Requiring 'massive strong tanks' for H2 seems less of an issue as existing H2 transport systems (cars, trains, drones, ferries, buses, vans, trucks, etc) leverage modern materials and construction techniques to implement smaller, strong tanks, making H2 transport evermore viable, cheaper and more numerous. H2 research is developing options to store H2 in various liquid and solid form at normal range temperature and pressures. I believe we need to think differently if we are to transition from 'dirty' fossil fuel burning transport to 'cleaner' non-fossil fuel burning transport, or figure out how to use/burn fossil fuels without the current pollution and GHG side effects. As some attribute to Einstein' “The definition of insanity is doing the same thing over and over again, but expecting different results.” Thus, why would any future transport solution (say by 2040) involve 'burning' fossil fuels be a 'clean(er) transport' solution? A hybrid petrol/diesel ICE/EV uses a heavy ICE, that takes and burns heavy fuel from a fuel tank/fuel store, to charge heavy batteries and generate electrons to power the electric drive, and a heavy exhaust and cooling system to remove waste heat and gases when the ICE is being used, and switches to a heavy battery to deliver electrons when the ICE isn't required. So hybrids need to carry and move many 'dead weight' heavy elements of the car (ICE, fuel in a fuel tank, exhaust and cooling systems, and batteries) that consume energy/fuel to move their weight that should be going into vehicle range and performance. Like any technology, H2 transport technology is improving in efficiency, weight, storage, output, cost, etc, all the time. I'm not dismissing H2 in transportation too easily or early, as BEVs, hybrid petrol/diesel ICE/EVs (as an interim 'bridging technology'), FCEVs, H2ICEs, etc, all have a part to play in future transport transition to Low Emission Transport - just as we have petrol, diesel, LPG, EV mix at the moment, low carbon options need to be matched with the transport requirement. Will be interesting to have this conversation in 2025, 2030, 2035, and 2040 to see where transport technology has journeyed to.
