The density of hydrogen is much lower than that of air (the density of air is 1.293 kg/m 3 under the standard conditions of 1 atmospheric pressure and 0 °C). In this case, hydrogen diffuses upward rapidly under the action of air buoyancy after leakage, and it does not easily accumulate to form a combustible gas mixture, which is conducive to its

Introduction. Energy, the engine of economic expansion, is essential for modern economic and social growth. Recently, energy demand growth and environmental issues are two of the world''s defining global issues [1].Fossil fuels represent approximately 90% of overall worldwide energy use [2].Energy requirement has risen steadily since
Proceedings of an expert workshop convened by the U.S. Department of Energy and Industry Canada, and hosted by the National Renewable Energy Laboratory and the California Air Resources Board, May 14-15, 2014, in Sacramento, California, to address the topic of hydrogen energy storage (HES).
The advantages of LH 2 storage lies in its high volumetric storage density (>60 g/L at 1 bar). However, the very high energy requirement of the current hydrogen liquefaction process and high rate of hydrogen loss due to boil-off (∼1–5%) pose two critical challenges for the commercialization of LH 2 storage technology.
The transition of the global energy market towards an environment-friendly, sustainable society requires a profound transformation from fossil fuel to zero carbon emission fuel. To cope with this goal production of renewable energy is accelerating worldwide. Hydrogen is a clean energy carrier, due to its clean combustion and
The use of hydrogen in ICEs, either in the form of direct injections or blended with other fuels, requires certain safety measures. The main safety issues are related to onboard hydrogen storage.
