Filling up a hydrogen fuel cell car is not as complicated as it may seem. In fact, it's just as easy as filling up a gasoline-powered car and doesn't take much longer. The process is also relatively dirt-free. To fill up your hydrogen fuel cell car, you'll need to locate a hydrogen fueling station, which you can do via an alternative fuel station locator website or app. Once you're at the station, the steps are similar to filling up a regular car: insert your credit card, attach the nozzle to your vehicle's fuel receptacle, and let the hydrogen flow in automatically. The nozzle will communicate with your car to determine how much fuel is needed and will measure the pressure in the tank, so it may turn off and on a few times during the fueling process. Depending on the station, the entire process can take as little as four to five minutes.

What You'll Learn
Hydrogen fuel cell vehicles (FCVs) are similar to electric vehicles (EVs)
FCVs and EVs also share similarities when it comes to refuelling. Filling up a hydrogen fuel cell vehicle is a relatively quick and easy process, similar to fuelling a gasoline-powered car. After inserting a credit card and selecting the fuel grade, the hydrogen nozzle is attached to the vehicle's fuel receptacle. The hydrogen then begins to flow automatically, with the infrared on the nozzle communicating with the car to determine how much fuel is needed. The entire process takes around five minutes, which is comparable to the time it takes to refuel a gasoline tank.
In terms of driving range, both FCVs and EVs offer the advantage of a long-distance travel capacity. FCVs can typically travel more than 300 miles on a full tank of hydrogen, while EVs are known for their impressive range capabilities, with some models offering over 200 miles on a single charge.
Despite these similarities, there are also notable differences between FCVs and EVs. One key distinction lies in their efficiency and environmental impact. FCVs have been criticised for the energy-intensive process of producing and storing hydrogen, which can result in higher carbon emissions compared to EVs. Additionally, the process of converting hydrogen into electricity within fuel cells has been associated with energy losses, impacting the overall efficiency of FCVs.

The hydrogen nozzle is attached to the vehicle's fuel receptacle
Filling up a hydrogen fuel cell car is a relatively simple process that is quite similar to filling up a gasoline-powered car. The process is also relatively dirt-free.
Once you have located a hydrogen refilling station, you will need to take off your dust cap, insert your credit card, and wait for approval. After approval, the machine will tell you that it is ready to fill. You will then pick up the nozzle, pull back on the blue collar so that it passes the yellow stripe, and insert it into the vehicle's fuel receptacle. Give the nozzle a little tug to make sure it is connected properly.
The entire process of filling up a hydrogen fuel cell car is quick, taking between 3 to 5 minutes for a full tank.

Hydrogen is dispensed as a pressurised gas
Filling up a hydrogen fuel cell car is a relatively simple process, but there are a limited number of places where you can pump hydrogen into a car. These can be found in California, New York, and Washington, D.C.
Once you've found a hydrogen pump, the process is similar to filling up a car with gas or diesel. First, take off your dust cap, then insert your credit card into the machine. After approval, wait for the machine to tell you it's ready to fill. Pick up the nozzle and pull back on the blue collar so that it passes the yellow stripe. Insert the nozzle into the vehicle's fuel receptacle, give it a little tug to make sure it's connected, and then push your grade. The infrared on the nozzle will communicate with the car, telling it how much fuel it needs, and the hydrogen will begin to flow automatically. The nozzle will turn off and on several times during the fueling process as it measures the pressure in the tank. It takes around five minutes to fill a hydrogen fuel tank—roughly the same amount of time as it takes to fill a gasoline tank.

The pressure is measured in the tank
Filling up a hydrogen fuel cell car is a relatively simple process. However, it is important to note that hydrogen refueling stations are not as common as traditional gas stations. Currently, retail hydrogen fueling stations are available in California, with funding in place for 100 more. Stations are also being developed in the Northeast, with eight states committing to putting 3.3 million zero-emission vehicles on the road by 2025.
When you arrive at a hydrogen refueling pump, you will likely see two options: 35 MPa and 70 MPa. MPa stands for megapascal, the unit of measurement for pressure. The 35 MPa option is typically used for heavy-duty and larger vehicles, such as buses, while lightweight vehicles use 70 MPa, which is the only option at newer refueling stations.
Once you have selected the appropriate option, the nozzle, which is about the size of a fire hose, is attached to the vehicle's fuel receptacle. The nozzle is then sealed using a twist-grip lever, and hydrogen begins to flow automatically. The nozzle communicates with the car, telling it how much fuel is needed, and the pressure in the tank is measured throughout the fueling process. This process takes around five minutes, similar to refueling a gasoline tank.
It is important to note that hydrogen is delivered at high pressure to provide an adequate driving range for hydrogen fuel cell vehicles. The higher the storage pressure, the greater the driving range and the lower the refueling frequency. Hydrogen fuel tanks are designed to store hydrogen safely at high pressures, and rigorous safety standards and testing procedures are in place to ensure the tanks' integrity.

Hydrogen fueling stations are available in California
Hydrogen fuel cell vehicles are not too dissimilar to electric vehicles (EVs) and gasoline-powered cars when it comes to refuelling. The process is relatively simple and quick, taking around five minutes or less to refuel a full tank of hydrogen.
In California, hydrogen fuelling stations are already in operation, with funding in place for more. The California Energy Commission is investing in an initial network of 100 public hydrogen stations across the state. The state's goal is to have 1.5 million zero-emission vehicles on California roads by 2025. The stations will be able to fuel up to 200 heavy-duty trucks or 2,000 cars per day.
The California Hydrogen Convention in Los Angeles highlighted the state's commitment to a robust hydrogen economy infrastructure. Air Products, the world's largest supplier of hydrogen, has committed to investing $15 billion by 2027 in clean energy megaprojects worldwide. This includes building a network of multi-modal hydrogen fuelling stations in California, as well as connecting Edmonton and Calgary in Canada.
The fuelling process at these stations is straightforward. After removing the dust cap, you insert your credit card into the machine, which looks like a regular fuel pump. Once approved, you wait for the machine to indicate that it is ready to fill. You then pick up the nozzle, pull back on the blue collar, insert and push your grade (H70 or H35, referring to the pressure at which hydrogen is dispensed). The nozzle communicates with the car, telling it how much fuel is needed, and the hydrogen begins to flow automatically.
