I drive a Prius, it's a skill to drive efficiently. The main tip: do not use the gas pedal if you're going to brake soon anyway. Think of the brakes as wasting gas, then you'll use the brakes sparingly, and the safe way to do that is by not accelerating unnecessarily.
Just think of this. You see some kid in a red sports car at a stop sign. They blast off quickly, then after one block they brake hard for the next stop sign. That's wasting gas, brake pads, and creating more emissions in that area too.
Other than that, accelerate slowly, watch your RPMs, stay around 60 mph, take it easy on hills, there's a lot to it, even without a Prius Regen style battery.

More like an electric car, if it's a hydrogen fuel cell car (I'm not sure if all hydrogen cars are that or if there's another variant that combusts the hydrogen)
Drives like an electric, refuels like a liquid fuel car (it uses a compressor, not electric charge).
If by "electric" you mean "Prius", you're right.
Tesla's and similar cars have great acceleration because they support massive currents at high voltages. They need this to support fast charging, the incremental cost of adding a high torque motor is small.
Hydrogen cars have tiny batteries that don't need to support fast charging. Like a Prius.

#84What is the appeal of a hydrogen car vs an eletric car? The range appears to be similar, but being able to charge at home is so much more convenient.
Same question from me also. Also, hydrogen is highly explosive, so how can that be safely used in cars without detonating a la Hindenburg whenever there's a collision?

Basically drive like you have no brakes.

I personally think we'll see charging poles next to most public parking spaces before we see a sufficiently built out network of H2 'gas stations'.
I think this underestimates the massive infrastructure investments those charging poles would need to work. I live in a medium density European town (about 1000 inhabitants/km2, think 4-5 story buildings on average). In residential areas the whole street is lined with parked cars on both sides. To charge these, one would need something like 1MW charging per every 4 cars, which means every 20m of the road, on both sid…
Autonomy and ride sharing is the only answer to this problem. Most people who live a dense European town are not driving long distances every day. SO the should just rent a car on the days they need one or take an autonomous or non-autonomous taxi. Those cars do not need to be parked on those specific streets at night.

I think it’s precisely that; with electric, there’s no special product to sell you. With hydrogen, or ethanol, the old oil and gas companies can more easily pivot into simply selling another chemical product. With electric cars, the oil and gas companies are like cable TV in the age of the internet; their days are numbered, and they fear it like nothing else. (Also, governments have nothing to levy special taxes on i…

> 100% electric cars isn’t feasible for countries like Japan
Japan heavily subsidises research into Hydrogen. This over anything else, e.g. electric. Quoting a Japanese car manufacturer is therefore a bit biased. Japan has two different energy grids btw, one runs at 50 Hz, the other at 60 Hz. Japan made some really strange decisions regarding their electric grid. That makes Japan unique, it isn't common to have such problems.
For most countries the additional electric requirements aren't that significant. Though there will need to be some behavioural change (possibly helped by some technology). E.g. don't charge everything immediately at once, but align the supply and demand. Meaning, don't charge everything at once, charge more when there's an over supply (e.g. windy day/hour).

I disagree with what he says about co2 and the old “you have to make electricity with something” argument. It wasn’t until I bought a Tesla and did the math myself that I realized how inefficient gas cars are compared to an electricity generating power plant. My equivalent mpg with my electricity rate is something on the order of 150-180 mpg. For trips where we can charge at home (most of our miles) it is a 1/3 of the cost of our Prius to drive.

#89Hydrogen is not dead, all the hate it has been getting from Musk made people leave the space. If somebody bets on it right now it seems like a better bet compared to say 5 years ago.
The whole promotional attitude towards EV will cause an EV winter when the rubber meets the road and things aren't as rosy as advertised. Mark my words. It's already happening .

Most people can't charge at home (because most people live in multi-story houses in a bigger cities and don't have a garage to charge in), so refueling in 2min at a gas station still has appeal.
I can charge at work and the grocery store. Still much nicer than going to the gas station, especially in the winter.
You can now, but it doesn't scale that well if electric car usage increases 10-fold for example (which is still a very little fraction of total).
