Are hydrogen cars greener than electric cars? Are hydrogen cars the best mobility alternative for the future? They don’t emit CO2 during the driving journey – does this mean they’re not polluting? Find out the basics about hydrogen-powered cars and what’s the best option to protect the environment today.

How Hydrogen And Electric Cars Work
A hydrogen fuel cell car has a hydrogen tank that feeds a fuel cell with high pressured hydrogen gas that’ll mix with oxygen. This mix starts an electrochemical reaction that produces electricity to power the electric motor. This means hydrogen cars have characteristics of both electric cars (due to the use of electric energy and motor) and conventional petrol cars (because of the tank). However, they represent a unique share of the transportation market and they’re also called FCVs (Fuel Cell Vehicles) or FCEVs (Full Cell Electric Vehicles).

Fuel cells are the main component of hydrogen-powered cars. Think of them as the maestro of all the processes happening inside the car so that it has the energy to move. Long story short, fuel cells turn the stored hydrogen gas (by mixing it with oxygen) into electricity. This electricity is then used to power an electric motor to propel the vehicle, without any toxic tailpipe emissions. In fact, the only by-product of the whole process is water and heat, as the result of the connection of hydrogen and oxygen atoms that forms H20 molecules. I know – it seems perfect, right?

On the other hand, electric vehicles (EVs), are powered by electric motors that pull current from a rechargeable battery or other portable sources of electricity. Once they are moving, there’s no chemical reaction happening either, only an electric one thanks to the power batteries were previously charged with. But which one is more ecological and sustainable? Electrical cars or hydrogen cars? Before drawing into final conclusions let’s first take a look at the most important characteristics of each type of vehicle.

Hydrogen Cars Vs Electric Cars: Driving Range
Hyundai Nexo (hydrogen powered) can travel around 330 miles or 550 km, which is around the same as the electric Tesla Model S, the best of its kind. Nonetheless, it’s hard to accurately tell the driving range of these cars. It depends on a number of metrics such as the number of passengers the car is taking, if the air-con is on or off, whether the car is on a high-road or stuck in the city center traffic, the type of vehicle itself… This is why different people have been reporting different experiences, due to their unique mix of all these variables. However, as hydrogen cars densely pack their energy storage, they’re usually able to achieve longer distances. While most fully electric vehicles can travel between 100-200 miles on a single charge, hydrogen ones can get to 300 miles, according to AutomotiveTechnologies.

Hydrogen Cars Vs Electric Cars: Available Power/ReFuelling Stations
The number of power stations for EV is growing every day and there were 20,000 electric charging stations in the United States by December 2018. A big number when compared to the less than 45 hydrogen refilling stations in the US, most of them in the California area, according to the US Department of Energy. Indeed, the infrastructure, supply, and the technology of hydrogen cars are still years behind electric vehicles.

Hydrogen Cars Vs Electric Cars: Powering/Refuelling Time
The amount of time it takes to pump hydrogen into the tank is way more interesting (5 to 10 minutes, just like any petrol car) than the one from electric cars. While Tesla’s fast chargers (with 120 kW) give batteries 80% power in half an hour, the BMW i3 or the Nissan Leaf can take around 4 or 8 hours, respectively, to get fully charged. In the end, the time electric cars take to power depends obviously on the charging station and the type of charging connector. But whatever the combination is, and even with Tesla’s most recent V3 supercharger that’s still in beta testing in San Francisco, this is a clear win for the hydrogen car – all because of 1kg of hydrogen storing 236 times more energy than 1 kilogram of lithium-ion batteries.

The Real Problem: Getting Hydrogen
natural gas pipeline hydrogen cars

Although hydrogen is the most common element in the universe, it doesn’t exist in its pure form in the Blue Planet. This means that if we wish to use it as fuel for our cars, we need to produce it out of other compounds like water, natural gas or other fossil fuels, or biomass. And for this, energy needs to be used and environmental and economic costs enter the equation.

In one hand, we can get hydrogen in a clean way by reversing the electrolysis process of water. The problem is that this process of separating H20 molecules to get the hydrogen spends a high amount of energy, making it a very expensive process. However, if this energy is able to come from renewable energy sources like the sun or the wind, the net energy cycle can get very carbon low and the process turns more environmentally-friendly. Yet, another situation is the efficiency of the process, that’s only 75% efficient and allows for 25% of electricity loses.

