Toyota’s hidden engine has been unveiled—it burns hydrogen and only emits water, with up to 45% thermal efficiency—and passenger and van models are already ready

 

Toyota has just launched an engine that doesn’t pollute! When everyone seemed sure that the future of cars was all about plugs, Toyota comes out with this: a combustion engine that runs on hydrogen and emits only water vapor. Not a trace of CO₂, and with numbers that make many electric cars look bad, ouch. What if we rushed into demonizing traditional engines?!

 

The prototype offers up to 400 horsepower and 45% thermal efficiency, something that until now was only seen in the best diesel engines on the market. Toyota doesn’t just want to bring combustion back to life, it wants to do it cleanly. And yes, they’re pulling it off. What doesn’t Toyota manage to do?

Hydrogen engines

 

We’re talking about pure combustion engines, which instead of burning gasoline, burn hydrogen. That way you keep the traditional driving feel  but without polluting anything!

The result is an engine that runs like a sports car, has the soul of the old ones and doesn’t leave behind dangerous waste! An all-in-one that might appeal to those who still haven’t fallen for electric cars!

There isn't a week goes by without Toyota announcing something that will kill EV's, it's all nonsense.

 

If you want to know why Toyota's V8 Hydrogen engine will fail, watch the video, or maybe you're happy with 80 miles range?

 

 

Yes, Hydrogen (H2) is great.

 

It cost five times more per kilometer than a battery electric car.
 

You take your electricity and instead of putting it straight in your battery car, you electrolyze water to make hydrogen and oxygen, you then use electricity to compress that so you can put it into tankers. Then you drive the tankers to your local fuel station using hydrogen in the process. Then you use more electricity to transfer into the fuel station tanks. Then you use more electricity to pump it into your car. then your car probably uses a fuel cell which is about 50% efficient as it wastes a lot in heat reducing the whole thing to 20% of the efficiency of having a battery electric car in the first place.

 

Sorry, you're post was for a Hydrogen Internal Combustion Engine not a Fuel Cell, how does 8 times more expensive to run than EV grab you?

 

So consumers will love the hydrogen car because it cost five to eight times more to run.

 

Where do I order one?

 

Post Script:  Hydrogen has been tried in a few countries, every one failed.  Even the Hydrogen production companies are saying quite clearly that Hydrogen will not be used in passenger cars.

Sorry my church of electric cars was locked today so I couldn't worship.

And what idiot would want that.  The smooth, quiet, better performance is the only thing I notice, between the ICEV & BEV version of our MG ZS, as I owned both. 

 

Aside from the high savings of energizing, I don't need to worry about the extra 2000+ parts of an ICE failing.   ICEV will never perform better than a BEV.

 

So Toyota is simply keeping up with the POS H cars in the USA, mostly T. Miras, that has virtually no fueling station network.  Why Toyota's profits & market share, will continue to drop.  Nobody wants H cars.

 

A decade after H cars have been available in the USA ... AND ...

am guessing you own a chinese sewing machine <deleted>box given your butthurt over toyota hydrgoen announcement.

Does it really make sense to convert hydrogen to electric to run electric motors, or simply use electric, stored in a battery ?

 

Why complicate things, along with the energy used to make and transport hydrogen. 

 

And Toyota, coming out with ICE that runs on H, is just stupid.  Less practical than it's FCEV.

Which Toyota Hydrogen announcement?

 

The one this month? or the one in every other month for the last 10 years?

Costs of manufacturing Hydrogen, and the cars that can run on it, will come down in time. 

 

What happens if we keep going with electric cars when everyone has one? Given the charging time, how long will the queue be at the charging stations? 

 

I want the character and soul of the ICE with zero pollution.

 

Give me a Ferrari and Sunday morning I'll drag body out of bed, go find a tunnel, wind the windows down and floor it just to hear that addictive sound. 

Give me an electric car and Sunday morning I'm staying in bed.

BMW has been dabbling in H2 cars for the last 45 years. About 25 years before China thought of electric ones.

 

Well hydrogen cars are already being used as there is a refill station at Haneda airport. I saw them fueling up at it when I returned my rental car next door. (And the brand new Japanese Prius is a great drive, Tokyo - Mt Fuji return cost about 150 baht in fuel)

Hydrogen car sales in Japan have fallen by 83% over the past two years

 

Hydrogen has failed or is failing in the domestic passenger car market everywhere it has been trialed

And here I am.   Hoping the owner of the Ferrari that's parked on the ground floor of the condominium parking garage, starts that thing up as I am walking through the garage.   Before I leave Thailand on the 28th!

 

So sad

I'm mad

I haven't heard that bad

boy start and run!

It is misleading to say, "That way you keep the traditional driving feel  but without polluting anything!"

True, the engine itself doesn't pollute, except possible nitrogen oxides.  However, some methods of manufacturing the hydrogen fuel are polluting.

And wait and see the cost of electricity will go up , and the Demand for that  keeps going up ,that will push the price of the electricity up .

Not really, every household relies on electricity to live.  On average an EV adds about 4kwhrs per day to the average consumption.

does that mean, just as a comparison, that with every newly installed aircon the price of electricity will increase in the future? because running one new aircon for 10 hours a day uses about the same amount of electricity as an electric car for the average 20–30 km of daily driving ... 

 

the switch to electric mobility will not happen overnight, it will take decades... during this time, many new things will be invented ... 

 

to produce diesel or gasoline, energy is also needed ... this energy saving when switching to electric mobility must also be included in the calculation ... so the additional consumption for electric mobility is actually smaller than many people calculate ...

what about the cost to run the coffee machines at charging stations with all those soy boi's sucking down mocha <deleted> chino latte's waiting for their sewing machines to charge.
