Mr. Michael O'Leary:

There may well be a commercial hydrogen engine available, but we are talking about between 2040 and 2050. There is nothing on the horizon before then. The aircraft we are buying now will be flying from 2028 until 2045. There is no hydrogen technology at present. Rolls-Royce and easyJet did a test on a test cell this week. There will be no hydrogen in the immediate future. Since hydrogen is a flammable gas, there will be challenges. I will certainly not see hydrogen in my career in the aviation business and would probably go so far as to say I will not see it in my lifetime, but the end of that period is probably too far away.
