摘要
近年来,由于具有较高的能源利用效率和较低的温室气体排放量,燃料电池在住宅中的应用在日本受到了关注.另外,太阳能电池系统也早已被导入住宅的能源利用中.然而,住宅用燃料电池和太阳能电池系统的初始投资成为这类住宅能源系统普及应用的一个主要的障碍.在人类的生产活动中,新的产品会随着技术的提高、产量的增加而降低成本,这两种系统的初始投资也必将降低.但是很少有研究涉及到考虑初始投资递减的这类系统的经济性评价.文中通过应用学习曲线的方法,预测了2005～2030年间以5年为间隔的日本住宅用燃料电池和太阳能发电的初始投资递减,并且试算了日本典型住宅的通用能源系统、燃料电池系统和太阳能电池系统的年间能源费用,由此评价了住宅用燃料电池和太阳能发电的经济性.
In recent years, the application of the fuel cell cogeneration systems in residential houses has begun to draw interest in Japan due to their high energy efficiency and low carbon-dioxide emissions. Photovoltaic system also has gradually been introduced in the residential houses. However, their high initial costs are disadvantageous to the promotion of these systems in residential sector. On the other hand, the initial cost will decrease with the technological progress and the expansion of production. Few of researches addressed the economic effect of these systems considering the initial cost redemption. In this paper, by using the learning curve methodology, the initial cost redemption of these systems from 2005 to 2030 is predicted at an interval of 5 years. The annual operation of conventional system （normal household energy system in Japan） , fuel cell cogeneration system and photovoltaic system are simulated in a typical Japanese detached house and the corresponding annual running costs are evaluated. Based on these initial cost prediction and simulation results, the economic effect is examined from 2005 to 2030.
