It did. Energy density of h2 is 3x that of kerosene, by weight. By volume it is a very different story.

It does. Energy density of 1 gram of hydrogen vs 1 gram of any other fuel compared to 1 liter of hydrogen vs 1 liter of any other fuel. They are different measures.
Both are valid ways of measuring energy density.

im not really sold on hydrogen either, but weight is actually extremely important when it comes to shipping and transport fuel efficiency. You literally burn less fuel moving less weight.
