UK Company Riversimple Plans a Fuel-Sipping Hydrogen Car (techienews.co.uk)
TechnoidNash writes: Riversimple has been developing a hydrogen car with the support of a 2 million grant from the Welsh government. The result of their efforts? The Riversimple Rasa. A hydrogen car with a claimed fuel economy of 0.9L/100 km (250 mpg). The Rasa can reach up to 96 km/h (60 mph) and has a range of 483 km (300 miles) on a 1.5 kg tank of hydrogen.
Here it comes, the world's newest hydrogen-powered automobile... there she is... the technicians are attaching the hose... OMG!!! OH, THE HUMANITY!!!
I deny that I have not avoided attaining the opposite of that which I do not want.
Umm, getting a machine to run on pure hydrogen fuel was never a challenge. Supplying the hydrogen to the machine, especially via the user, now that's the challenge.
put in like ten of those fuel canisters in there, armor them up nice and heavy so one exploding won't set off the others, double the engine...serious roadtripmobile. Who cares about finding a refueling station in the next state over when you can make a 2000+ mile roundtrip to the station back home?
A car with the range for highway driving, which is incapable of traveling at highway speeds...
It's got a top speed of 96 km/h, while typically highway speeds here are around 120 km/h with a speed limit of 100... Do you really need a car with almost 500km of range if the anemic top speed effectively limits it to surface streets?
Tiny two-seater with a top speed of 60 MPH? Here in Texas that wouldn't even be considered highway-capable. The speed limit on many of our highways is 75 MPH, and I'm not even sure the majority of drivers stay within that. (I try to, usually, but passing with the Tesla Roadster is quite easy. And fun.)
I see a lot of detractors chiming in on this company and their claims. To an extent that includes myself. Please keep in mind that whatever reality this does or does not work out to be, it is the science being conducted by this company that matters the most and will bleed into the the future as it is fairly obvious this technology has the potential to eventually be viable.
Wait.... Fuck a duck. All this science is probably covered ten miles deep in patents and "intellectual property". Never mind. Can anyone elaborate on how the Welsh government treats such things?

"I'm not much interested in interoperability. I want substitutability. I want to be able to throw your software out."
that is pretty steep.
in 5 years you pay the price of a brand new bmw 5 series and you own shit.
7000€ to own it and 5€ per 1,5 kilos of hydrogen, that what i would call interesting.
0.9L per 100km
483 km range
1.5kg tank
483km/100km * 0.9L = 4.347L
1.5kg/4.347L = 0.345kg/l
Density of liquid hydrogen = 70.8kg/m^3 = 0.0708kg/l
Density of gaseous hydrogen = a whole lot less than liquid hydrogen at any achievable pressure. I think getting to 0.35kg/l would require something like 7000 atmospheres.
So, what do they plan on putting in that 4.347-liter tank that holds 1.5kg of hydrogen? Room-temperature superconducting liquid hydrogen metal? If so, I hope they publish some papers on how they stabilize it. Or maybe they've found a way to make a cubic meter of diamond with a 5-liter void in the middle...
Serious question.
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
they got a grant. good for them
Ahhh my eyes, why do they hurt so much...

Anyone around long enough will remember how stupid the CNG trend was
Umm. LNG is taking off in a big way. Cummins, Caterpillar and all the other diesel manufacturers are pushing dual fuel engines. New emissions regulations are moving marine engines to running LNG in port:

