Data generation of large-scale green hydrogen production at the Hydrogen Lab Bremerhaven

Presented by: Anna Heuschmann
Fraunhofer IWES
General scope
Green hydrogen as renewable fuel of non-biological origin (RFNBO) is defined in the EU Renewable Energy Directive (REDIII). These requirements must now be met to produce the targeted green hydrogen which provides operators of hydrogen plants an economic perspective. To minimize risks and accelerate the hydrogen market utilizing models, which are validated with reliable data from large scale testing of electrolysers in dynamic conditions, is unavoidable. The Hydrogen Lab Bremerhaven (HLB) collects data from dynamic operation of electrolysers and does research along the entire green hydrogen supply chain.
Main results
Data from operation of the two different electrolysers was collected for various operation scenarios as well as occurring faults and stand still times. The electrolysers were operating in different load ranges including start-up and shut-down procedures. Data and experience for storage fillings in the low- and high-pressure area were gained with varying use of the three compressors based on their availability. In addition, the first trailers for hydrogen transport have been filled. Data about the wind forecast and the created prediction of power consumption for the HLB is available just like the actual produced and consumed power of the test field as part of meeting the RFNBO requirements.
Methods
The HLB, built and operated by the Fraunhofer IWES, offers a hydrogen infrastructure that provides a wide range of operating and testing possibilities with two electrolysers (1 MW PEM, 1.3 MW alkaline), a fuel cell, a CHP-plant and associated peripherals such as storage units, trailer filling station and compressors. It can be flexibly expanded with multiple free test pads. One of these test pads is already equipped to function as a desalination test stand for research regarding offshore electrolysis as part of the H2Mare project.
Power can be supplied from the public grid or from existing electrical testing infrastructure like a converter test rig and a 44 MVA grid emulator. These test rigs were designed for wind energy applications and are integrated into the HLB to enable a wide array of real-world test scenarios and various stand-alone grid operating modes. A Power Purchase Agreement ensures the production of green hydrogen in accordance with the currently valid legal framework. The HLB started its test operation last year and since July it´s fully handed over to Fraunhofer IWES.
Relevance
The set hydrogen targets need an accelerated ramp-up of the green hydrogen industry. With the REDIII closing in to practical applicability and economic relevance a dynamic operation of electrolysers is inevitably necessary. The lack of data of large-scale testing and validated models in this area leads to high risks in project planning and realization which causes many cancellations of hydrogen projects due to uncertain future perspectives.
Major conclusions drawn
The operation of the HLB collects a lot of important data along the green hydrogen supply chain, from the interaction of hydrogen components to individual system data in dynamic operation. Different operation scenarios and dynamic changes of the units are recorded, and the storage periphery is successfully tested. The collected data also gives first insights towards real-world availability times and open issues that still prevent permanent reliable operation.
Results from the operation of Hydrogen Hybrid Power Systems in large-scale are an inevitable step towards the expansion of the technology.
