    Australian Chief scientist Alan Finkel maintains he has the answer to building new energy technology while holding onto fossil fuel powerhouse coal. Turn the abundant fossil fuels into HYDROGEN. Finkel told the 2019 Australian Clean Energy Summit that the world would need to build 70 times more wind and solar than already existed at the end of 2018 (along with the associated storage – pumped hydro, and batteries) for those technologies to displace the energy we get from coal, gas, and oil.

    “Many people, not just me, will argue we will need a means of storing electricity in a high-density transportable form,” he told the summit, “and the leading candidate … is hydrogen”. Australia could, in say 20 to 30 years, export 30 megatonnes of hydrogen annually to match the energy exported in the 70 Mt of LNG we shipped in 2018, since hydrogen has 2.4 times the energy density of LNG"

    The general problem with hydrogen is that it is so darned difficult to store. I think some folks are working on a chemical "sponge" out of magnesium (I think) to enable it to be used practically for cars. There are some hydrogen buses, but I don't know what the storage method is. They are all within cities, so they stay close to their refueling source. The Germans in WW1 used cow gut to line the dirigible tanks, as nothing they had at the time was impermeable to hydrogen, but the gut came close and was self-sealing to an extent. It would be a good source of energy, but would soon become a "pollutant, just as CO2 has, for water vapor is THE most significant greenhouse gas on the planet.
