HYDROGEN MEETING FUTURE NEEDS OF LOW CARBON MANUFACTURING VALUE CHAINS
Under the coordination of VERBUND, the steel manufacturer VOESTALPINE and SIEMENS, a PEM electrolyser manufacturer, propose the 26 month demonstration of a 6MW electrolysis power plant installed at the VOESTALPINE LINZ production site (Austria). After the pilot plant has been commissioned, the electrolyser will be prequalified with the support of APG, the Austrian transmission operator, in order to provide grid-balancing services such as primary, secondary or tertiary reserves while utilising the commercial pools of VERBUND. The demonstration is split into five pilot tests and quasi-commercial operation to show that the PEM electrolyser is able both to use timely power price opportunities (in order to provide affordable hydrogen for current uses of the steel making processes) and to attract additional revenues from grid services, which improves the hydrogen price attractiveness from a two-carrier utility such as VERBUND. Replicability of the experimental results on larger scales in EU28 for the steel industry (with input from TSOs in Italy, Spain and the Netherlands) is studied under the coordination of ECN. This involves a technical, economic and environmental assessment of the experimental results using the CertifHY tools. The roll-out of each result is provided by ECN in conjunction with policy and regulatory recommendations to accelerate deployment in the steel and fertilizer industry, with low CO2 hydrogen streams also being provided by electrolysing units using renewable electricity. The plausibility of this roadmap is reinforced at the start of the demonstration by creating an exploitation company involving the core industrial partners, which starts commercial operation of the Linz pilot plant immediately after the demonstration. Dissemination targeting the European stakeholders of the electricity, steel and fertilizer value chain actively supports the preparation of the practical implementation of the results in the 10 years after the end of the demonstration.
