ZAL (Hamburg): Hydrogen Liquefier System for Small-Scale Delivery Rates as part of the LH2 Transport System at the Hanseatic Hydrogen Center for Aviation and Maritime (H2AM)

Description du marché

The required device is a hydrogen liquefier, that ensures production of aprox. 10 kg per day liquid hydrogen with very few external supplies. That means hydrogen and electricity are provided for operation including the option of later use of liquid nitrogen for H2 precooling. The liquefier itself needs to be safe regarding explosive dangers. All legal and regulatory requirements for an operation in Europe, Germany and Hamburg must be applied. It is intended to operate the Liquefier System normally highly automated and 24/7 with no or minimum operator interaction. As the LH2 demand will vary, the Liquefier System should be switched off and restarted regularly by the user without additional external support. Besides the automated operation it may be advantageous to run the Liquefier System manually for troubleshooting or special operations. Maintenance will be done in "Off" or "Manual" mode. The LH2 shall be transferred to mobile dewars of different sizes (not part of this tender).The Liquefier System shall reuse boil-off gases not only from internal process but also from external fueling processes, if technically feasible. An automated operation requires a Programmable Logic Controller (PLC). This should be industrial standard of any expert supplier who uses well distributed software for programming. For the operation of the Liquefier System, the required infrastructure including H2 provision or chimney are not part of this tender. The Liquefier System shall be designed state of the art including ortho-para transformation to achieve high LH2 storage times. Further information can be found in the procurement documents.
