While hydrogen is regularly discussed as a possible option for storing regenerative energies, its low minimum ignition energy and broad range of explosive concentrations pose safety challenges regarding hydrogen storage, and there are also challenges related to hydrogen production and transport and at the point of use.
In addition to the inherent safety issues of hydrogen, which are mainly related to its wide flammability range, its easy ignitability, and the fact that it can detonate quickly and easily, one of the main issues is that it is difficult to perform experimental measures for each type of production process, storage, transport, and use.
There are serious safety concerns associated with the hydrogen process. These concerns need to be thoroughly understood and addressed to ensure its safe operation. To better understand the safety challenges of hydrogen use, application, and process, it is essential to undertake a detailed risk analysis.
Hydrogen has unique physical and chemical properties that make it an attractive option for energy storage, transport, and use. However, hydrogen also poses fire/explosion risks due to its high flammability. Hydrogen is a colourless, odourless, and tasteless gas that is highly flammable in air and can ignite at concentrations as low as 4%.
The most hazardous hydrogen scenario occur in the transmission and application process. Hydrogen jet fire and explosion are the key hazard components for compressed hydrogen. Accidental release of liquid hydrogen causes flash evaporation and evaporation that may cause pool fire. CFD simulations are reliable tools for hydrogen safety assessment.
The delayed explosion of an accidental release of hydrogen under high pressure is an important risk scenario for safety studies of production plants, transport lines, and charging lines for fuel cell vehicles.
Infrastructure development: One of the biggest challenges facing the hydrogen industry is the development of infrastructure for the production, transport, storage, and distribution of hydrogen. This includes the construction of pipelines, storage facilities, and hydrogen refuelling stations for transport.
While hydrogen is regularly discussed as a possible option for storing regenerative energies, its low minimum ignition energy and broad range of explosive concentrations pose safety challenges regarding hydrogen storage, and there are also challenges related to hydrogen production and transport and at the point of use.

Dihydrogen (H2), commonly named ''hydrogen'', is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen development should also meet the seventh goal of ''affordable and clean energy'' of …
Also, considering the significant amounts of energy wasted during off-peak times at several renewable energy power plants without suitable energy storage, the use of this energy to drive the water electrolysis process can reduce hydrogen production costs down further.