This is why most today most hydrogen fuel is obtained is by the process of natural gas reforming, which is less expensive than electrolysis. The downside is that harmful by-products such as carbon dioxide and carbon monoxide are produced in the process, contributing to global warming. Furthermore, and although they’re becoming less frequent, methane leaks while extracting natural gas are not uncommon. And these molecules are not only 86 times worse than CO2, being responsible for around 25% of the global GHG emissions. The process of extracting natural gas – fracking – usually also has a significant environmental impact and can harm ecosystems, biodiversity, contaminate waters and cause minor earthquakes.

Some Benefits Of Hydrogen Powered Cars
hydrogen cars fuel station

Cars with hydrogen fuel cells instead of the typical lithium-ion batteries from electric cars offer an attractive value proposition that seems to get rid of the problem of the end of the lithium batteries life cycle. This is a plus as for now, at a time when there’s still some uncertainty about the future of these batteries (from cars, but also from solar panels, cellphones and others) once they no longer serve their main purpose. They’re hard to recycle and some projects are being developed to reuse them as back up generators in urban buildings like hospitals.

As well, driving without any polluting emissions (as would happen if we considering renewable energy grids are growing worldwide with decarbonization) with the plus of being quickly refueled in 5-10 min compared to the best case scenario of 40 minutes charging or the most common scenario of 3-6 hours charging in electric cars, is an unquestionable win for the hydrogen mobility movement too.

Some studies also show the hydrogen economy has the potential to decrease global CO2eq emissions between 0 and 27%. This potential can be met once 1) methane leakages from natural gas are relatively low, 2) methane cracking is employed to produce hydrogen, and 3) a hydrogen fuel cell is applied.

Electric Cars Vs Hydrogen Cars – Which Is More Sustainable?
electric hydrogen sustainability

Despite the benefits mentioned above, most hydrogen today (95% the US) is produced by the process of methane reforming. This tears apart all the potential of hydrogen-powered vehicles as a solution to fight climate change because of the carbon monoxide and dioxide that are generated in the process. As well, the need to use natural gas (a fossil fuel) that might escape during the extraction and transportation (via pipelines) phase isn’t very convincing either. Even if the methane cracking process is improved (and efforts aren’t turning that way) it isn’t likely to be a long term solution.

Yet, as technology develops, perhaps the water electrolysis process of getting hydrogen can be improved and further used as the process gets more efficient. Because the fact that hydrogen cars mean using energy twice (to make hydrogen and then using it to power vehicles) while electric cars can use the energy from the grid straight away is a strong argument in favor of electric cars. All because after converting electricity into hydrogen and back to electricity might involve energy loses up to 45% (including compressing it into a liquid and storing it), making it a not very efficient process.

However, while new methods of producing hydrogen are being developed, such as the proton exchange membrane, which, according to scientists, might get to an 86% efficiency, we need to wait and see what happens. Using the extra energy supply for hydrogen production and creating some hybrid version of hydrogen-lithium-ion cars can also be something, once more studies come out clarifying whether this surplus energy is more efficient to use in dams (not considering their other impacts) or producing hydrogen. As for today, electric cars are a more accessible vehicle – regarding the different types of cars and charging points. They include more efficient processes compared to hydrogen-powered cars and if their lithium batteries are re-used to meet different ends they’re liking to stay a more sustainable solution, at least over the next few years.

Is producing hydrogen expensive?
The cost of hydrogen production is an important issue. Hydrogen produced by steam reformation costs approximately three times the cost of natural gas per unit of energy produced. This means that if natural gas costs $6/million BTU, then hydrogen will be $18/million BTU.

Fill Your Hydrogen Car At Home? Only If You Are A Bond Villain
Filling up a hydrogen car at home would require about a million dollars of equipment and a three-car garage sized space for it. Or you could just plug an electric car into the wall.

ByMichael BarnardPublishedJune 13, 2017
45 Comments
Since children can generate hydrogen for science fairs using nine-volt batteries, it should be easy for adults to generate it to fill their fuel cell cars at home, right? Not so fast. For very rich people with a taste for needlessly convoluted solutions it might make sense, but not for anyone else.

Let’s break this down.

