Hydrogen-powered GR Yaris debuts in Europe

Toyota used the Ypres Rally to demonstrate its GR Yaris H2 outside of Japan for the first time


When we last talked about Toyota’s hydrogen-powered GR Yaris, it kicked off an extensive discussion in the forums about the pros and cons of hydrogen fuel in general. Whether you think it a pointless, inefficient sideshow or a nailed-on certainty when it comes to the future of internal combustion, Toyota is still quite keen on the idea (naturally it is also keen on several other ideas, too) and has underlined that fact by demonstrating the car on public roads outside Japan for the first time. 

And we’re not talking a trundle round an industrial estate, either. Oh no. The GR Yaris H2 featured in none other than the ninth round of the WRC in Ypres. Okay, so it was only on a single stage, and the car ran ahead of the safety car before the real action kicked off - but still, it was an enthusiastic squirt down a 15km course of ‘extremely narrow farm roads that ran along fields and between houses’. It doesn’t get anymore ‘real-world’ than that. 

Moreover, it was driven by none other than Akio Toyoda in his ‘Morizo’ chief test driver guise. And Toyota's guv’nor can’t sit in a GR Yaris without driving it enthusiastically - especially when he’s got four-time WRC champion Juha Kankkunen doing the pace notes. In case you’d forgotten, the H2 is said to be more or less identical to the standard GR, with only a strengthened block and modified injection system distinguishing the three-cylinder motor from its petrol-chewing equivalent. 

Of course, the appearance of the car in Belgium is unlikely to have PHers opting for a different side of the fence in the ongoing debate about hydrogen fuel - but for what it’s worth, there does seem to be an ongoing correlation between Toyoda’s proximity to a project and Toyota’s in-house enthusiasm for it going forward. And while he was quick to highlight the presence of a Mirai at the event (the manufacturer’s current hydrogen fuel-cell car), it’s readily apparent that the CEO is still very keen on the idea of conventional combustion engines powered by unconventional means. 

Kankkunen is predictably partial to the idea, too. “The hydrogen engine put out solid torque, making it no different from a gasoline engine. Because they emit zero CO2, I believe hydrogen engines will become one of the options for achieving carbon neutrality not only in the world of motorsports but also in the world of everyday cars.” 

It’s worth noting that Toyota still hasn’t put a figure next to that ‘solid torque’, and has so far declined to relate performance figures for the H2 either. The concept remains a work in progress, as do the firm’s other research programmes - including running a modified Corolla in Japan's Super Taikyu race series. But, as Toyoda stated for the record when the car was revealed last year, the real appeal of hydrogen-based fuelling is the delivery of “almost zero emissions while retaining the acoustic and sensory sensations typical for combustion engines." Extensive production-based hurdles aside, that sentiment still sounds pretty good to us.

Hydrogen has always been my preferred vision of the future, and before the BEV naysayers chip in, yes there are production and technology hurdles to overcome, but if the worlds biggest car company is behind it, there is hope.

Hydrogen has to be the way forward.

Electric just isn't convenient enough, and it's going to be a very long time before it is.

I also see a future for hydrogen. Although it might be in trucks, farm machinery and heavy construction and industrial plant where batteries just don’t stack up.
JCB are doing some very serious work on it.

And if it allows some enthusiastic cars to be ICE’d then that’s a bonus too.
Lots of work ongoing at the minute to increase green hydrogen and massively improve storage.
It isnt beyond the wit of man to see the large pressure vessels needed buried under filling stations similar to petrol tanks now and modified pumps springing up. Just needs some of the major manufactures to make the right noises about utilising it in their future models.
Maybe not every filling station but several in every major town and city…….

The problem is that it's not really an engineering problem, but more a scientific one. It's quite possible that we'll find a reasonably efficient way of producing hydrogen (or more likely a very cheap, environmentally not too damaging, way to produce a lot of electricity which makes the inefficiency of electrolysis a moot point) but if so it'll be a university physics department which discovers it, not a car company. Such things tend to take decades to producitonise, at best. Nuclear fusion is potentially the best bet, but that's been a decade away for the last hundred years. hehe

Hydrogen certainly has a future in various industrial seeings and probably for large-scale transport, but if it's ever going to be a significant proportion of the personal car market it's not likely to happen in my lifetime. By the time it does happen we'll have to have found a solution to the EV charging problem for the masses anyway which will probably make hydrogen a pretty niche market.


