INTERNATIONAL AND NATIONAL INITIATIVES

International Initiatives To Address The Coal Use Issues For Energy Sector ¾ UN Framework Convention on Climate Change (UNFCCC) signed at the Rio Earth Summit in 1992. Ratified by India in 1993 ¾ Kyoto Protocol introduced in 1997 and came into effect on 16TH Feb 2005 ¾ US, DOE Initiative on Carbon Sequestration Leadership Forum launched in 2003, India is member among 22 countries ¾ Asia Pacific Partnership on Clean Development and Climate in 2005, US, Australia, China, Japan, India and South Korea as partners. ¾ World’s first zero emission coal fired plant on FUTUREGEN, India joined in 2006 represented on Government Steering Committee ¾ Coal R&D programmes of other Nations include; CANMET, COAL2, EAGLE, ZECA, CCPC, CCTI

International Carbon Sequestration Leadership Forum • A unique initiative of DOE for carbon capture and storage aiming at development of improved cost-effective technologies through R&D collaborations • 16 Countries joined to form CSLF, at present 22 Countries are member of CSLF and participate in CSLF activities • The programme is well structured into Policy Group and Technical Groups. India is represented as Vice- Chair to Technical Group • Several Task Forces are constituted for assessing the Technology

• 19 collaborative research projects recognized worldwide, India participating in one CSLF project

Technology Perspectives For Carbon Management In India • Adoption of high efficiency in thermal power generation through fuel and boiler technology • Increasing use of renewable energy sources • Growing nuclear power production • Energy efficiency in end use sectors • Promotion of clean coal technology • Initiated Joint Activities to be implemented under JI/ AIJ mechanisms • Constituted National Clean Development Mechanism Authority for considering projects for availing carbon credits by eligible industry projects • Research initiated on carbon capture and storage

Research initiated on CO2 sequestration and Indian CO2 Sequestration Applied Research network launched for dissemination of information

KEY ISSUES FOR APPLICATION OF CLEAN COAL TECHNOLOGY

Key Technical Issues

™ Clean Coal Technology has been advancing rapidly globally to achieve goals of zero emission technology. ™ In India efforts towards clean coal technology development began almost two decades ago, has not kept pace with the developments ™ Lack of Research to address Problems of Indian Industry in Academic Sector

Key Financial Issues

ƒ Additional Cost involved To support Clean Coal Technology ƒ Key questions are Who Invest and Why Invest in clean coal technology development, is it the responsibility of coal producer or coal user? ƒ Inadequate R&D infrastructure in academic Institutions and National Laboratories

Key Policy Issues

9 Policies have been introduced from time to time. Integrated Energy Policy 2006 suggests creation of R&D fund for Energy 9 Appropriate marketing strategy needed for adoption of clean coal 9 Need for Capacity Building which is always Changing

TECHNOLOGY PERSPECTIVES

Technology Where Capabilities Exist • • • • • • • •

Preparation of Low Grade Coal Coal Washing Pulverized Fuel Electrostatic precipitator Fluidized bed combustion Fisher-Tropsch synthesis Super critical boiler Circulating fluidized bed coal combustion

Technology Where research has Begun- are in Commercial/ Demonstration Elsewhere • Ultra supercritical boiler • Pressurized pulverized coal combustion • Integrated gasification coal combustion (IGCC) • Pressurized fluidized bed coal combustion • Selective catalytic conversion (De-NOx)

Impact of Other Technology on Coal Use - Nano Scale Catalysts ™ Nanoscale catalysts open the way for numerous process innovations in the next few years to make many chemical processes more efficient and resourcesaving in coal use ™ Using a gel-based nanoscale catalyst, which improves the efficiency and reduces the cost has been tested for Coal Liquefaction and turn it into Gas. ™ Organo-metallic nanocubes as ideal storage medium for hydrogen, as source of energy in electronic devices

Key Recommendations 9 The coal quality, quantity and its utilization in power generation in an environmentally friendly manner need to be seen in an integrated manner. 9 There are technological, financial and policy issues as well as opportunities for implementation of clean coal technology to achieve Carbon sequestration in India. 9 New coal based energy generation technologies that produce higher concentration of CO2 in flue gas would facilitate carbon capture and storage 9 New breakthroughs on horizon such as Nanotechnology will impact energy costs significantly and change application scenario. Adequate thrust must be given to these.
