 recovery rate : 90% or more / Captured CO2 purity : 99% or morepurity)
Plant Operability andreliability

EconomyTo establish the operational method of IGCC with CO2 capture and to verify thereliability

To evaluate the cost per amount of recovered CO2 in the commercial IGCC plantusing cost target data shown in the Technology Roadmap as a benchmark.

By achieving the targets set for these demonstration tests,we can create a coal-fired power
generation system with virtually no CO2 emissions by incorporating new CO2 utilization andstorage technologies that are currently being developed as part of other projects.

3. Future Plans
During the third step (FY 2018 to 2022), we plan to implement a demonstration test for IGFC with
CO2 capture by integrating fuel cells with the demonstration facilities used in the current tests. We
aim to obtain a prospect of achieving a net thermal efficiency of approximately 47% (HHV) while
capturing 90% CO2 at the 500MW class commercial IGFC.
