Advocates for hydrogen fuel to be at the forefront of decarbonizing air transport know this journey must start with a series of first steps. One such step is being made in the UK with the launch of Project Heart, through which multiple partners are preparing to support trial operations at several regional airports.
One of these partners is Haskel, which is integrating its hydrogen compression system with an electrolyzer developed by Norway’s Nel Hydrogen to provide hydrogen for fuel cell-based propulsion trials on regional aircraft seating up to 19 passengers. The UK-based company has just published a white paper to assess the challenges and opportunities around providing the infrastructure needed for the move away from fossil fuels.
The rate at which aviation’s use of hydrogen as fuel gets scaled up would appear to be subject to a vicious circle similar to that which continues to constrain the adoption of any sustainable aviation fuel. With supplies remaining limited and distribution networks immature, the cost of the new fuel continues to be prohibitive by comparison with jet-A.
