Although the situation of cogeneration in Japan has become quite important nowadays, the ratio of its capacity to the total power generation capacity of electric companies is about 2%, which is by far smaller than those in northern European countries. The main reason is the difference of climate. In northern European countries, they have cool climate, which results in sufficient needs for the hot water supply by cogeneration facilities. In contrast, Japanese climate has a hot and humid summer with few need for hot water supply. To disseminate cogeneration further under these circumstances, we must make much of the power generation efficiency as well as the temperature of exhaust heat and NOx reduction. This paper describes the recent efforts of increasing the thermal efficiency of gas engines commonly used in cogeneration facilities.
