Hydrogen Fueling

As the purchase of fuel cell vehicles becomes increasingly more prevalent among consumers, the fueling infrastructure is growing at a rapid pace. This has elevated the demand for hydrogen fuel. Converting energy from renewable sources into hydrogen via PEM water electrolysis, on-site gas generators produce green hydrogen to drive carbon-free emission objectives.

Brentwood, DC

Advancements in hydrogen fueling station design are now showcased in our nation’s capital. Supported by the Department of Energy and the National Renewable Energy Laboratory, the station is being hosted by the National Park Service at their Brentwood Avenue maintenance facility for a duration of four years. Featuring a novel and compact equipment arrangement, the station allows for easy siting and accelerated commissioning. As a collaborative project, Proton OnSite provided the electrolyzer and accessories to enable a fully operational fueling station that will serve fuel cell electric vehicle (FCEV) deployment in the metro Washington area, and provide an educational and outreach opportunity to zero emission vehicle stakeholders.  The station is available to fuel FCEVs involved in activities associated with the demonstration, while also validating the safety and reliability of PEM electrolysis as a source of zero emission fuel. Though not a public access station, the advancements in sustainable transportation and fueling demonstrated through this project will enable public retail stations of the future.

Wallingford, CT

Eliminating costs associated with gas delivery, on-site gas generation equipment is available to produce hydrogen as a fuel source for vehicles on demand. Connecticut's only public hydrogen fueling station is located in Wallingford, CT. Proton OnSite's PEM electrolyzer generates a steady source of hydrogen fuel for fuel cell vehicles at their point of use. This hydrogen is the ultimate zero-emission fuel when PEM systems are paired with renewable sources of electricity. 

Fun fact: Hydrogen fueling projects really hit home for us, this commercial fueling station is located at Proton OnSite's headquarters!

Emeryville, CA

In Emeryville, CA, a state-of-the-art fueling facility dispenses hydrogen produced from natural gas and from renewable electricity. The source of the renewable energy generated at the location is water and solar power. Funded by a grant from the California Air Resources Board, the station dispenses hydrogen for FCEV buses and cars. Aware that this station would be accessible to the public, Proton OnSite gladly supplied the electrolyzer to support this project. This equipment allows the station to generate and dispense hydrogen at a capacity of 600kg per day.

Freiburg, Germany

Fraunhofer ISE operates a hydrogen fueling station that generates hydrogen on location from solar electricity. Captured by the station’s own PV system, the use of this sustainable resource demonstrates the benefits of leveraging renewables to produce hydrogen. Refueling at a 700 bar storage pressure, vehicles at the location take three to five minutes to fill. In addition, the station features two fuel cell vehicles used for research and to serve as company cars. The  fueling station is based on a modular design. Proton OnSite provided the electrolyzer to produce the hydrogen at 30 bar. Ancillary equipment is then employed to compress the gas to pressures appropriate for refueling.

Hamburg, Germany

Fuel cell electric vehicles (FCEVs) are essential to achieving a low-carbon transport system. When operated, compressed hydrogen is converted into electricity that powers the motor. The benefit is that this produces no emissions from the tailpipe, only water. When renewable electricity is employed to produce the hydrogen, the vehicle is effectively driven without generating any carbon emissions. Germany is working toward reaching a nationwide network of 400 hydrogen refueling stations by 2023. The Shell station, in Hamburg, is a contribution to attaining that objective. Proton OnSite provided the electrolysis technology necessary to establish the station in this location.

Frequently Asked Questions

Why on-site gas generation?

On-site gas generation is a reliable solution to produce the hydrogen, nitrogen or zero air you need on demand. Unlike cylinders, gas generators offer customers convenience, safety, and peace of mind, a result of their ability to generate gas on demand at a consistent purity. Using an on-site gas generator not only saves valuable facility space, but also optimizes the operation. No more waiting for delivery, moving high pressure cylinders, or risking contamination during cylinder change-outs. On-site gas generators provide security of supply in a simple plug-and-play package. 

Are on-site gas generators sustainable/green?

At Proton Onsite,  Yes.  In comparison to other hydrogen-generating electrolysis technology, there is no KOH required to operate Proton's generators. Also, there is no CO2 byproducts in the production of our hydrogen.  Our process consists of splitting hydrogen and oxygen via PEM electrolysis.  

What is PEM Electrolysis?

PEM (proton exchange membrane) water electrolysis simply splits pure deionized water (H2O) into its constituent parts, hydrogen (H2) and oxygen (O2), via an electrochemical reaction. When a DC voltage is applied to the electrolyzer, water fed to the anode (or oxygen electrode) is oxidized to oxygen and protons, while electrons are released. The protons (H+ ions) pass through the PEM to the cathode (or hydrogen electrode), where they meet electrons from the other side of the circuit, and are reduced to hydrogen gas.
