Abstract
There are still safety concerns to use hydrogen as energy storage for commercial applications in a safe, efficient and cost-effective way. This paper is dedicated to discussion on safety improvement of hydrogen storage equipment for onboard applications. It provides a brief review, and then a quantitative risk assessment framework is presented. The procedure to execute the framework is elaborated in accordance with the associated mathematical equations. The thermal effect and high pressure leading to potential tank rupture are discussed. The probability of risk for human fatality is calculated. The calculated values using the case study data by following this framework are compared with the risk acceptance criteria. In the final stage of the analysis, the monetary values associated with human fatality are estimated as the result of risk evaluation. Finally, the future research directions are indicated, which include optimizing the risk in hydrogen storage using techniques such as central composite design, response surface method, machine learning and the numerical simulation; and sensitivity analysis of the solution using some available optimization software.
