Abstract

Abstract: Firstly, the technical principle of Japan household fuel cell CHP system (ENE-FARM) and its application are introduced. Secondly, in view of the complex characteristics of the factors that affect the economics of ENE-FARM, a general economic analysis model of ENE-FARM is established that takes into account equipment prices, annual household electricity consumption, electricity and gas prices and other factors. Thirdly, the break-even electricity price curve is used to analyze the economic differences of ENE-FARM applied in Japan and China, and a scenario analysis is made respectively for both 2020 and 2030. The results show that at present, ENE-FARM has the application economy in Japan, but has no conditions for large-scale promotion and application in China. It can be applied in remote areas such as islands and other disaster-prone areas. In 2030, with the gradual decrease of the equipment cost and perfection of residential electricity and gas price system, the application of the ENE-FARM system in domestic households will achieve a break-even.

Key words: fuel cell, combined heat and power system, economic efficiency, break-even electricity price curve, scenario analysis
