How does a hydrogen filling station work?

There’ s a cool sensation in the palm of the hand. It comes from holding the nozzle attached to the fuel dispenser at the new hydrogen filling station. We are in Wiener Neudorf, the site of one of Austria’s five hydrogen refueling stations. Even though it looks like an ordinary gas station at first glance, there are quite a few things here that make it different.
The hydrogen filling station itself is a high-tech facility. Starting already with the storage. The gas awaits customers in racks of cylinders or an above-ground fuel storage tank. Hydrogen is very amenable to compression, so there’s space here to fully fuel around 60 vehicles.
In order to get a similar amount of energy into a hydrogen vehicle as with gasoline or diesel, the fuelling process requires much higher pressure than is needed for storage. This is why hydrogen filling stations have compressors to reduce the volume of the hydrogen by an additional 94%.
The highly compressed fuel undergoes minimal expansion during the fuelling process at the pump. And when hydrogen expands, it warms up. To ensure that temperatures don’t rise too much when refueling, the hydrogen is cooled to minus 40°C before it reaches the nozzle.
The fuelling process is monitored electronically. If all of the measurements are normal, a full tank takes around 3 minutes. 700 bar pressure in the tank means the end of the process. After all, the hydrogen then has an effective volume of 55 cubic meters, equivalent to around 250 full bath tubs.

Fuel prices “comparable” to gasoline? Where does that happen?

[@greeneyeddg]

How long before hydrogen fueling stations become the norm? Are there franchise opportunities, and would extreme cold weather make such a venture more or less viable? A business opportunity where snowmobiling is popular has me wondering if hydrogen-powered, quiet snowmobile rentals and a hydrogen refueling station would be a solid investment?

[@omv]

Hello greeneyeddg. We cannot judge if a h2-powered snowmobile business would be economically feasible but the advantages from hydrogen as a source of mobility are quite obvious: -) No local CO2 and NOx emissions -) Hydrogen vehicles offer long-distance electro mobility with familiar driving comfort -) Proven technology suitable for mass production -) Fueling with hydrogen is safe, efficient, odor-free and takes around four minutes (for cars) -) Fuel costs and range are comparable to conventional vehicles Regarding your question concerning temperature. This is no issue at all as there are hydrogen fueling stations from California to the northern part of Norway.

[@m43_felix]

Would it be possible to produce the H2-gas right next to the gas station ?

[@omv]

Hi. Producing hydrogen is a very complex procedure that is ideally embedded in a refinery/industrial process. All the best, your OMV Social Media Team

[@chisaomusician7752]

Can't wait to buy my Hyperion XP-1

[@thesixland]

I would like to ask what the price of hydrogen will be in the market?

[@omv]

The price of hydrogen varies depending on the method of production, the source of energy, and the market conditions.

[@thesixland]

@omv But the price needs to be cheaper to compare with electric cars.

[@sheikhfadhilaljahdhamy6751]

What should i do when i want to start a work of hydrogen filling station?

[@omv]

That depends on the region/country and the specific regulations.

[@patrickemery5077]

First of all is this for a fuel cell or a hydrogen engine? Second is that it shouldn't be too hard to make your own station at home. Just have the cooling system and other electrical necessities be solar powered. Easier said than done but if someone said that I can't do it I'm gonna try, even if it blows me up.

[@omv]

Hello! Our hydrogen car in the videi is a fuel cell powered Toyota Mirai - nowadays most OEMs develop H2 in this application. Considering the learnings frum running our H2 filling station network (eg. running the H2 supply logistic, or handling of the 700 bar compressors) we would definitely not recommend trying to build a home station on your own though. Safety first! :)

[@Badkhela]

Why in the f would you do this. 🤪

[@Warlok708]

@@Badkhela fr, you gain nothing and now you have to worry about your car blowing up when you hit potholes

[@wakamoli8248]

At 700 bars you are talking about having equipment to handle over 10,000 psi and not only that, you also have potential leaks when you let pressure drop below 200 bars. Again there are more to it than just plumbing, like having sensors and auto-valves to shut down to prevent fire or explosion.

[@markp8295]

Secondly, hydrogen tanks are not completely harmless. Then mixes with the air rapidly part you mention is marketing speak for explode.

[@jmitterii2]

Nope. Science speak. You can see an example H2 tank which was ruptured and ignited vs gasoline vehicle's tank the same. It jets the H2 fuel straight up. The gasoline vehicle literally roasts. kzbin.info/www/bejne/f5zRq3h3qJhnqJI

[@SharhbiniRauf]

Electrolysis on refueling station, water come by pipe from local water company.

[@NuVids2025]

Ill buy it. Atleast it wont explode when wet! lol

[@LionheartLivin]

The answer: it very often doesn't This is a PSA: Owning a hydrogen car has been the worst car ownership experience in my life: stations are down OFTEN, when I call to customer service and they tell me they work and have enough hydrogen in them I often go there and there's no hydrogen or it doesn't work. And I live in northern CA where we have the most hydrogen stations. PLEASE FOR THE LOVE OF GOD UNTIL THEY RECTIFY THIS HORRIFIC FUELING EXPERIENCE DO NOT, DO NOT BUY a hydrogen car. Just get ANYTHING else

[@WeebRemover4500]

ok so, can you just pull up to one of these gas stations and dump 100L of hydrogen into a garbage bag and drive off without raising any suspicion? would be really cool.

