The Oxford Institute for Energy Studies emphasizes the crucial role of addressing hydrogen leakage throughout its supply chain to enhance its sustainability. The institute highlights the environmental implications of hydrogen leakage, such as extending the atmospheric lifetime of methane and contributing to changes in ozone levels. They stress the need for innovations like containment materials and real-time monitoring systems, alongside regulatory standards and economic incentives for low-leakage technologies. Italy has revealed its national hydrogen strategy, envisioning a modest role for hydrogen in the country's energy mix by 2030 while emphasizing long-term infrastructure potential and plans to become a hydrogen transit hub linking regions. Air Liquide plans to produce renewable hydrogen at TotalEnergies' site in Southern France, using biogenic by-products for production. RIC Energy in Spain has received authorization for its H2-Valladolid green hydrogen project, featuring a 10 MW production plant powered by nearby photovoltaic plants.
