In terms of lives lost per unit of energy generated, nuclear power has caused fewer accidental deaths per unit of energy generated than all other major sources of energy generation. Energy produced by coal, petroleum, natural gas and hydropower has caused more deaths per unit of energy generated, from air pollution and energy accidents. This is found in the following comparisons, when the immediate nuclear related deaths from accidents are compared to the immediate deaths from these other energy sources, when the latent, or predicted, indirect cancer deaths from nuclear energy accidents are compared to the immediate deaths from the above energy sources, and when the combined immediate and indirect fatalities from nuclear power and all fossil fuels are compared, fatalities resulting from the mining of the necessary natural resources to power generation and to air pollution.[38] With these data, the use of nuclear power has been calculated to have prevented in the region of 1.8 million deaths between 1971 and 2009, by reducing the proportion of energy that would otherwise have been generated by fossil fuels, and is projected to continue to do so.

Recently, countries have introduced many policies to vigorously develop hydrogen energy (Wang et al., 2021). Hydrogen is a kind of efficient green energy, which is widely used in energy power, construction, chemical industry and other fields (Wang et al., 2022; Wang et al. 2022). Compared with ordinary combustible gas, hydrogen has a wider explosion limit range with relatively low ignition energy required for an explosion. The characteristics of hydrogen lead to an increased risk of accidents in the process of hydrogen energy application (Li et al. 2021; Zhang et al. 2022). Especially in specific environments, when the gas combustion reaches a detonation state, the resulting accident hazard may be further aggravated (Zhang 2016; Zhang, Liu, and Yan 2019). Research on the law of gas combustion can provide effective guidance for the control and prevention of energy accidents, such as the analysis of accident risk points or the reduction of accident injuries (Wang et al. 2018). At present, it is particularly important to study the explosion characteristics of hydrogen under certain specific conditions.