[@Woody78489]

Notice how all these stations are surrounded by thick concrete? I’ll stick to gas or electric and avoid the explosions

[@omv]

Hi P, hydrogen vehicles of the latest generation have already covered many millions of kilometers worldwide in the last few years under everyday conditions. Due to their construction, hydrogen pressure tanks are much more resistant than conventional fuel tanks. The risk of explosion of a hydrogen tank is extremely low. Since hydrogen is under very high pressure (700 times the air pressure) and about 14 times lighter than air, it rises very quickly and there is therefore no possibility that something from the outside (air, oxygen) flows into the tank and it thus an explosion could occur.

[@BrainHurricanes]

@@omv There is video's to find on youtube about tyres and high pressure air tanks exploding. Exploding in the sense of releasing all pressure at once, not an ignition. How is a hydrogen tank different or made more safely ? Thanks.

[@omv]

As stated beforehand, due to their construction, hydrogen pressure tanks are much more resistant than conventional fuel tanks. The risk of explosion of a hydrogen tank is extremely low. Even when a hydrogen storage tank ruptures and assuming a leak ignites, a hydrogen flame tends to burn out, within 90 seconds without huge damages to the vehicle and his passengers.

[@Woody78489]

@@omv yeah I’ll pass. If there wasn’t a major risk they wouldn’t be surrounding the area with massive concrete blocks. Hydrogen is a terrible fuel choice anyway it’s beyond dirty with the current method of production. Electricity with solar and wind and tidal is the future. Even hydrogen cars suck the nicest and most expensive the Toyota Mira Is a giant pile of garbage and is 10 years behind a Tesla in every possible way.

[@BrainHurricanes]

@@omv Thanks I fully understood your first statement. I'll ask different. I would like a compair between a high pressure air tank to the hydrogen tank. I think an air tank is just regular steel, but I'm not sure. How is your tank stronger, how is it build, what material ? Thank you.

[@markp8295]

1:10 You say when hydrogen expands it warms up. This is wrong. Basic gas laws (PVT). During compression it heats up. During expansion it cools down.

[@omv]

The majority of known gases cool upon expansion and heat up during compression. These gases include carbon dioxide and air. In these cases the Joule-Thomson coefficient is positive (at room temperature). In contrast, certain gases such as hydrogen and helium behave in the opposite way: They heat up when expanding and cool down during compression and so they have a negative Joule-Thomson coefficient. Whether a certain gas cools or heats when expanding depends on the inversion temperature of the respective gas and on whether energy is dissipated at the same time in the form of mechanical work or not. In addition to the Joule-Thomson coefficient (for the ambient temperature), the complete thermodynamic system should always be taken into account for the actual change in temperature.

[@edward3709]

lol u so dumb get outta here and educate urself

[@jmitterii2]

PVT is for ideal gas which takes the assumption that 1. We can ignore the volume taken up by the imaginary ideal gas molecules 2.~2. The gas molecules do not attract or repel each other. For H2 at high pressures make for number 2 to become a huge factor and as it relates to number 1. en.wikipedia.org/wiki/Joule%E2%80%93Thomson_effect www.khanacademy.org/science/chemistry/gases-and-kinetic-molecular-theory/non-ideal-gas-behavior/a/non-ideal-behavior-of-gases en.wikipedia.org/wiki/Joule%E2%80%93Thomson_effect

[@squdardt.9719]

Mark Pearce i think she meant when hydrogen warms up, it expands.

[@westsailsmusic]

So the tank is pressurized to 10,000psi? No thanks, I’ll just keep fueling my Tesla at home while I sleep or at work. At least I know the energy is coming from solar power.

[@edwardjonese]

great method for trucking haha.

[@TheRedkid20]

This is the future along with hydrogen fusion and fission not EV

[@EnglishLearnBible]

and expensive. if it is so great are you going to pay for it.

[@シャンパ-f5k]

WHERE DOES HYDROGEN COME FROM? Are we making hydrogen cleanly and environmentally?

[@omv]

Dear Mr. Wang, OMV is obtaining H2 for the hydrogen filling stations from external suppliers. Today, hydrogen is coming from fossil sources to overcome the hen-egg challenge. OMV is evaluating and working on green hydrogen projects to assess the future impact like in our wind-to-hydrogen project (www.omv.com/en/blog/renewable-energy-lets-store-it).

[@Eve-luci]

Hydrogen is the most abundant resource in the universe. No worries

[@Chris-ie9os]

@@Eve-luci ..... it's the energy required to obtain the H2 that's the problem... there is no free H2 on earth and you need to use ~100kWh to get ~50kWh of H2. It's just a really... really inefficient battery.

this sounds like BS

[@HeadNtheClouds]

Hmmmm mmm........ completely harmless you say? It is highly combustible & I can see people using this hydrogen to make explosives, also if it is in a high speed high impact collision, will it not explode before it can vent the “harmless gasses” . A nuclear car, wow! That sucks!

[@omv]

We have been using a proven and reliable technology for years with high safety standards on our filling stations. There are several hundred hydrogen filling stations in use worldwide without any technical issues. Hydrogen as a form of mobility is new, but the technology behind it is manageable. Otherwise the authorities would not have granted us a license. This statement is only valid if the hydrogen pump is used according to given terms.

[@edward3709]

not like gas is much safer

[@jmitterii2]

Demonstration below gasoline vs H2 vehicle. Tell me which looks more dangerous. And Lithium battery vehicles are even worse than gasoline vehicles, some demonstrations and examples recently below the first. kzbin.info/www/bejne/f5zRq3h3qJhnqJI kzbin.info/www/bejne/imS1f3yJm9yUaqc

@@jmitterii2 Don't hygrogen vehicles have lithium battery's tho? On a smaller scale

Not all of them. The Toyota Mirai uses NiMH, like the Toyota Prius. Energy density isn't that important, if you need only about 1.6 kWh.
