Improvement to the hydrogen fuel cells:

Hyundai NEXO FCEV

“Designed to handle extreme temperature and environments, the NEXO testing has proven that the vehicle is capable of starting after being subject to overnight temperatures of -20 degrees Fahrenheit. NEXO boasts cold start capability within 30 seconds which is an industry-leading achievement and the fuel cell system warms up faster for maximum performance. The NEXO also has excellent cooling performance on steep grades with temperatures exceeding 120 degree Fahrenheit.

Improvements in the air supply system, performance at high altitudes and refueling times, along with overall efficiency and fuel economy put the NEXO in a class all its own. In addition the NEXO has improved power density and durability comparable with a gasoline-powered vehicles.”

Nexo comes also with new features:

Hyundai NEXO FCEV

Blind-spot View Monitor (BVM)
Hyundai’s Blind-spot View Monitor is an industry-first technology. It shows drivers on a center cluster screen the rear and side views of NEXO using cameras while changing lanes in either direction. The system uses wide angle surround view monitors (SVM) on each side of the vehicle to monitor areas that cannot be seen by a traditional rearview mirror. Hyundai is the first automaker to provide drivers video footage from both sides of the vehicle.

Lane Following Assist (LFA) and Highway Driving Assist (HDA)
Lane Following Assist is an all-new technology for Hyundai and it debuts in the NEXO. LFA automatically adjusts steering to help keep NEXO centered in its lane of travel. LFA can keep NEXO centered at speeds between 0 and 90 miles per hour on both highways and city streets. When paired with Hyundai’s Highway Driving Assist (HDA) which utilizes sensors and map data to ensure safe operation as well as automatically adjust speed in limited environments, drivers will be able to traverse long distances with greater ease and improved safety.

Remote Smart Parking Assist (RSPA)
RSPA enables NEXO to autonomously park or retrieve itself from a parking space with or without a driver in the car. The RSPA system can even back a NEXO into a parking spot by itself with a touch of a button from the driver. When faced with any challenging parking scenario, NEXO drivers will be able to park with complete confidence and accuracy.

Did they “improve” the fact that the production of hydrogen is from natural gas, and produces carbon? Did they “improve” the fact that HEVs are only 30% efficient, less efficient than current ICE hybrids? Did they “improve” the fact it costs ~$2 million to build a fuelling station, and it’d take over $1 trillion to build out the infrastructure?

The only reason I can think of that the manufacturers are still stuck on HEVs is they’re stuck in “But we spent so much money!” mode and have blinders on to the fact nobody wants them.

You forgot the most important thing, which is cost to consumers. At $16.50/kg, or 3X gasoline even after factoring in higher FC efficiency, it’s a no brainer why consumers will stay away.

There is potential for H2 cost reduction, as 70% efficient SMR needs under $0.60 of natural gas per kgH2, and a 50kWh/kgH2 electrolyzer needs ~$2 of renewable energy. How much the capital and distribution costs can be reduced with volume is unknown to me.

But you’re right that fuel cost is a big issue. EVs are untouchable in that respect.

The only case for H2 is when all the following hold:
A) ICE is forcefully removed as an option
B) The EV has no fixed overnight parking spot
C) It’s much more expensive to implement many streetside chargers than an H2 station
D) H2 cars cost far less than EVs

If even one is false, EV/PHEV wins.

If H needs $2 for 50 kWh, battery would need $0.50 for the same. There is room for improvement in selling H, but I don’t see it coming anywhere near gasoline. All the projections depend on electricity that will be almost free (or less than free), and that just won’t materialize when they can’t scale in the first place.

Now if they ban ICE cars outright, H might have a place. But at a cost far more than gasoline, people will not take up on it. Realistically, that will never happen.

