Outline of GHG Mitigation Activity

By introducing co-generation system (gas engine 7,800KW + Absorption Chiller 700RT) in the Motor Parts Factory at the Thailand,

we aim following contribution.

(1) Contribution in the environmental aspect

     (Promotion of Energy saving , CO2 reduction) (2) Contribution in the social aspect

     (Stable supply by distributed power supply)

(3) Contribution in the technical aspect

     (Acquisition of maintenance skill by local staff)

(4) Contribution in the economic aspect

    (Influence of business model of on-site co-generation system)

About “(1) Contribution in the environmental aspect”, we can operate co-generation system by high energy efficiency from following

reasons, and greatly contribute to energy saving and CO2 reduction.

(see right figure)

*1 Suppress of power supply loss by on site generator.

*2 Adoption of the high efficiency gas engine of the Japan

     manufactured by world’s best level

   *3 Effective utilization of all waste heat for air-conditioning of plant.

Expected GHG Emission Reductions

5,904 tCO2/year

CO2 reduction of this project

   = A : CO2 reduction of electricity + B : CO2 reduction of Natural gas


A : CO2 reduction of electricity

= (Reference usage – Project usage) × Emission electricity coefficient

= (electricity generated + electricity reduction of turbo chiller and once-through

     boiler as reference by using exhaust heat from co-generation system) ×

     Emission electricity coefficient

B : CO2 reduction of Natural gas

= (Reference usage – Project usage) × Emission Natural gas coefficient

= (natural gas reduction of once-through boiler as reference by using exhaust

     heat from co-generation system - Natural gas consumption in co-generation

     system) × Emission Natural gas coefficient
