Design, manufacturing, delivery, installation and commissioning of a cryogenic supply system to supply liquid hydrogen from a tank to up to four (4) test positions. • Pipeline Types: o Cryogenic Pipeline: Vacuum-insulated, DN40 PN16, approx. 110m in length o Cryogenic Transfer Pipeline (optional): Vacuum-insulated, DN25 PN16, approx. 120m in length o Cryogenic Exhaust Pipeline to Flare: Non-insulated, DN250 PN16, approx. 110m in length o Cryogenic Distribution Panel: Vacuum-insulated, primarily DN40 PN16, central distribution panel with purge functions and flow measurement o 3 (+1 optional) Panels at the Test Position: Vacuum-insulated, primarily DN40 PN16, compact panel with purge function and shut-off at the test site o Purge Lines for Helium and Nitrogen: Extending up to the panel boundary • Scope of Work (incl. but not limited to): o Detailed, execution, and installation planning (P&IDs are available) o Pipeline design & stress analysis, including support system design o Panel design o Procurement of all components o On-site installation o Coordination with other project lots • Services Provided by the Client: o Foundations o Control system and control pressure supply o Main pipe routes, including posts and pipe bridges for routing (excluding pipeline hangers)

The existing H2 Container Test Center has four test positions where at moment only tests with gaseous hydrogen can be performed. One of the test positions shall now be extend to liquid hydrogen and later liquid nitrogen (in the same system) infrastructure. For a better understanding of the whole system the technical specification includes the details of the gaseous supply system for the LH2 System (Lot 390) that was part of a previous call for tender. This tender is limited to the cryogenic supply system including the cryogenic panels, the field piping and the exhaust field piping (lot 392). Therefore, the following systems are needed: • Build up a cryogenic supply system for liquid hydrogen (also suitable for liquid nitrogen) with two new panels in the test center, including a new panel at the test position to connect the new infrastructures • Build up a cryogenic exhaust system for liquid hydrogen and process gases (gaseous hydrogen, nitrogen and helium) As interfaces DLR provides: • Gaseous Helium storage (gas bundles) • Cryogenic tank for liquid hydrogen and nitrogen • Flare stack for the exhaust system
