Outline of Product / Technology (1) Function ① Ultra high efficiency (～60％～) power generation with coal ② Clean power generation with coal ③ Large to medium capacity power generation ④ Advanced power generation for the near future use

(2) Structure / System

(3) Features ① Ultra high efficiency power generation with coal which is the most abundantly reserved fuel on the earth.

Ultra high efficiency such as 60% (HHV basis) or higher is obtainable with coal. (under development) ② Environmentally friendly power generation with coal

As the plant efficiency is much higher than those of the presently available power generation technologies, CO2 emission is reduced to about two-third (2/3) contributing to the prevention of global warming. As the fuel gas is cleaned, then used for fuel cell first, then burnt in combustor for gas turbine, the exhaust gas contains almost no SOx, particulate and negligible amount of NOx, CO and hydrocarbon.

③ Versatility in application As the main power generation element is fuel cell which is static power generator by electro-chemical reaction, moving power generators such as gas turbine and steam turbine are comparatively smaller, the operation of the plant is low in noise and vibration and much less cooling water is required. Therefore it is applicable not only to central power generation but to cogeneration plant deployed near urban area. The plant is suitable for central power generation of large capacity and medium to small capacity as well.

④ The type of fuel cell shall be SOFC (Solid Oxide Fuel Cell) which is suitable for high temperature operation such as 1000°C.


(1) Energy saving As the plant efficiency is 60 % or higher while that of conventional type plant is approx. 40%, fuel consumption can be reduced by more than 30 %.

(2) CO2 Emission Reduction Compared with conventional coal-fired plant, CO2 emission can be reduced by more than 30%.

P-24 Toshiba Hydro-power generation system

Power Generation Hydroelectric plant for DPG Outline of Product / Technology

(1) Function Small-scale hydro-power generation system Hydro - eKIDSTM using renewable energy


General view of eKIDSTM (3) Features

Five kinds of the standard unit (S3/S3C, SS, S, M, and L) are available. Their outputs are 1 ～ 200kW depending on the flow rate of 0.3 ～3.5m3/s and the head drop of 2 ～15m. The feature of the standard unit is easy installation, small space and simple structure of pipe-in type. In comparison with large-scale power systems, the running cost is cheap and the service life is long. The standard unit is therefore economical when used in the long run. Although the major power system is operated by using fossil fuel, our unit is derived with renewable hydro-energy. So, the emission of [CO2]-gas is almost neglected and the consumption of resources is significantly suppressed. Moreover, our units do not need a large-scale barrage or a dam that gives a negative environmental impact. The merit of a small-scale system like this is to use various water sources: the water and sewage, the water for agricultural use, the water for industrial use, the industrial wastewater and the river maintenance and discharge. The system is useful as a dispersed power source and it can contribute to the reduction of the green house gas and also to the energy-saving.

P-25 Ocean Thermal Energy Conversion (OTEC) Power Power generation

Sea water desalination Ocean thermal energy, waste heat power generation plant

Outline of Product/Technology

(1) Function ① Power generation ② Desalination ③ Heat recovery for low temperature waste heat ④ CO2 reduction (2) Structure/System DTEC is a simultaneous power generation and desalination system using the low temperature waste heats, such as waste steam, waste gas, waste water, waste heat in the cooling system etc. Uehara cycle system is employed for power generation unit, where mixture of ammonia and water is used for working fluid, and flash evaporation desalination method is used for desalination unit. These units are efficiently combined in DTEC. (3) Features ① Simultaneous power generation and desalination using waste heat ② No use of additional heat energy, No use of fossil fuel ③ Contribution to cutting of cooling cost ④ Contribution to decease of burdens on environment

Energy Saving / CO2 Emission Reduction

(1)Technical Features DTEC generates the power and produces water simultaneously using waste heat ever discharged. This means that power generation and desalination is available without additional energy such as fossil fuel. (2)Energy Saving /CO2 Emission Reduction Energy saving : 3MW power generation by DTEC leads to energy saving of 6,000kl/y oil*1). CO2 Emission Reduction : 3000m3/d water production by DTEC leads to energy saving of 18,300kl/y oil*2). *1) Compared to the existing thermal power plant using oil with efficiency of 34.3%. *2) Compared to the existing MSF desalination system using oil as energy source.

P-26 WEC COUPLED NUMERICAL RESERVOIR SIMULATOR Power generation Geothermal Geothermal reservoir

Outline of Product/Technology (1) Function ① Evaluate geothermal reservoir potential ② Forecast the future reservoir and well performances


Computer simulation coupled three kinds of numerical simulators capable of calculating mass and energy transport from upstream (reservoirs) to downstream (turbines) has been conducted periodically to ensure an accurate forecast of the future reservoir and well performances, which has contributed to a stable power plant operation and a sustainable reservoir management.

(3) Features ① More accurate prediction by coupling three simulators (reservoir, well bore and pipeline flow) ② Changes of wellhead pressure and mass flow rate of production well can be predicted. ③ Fluid transportation and interconnection pressures at pipelines can be simulated.

Energy Saving / CO2 Emission Reduction (1) Technical Features

Geothermal energy is generally defined as heat stored within the earth. A huge energy is usually stored in the volcanic areas, where magma exists in deep underground. The geothermal power generation produces electricity by utilizing steam, which is rain–origin underground-water heated by geothermal energy and stored in an underground reservoir. The hot water, simultaneously spouted out with steam, is to be separated and to be returned into underground in order to save water resources and to protect surrounding environment

(2) Energy Saving/CO2 Emission Reduction

The 50,000kW geothermal power generation field corresponds to the oilfield of about 500,000 barrels/year production capacity with no production decrease. The amount of the CO2 emission from power plant is usually evaluated on the life-cycle assessment basis, where the total CO2 emission from the period of installation/construction of the plant to the operation period of the plant is considered. From this life-cycle evaluation view point, the amount of CO2 emission from geothermal power is extremely low 6.3 g-C/KWh.
