Power Generation System

In WE-NET project Phase I Program, the power generation system with more than 60%(HHV) thermal efficiency had been designed. However, because this system must be fueled by pure hydrogen, commercialization of this system in early stage is thought to be difficult. Therefore, the new project, in which the natural gas fueled system is targeted, has been started since FY1999. In this project, the power generation efficiency is aimed to be 60%(HHV) or higher, with turbine inlet maximum temperature of 1973K. In this report, the feature of the target system is explained at first. Then, the sensitivities of many parameters are examined in detail.

Abstract: Power generation using dielectric elastomer (DE) artificial muscle is attracting attention because of its light weight, low cost, and high efficiency. Since this method is a system that produces electricity without emitting carbon dioxide nor using rare earths, it would contribute to the goal of environmental sustainability. In this paper, the background of DEs, the associated high-efficient wave energy generation (WEG) systems that we developed using DEs, as well as the latest development of its material are summarized. By covering the challenges we face and the achievements that we’ve reached, we can discuss the opportunities to build the foundation of a recycled energy society through the usage of these WEGs. On the other hand, to make these possibilities commercially successful, the advantages of DEs need to be integrated with traditional technologies. To achieve this, we also consider the method of using DEs alone and a system used in combination with an oscillating water column. Finally, the current status and future of DEGs are discussed.
