Fossil Fuel – Main Stay of Energy

 World Energy demand – 82% in 2030, 64% in 2050
 World Coal Demand - +60+ from 2006 to 2030
 Reserve Energy Resource – 144 Years Equitable distribution of fuel reserve and energy security
 Emission reduction potential : 1.8-2.5 Gt/yr by applying BAT to fossil
power2IEEJ：December 2015, All Rights Reserved.

Key Technologies and Best practices

 Supercritical and ultra Supercritical technologies
 Integrated Coal Gasification Combined Cycle (IGCC)
 Advanced Ultra Supercritical Technology
 Renovation and Modernization Technologies for existing power station
 Waste Heat Recovery from the power plants
 Development and Deployment of other innovative high efficiency cycles
Ex: Ammonia and Organic Rankine Cycle
Average efficiency in coal-fired power plants in MEF countries from 31%
to 42%3

Barriers

 Insufficient information
 Varying qualities of coal High upfront cost of advanced high efficiency and lower emissions coaltechnologies
 Lack of appropriate price/financial/regulatory incentives (domestic andinternational)
 Inadequate Operation and Maintenance (O&M) skill
 Insufficient R&D efforts

Actions and Recommendations5

 Identification and information sharing of Nest Available Technology (BAT) options and Best
Practices (BP) Nationally Appropriate Technology Deployment roadmaps

 Appropriate price/financial/regulatory incentives for the uptake of BAT and BP Cooperation with private sectors

 Technology transfer mechanism enabling effective matching between technology owners andfinancial sources

 Capacity building efforts (domestic and international initiative) Technology R&D roadmaps (domestic and international sharing) Enhancement of R&D efforts and international R&D collaboration including public and private
partnership (Ex: nationally appropriated R&D goals, demonstration projects in overseas) Identification and utilization of on-going international initiatives (Ex: APP, IEA ImplementingAgreement)

 Information sharing with other MEF initiatives
