“…This low level of knowledge in itself means that it is difficult to predict perception of a hydrogen leak in comparison to CO 2 or natural gas, since the lay public are likely not to know, for example, that hydrogen disperses more readily than CO 2 . Nonetheless, initial research (Mouli-Castillo et al, 2021) indicates that people can identify escaping odorised hydrogen at regulatory thresholds.…”

Hydrogen is set to play a part in delivering a net zero emissions future globally. However, previous research finds that risk perception issues are particularly challenging for emerging and potentially unfamiliar technologies. Hydrogen as a fuel falls into this category. Thus, while the hydrogen value chain could offer a range of potential environmental, economic and social benefits, it is imperative that the roll-out of hydrogen fits with societal expectations of how risk ought to be managed—and by whom. Communication and engagement are critical to ensure 1) communities and stakeholders are able to come to informed decisions on hydrogen and 2) developers, operators and regulators are able to respond to societal concerns and adapt practices appropriately.Within the hydrogen value chain, geological storage may be an important step, but could present challenges in terms of perceived safety. Lessons can be learned from international research and practice of CO2 and natural gas storage in geological formations [for carbon capture and storage (CCS) and power respectively] which may be relevant to hydrogen storage in salt caverns or porous sandstones. We draw on these analogues to present potential societal risk perception issues which may arise for geological storage of hydrogen. We argue that site-specific communication and engagement strategies, underpinned by broad-based principles covering the entire span of the project and a clear rationale for how hydrogen benefits the climate and the most vulnerable members of society under an energy crisis, will be critical to fostering societal support for geological hydrogen storage.

“…The work focused on establishing a comparative evaluations of 100% hydrogen against the current natural gas network. Areas which were investigated included the use and efficiency of odorants (Mouli-Castillo et al, 2020;Mouli-Castillo, Orr, et al, 2021), and the development of quantitative risk assessments for domestic properties . These complement the work done on refuelling infrastructure critical for the uptake of hydrogen for road transportation (Tsunemi et al, 2019).…”

“…Because hydrogen cannot be detected directly by the human senses by odor or color, and due to its small atomic radius [ 18 , 19 ], it is necessary to perform this detection by means of specialized sensors [ 3 , 4 , 19 , 20 ]. With regard to the lack of color and odor of hydrogen, current studies aim to attribute these characteristics to it [ 21 ]. This is especially applicable for certain areas where its release and accumulation are imminent, in order to facilitate its detection, including by human means.…”

The development of hydrogen sensors has acquired a great interest from researchers for safety in fields such as chemical industry, metallurgy, pharmaceutics or power generation, as well as due to hydrogen’s introduction as fuel in vehicles. Several types of sensors have been developed for hydrogen detection, including resistive, surface acoustic wave, optical or conductometric sensors. The properties of the material of the sensitive area of the sensor are of great importance for establishing its performance. Besides the nature of the material, an important role for its final properties is played by the synthesis method used and the parameters used during the synthesis. The present paper highlights recent results in the field of hydrogen detection, obtained using four of the well-known synthesis and deposition methods: sol-gel, co-precipitation, spin-coating and pulsed laser deposition (PLD). Sensors with very good results have been achieved by these methods, which gives an encouraging perspective for their use in obtaining commercial hydrogen sensors and their application in common areas for society.
