5 Available feedstock of TIGAR Easy utilization of Coal and Biomass feedstock because of operating under atmospheric pressure Simple feeding system to gasifier Wood Available Feedstock Easy CO2 Reduction Bagasse Coal (LRC) Bark Palm Waste 5

6 Steam gasification of lignite Lignite can be easily gasified. Carbon conversion [mol/mol] Lignite Bituminous Sub-bituminous Gasification time [min.] Lignite steam gasification is faster than bituminous coal Steam gasification is suitable for lignite Steam gasification in lab. fluidized bed reactor (0.1MPa, 900degC) 6

14 Future plan Indonesia energy aspect Indonesia has big amount of resources of Row Lank Coal. Indonesia has also big amount of resources of Natural gas. The demand for Natural Gas is in particular big by the fertilizer industry. Coal Natural Gas 4% (310) 6% (464) 4% (306) 0.5% 2% (90) 1.1% (150) (39) Policy of Indonesia energy supply Sub bituminous 26.7% Anthracite 0.3% Lignite Bituminous 58.7% 14.3% Indonesia Coal Resources Fertilizer 7% (562) 11% (884) 11% (914) 5% (443) 49% (3935) Export Natural gas Total:8,095.5MMSCF consumption in Indonesia (2006,MMSCFD) For Indonesia, gasification of LRC as the backup of Natural Gas is required. For Japan also, gasification of LRC contributes to energy security. 14

16 Summary Twin IHI Gasifier (TIGAR ) is being developed for lignite gasification. TIGAR can stably produce syngas with higher heating value from Lignite coal. 6t/d Pilot Plant test indicated that TIGAR system is proven technology for lignite gasification. CO2 can be captured from syngas using coal gasification, and TIGAR can utilize the biomass as feed stock easily, so can suppress the production of the CO2. We are planning to apply TIGAR to Indonesian fertilizer plant as the first step of the commercial stage. 16
