For me I feel disappointed that hydrogen fuel cells never took off. Toyota spent a fortune researching them, making them safe to avoid Hindenburg disaster type imagery. But it never really seems to have caught on. You can add a hydrogen pumping station to an existing petrol station too. Plus you don't need to add a charging station to your house. So there are lots of pluses.

Currently hydrogen fuel cells have a slight range advantage and speed of refueling advantage. However the efficiency of creating and compressing / liquifying hydrogen and then turning back into electricity in the cell is around half that of just charging a battery.

Fuels cells currently also don't put out as much burst power nor can they store energy from regenerative braking so a fuel cell car needs a traction buffer battery like a hybrid.

Pretty skeptical for hydrogen fuel cells at this point, battery cost are dropping fast while energy density going up along with charge rate, fuel cells are being left behind pretty quick.

I don't need to "add a charging station to my house". I already have multiple outlets outside of my house. If I want to be fancy, I can spend 500-1500€ and add a real Type2 charger with load balancing and remote control features.

Just FYI about hydrogen cars:

- They are just EVs with smaller batteries, a large part of the battery is replaced with a hydrogen tank + fuel cell. - The WHOLE hydrogen storage system will need to be replaced fully every 10 or so years. Hydrogen is really really small and has a habit of escaping every vessel you try to keep it in. - Currently the government subsidised price for H2 in Germany is 9.5€/kg. It takes about 1kg of hydrogen to drive 100km. Would you pay almost 10€/100km to drive a car? While an EV can do the same trip for 1-3€?

Do you know the amount of bureaucracy needed to store multiple hundreds of kg of pressurised highly flammable gas (hydrogen) anywhere?

Compare that to the amount of work needed to install what is essentially a fancy power outlet.

I initially thought they would take off, when I didn't know about the tech. Then I found out they charge batteries so they kind of have the worst of both worlds.

Whoever designs a cheap, safe, durable, light, easily mass produced hydrogen storage material will be a multi billionaire.

A charging station at home is a net benefit in my book. That’s a good chunk of time saved each month.
