That is out of our scope as a business but it is something we have found we have to address head on with our customers and airport partners. They want to understand the whole logistics and associated safety from green H2 production to aircraft tank. We don't have it all figured out yet but we are working with some great partners on the problem. We have created a Hydrogen Flight Alliance here in Brisbane https://newsroom.bne.com.au/hydrogen-flight-alliance-launche... that includes, BOC (a Linde Company) and H2EC who are tackling the logistics and re-fueling of liquid hydrogen. Note that we are using liquid H2, which is more expensive than gas, but comes with a variety of benefits, one of which is that it is stored at low pressure. We could opt to store it just over ambient pressure but we will most likely go with storing it < 10 bar - much less than the 350 - 900 bar, that gaseous H2 is typically stored at.

Good, infrastructure matters: Birdseye, famous for fish, got freezers into supermarkets; Edison, famous for lights, constructed generators; Tesla (co), famous for cars, constructed charging stations.
