1 India-Japan Industry & Energy Seminar Clean Air India ; Technological Options and Emission Improvement Introduction of technologies for reducing air polluting materials from power generation sector May, 2018 Noboru AOKI Director General, Environment Department New Energy Development and Industry Development Organization (NEDO)

2 Position of Coal-Fired Power in the Future According to IEA outlook, coal fired power generation will play one of the major role in the future, especially in coal-rich countries. Future power capacity by resources TWh Renewables Nuclear Oil Gas Coal Source:World Energy Outlook

3 Air Pollutants from power sector According to IEA special report, air pollution is the fourth greatest overall risk factor for human health worldwide. Power generation is a major source of worldwide SO x emissions (one-third of the global total) and NO x (14% of total NO x ). Coal fired power generation is the chief fuel responsible for air pollution in the power sector, accounting for three-quarters of the sector s SO 2 emissions, 70% of its NO X.

4 Environmental Technologies Japanese coal-fired power plants are superior in terms of environmental friendly. Japan s SO x and NO x emission level per electric power is very lower than US and EU countries. Japan can provide state of the art technology to minimize environmental impact. International Comparison of SO x and NO x emission level per electric power (2015) (g/kwh) Sulfur Oxide (Sox) Nitrogen Oxide (Nox) USA Germany France Japan Source:OECD StatExtracts, IEA Energy Balances 2017, The Federation of Electric Power Companies of Japan 3

5 The atmosphere situation of Kawasaki-city Air condition has been drastically improved in Japan because of our continuous efforts for R&D and introduction of more environmental friendly technologies. Our technologies could be a resolution of air pollution in other countries. (1960 s) (2015 s) 4

6 Diagnostic Study for Environmental Measures Site study period: February 2018 Team composition: JCOAL, Kyuden International <Dadri Thermal Power Station, NTPC> 1820MW -Stage I: 210MWx4(COD ) -Stage II: 490MWx2(COD 2010) Located in UP, supplying electricity to Delhi NCR Delhi Dadri <Summary of the interim proposal> In view of the relevant requirements and technical feasibility by considering cost and space, a case with four units of FGD was determined as the highest priority. <Progress of the Study> Interim reporting was completed at the plant, NTPC as well as CEA immediately after the site study. The outcome of the analytical work and the final proposal in the Final Report are to be provided. BOILER <<DRY >> ESP ESP IDF BUF (FGD BYPASS LINE) <<WET> > FGD DRY STACK WET STACK 5

7 Utilization of Biomass / CFB Boiler Technology1 Technology CFB can utilize wide range fuels by following features : A) Long combustion time by the circulating => Easy to burn unreactive fuels like Anthracite B) Large heat Capacity in Furnace => Easy to burn High moisture fuels like Biomass C) Controlled combustion temperature => Low and Controlled Emission (SO x and NO x ) Long Burning Time By Circulating combustion Gas temp o C Cyclone Gas velocity around 5.0 m/s Biomass < 50 mm Coal <10 mm Furnace Low emissions DeSOx by limestone Low NOx by Low Temp. Limestone <1 mm Wallseal Windbox Combustion air Fuel Flexibility with large heat capacity fluidizing bed 6

8 Utilization of Biomass / CFB Boiler Technology2 CO2 Reduction Solution in Small Capacity Unit for Indonesia Biomass co-firing technology with Coal realizes CO2 reduction for small to middle size subcritical power plants. Energy security for varieties of coals including high moisture low rank coals, Waste to energy for waste tire (TDF), plastic refused fuels etc. are used even in a boiler. This solution can be suitable for Indonesia which is trying to commit drastic CO2 reduction and to develop middle size project. Fuel Combustion Test Coal Gricidia (Plant) Realizing USC level or less CO2 emission by Biomass and Coal Co-Combustion Testing Facility Palm Karnel Shell Corn Cob Testing with actual fuels in Indonesia by own pilot facility in Japan SUMITOMO HEAVY INDUSTRIES, LTD (SHI)has developed Co-Combustion technology and already delivers over 50 units of those kinds of fuels boilers since 2002 and has a high reliable operation records in Japan and east Asia for the industrial facility and IPP use. 7

9 Utilization of Biomass / Gasification technology3 Japan has developed an advanced gasification technology producing fertilizer materials(ammonia and urea) from low rank coal and biomass by NEDO Project. Using lignite and biomass effectively could contribute to utilization of agricultural residues and mitigation of air pollution in India.

11 5.Summary Coal fired power generation will continue to play one of the major roles in the future, but Environmental Technologies are required for existing power plants for minimizing air pollution. Japan has a lot of experience to use Environmental Technologies (for NO x, SO x, and PM) for coal fired power plants, and also has developed biomass co-firing technology and gasification technology for utilizing biomass and lignite. Our advanced Environmental Technologies including biomass utilization technology could be a resolution to mitigate the air pollution issues in India. NEDO is making efforts to disseminate Environmental Technologies to India power sector through diagnosis activities under CEA-JCOAL cooperation. 10
