Analysis of Production and Storage of Secondary Energy Derived from Renewable Energy

Abstract

This paper aims to study how secondary energy should be towards 2050 and beyond where renewable energy plays a major role as energy sources. First, the paper investigates the time distribution of surplus power in various scenarios using a power supply and demand analysis model. Next, this paper conducts the economic analysis including capital and operation costs, assuming the capital investment and operation of hydrogen production and storage equipment. The result indicates it is highly possible under certain circumstances in the future, where renewable energy power generation expands that, coexisting with and complementing power storage technology, new forms of energy system based on the production, storage, and use of secondary energy such as hydrogen will be established in an economically feasible manner.
