en.Wedoany.com Reported - On June 10, 2026, Innexis and E2S Power demonstrated a graphite thermal storage unit based on TWEST (Traveling Wave Energy Storage Technology) at the Pharma & Life Science Park Marburg, with a capacity of 6 MWh, aiming to combine supply security, sustainability, and technological innovation.
For the pharmaceutical industry, energy supply is a prerequisite for stable processes, quality, regulatory safety, and continuous supply to patients worldwide. Marburg Mayor Thomas Spies stated that the Life Science and Pharma Park, with its future-oriented energy infrastructure, offers companies a high degree of supply security and predictable energy costs, making them more independent of volatile energy markets, which has become a clear competitive advantage.
Innexis Group CEO Martin Egger noted that combining supply security, regulatory requirements, and decarbonization requires reliable infrastructure and the courage to implement new solutions. He pointed out that the R&D, manufacturing, and service ecosystem formed within the park provides ideal conditions for pharmaceutical, biotechnology, and life science companies, and the project is also supported by the Fraunhofer Institute for Energy Infrastructures and Geothermal Energy (Fraunhofer-Institut für Energieinfrastruktur und Geothermie).
The graphite thermal storage unit stores surplus electricity from renewable sources as thermal energy and releases it as superheated steam when needed, with an efficiency of up to 95%. E2S Power CEO Sasha Savic emphasized that the TWEST system demonstrates how renewable energy can be used for industrial thermal processes, marking an important step for energy-intensive industries like pharmaceuticals in advancing sustainability and supply security. The pilot unit can meet up to 10% of the steam demand at the Görzhausen section of the Marburg site.
The pilot unit is planned to test various operating conditions at different times and under different market conditions over a nearly two-year testing phase. If the test runs are successful, the storage capacity can be expanded from the current 6 MWh to 60 MWh, and with full expansion, it can achieve an electrical connection power of 10 MW and a steam output of up to 13 t/h. A decision on implementation is expected by 2028.
The INNEXIS Group has set a goal of achieving carbon neutrality by 2030 at the Marburg Life Science and Pharma Park. Currently, the park fully meets its electricity needs from renewable sources. A large ground-mounted photovoltaic plant was commissioned last year, and together with photovoltaic modules on the roof of a new parking garage, the total installed capacity reaches approximately four megawatts. Additionally, there are two underground ice storage systems with volumes of 870 cubic meters and 1,500 cubic meters, respectively, used for cooling the logistics center and research building. By 2030, six wind turbines, each with a capacity of 7 MW, are planned to be built on the "Marburger Rücken" (Marburg Ridge).
