The WTCs collapsed because of a myriad of reasons, I doubt very much that if an equivalent hydrogen powered jet had crashed into them the outcome would have been different. iirc the general consensus is that many (most?) skyscrapers would continue to stand after being hit by a plane in the same manner as the WTC towers, and specifically the all-steel no concrete construction combined with some other problematic factors in the design was the reason for the total collapse.
