Toyota debuts hydrogen-fueled race car as auto racing begins shift away from gas guzzlers

Why would anyone want to risk their life participating in such dangerous activity - one crash, and the hydrogen bomb goes up, pretty much unsurvivable despite all their safety hype.

IF people are going to continue to race cars around tracks all over the world, mind-numbingly tedious and pointless as this is, then surely it's high-time that a synthetic fuel was developed to replace petrol. Surely even the smartest chemists / scientists in the world must be able to this. Until then, let's just stop wasting the earth's resources unnecessarily.

People are concerned with safe and easily accessible energy supplies. It is no use for using hydrogen which are not easily accessible - compare with electricity.

Toyota can promote hydrogen on racing car events and they are welcome. But the main stream should be electricity.

Fantastic idea Toyota, and thanks for seeing how far this can go.

So there’s now this budding ability to burn liquid hydrogen, added to burning gaseous hydrogen in an ICE engine, and thirdly of course HFCV hydrogen fuel cell EV vehicles.

With Le Mans creating a hydrogen category from 2030, the future looks promising for alternatives to straight EV power units. No point forcing us to put all our eggs in one basket, especially when the wobbly world does not yet have sufficient electricity generating capacity.

Hydrogen huh... good luck with that!

Hydrogen produced from fossil fuels-ironic!

A gasoline burn is much worse than a hydrogen burn. Tech has developed for both. Imagine if after the first gasoline car accident that they banned gasoline. Hydrogen is just as safe now

How much gas was guzzled to produce the hydrogen for the new race car? Currently more than 95% of hydrogen is produced by burning fossil fuels.

Liquid hydrogen is extremely dangerous, and must be kept at -250 degrees. Hydrogen in gas form is safer, but a race car wouldn’t have room for a fuel tank necessary to run the engine for more than a few laps.

Currently yes, but there is a future to work towards.

The demand and the infrastructure will grow together, and the amount of green hydrogen generation will grow out of necessity. No brainer.

If you don’t like it, no problem, stick with EV, but we will hopefully all have a choice.

Don't know about this lot, but the article does say water electrolysis can be used to get green hydrogen. It's electrically splitting the hydrogen from the oxygen. Solar, wind, or even nuclear (mostly green energy) can be used to generate. And water surrounds us.

From a unit of green energy you can either power a single hydrogen combustion car; or 20 battery vehicles. Hydrogen is simply too inefficient and impractical to make it ever into mainstream.

Ten reasons why hydrogen could even be better than EVs. Some ideas I had not considered before, such as the ability to capture hydrogen from existing industrial emissions, and the ability to store the hydrogen created.
