A H2-based fuel cell application that actualy makes sense (probably). Combined with 'Wingsail' technolgy (with the 'sails' covered in thin film PV to boot), you could really have a practical - but ecologically sound - alternative to ocean traversing bunker-oil-fuelled cargo ships. Or we improve cross-continental rail services massively. But that's a *lot* of extra trains and the railways to carry them - and you are still stuck with a lot of trains running on diesel and at getting between continents where it's ships (or planes/rockets) or nothing. JimFox April 15, 2020 06:53 AM Encouraging, within its limitations. I believe the ultimate answer (in maybe 10 yrs) is Gen 4 Molten Salt reactors, fail-safe & economical, over their lifetime. paul314 April 15, 2020 07:51 AM And there aren't a whole lot of ports where these behemoths dock, so the question of rolling out fueling intrastructure everywhere isn't a big deal. I wonder how much cargo capacity you would have to forgo to make long-distance travel feasible. Somehow with that prediction of $600 trillion in economic losses over the next 80 years, a few percent inefficiency doesn't seem like as big a deal. alexD April 15, 2020 07:52 AM "It's going to take several generations of battery development to enable long-range electric shipping operations," of course it will but if we never get it started, it will never fulfill the promises. FB36 April 15, 2020 08:54 AM IMHO, using hydrogen as fuel for any kind of land/air/sea vehicle is extremely bad idea! Because any leak/rupture of a hydrogen fuel tank could easily cause a massive explosion (not just a fire)! Hydrogen is no ordinary fuel! & just imagine, if a container ship exploded like a giant bomb! Kpar April 15, 2020 03:27 PM Fears of a "hydrogen bomb" are not justified. H2 can be safely handled with known technology- as the H2indenberg Society has shown.My complaint is that people keep thinking of H2 as a fuel- it is not. That said, H2 does not exist in a usable form on Planet Earth, it must be made via electricity or radiation, with the associated fuel costs and efficiency losses. H2 is only an energy storage system. HSU will have its day again April 19, 2020 05:24 AM Any program that is cost effective but not controlled and a monopolistic income earner for one of the cartels does not stand a chance.This is evident from the 'on board, on demand' Hydrogen fuelling system used by Aeroflot for twelve years prior to the breakup of the USSR!!!!This is the prime hindrance. Ken Gage April 20, 2020 01:01 AM Cool little article. But you don't have to say hydrogen energy has "difficulties with storage, transport and inefficient generation" unless you're a Big Oil guy, because that simply isn't true. Hydrogen generation through electrolysis is easy and more efficient than extracting crude oil and refining it.
