Hydrogen fuel cells or engines are a useless joke. Toyota REALLY needs to be thinking more about power generation with Hydrogen and then electric cars so that their vehicle production can be universal across the world. Electricity is the most versatile form of energy and can be produced using lots of natural resources. I get it.....Japan has limited natural resources and the seawater around them is abundant (thus hydrogen), but the hydrogen vehicle makes zero sense literally anywhere else in the world and you're a GLOBAL COMPANY Toyota.
Also with all of the saltwater around them you'd think they'd be working on sodium-ion battery technology and how to utilize the salt they extract during the hydrogen production to be used in batteries, but no.....keep making ICE engines for some stupid reason. FFS Toyota.
Hydrogen fuel cell vehicles are EVs, have electric motors, and qualify when you talk about "power generation with Hydrogen" and "versatility of electricity". The hydrogen in the tanks is fed into an anode and oxygen into a cathode to power a circuit and drive an electric motor. It's an EV, but the 'battery' is hydrogen. FCEVs could be the key to shoring up a lot of conventional EV shortcomings; lithium-ion waste, electricity grid load, and lifespan, for instance. Combine that with the ICE vehicle in question in the article; Hydrogen ICE engines could provide routes for retrofitting existing combustion vehicles, adding additional demand to improve supply infrastructure and improve green hydrogen supply. These are well-warranted experiments for Toyota to be undertaking on the global stage; as crucial as any EV battery investigation!
And don't forget it's way faster to refill a hydrogen tank than an battery. Also, cars are such a big industry it's actually easier to not have a middleman (hydrogen -> ~~electric grid~~ -> EVs) because all the infrastructure would have to be built without any real need for it.
For now, this should change with solid state batteries
Is faster, but with modern EVs it’s really not a problem.
Depart home with 100%, drive for 4 hours, stop to grab an meal and use the facilities and the car is finished before you. Modern EVs take 15 minutes to go 20-80% charged.
Hydrogen is 3x less energy efficient than a battery electric vehicle. It certainly has use cases, but it came 20 years too late for light vehicles.
