Hydrogen fuel costs have gotten way out of control. Cost to refill a Carrack from 75% to 100% is over 10K auec. In no universe does this make sense as hydrogen is the single most common element in the universe and exceedingly easy to harvest and transport. Hydrogen is expensive on earth only due to lack of space infrastructure. With the high rates of hydro consumption and the fact that missions are typically between 2000 and 6000 credits in payout you have a situation where fuel costs can exceed income with larger fuel hungry ships. You need to knock at least an entire digit off refueling costs for hydrogen fuel. The only saving grace is that the PTU provides essentially unlimited credits for testing purposes but once this hits live unless hydrogen fuel prices are brought down to sane levels it will be difficult to run missions and cargo in a way that keeps up with fueling costs for larger ships. When blowing up and paying the claim expedite fee is cheaper than refueling you have a big problem as fuel is supposed to be a trivial expense......
