摘要

The economical evaluation of biogas cogeneration systems (BIOCGS) is important for the installment and spread of the systems in rural districts. This paper was intended to establish a simple calculation model of profit. As the result of evaluation, it became clear that the higher charge of electric power, the lower charge of gas oil and biogas, and the higher performance of the systems have critical limitation, respectively. To put it concretely, when a dairy farmer of 100 cows equipped with 20kW (72MJ/h)-BIOCGS, the profit index comes to 480,000 yen/kWh per one year. If the total cost of the systems is about 9.6 million yen, it can be said that the recovery of the invested capital makes possible in 15 years. The reduction of carbon dioxide of 87,000kg, which 3.Oha of the beech wood absorbs per year, can be expected using BIOCGS, too.
