Study of Hot Spring-Power Generation Systems in Fukushima（１）

Abstract

There are a lot of hot springs in Fukushima. The thermal energy of the hot spring is a valuable energy resource. In this paper effectiveness as the heat source for power generation systems is investigated. The temperature of 70 ℃ or more and enough flowrate are necessary as the heat source for power generation systems of 10kW class. However there are few regions where this condition is satisfied in Fukushima. Because the potential heat of the hot spring water in Fukushima is not low, it is proposed to use the hot spring water as the heat source of power generation systems by compensating for shortfall energy.
