MHI,Toho Gas Jointly Develop Gas Cogeneration system

Mitsubishi Heavy Industries and Toho Gas Jointly Develop New 450kW Gas Cogeneration System Offering World's Highest Efficiency Level (42.0%) in its Class

Tokyo, March 18, 2015 - Mitsubishi Heavy Industries, Ltd. (MHI) and Toho Gas Co., Ltd. have jointly developed a new 450-kilowatt (kW) gas cogeneration system. The new product will be launched into the Japanese market by both companies on April 1.

The newly developed gas cogeneration system, which is based on a previously introduced 380kW system, achieves an outstanding power output of 450kW, made possible primarily through optimization of combustion and the adoption of components enabling superior efficiency. Generating efficiency is 42.0%, the world's highest level in the 400kW class, and overall efficiency is a robust 81.5%.1

In addition to these achievements in power output and generating efficiency, increased merits in terms of both initial costs and running costs were pursued through the elimination of the need for denitrification equipment; together these benefits enable a faster investment return than with the 380kW system. A 20% reduction in installation space requirements has also been achieved by trimming the physical dimensions of the main unit.

In the wake of the Great East Japan Earthquake, customer interest in gas cogeneration systems has strengthened not only because of their extremely efficient use of energy but also for their contributions to achieving power security and saving power in line with business continuity plans (BCP). Customers are also showing greater interest in achieving higher performance levels.

Going forward, MHI and Toho Gas intend to propose the new 450kW gas cogeneration system for adoption in hospitals, commercial facilities, office buildings, factories, etc. as a way of promoting the further adoption of these efficient systems, while simultaneously making positive contributions to saving energy and easing burdens on the environment.
