About the Fueling Station

The HyRide project has brought along with it Connecticut's first hydrogen fueling station, located in Hamden, CT. The station will exploit electrolysis technology; this process simply uses electricity to split water's bonds into hydrogen and oxygen. The sustainable and clean hydrogen can be used as fuel kept onboard the bus at ultra high-pressure.

GNHTD has teamed up with Connecticut's experienced company with special services in hydrogen energy, Avālence to create a secure and effective fueling station. The electrolysis method to be taken produces high-pressure hydrogen gas without a compressor. The notion of this method is that it increases energy efficiency, creates an affordable price, and ensures safety. An unusual and fascinating aspect of the electrolysis design is that it is easy and low cost to integrate renewable energy (such as solar, wind, etc.) into producing the electricity to split waters molecules. Also, the costs reduce drastically with this design of no compressor, resulting in less maintenance, inexpensive materials, and up to 50% less costs of hydrogen production use. Another feature that the design holds is the safety requirements.

Once the water molecules have been split into oxygen and hydrogen, the oxygen is tested for any traces of hydrogen before released back into the atmosphere, and the hydrogen is kept contained in high-pressure. The main computer on-sight of the station that controls the electrolysis process is located in an air sealed compartment. If hydrogen were to leak into the air, then this would automatically trigger the system to completely shut off. Efficiency, price, and protection were all topics kept in mind when building the fueling station.

The station is designed to generate10 kilograms of hydrogen per day and to dispense the fuel very quickly. The maximum storage capacity of the station is 48 kilograms of hydrogen. Keep in mind that, hydrogen fuel can last weeks depending the number of miles driven. In consequence, the amount of visits to the fueling station will reduce.

Project goal

To develop, test, and commercialize a hydrogen-fueled transit vehicle in Connecticut.
