Inherent Safety and Health Assessment of Hydrogen Storage Process

Abstract

The consumption of fossil fuel as the main energy sources results in the production of a large amount of greenhouse gases, such as carbon dioxide and methane, which are one of the main causes of climate change. Research and development as well as implementation of clean energy has been put as high priority in various countries to combat this issue. Hydrogen is one of the most promoted energy sources of clean energy due to its environmental benefits and high energy production. Major development can be seen in the field of hydrogen energy in the past few years from the stage of hydrogen production until the stage of hydrogen storage. This further enhanced the importance of hydrogen safety considerations. Safety considerations usually begins with hazard identification which can be done using various inherent safety assessment tools. Even though there a lot of inherent safety assessment methods that are available, the method that can be used to specifically assess the safety and health level of hydrogen storage is lacking. The aim of this paper is to introduce the development of an inherent safety and health assessment method specifically for hydrogen storage processes. This research begins with the identification of safety and health hazard parameters that existed in hydrogen storage process. Then, a hazard scoring index for safety and health parameters focusing on hydrogen storage is developed. At the current phase, this research will only focus on material-based chemisorption in stationary hydrogen storage technique. The scoring development for inherent safety and health assessment will be done quantitatively using logistic function. The inherent safety and health assessment methods developed will rank the chemicals involved according to their hazard level.
