Mitsubishi Fuso Truck and Bus Corporation (MFTBC) has installed a gas engine cogeneration system at its Kawasaki Plant. A cogeneration system is one that generates more than two types of secondary energy from primary energy continually and concurrently. It uses exhaust heat at the time of power generation in generating vapour to be supplied to the production lines, making more efficient use of energy possible.

MFTBC replaced a 20-year-old gas turbine-based cogeneration system with the new engine-based system, and simultaneously revamped the air conditioning system for several buildings in the plant to feed centrally from the new gas engine.

By using the newly deployed gas engine capable of producing 5750 kW of electricity, approximately half the plant‘s power demand can be covered. A hot-and-chilled-water network is used to cool and heat offices and production facilities across the Kawasaki Plant. This allows MFTBC to boost energy efficiency and reduce CO2 emissions.
