Hopefully there is massive breakthroughs with green hydrogen,(reply>), @Aereto Storage isn't too bad of an issue, when compressed and stored cryogenically, it's ok to store and transport. But it still requires energy so currently only makes sense if you have excess renewable energy and the hydrogen sort of acts as the battery storage.,(reply>), @trevor Wilkinson <br>Hydrogen capture and compression would be nice, though storage is an issue when hydrogen leaks out through the best coatings available, and not worth installing electromagnetic repulsion to keep them in the container.,(reply>), Hydrogen is currently mainly a by-product from gas drilling. Producing Hydrogen other sources takes large amounts of electricity. Hydrogen production only makes sense with renewable energy production and even then for small cars, it's more efficient to put that electricity straight into a car than to transport the hydrogen to the vehicle so only makes sense where dense energy storage is needed like long distance trucks, planes and ships.,(reply>), hydrogen is being cut down by the big oil, and you guessed it...the big electro.