Aluminum/surplus renewable electricity/ hydrogen cycle has not escaped Germany or the US Military, For your and others elucidation, as follows:

That’s exactly what is happening in Germany although in their case it appears to be more a case of using the smelter as a peaker plant.

please update your self. US Military runs tanks on H2! Do the research. Start here?
https://www.newscientist.com/…/2142693-nano-aluminium-offers-fuel-cells-on-dema…

I enjoyed watching the new car drive along the highways and byways. Probably the driver driving 100 miles to find the next WORKING Hydrogen Dispensery.

Sarcasm? Uninformed American? Your own Military have “invented” an aluminum power that will provide H2 for their tanks in the future! Can be air dropped to them too! read all about it here:

Looking forward to seeing a side-by-side comparison of Hyundai Kona vs Nexo.

Kona EV: 160 kW (201 HP) motor and 250+ mile range
Nexo FCV: 120 kW (160 HP) motor and 370 mile range when filled to maximum pressure (not available at of H2 filling locations)

I’ll leave it to InsideEVs to do a similar spec charge to that above showing 0…60 mph times and dimensions, etc.

In the mean time … for reference:
https://insideevs.com/hyundai-kona-electric-250-miles-range/

FYI: I’m an Kia Soul EV driver that managed to go 30,000+ miles in 12 months using 81 kW motor and 27 kWh pack offering ~93 miles range (EPA measured). BTW: have driven over 225 milies on single charge … and driven between Montana and Washington states without stopping to charge in Idaho.

> between Montana and Washington states without stopping to charge in Idaho

About 75 miles across on the I-90?

A bit farther between usable charging points …
ie: over 100 miles. 😉

“According to Dr. Woong-chul Yang, Vice Chairman, Hyundai Motor Company “Hydrogen energy is the key to building a more sustainable society“, which means that they will not leave the FCEV segment any time soon.”

Hydrogen is not a source of energy anymore than a battery is a source of energy. Hydrogen is a means of energy storage, and a rather inefficient one at that.

Adding electric motors, batteries but forgetting the plug…*sigh*…

It’s designed to take us into the 21st century, but still keep us dependent on the gas station. In this case, literally a gas station.

*sigh*

You can buy a hydrogen generator for yourself that use electricity to make hydrogen.
It is a process with energy losses in several steps, but it can be clean anyway.
We need companies like this that can spend millions on research and improve, and make fuel cells cheaper.
There will be areas of use, where this may be a smart solutions.

Even if this car costs $20K, less than comparable gasoline cars, would you be willing to pay 3X gasoline price to fuel at sporadic locations? I doubt anyone would drive car like this that must pay equivalent of less than 10 MPG.

US Military designs a nano aluminum powder to fuel tanks – can be air dropped? is very light, large amounts can be carried? Earl! you are chewing hard, bit on the wrong cigar?

John Doe said:

“You can buy a hydrogen generator for yourself that use electricity to make hydrogen.”

A Simple Fuel home H2 generation/ storage/ dispensing unit costs $250,000… or more. Cheap at the price, right? 😉 But hey, at least Simple Fuel actually gave us its price. Other companies don’t even do that!

https://insideevs.com/ivys-simple-fuel-hydrogen-station/

“It is a process with energy losses in several steps, but it can be clean anyway.”

You could say the same about a steam engine car which burns biofuel. Just because it’s “clean” doesn’t mean it’s at all practical, nor competitive with either gasmobiles or battery-electric vehicles.

“We need companies like this that can spend millions on research and improve, and make fuel cells cheaper.”

No, we need to take those millions and use them for a tech which is actually useful, such as improving EV batteries. We need to stop wasting money on supporting the “hydrogen economy” hoax.

“There will be areas of use, where this may be a smart solutions.”

Sure, there are niche applications where hydrogen fuel and fuel cells make sense; for example, in spacecraft. But not in powering wheeled vehicles.

The hydrogen boondoggle vehicles will not go away until state governments no longer count them as zero emission vehicles.

Compared to the less than $100 power cable if I just want to plug into the wall or less than $600 for a charging station.

How cheap can I get that hydrogen station with separator/chiller/compressor again?

