Member State Perspectives

Principles of Policy and Positioning of Coal in the “Basic Energy Plan”

The Cabinet Council decided a new “Strategic Energy Plan” on April 11, 2014. Coal is reappraised as a base load fuel Enhancement of environmental compliance in coal

Clean Coal Technology

(1) Principles of the Energy Policy

“3E + S”

Stable supply (Energy security)

Cost reduction (Economic Efficiency)

Environment

Safety

・Important energy source for the base load power supply・Development of high efficiency technology (such as IGCC, etc)

(2) Position of Coal(2) Position of Coal

CURRENT COAL SITUATION

2014 Policy Dialogue on Energy for Sustainable Development for Asia and the Pacific26-28 November, 2014 | Bangkok

○Stabilization of energy demand / supply balance.

○Development promotion and overseas deployment of clean coal technologies

・G to G policy dialogues・Government supported programs,

investment/liability assurance, ODA, yen loan, etc. by JBIC, NEXI

【Policy tools】

◆ Promotion of coal utilization technologies◆ Ensuring sustainable supply of coal resources

＜Acquisition of interests＞＜Enhancement of relationships with coal producing

countries＞＜Moderation of coal demand/supply through

utilization of low rank coal＞

＜Efficiency improvement, CO2 reduction, utilization of low rank coal, etc. ＞

＜Contribution to CO2 reduction overseas through overseas deployment of clean coal technologies＞

Coal Policy

Coal will continue to be important part of energy source diversification in Japan.

AREAS FOR COOPERATION• Coal should be used as a main fuel in the

future. Non-OECD countries will use muchmore coal than OECD countries in the future.

• However, consideration should be paid toreduce air pollution and GHG emission inorder to continue using coals.

• Now, Promotion of Clean Coal Technology isessential.

• Japan develops promotion and overseasdeployment of clean coal technologiesintroduced here.


Thank you.