Can you generate hydrogen at home? Yes, it’s possible to generate hydrogen in a science fair kind of way by electrolysing water. A liter of water will get you about 111 grams of hydrogen if you can capture it all. You would probably need one of these industrial electrolysis units to actually get pure enough hydrogen for your car. That’s one parking space in your garage gone.

A kilogram of hydrogen is the fuel cell car equivalent to a gallon of gas. The Mirai holds five kilograms. Getting enough hydrogen would require electrolyzing 45 liters or about 12 gallons of water to get enough hydrogen to fill the tank. That’s very reasonable. It would take about 167 KWH of electricity for the basic electrolysis so it would cost about $20 USD at 12 cents per KWH (the US average).

So far so good.

The volume is a problem though. Those five kilograms of hydrogen as a room temperature gas would have a volume of 6,175 liters. That’s about 6 cubic meters or about 212 cubic feet. You would need a big honking hydrogen storage tank attached to your science fair project. There goes another parking spot.

Then you would need to get it into your car. That requires both compressing it and cooling it. That’s an entire process in and of itself with its own set of machinery and automated controls.

Filling a Toyota Mirai tank to get full range requires H70 compression which is 700 bar or 70 MPa. A bar is a unit of pressure that equates to air at sea level, so you are looking at 700 atmospheres of pressure, which is quite a bit above most home compressors. They tend to tap out around 14 atmospheres.

There’s there’s the small pair of problems of hydrogen molecules both being incredibly tiny and highly flammable. The first part means that you have to manufacture all of this equipment to incredibly tight tolerances. Home compressors need not apply because they work with that incredibly thick substance we call air. The second means that you need to have negative pressure back ups and exhausts to the outside built into the system as well or there’s a good chance of having a fair amount of flammable gas in your garage.

A Toyota Mirai needs to know exactly what pressure and temperature of hydrogen it is getting so it can safely receive the right amount of hydrogen. This requires computer interlocks, otherwise you would have troubles up to and including blowing a gasket on 700 atmospheres of pressure and filling your garage with flammable hydrogen. You’d end up with something that looks like this. There goes a third parking spot in your garage.

The pumping, cooling and computer chunks of all of this are why H70 hydrogen fueling stations cost a minimum of $500,000 USD. And they don’t make the hydrogen, they get it delivered.

So could you generate hydrogen at home to fill your car?

Sure. If you have about a million US to spend on it, a three-car garage just for the hydrogen processing facilities and it’s far enough way from the house and neighbors that the sound of pumps capable of creating 700 atmospheres of pressure doesn’t cause problems. If you are rich enough to consider this, you can probably afford a few acres. Maybe you don’t even mind walking a couple of minutes through your grounds to get to your isolated garage.

Or you could get a just get a battery electric car and spend a couple of hundred bucks to have an outlet installed for it to plug into. And since the biggest electric car battery available is 100 KWH with about the same range as the Mirai (and much better performance), it would only cost about $12 to fill it up.

4 Ways to Make Hydrogen Gas at Home or in the Lab
This entry was posted on April 12, 2020 by Anne Helmenstine (updated on January 4, 2021)
Electrolysis of water is one easy way to make hydrogen gas.
Electrolysis of water is one easy way to make hydrogen gas. (Wikihow/CC BY-NC-SA 3.0)
It’s easy to make hydrogen gas at home or in a lab using common chemicals and everyday materials. Once you have the gas, you can use it for a variety of interesting science projects. Of course, you’re not “making” hydrogen, since it’s an element. It is produced by chemical reactions that release it. Here’s how to make hydrogen safely.

Make Hydrogen Gas – Method 1
The electrolysis of water (H2O) is one of the easiest way to make hydrogen gas. Electrolysis breaks the water into hydrogen gas and oxygen gas. So, you can collect impure oxygen using this method, too.

