It's about the pressure vessel's weight. That goes up with the square of the linear dimension while the quantity of fuel goes with that cubed. I don't think finding space to fit it is the problem. In the case of normal fuel, there's no pressure vessel so it can be much lighter.
- pfdietz 4y agoIn a tank dominated by pressure loads, wall thickness increases in proportion to the linear dimensions of the tank, so no, tank mass is proportional to volume.
