Attendees at the Hydrogen Technology Expo in Hamburg, Germany, highlighted the importance of collaboration between policymakers and industry developers to establish a global hydrogen trade. The panel of representatives from Scotland, Germany, and Canada stressed the significance of harmonisation among countries and between the public and private sectors to achieve the Net Zero by 2050 scenario, which requires over 500 million tonnes of hydrogen production for global decarbonisation. They underlined the necessity for coordinated efforts to align policies, standards, and investments across borders. The Scottish Minister for Climate Action, Alasdair Allan, stated that government funding alone is insufficient for such a massive endeavor and that collaboration beyond governmental resources is essential for success.
