|Title:||Safety assessment of using hydrogen as clean fuel for domestic applications||en_US|
|Abstract:||Using hydrogen gas as fuel is very important in terms of environmental protection. Hydrogen burns in air to give off water vapour only. On cooling, the vapour will become water again. Therefore, the combustion of hydrogen will not cause global warming. As such, hydrogen is in fact a clean fuel. Besides, extracting hydrogen out from water by electrolysis would not be difficult, bearing in mind that the fossil fuels and nuclear energy will be exhausted eventually in future. Nevertheless, the safe use of the gas is a concern due to the wide range of flammability and explosion limits.||en_US|
|Abstract:||In this project, apart from literature review on the hydrogen combustion phenomenon, the combustion theory, the causes of the hydrogen gas explosion including the pressure fluctuation of gas in pipe as in the hydrogen explosion incident at Hamaoka Nuclear Power Station on 7 November 2001, and the ways to reduce the potential risks of hydrogen gas are discussed. On the other hand, another main objective of the study is to find out the people's response and their concerns in using solely hydrogen fuel by means of a survey. Using only hydrogen as domestic fuel is not yet common at the moment. The technology is not mature at this stage. As a matter of fact, such technology mainly comes from the advanced countries such as the USA. To complete the study, two actions were taken concurrently with one on surveying the literature and the other on searching practical experience and problems encountered by the gas manufacturers and suppliers in Hong Kong. The final safety design will be limited to the distribution and supply system to end-users only. Manufacture of the gas will not be included in this study.||en_US|
