The International Chamber of Shipping (ICS) has released a comprehensive report focusing on the potential of hydrogen as an energy carrier and feedstock to reduce emissions in various industrial sectors, particularly those hard to decarbonise. The report titled 'Turning hydrogen demand into reality: Which sectors come first?' highlights the critical role of clean hydrogen in decarbonisation efforts and discusses the demand dynamics of zero-emission fuels. Europe, South Korea, and Japan are identified as primary markets driving hydrogen demand, with Europe setting ambitious targets for hydrogen production by 2030. The report underlines the need for a substantial increase in the fleet to transport hydrogen by ship to meet the growing global demand, estimating the requirement of hundreds of new hydrogen vessels. Additionally, the report stresses the unprecedented scale of renewable electricity needed for green hydrogen production, indicating both significant opportunities and challenges in shifting towards zero-emission fuels in industrial sectors.
