13 CCT International Corporation Utilization of CCT in Australia/Asia Japanese technological support; participation in CCT projects Effective application of coal and advanced technology development in Japan 12 Japanese CCT High-efficiency -fired Power Technologies (USC/IGCC) Reduction gasification Purification/fuel synthesis Reduction Environmental technologies (flue gas and coal ash handling, CCS, etc.) Synthetic fuel(dme/sng etc) from Low Rank Low Carbon Fuel with CCS CCTin coal mine Australia (ZeroGen, Brown ) Indonesia (LCR) China (LCS,Power Plant Business) India USA/Canada EU etc

14 Obstacles for CCT Export Limited Domestic Market for CCT Limited Business Opportunity for Japanese Company to demonstrate/commercialize CCT In OECD Countries where the coal is primary source of energy, the Government support as much as Approx. 2,000Billion US$ in total has been announced to be used for developing demonstration and/or commercialization of CCT in its own country. In Non-OECD Countries, the investment priority is higher for the infrastructure development and the priority of expensive CCT project is low. 2. Huge Capital Investment Limitation of Investment by Private Only Fund for Feasibility Study/FEED: Huge engineering cost (say 10 MUS$) has to be spent before a due diligence for investment decision is made Plant Construction Cost: Total Capital Investment will be Billions of US$ and with high CCS risk 3. Who will bear CCS Risks? (CCS Policy, Legal System, restriction etc. is not clear) Commercial Gap with other energy (needs Feed-in-Tariff/Government Support) CCS related restrictions, What, When, How? (Cap&Trade, Carbon Tax?)

15 Government Support Expected Japanese Government s Support To support creating demonstration/commercialization of CCT Project in foreign County Positive action to jointly develop a project in line with the need of counter part country. OECD Country: to establish the system which can comprehensively perform joint project development in cooperation with the support provided by the counter part country. (Example: Australia ZeroGen IGCC+CCS Project, US Gasification Projects) Non-OECD Country: With due considerations to the needs of Counter Part Country, the system which can take a lead to jointly develop a project should be established. 2. Support Development Cost before investment decision is made To establish the system (Fund) for support a partial cost of FS & FEED (in Non-OECD Country) or to support full cost of FS & FEED (in OECD Country) 3. To establish the system (Fund) for Equity Participation and/or provide financing Equity: to cover bigger risk than private investor (Example: inferior return, in case of project No Go, can be treated as Grant ) Finance: concessional terms which can not be expected from private market. (Example of US Case: Coverage : 80% of Capital, Period: Years, Interest Rate: 0.25%+Treasury Bond) 4. To establish the system (Fund) for supporting Japanese Contractor s fee for M&A/Joint Venture etc which will be required for securing technology priority/cost competiveness Expected Support from Counter Part Country 1. Acknowledging Commercial Gap of CCT to the other energy, the support for CCT Project by risk sharing, such as Product Off-Take Guarantee, Off-Take Guarantee, Feed-in- Tariff, Tax Incentive, to be provided. 2. To establish the system which enable CCT project through International Collaboration with Japanese Government. ( establishment of a new organization which can coordinate all the opinion of different Ministries, Agency etc. including new policy, framework, legal system modification etc.)

16 Summary 15 reduction in Power Plants is one of Key factor for Low Carbon Society. Introduction of IGCC Commercial plant following USC and the preparation for CCS High Efficiency of Thermal Power Plant (USC,IGCC) CCS (Pre Combustion, Post Combustion) Low Carbon Fuel for Power Plant from Low Rank (DME SNG) IGCC & CCS is key factor of CCT, however,project cost is huge and the risk of CCS is uncertain, Government s financial support is vital for commercialization of Japanese CCT all over the world (All stage of FS/FEED/EPC construction) Cooperation and supports by both governments are required for the utilization of CCT in overseas.
