Introduction of Co-generation System to Motor Parts Factory
- Representative Participant
- DENSO CORPORATION
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
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
