Development of a Mobile Hydrogen Refuelling Station

01 July 2021 - Published by Sonja Anna Charlotte Ruhnke

“The Pure Energy Centre is responsible for the delivery of a mobile hydrogen refuelling station to be used for training purpose. The station includes a completed and autonomous hydrogen production system, compression, storage and dispensing system for supply fuel to hydrogen vehicle. Currently the PEC has finalised the design of the refuelling station and already performed the manufacturing of the main equipment, which represents the core of the Hydrogen Dispensing System. The Electrolyser has been manufactured. The electrolyser is capable of producing hydrogen at 30 bars. It is currently being heavily tested. The Hydrogen Purifier allows to clean the hydrogen from water and any impurities that can be found in the hydrogen gas stream. Fuel cell cars do not tolerate impurities, and as such hydrogen has to be as clean as possible, to a nearly 100% clean. With the Purifier system, the hydrogen will be purified to a 99.999% level. Using humid hydrogen for hydrogen fuel cell vehicle can also be problematic, and that is why the purified extract most of the moisture and humidity coming from the electrolyser. As such, the Purifier play a critical role into the hydrogen filling station chain of operation. The Pure Energy Centre Hydrogen Purifier is ready and being tested in conjunction with the Electrolyser.  When the hydrogen is produced and then cleaned, it need to be compressed to higher pressures for later dispensing. In a common car filling station, this means that hydrogen needs to be pressurised to 900 bar and then stored. This is what the Pure Energy Centre 900 bar Compressor does. It takes the ultra-clean hydrogen from the output 30 Bar Purifier and pressurised to 900 bar. Again, the Pure-900 bar compressor has been manufactured and tests are being successfully undergoing. Currently, the different Pure Hydrogen Filling Equipment have been successfully manufactured and individually tested before the integration and final operation of the 700 bar refuelling station. Future activities involve the integration of the equipment and the construction of the mobile housing to accommodate all the equipment, the development of an overarching control and monitoring system and the final testing of the Hydrogen refuelling station as whole system. The learning of this activity will be integral part of the information dissemination activities and training that will be delivered from the project.”
