seminar report on hydrogen based utility energy system
Abstract
The most serious defects of a wind turbine system are instability of the output and power transmission problem. This report aims at a stand-alone wind turbine system with a hydrogen generator (wind power - hydrogen energy system). In comparison with electric, hydrogen is suitable for energy storage and transport. So this system improves fluctuating output power of the wind turbine generator and the energy transmission problem occurred by converting electric to hydrogen. Firstly, the I-V characteristic of a small-scale wind turbine generator was analyzed to investigate how the wind turbine generator operates under the influence of connecting with the hydrogen generator directly. As a result, it has been turned out that the system was not matching at all. Therefore, it is necessity to install controlling devices between the wind turbine generator and the hydrogen generator. Based on the result, we considered that the energy capacitor system (ECaSS) would have good performance in wind power - hydrogen energy system. Then, we assembled the wind power-hydrogen energy system with ECaSS actually, and evaluated the utility.
Introduction
The quality of life in society is directly linked to the access to energy. To achieve a high standard of living, the energy supply must be safe, reliable and affordable for everybody. Moreover, the energy supplied to customers should be usable for various applications. This suggests electrical energy which can be easily transformed to all the needs of the customer: power; heat; light; and communication. Therefore the trend to increase the utilisation of electricity in customer applications will continue in the future. Electrical energy, however suffers from some disadvantages: transportation is only possible over limited distances and needs a network; also direct storage systems for large capacity systems are mainly in the prototype and demonstration phases of development. The introduction of hydrogen will help to overcome these difficulties as it can be easily produced by electrical energy via electrolysis and reconverted to electricity by power plants. This article describes various activities being carried out by certain German utilities in conjunction with other European and Canadian utilities in preparing the way for the introduction of integrated hydrogen energy carrier systems within traditional fuel based energy infrastructures.
