The world is getting closer to witnessing an historic moment as the first ever unmanned transatlantic hydrogen flight is in the works. H3 Dynamics, an aerospace engineering firm who has been developing an all-electric hydrogen propulsion system, is teaming up with Hylium, an R&D (Research and Development) venture spin-off from the Korean Institute of Science and Technology, in order to make use of its proprietary cryogenic liquid hydrogen storage technology. The benefit of liquid hydrogen over gaseous hydrogen is an increase in density which in turn leads to a larger energy density – more hydrogen molecules occupy a given volume in liquid form than in gaseous form, hence more bonds can be broken and more electrons can be extracted by…