There's been a lot of work on storing and retrieving hydrogen from solid storage over the last couple of decades - so if you don't think of it that way and instead think of it as just a gas bottle the numbers would indeed make zero sense. I think "New Scientist" had had a few good articles on it over the years.
All the busses and most of the taxis run off it where I live. The taxis that do not are hybrid electric cars however.
Hydrogen does directly compete with electric cars and is not competing very well but it is still too early to dismiss it out of hand. Batteries suck a vast amount less than they used to but they are still disappointing.
While very likely that's only a segment of the hydrogen vehicle work. Also don't dismiss it out of hand just because of the sponsor - the first working hybrid car I saw was built for a mining company in 1986. They wanted a crew transport vehicle to operate underground without emissions and also drive above ground where emissions did not matter as much. Full electric wasn't an attractive option because batteries really sucked an incredible amount in 1986.
If only it looked something like the Hindenburg instead of a 21st century Robin Reliant.
For buses where all the operational parameters are known I can see CNG working. Here in New Zealand in the 1980s there was a huge push for CNG with government support and subsidies. The average New Zealand car was, and still is, around 1600 to 2000cc. Not much power and CNG made that worse. I used a company L300 van running CNG. It took longer to fuel, ran a shorter distance on a tank, handled worst due to the extra tank. The L300 was not powerful to start with and there is a lot of hills in Wellington, so you often had to switch to petrol at bottom of a hill or risk stopping halfway up. About 20% of gas stations sold CNG which sounds like a lot until that limited range kicked in and you couldn't find one near by. This was the 80's, no 'app for that'.
Not surprisingly after about 5 years the public had had enough of all the hassles and limitations and stopped installing CNG in vehicles and the 20% of stations selling it rapidly fell to zero again.
Back to hydrogen. Look at the performance and cost curves of batteries, extrapolate over the next 10 year and it is clear EV will out perform IC vehicles in more and more cases. I have used an EV when I was living in China, I loved plugging in at work and never having to visit a gas station. I have electricity at home so I am EV ready, when I can afford one. Where is that hydrogen I would need going to come from if I went down that path? EVs are so simple, is a hydrogen solution going to be able to match that over the long term?
Did you read it? It's nothing but chemistry and physics. Did they invent a new kind of hydrogen in the meantime?
Caterpillar and all the other diesel manufacturers are pushing dual fuel engines.
Of course they are. It is a fairly trivial change to go from gasoline to LNG or even hydrogen. They can adapt the existing designs.
Going form gasoline to electric motors is a whole different game altogether. Instead of a host of mechanical engineers (and almost all engineers in the transportation industry are mechanical engineers), you need a cadre of electrical engineers. This basically means laying off a large percentage of your engineering workforce, many of whom are barely more than glorified autocad draftsmen, and replacing them with electrical engineers. Because this would be a whole new discipline for the manufacturers, they would have all kinds of hell trying to get product to the market, and would have to hire top electrical engineers or risk having the project fail. It would quickly mean higher costs and lower margins for the manufacturers. Why on earth would they sign up for that if they didn't have to. Electric vehicles are great for consumers (although the technology is not quite there yet), and great for electrical engineers (especially power systems engineers), but bad for established companies, and especially bad for mechanical engineers (A typical IC engine vehicle has 10,000 moving parts, of which 98.5% are in the engine, or are related to the IC engine).
People talk about an oil industry conspiracy to kill off electric vehicles, but the reality needs no such complex explanation. The simple truth is that the existing companies are not capable of building cost effective electric equipment, so they don't. It takes an upstart in the industry, like Tesla motors, to come along and force the industry to keep up or die. My prediction is that the electric revolution will kill upwards of 50% of the established auto manufacturers, and a similar effect will be seen in industrial and construction equipment soon thereafter.

GM's last transmission was a $1.3 BILLION development.
In the past I have used the Chinese e-Scooters and found them great fun, and at about USD $400 very practical in China. Unfortunately the performance and quality wouldn't cut it in most first world cities.
A few minutes ago the guys from Gogoro turned up here (a major Tawian factory) showing off their SmartScooter. The guy's English wasn't great but I gather it is about a 6KW motor with a top speed of 95kph. I rode up the street, the performance feels like somewhere between a 125 and 250cc motorcycle. At about USD $3K it looks like a very practical and affordable city vehicle. At that price I think I would buy one tomorrow for my city commute if they sold them back home.
Looking at the shape of that hydrogen car I suspect the SmartScooter has more carrying capacity too. Sorry hydrogen, you are too late to the party, your not fooling anyone around here with your vaporware.
hope you don't have an accident with it anywhere along that chain
Almost the same chain that ordinary gasoline/petrol has at the moment. So it's no less safe, and that well-established infrastructure can cope with the demand and recharge times that meet users current expectations.
fuel cell that is around 60% efficient
That's about 2-3 times as efficient as just burning the fuel to create motive power. The electric motors are likely to be ~95% efficient. That's a huge improvement right there.
Pure electric cars using safe batteries with loads more power that can go 300 miles
The energy density of these 'safe' batteries is way poorer than liquid hydrogen both by volume and weight. It's crazy that half the weight of a 2-ton pure EV is its batteries (with current technology) just to give it a barely acceptable range (followed by several hours to recharge). Obviously research should get that better over time, but it's a got a long way to go to beat hydrogen. A fuel-cell car makes a lot of sense during this transitional period between the dinosaurs and the pure EV of the future - it's a huge improvement in efficiency and pollution but can leverage existing infrastructure.
Your argument seems to be we should ignore this because it's not as good as some imaginary car of the future, rather than we should be interested in this because it's better than the frankly terrible non-imaginary car of the past.
Not surprisingly after about 5 years the public had had enough of all the hassles and limitations and stopped installing CNG in vehicles and the 20% of stations selling it rapidly fell to zero again.
Aside from the buses, My little city has one CNG dispensing station. It already has many more EV charging stations. I've never seen the CNG station in use.

