Pilot Electrolysis Plant in Herne: Hydrogen Technology for Industrial Applications
Advancing Hydrogen Technology
Known internally as the H₂annibal project, Evonik's collaboration with Siemens Energy focuses on the use of electrolysis technology to produce hydrogen from renewable electricity for applications at the Herne site.
Named after the former Hannibal coal mine, the pilot electrolyzer project was launched in late 2022 and receives funding from the German Federal Ministry of Education and Research. The project investigates the use of hydrogen as a feedstock for the production of VESTAMIN® IPD, a material used in applications including wind turbine rotor blades. The project is scheduled to conclude in mid-2025 and supports the evaluation of hydrogen technologies under industrial operating conditions.
Hydrogen Production at the Herne Site
The PEM (proton exchange membrane) electrolyzer has a capacity of 8 MW and is expected to supply up to 45% of the site's hydrogen demand as well as 100% of its oxygen demand for production processes. The project contributes to the integration of electrolysis technology into industrial manufacturing operations.
Estimated Emissions Reduction
Based on project estimates, operation of the electrolyzer could avoid approximately 12,000 metric tons of CO₂ emissions annually compared with conventional hydrogen production methods. The project also supports broader efforts to evaluate hydrogen-based technologies for industrial applications.
Technology Development and Site Transformation
The H₂annibal project forms part of Evonik's broader investment program for production processes and infrastructure. Alongside other initiatives at the Herne site, the project supports efforts to improve resource efficiency, reduce emissions, and evaluate alternative energy and feedstock sources.
Through collaboration with industry and research partners, Evonik continues to explore technologies that can contribute to the future development of chemical manufacturing.
