The Hydrogen Discovery Series Ep4: How the Swiss Roll

Why does a hydrogen transportation model work in Switzerland and not in other European countries?

In Episode 4 of their Hydrogen Discovery series, Don and Nicole head to Switzerland to explore further, and to look at how cost has an implication on rolling out hydrogen technologies around the world.

Nice trucks Hyundai!👌 i hope too see Hyundai Trucks in Europe some where?👌

hydrogen cars can really ECONOMISE MORE FUEL COST THAN ELECTRIC CARS IF WE MODIFY OUR CURRENT HYDROGEN DISTRIBUTION APPROACH !
The biggest cause of hydrogen cost is that WE TRANSPORT HYDROGEN BY TRUCKS, IT IS EXPENSIVE. Just try to avoid to transport hydrogen by trucks, then hydrogen will be very cheap. It means that NEED TO PRODUCE HYDROGEN ON SITES (WHERE FILLING HYDROGEN), OR TRANSPORT HYDROGEN BY PIPE LINES.
So we need to make 1 or 4modifications :
1/ Distributed hydrogen production on sites : hydrogen filling stations should be equipped with electrolysers, so hydrogen filling stations can produce hydrogen on sites from electricity outlets, instead of just receiving hydrogen from other places. Thus avoid problem cost of transfer hydrogen by trucks. Besides, nets of electrolysing hydrogen filling stations are ideal solution/market for intermittent renewable energy.
It is new worldwide coming hydrogen distribution approach, so it opens markets of mobile small sized electrolysers. Electrolysers are not so expensive for hydrogen filling stations.
2/ Use compressed gas hydrogen batteries with mini household electrolysers/mini mobile electrolysers : small mobility vehicles/mobility machines/mobility robots/mobility drones …, will use hydrogen gas batteries (hydrogen gas battery =hydrogen fuel cell + compressed hydrogen gas ballon 200-300 bar). And each of these mobility machines can be sale with mini home electrolysers, so that owners can produce to fill hydrogen at homes (charge hydrogen batteries at home). Hydrogen ballon 300bar is enough, so that hydrogen battery 300bar(fuel cell +hydrogen ballon 300bar) can guarantee more energy capacity than best lithium batteries, and it guarantees that the size of hydrogen battery 300bar is not remarkable bigger than lithium battery of equivalent energy capacity. Of course 700bar allows more hydrogen storages, liquid hydrogen allows more hydrogen storage. But for hydrogen batteries, gas hydrogen ballons 300 bar are enough for balance of convertion ratio-ballon material-simplicity.
Hydrogen batteries 300bar + mini mobile electrolysers are ideal for two-wheel vehicles/small cars/small robots/drones and for trend of hydrogen mobility devices anywhere (easy to operate anywhere and easy to charge anywhere with electricity).
3/ hydrogen batteries for big station energy storage : Independent hydrogen batteries (hydrogen fuel cell + compressed hydrogen ballons > 300bar) + independent electrolyser is best variant. when excess energy, then run independent electrolyser. When need electricity, then run independent fuel cell. And intrigued working mechanism between independent fuel cell and independent electrolyser. That is all ! No complex automatic control system.
4/ hydrogen filling stations need to prefer using hydrogen pipe line than transporting hydrogen by trucks.
5/ The fundamental science dictates essential truth advantages of hydrogen.
Science : if a chemical energy storage mechanism is charged as quick as producing hydrogen, then this mechanism PRACTICALLY CANNOT HAVE ENERGY CONVERTION RATIO BETTER THAN ELECTROLYSIS PROCESS. Besides, it is possible to adjust electrolysis reaction speed to get energy convertion ratio of electrolysis better than any chemical batteries. The best one of all possible chemical batteries in earth conditions is HYDROGEN BATTERY. All revolutions of chemical batteries, lithium batteries, LFP batteries, LTO batteries, graphene batteries .. are for reaching to the features of hydrogen batteries