I don't think it's logic or anything like it. It's something visceral. Something that makes reviewers fake problems, and people standing up for their fraud. It's people claiming no infrastructure when its obviously there. Its declaring EVs as fatally flawed when one catches fire, and ignoring that petrol fueled ones do. They hate em.
The shepherds did so well protecting the flock that the sheep no longer believed that wolves existed.
Other wild guesses are just as good as that very wild one. Both options have some promise and some viability - anything more than that is currently fortune telling.
The most likely situation is a mix of technologies.
And in mine it's at every place where fuel is sold due to it being in use for years as the fuel of choice for taxis. Anecdotes are no substitute for a general case. The refineries here have been selling it for decades while the ones in other places have even just been setting fire to it as a waste product.
It's a chicken/egg situation where once there is a market it is commonplace and if there is not it is rare, such as in your city.
LNG isn't CNG isn't LPG.

Whoever wrote this is (willfully or otherwise) ignorant of the driving conditions on UK motorways. Driving at 60mph is basically impossible - you either have to get in the slow line behind the lorries and go slower, or get in the middle or fast lane and drive ~80mph. Yes, the speed limit is technically 70mph. In most part of the country, nobody gives a crap.
So the range is nearly irrelevant; the car is unsuitable for motorway driving so you won't be taking it any distance at all.
I realize they are trying to bring slashdot back to its former glory, but I'm not sure that this is what they had in mind :)
What wild guesses? I have watched EVs for about 40 years now. My father ran a fork truck manufacturing company so I was driving EVs before ICs. I have watched them slowly improve to the point they now compete directly with ICs and I have watched the range double every decade. With the intense focus on EVs I think it safe to extrapolate that the battery capacity will continue to improve and cost will continue to come down and at some point in the next decade EVs will exceed ICs in performance.
Hydrogen cars? Never seen one in real life that was moving.
We have plenty of renewable sources for electricity in Europe, and getting more each day. Sure, the wind doesn't always blow, the sun doesn't always shine and the water doesn't always flow, but it sure does reduce the amount of coal and natural gas required. And fortunately a few countries still have enough intelligence to invest in nuclear power (rather than keeping aging nuclear plants running way past their projected life time, hoping they don't blow up some day).
Anyway, the amount of energy required to simply produce the fuel for a regular ICE car (before burning the fuel!) is about the same as that required to recharge an electric vehicle to drive the same distance. So when you've filled up your gas car, you've already lost the comparison and you haven't even burnt the stuff yet.
I don't have the numbers for hydrogen cars, but I hear most hydrogen is produced from fossil fuels since hydrolysis is way too inefficient to be cost-effective, so it will probably be in the same ball park if not worse. OK, at least it doesn't cause local pollution anymore, but as far as our reliance on fossil fuels is concerned, it's hardly an improvement.
It's crazy that half the weight of a 2-ton pure EV is its batteries (with current technology) just to give it a barely acceptable range (followed by several hours to recharge).
Most owners of electric cars let it charge at home overnight, or at work, and they usually only use a fraction of the available battery capacity. The only time charging time is an issue is when you're making a long trip, and then a Tesla supercharger will fill you up from empty in about an hour. Not several hours.
Some of the smaller, cheaper electric cars do have anemic range (and long charging times), but they are hardly the state of the art. And even they do just fine for many city dwellers who don't need more than that.
One is liquefied, one is compressed.

As Musk explains:
“Hydrogen is an energy storage mechanism. It is not a source of energy. So you have to get that hydrogen from somewhere. if you get that hydrogen from water, so you’re splitting H20, electrolysis is extremely inefficient as an energy process. if you say took a solar panel and use the energy from that to just charge a battery pack directly, compared to try to split water, take the hydrogen, dump the oxygen, compress the hydrogen to an extremely high pressure (or liquefy it) and then put it in a car and run a fuel-cell, it is about half the efficiency, it’s terrible. Why would you do that? It makes no sense.”
Riversimple Rasa? Seriously? Why not be honest and go with Limpwrist Milquetoast?
Nut up, and buy the old Marauder name off of Ford.
So? You cannot really use infrastructure that produces or consumes one to handle the other, even if both types are mostly methane.
Finally! A year of moderation! Ready for 2019?
I've got an EV, and roof mounted solar. For the amount of driving I do (about 200Km a week) an EV is perfect and I make the fuel. There's no transporting, storage or anything. I make the fuel and it goes into the car's battery ready with a full charge any time I need it. Hydrogen is just another way to keep us paying for fuel. If I need to go further than 150Km and there aren't fast charge stations at the destination or along the way, I'll rent a petrol car. Hydrogen is not the future.

Extrapolating over ten years. Generally a very bad move in a changing situation and just asking for ridicule in ten years time.
Wish I had mod points today, parent is a highly insightful post summarizing the situation and outlook perfectly.
Think of the enormous service industry as well, there are millions of people employed in the industry of servicing gasoline cars and trucks, but many of those people will be out of a job with the shift to electric vehicles, as they simply do not require the same high level of maintenance (check out the Tesla 5 year service checklist, it's ridiculous how little maintenance these cars require), and many will face challenges adapting to the new required skill set. Very little motivation from the established industry to change to something so unknown and unpredictable.