Materials

Only basic materials are needed for this method:

Water
9-volt Battery
2 Paperclips (or wire)
Container filled with water
Procedure

Unbend the paperclips and connect one to each terminal of the battery.
Place the other ends, not touching, into a container of water. Congratulations! You have electrolysis.
You’ll see bubbles coming off both wires. The one with more bubbles is giving off pure hydrogen. The other bubbles are impure oxygen. You can test which gas is hydrogen by holding a lit match or lighter over the container. The hydrogen bubbles will burn; the oxygen bubbles will not burn.
Once you’ve identified the hydrogen source, you can collect it. Collect the hydrogen gas by inverting a water-filled tube or jar over the wire producing the hydrogen gas. The reason you want water in the container is so you can collect hydrogen without obtaining air. Air contains 20% oxygen, which you want to keep out of the container in order to keep it from becoming dangerously flammable. Don’t collect the gas coming off both wires into the same container, since this is a mix of hydrogen and oxygen and is flammable. If you wish, you can used a second container with water to collect the impure oxygen.
Disconnect the battery. Stopper or cap the container of water and gas before turning it rightside-up. Label your container.
Make Hydrogen Gas – Method 2
While electrolysis is a good method to get hydrogen, there are two improvements that greatly improve yield. The first is to use pencil “lead” (pure graphite) as electrodes. The second tip is to add a pinch of salt to the water to serve as an electrolyte.

Graphite makes good electrodes because it is electrically neutral and won’t dissolve during electrolysis. Salt dissociates into its ions in water and increases the current flow, boosting the electrolysis reaction.

Materials

Aside from the addition of pencils and salt, the significant change is that you have more options for the battery.

2 Pencils
Salt (sodium chloride or Epsom salt)
Cardboard
Water
Battery (could go as low as 1.5V, since there is an electrolyte)
2 Paperclips or pieces of electrical wire
Container filled with water
Procedure

Remove the erasers and metal caps from the pencils and sharpen both ends to expose the pencil lead.
Add a pinch of salt to the container of water.
Use the cardboard to support the pencils in the salt water. Place the cardboard over your container of water. Insert the pencils through the cardboard so that the lead is submerged in the liquid, but not touching the bottom or side of the container.
Attach a wire to each pencil. Connect each wire to a battery terminal.
Collect the gas as before, in a container that has been filled with water.
Make Hydrogen Gas – Method 3
Chemical reactions often release hydrogen gas. One reaction is between zinc and hydrochloric acid to produce zinc chloride and hydrogen gas:

Zn (s) + 2HCl (l) → ZnCl2 (l)+ H2 (g)

Most metals react with acid to release hydrogen, so feel free to substitute iron or aluminum if it’s more readily available. Collecting the gas is a bit trickier because of the acid. It’s a good idea to perform this reaction within a fume hood and to wear goggles and gloves. One method is to invert a glass container of acid over the metal so the gas displaces the liquid. It’s much safer to invert an empty collection bottle over the reaction and let hydrogen displace air. Hydrogen is lighter than air and will rise. The collection bottle will contain some air (and oxygen) at the end of the process.

Materials and Procedure

Hydrochloric acid or muriatic acid
Zinc granules (or strips of aluminum or iron filings)
Mixing the acid and metal immediately releases bubbles of hydrogen gas. Be careful to avoid touching the acid. Also, expect heat production by this exothermic reaction.

Make Hydrogen Gas – Method 4
Strong bases also react vigorously with many metals. Sodium hydroxide (NaOH) and potassium hydroxide (KOH) both contain the element hydrogen and release hydrogen gas. For example, aluminum and sodium hydroxide react to produce hydrogen and sodium aluminate:

2Al (s) + 6NaOH (aq) → 3H2 (g) + 2Na3AlO3 (aq)

Materials

Sodium hydroxide (commonly sold as a drain cleaner)
Aluminum (often included in drain cleaners or you can use aluminum foil)
Water
Procedure

Place drain cleaner and aluminum in a glass dish. Don’t use metal or plastic because the drain cleaner could react with the metal. Heat produced by the reaction could damage plastic.
Fill a glass container with water to collect the hydrogen gas.
Invert the container of water over the pile of chemicals and collect the hydrogen gas.
Safety Information
Familiarize yourself with the safety information for any chemicals you may use. In particular, hydrochloric acid (a strong acid) and sodium hydroxide (a strong base) are caustic and can cause chemical burns. If you use these chemicals, be sure to wear gloves, safety glasses, and other protective gear.
Store hydrogen gas away from open flames, heat, and ignition sources.
Be aware that mixing hydrogen gas with oxygen or air (which contains oxygen) increases its flammability because oxygen is an oxidizer.
If you enjoyed making hydrogen gas and would like to try a similar project, try making chlorine gas.
