Economics: The production from low carbon hydrogen at scale is highly capital intensive, requiring significant investment to deliver. It also has significant operating costs, including low carbon electricity supply for “Green” hydrogen or feedstock, and CO2 Transport and Storage (T&S) costs for “Blue” hydrogen. The costs of low carbon hydrogen are therefore also likely to be significant. It must also compete with other options to decarbonise in the transition to net zero. Support in low carbon hydrogen production, including CCUS technology will therefore be extremely important to facilitate the transition.
To enable the safe uptake of hydrogen technologies, it is important to develop the international scientific evidence base on the potential risks to safety and how to control them effectively. The International Association for Hydrogen Safety (known as IA HySAFE) is leading global efforts to ensure this. HSE hosted the 2018 IA HySAFE Biennial Research Priorities Workshop. A panel of international experts presented during nine key topic sessions including Applications, Storage, Accident Physics, Materials, and General Aspects of Safety. Further information can be found in the workshop report [29].
