Türkiye'de Müstakil Bir Konut İçin Kurşun-Asit Pil Destekli Yakıt Pilinin Tekno-Ekonomik Analizi

Abstract

The penetration rate of renewable energy sources is increasing day by day. However, most depend on the weather conditions such as solar, wind, precipitation, etc. This dependency also creates reliability problems for stand-alone systems. Fuel cells are essential solutions to overcome these issues since they need hydrogen to produce electrical energy, one renewable energy source that does not depend on weather conditions. In this research, an end-user profile, isolated from the grid and provides its energy by using a battery-backed PEM fuel cell, has been technically investigated in the simulation environment within the scope of the scenarios created. So, the systems intended to be implemented in reality have been transferred to the simulation environment. During the operation, to prevent deep discharge and overcharge of the battery pack, the fuel cell is kept in operation between a minimum of 40% and a maximum 90% State of Charge (SoC). Based on this system, initial investment, operation, and maintenance costs for a battery-backed fuel cell supply system are calculated and presented. The battery-supported fuel cell system is 46% expensive for lower consumption cases and 63% more expensive for higher consumption cases than grid prices.