I do wonder if we'll eventually see very small HFC range extenders as an optional extra in some EVs.

Obviously this thread will soon be taken over by those that don't believe hydrogen has a future, but it's interesting that Toyota are pushing this. Maybe it's just a marketing ploy, but will be interesting to see if they keep developing it.

Electrolysis of water is a straight forward but energy intensive way of creating hydrogen.
And as going forward we will have renewables making electricity when the grid doesn’t want or need it, it will be diverted to hydrogen creation.
Only problem at the minute is the volume of hydrogen storage available. But even that is being worked on with potential to improve into underground caverns, old oil wells, mines etc

In the short term hydrogen is more usable for infrastructure.

But an EV with around 30kWh / 100 miles + hydrogen range extender is where we need to be.

For many folks (like us) any bev is and always will be 100% useless - as there is no way of charging it.

We live in a little village in the middle of Devon.

I can but imagine what the cost would be to upgrade the local electrical infrastructure in the coming years, especially if we had the leccy, and the holes in the ground, and someone to do the work and somewhere to put the charging box, and someone to wire up the charging box...

Ah, about that!

China's trialing Hydrogen HGVs and building some Hydrogen fuel stations - I hope we see a multitude of substitutes to fossil fuels eventually become established.

Must be a nightmare setting up the compression and rebound damping on a car that gets heavier as it empties its fuel tank.

Quite sad that 15 years after manufacturers showed the feasability of such technologies that we're still being force-fed hybrid/electric vehicles.

Ha, very good!

(I've assumed it's a joke, but for anyone who might scratch their head - it's stored as a liquid so its greater nett mass than airsmile )

I guess it's not a joke, they've been developing a Corolla as well (with the Yaris GR engine)

180 litre tank for half an hour of race pace at Tsukuba is a hefty consumption though, I think that works out to about 5.5/6 litres a lap.

It'll be stored as a gas onboard, not sure about the Yaris in the pic but that's how it's stored on current hydrogen vehicles and the Corolla (using the same engine as this!)

Pretty sure hydrogen needs to be cryogenic temps to be a liquid. You wouldn't develop a tech like that for mainstream use, waste of time and money. Imagine average joe filling up their car and accidentally touching the fuel filler neck afterwards. bye bye fingers! lol

Yep, you were both correct, it is a compressed gas. Only BMW are looking at liquid hydrogen storage.

Bulkhead and blanked off rear windows because the tanks occupy all of the space behind the front two seats.

The consumption rate of burning it in an IC engine is ridiculous, and if you're making hydrogen cleanly then you need loads of power to do it. At least synthetic fuels for motorsport don't need hefty pressure vessels to contain it.

3 of the 4 hydrogen filling stations in or near the M25 are out of action. Even if I couldn't charge at home it'd be a lot easier to charge my EV than traipse to Teddington every time I needed to fill up.

12 hydrogen cars registered in the UK last year vs 190k battery EVs. If it's the way forward how will that chicken/egg situation get resolved?

I know amazing eh?

We do actually have mains gas, sewage, and fibre broadband, much to the surprise of many visiting friends / relatives who have ste broadband in major conurbations.

Ironically I have solar panels on a workshop I rent, and a pleasantly low cost per kwh to boot, but most of the time I work from home...

Hence in the hopefully not completely impossible chance of me buying a new car in X years time, it'll have to be a hybrid - which I imagine HMG will change to the rules to allow, when a bit of reality finally sinks in.

Until then, I'm well happy with my 2009 320d estate.

Jay.

Except for the large % of folk in the UK who would never be able to charge a leccy car, even if we had enough of said leccy, in the right place..

Why not?
There are plenty of rapid charger locations in Devon. Crazy idea I know, but could you not drive the short distance to one and charge up?
