Energy Saving Performance of Detached House with Hydrogen Co-generation System

摘要

Energy consumption is increasing every year in building sector, utilization and development of alternative energy sources and technologies to support the requirements of every house. The hydrogen fuel cell is one of the latest technologies for distributed energy systems. This research is aim to grasp the energy saving performance of the hydrogen co-generation system in the detached house. First, it investigated on the demand-side energy consumption including electricity, cooling, heating and hot water. Second, it introduced a distributed energy resources (DER) system and set six cases to analyze the energy utilization. Different options for changing the heating, cooling, electricity and hot water systems were compared for this type of detached house, assuming basiccase as a reference. Changes in the fuel used, energy operation machines and also demand side and supply side were analyzed. Except past case, every case will be operated under the electricitytracking mode and heat-tracking mode. The comparisons and evaluations of the energy consumption between cases can suggest the environmental performance of the hydrogen co-generation system.
