Its so bad that only the largest space rockets use liquid H2. All the others use kerosene or the like. Either way, the Soviets tried gaseous fuels in the 80s - See Tu-155. They ran on liquid H2, CNG. If I recall, the weight increase didn't make it practical. On the other hand it was a turbine powered plane. It might work out with fuel cells (although you'd need a big and heavy compressor to run it) |
