The UK government’s Jet Zero Taskforce reports that first commercial gaseous-hydrogen flights from a UK airport by 2030 are feasible, especially on sub-regional routes with 9-19 seat aircraft. The report stresses the need for scaling to liquid hydrogen for larger aircraft to make a substantial environmental impact, as regional aircraft contribute only about 3% of UK aviation CO2 emissions.

Infrastructure development is lagging, with airports needing investment justification linked to aircraft demand. The study suggests that 80% of hydrogen deployment benefits could be achieved through just 20 strategic European airports. Most hydrogen demand before 2050 will be for SAF production, with recommendations for a national zero-emission flight program and infrastructure support.
