In what sense is hydrogen more "dense" than most current battery technologies in storing energy? By volume? By mass? I thought that several battery technologies are already better than (economically) stored hydrogen for storing energy, but I would be delighted to see some participant here on Hacker News "show the work" to compare storage of electrical energy through different means and discuss the trade-offs.
