EFFECTIVE OPERATION METHODS AND ENERGY CONSERVATION EFFECT OF HOUSING POLYMER ELECTROLYTE FUEL CELL CO-GENERATION SYSTEMS : Installation effect of distributed power and heat source system for housing (Part 1)

Abstract

This paper presents the effective operation methods and the regional energy conservation effects of housing Polymer Electrolyte Fuel Cell Co-Generation System (PEFC-CGS). We built the model-based simulation program to calculate the energy budget in a case that PEFC-CGS was introduced to detached houses considering specifications of a real PEFC-CGS. As a result of model-based simulations, we found that DSS (Daily Start and Stop) operation was the most effective method. Energy conservation effect is higher in cold areas because it varies by quantity of hot water supply load. The primary energy consumptions are reduced by 4-13% and CO_2 emissions are reduced by 7-20% in Japan. These values are increased by 1-2% in a case of the reverse power flow. Utility costs are also reduced by PEFC-CGS, but they vary by payment setting in each area.
