Hydrogen Refueling Station (HRS) Solutions

When quoting a hydrogen station, several key requirements must be addressed. First, identify the source of hydrogen, specifying whether it will be supplied in gaseous or liquid form, as this impacts storage and dispensing infrastructure. Next, determine the types of vehicles that will be filled at the station, including their specifications and fueling requirements. Understanding how often these vehicles will need to fill up is crucial for assessing operational capacity. Additionally, analyze the demand profile to establish the expected volume of hydrogen needed over time, considering peak usage times and any anticipated growth in demand. ANGI Energy will work closely with you to develop a tailored solution that meets your current needs while providing the flexibility to scale with you in the future.

Hydrogen is not more or less safe than other fuels, it’s just different. Hydrogen vehicles and fueling stations must be designed around the unique properties of hydrogen with multiple safety features to prevent leaks and ensure safe usage. These include breakaway coupling, internal leak detection, emergency shut down button, connection to the site ESD system, tilt switch, CAT 4 PED relief valve

Hydrogen is dispensed as a pressurized gas, and the numbers (H70, H35) refer to the pressure at which hydrogen is dispensed. The H70 designation indicates a dispensing pressure of 70 Megapascals (MPa) (700 Bar) or approximately 10,000 psi. H35 indicates a dispensing pressure of 35 MPa (350 Bar) or approximately 5,000 psi.
Today’s hydrogen fuel cell electric passenger cars have H70 fueling systems, and can be fueled with either nozzle, H70 or H35, the difference being, H35 will result in a partial fill, due to the lower pressure.
Buses have fuel systems rated to 35MPa and only use an H35 nozzle. At the moment, medium- and heavy-duty trucks utilize both pressures, but many stakeholders expect that H70 – and perhaps H50 (50MPa or approximately 7,250 psi) – will be the likely pressures utilized in the near future.

The station is designed with modularity and scalability in mind. For example, all devices communicate over an ethernet connection to the local network, making it easy to set up communications with new equipment. Motor starter panels are also designed to be modular, requiring one per compressor. Finally, most major hydrogen station equipment includes a PLC or embedded system that includes the logic to run the device. Therefore, adding an additional equipment requires minimal changes to the existing infrastructure. This provides us with the ability to scale the site as demand increases.

The process is a familiar experience and not much different than filling up a car with gasoline. Our hydrogen dispensers are based on the North American Encore 700 and European SK700 with many of the same user interfaces and in terms of look and functionality. The dispensers include multimedia content to instruct user through the fueling process.

Hydrogen cars can be refueled in 3-5 minutes, buses can be refueled in 10 minutes, and trucks can be refueled in 10-15 minutes.