Not hard to believe that they can improve the poor crippled fool cell car. I mean, there’s so much room for improvement for those overpriced science fair experiments!

But too bad for fool cell fanboys that improving the hydrogen molecule isn’t possible, because that is what will forever keep hydrogen-powered cars from being popular or successful.

Don’t worry old man. You won’t being seeing streets full of HFCV’s anytime soon, so stop getting your knickers in a twist every time the word hydrogen is mentioned around here.

Never understand anyone being so convinced that the technology cannot succeed, and yet be so insecure about it.

Take your meds!

Took my meds, just for you, and yes! I am another old fart! Do your research sonny! Start here:
copy and paste this into Google:
Military uses aluminum powder for H2 production
Have fun!

Tell China quick:

Title: “Prospects of fuel-cell electric vehicles boosted with Chinese backing”

“For the last 2–3 years, the Chinese government has put great emphasis on the roll-out of fuel cell mobility in China, shifting the public support focus slightly away from BEV to FCEV”

Search the title and you can find this excellent article. The fact that China is going all in on fuel cells is going to cause BEV fanbois/H2 haters to lose their marbles. Fun times!

How much does H cost retail in China? I suspect it’s far more than gasoline. If Chinese (like idiot CA politicians) want to waste tax money to subsidize ridiculously high priced fuel, that’s not our concern.

All you FC fanbois get back to me when retail kg of H is less than gallon of gasoline. Until then, it’s just lots of hot air.

The Chinese will do this this because the government like central control. If they could they would prefer that hydrogen is what their industry depends on as they can control the production.

The reason they are pushing BEV is the pollution problem is even a more pressing problem to handle, but realize the Chinese are not pushing hydrogen because is it better than BEV they are pushing what they can because they want control.

New username Waserstoffer is a shill for the H2 industry as his linked username shows us and his very username in German means Hydrogen.

So we continue to get trolled by H2 industry people here.

I for one would like to be “trolled” by the hydrogen industry more. More choices for cars, better efficiency, longer ranges, more filling stations, more cost effective, cheaper fuel, yada yada.

better efficiency– bullcrap
more cost effective — bullcrap
cheaper fuel — bullcrap

Maybe you’re using sarc but the rest of your post is reasonable. So…

Improvements in many categories but Hyundai remains mum on the biggest problem: cost. So how much does it cost to produce one of these new Hyundai HFCVs, what sort of maintenance cost does it take to keep these hydrogen marvels safe and how is the 70% reduction in fuel cost that’s needed to make it competitive with gasoline and plug-ins going to be achieved?

Hyundai is wasting their time….which would not be a problem if they weren’t wasting our time as well.

Instead of spending time and resources on a completely lost cause, they should be stepping up their EV game and produce the Ioniq EV and the Kona EV in meaningful numbers instead of compliance production.

Maybe they could even introduce new EV cars as well so that the market is covered better (station wagon, mid-sized sedan…etc).

Stop the hydrogen bullsh** Hyundai and give us more/better EVs !s

Hydrogen has had a slow start but really the question is whether the fuel cell stack can decrease in price faster than batteries can. Looking at raw material prices for batteries it doesn’t look good but hopefully we’ll get better batteries soon.
The hydrogen vs battery battle sure isn’t over yet!

No, the real question is the cost of producing carbon free hydrogen and the cost of building those expensive fueling stations. My fueling station is in my garage so I can fuel up my Tesla model S every night cheaply and easily.

Look the hydrogen stack could be free and it still is a dead-end.

BEVs can use the power directly from *ANY* electrical source, hydrogen cars need too much processing to produce the fuel. The best conversion I can so far is 50% efficient and then you still have to spend energy chilling and compressing the hydrogen. You waste 2/3 of the energy getting the fuel ready for use.

Worse, with an BEV I can charge it up every single day to 80-100% with a simple cable at home, I can’t do that with hydrogen. I always have to pay someone else.
