With the advancement of technology and growth of population, energy consumptions are always increasing. Therefore, researchers have been exploring new ways to meet energy demand by looking at methods which are economically attractive as well as environmental friendly. It will be fruitful if electricity can be stored at times when the load demand, cost of energy production and the impact to the environment are low. The stored energy can be released into the grid during peak periods. This will then lower the level of energy production during peak periods and thus lower the emissions released into the atmosphere. In this report, general overviews of various typed of energy storage technologies are studied and a summary of comparison among the various technologies is presented. Hydrogen Energy Storage System is chosen as the focus of study in this report. The various stages and technologies of Hydrogen Energy Storage System are discussed and a summary is presented at the end of the chapter. A study of implementation of Hydrogen Energy Storage System is also carried out. The principles and also the methods to carry out the analysis are discussed in detail. Subsequently, the economical feasibility of such implementation in the context of Singapore is studied and investigated. The results of the investigation and recommendations will be presented at the end of chapter 4. A conclusion about the project is also presented based on the analysis of the implementation of Hydrogen Energy Storage System into the grid at the end of this report.
