WELCOME TO HERMES:

Hydrogen Efficient Purification Using Membranes In Industrial Gas Streams Analiz

The “HERMES” project advances hydrogen separation and purification technologies through the development, scaling-up, and industrial demonstration of innovative membrane systems, while conducting comprehensive evaluations for safety, environmental impact, social acceptance, and cost reduction in industrial settings.

The project aims at developing and scaling up two membrane technologies (Pd-based and Carbon-based membranes), to design and build 2 prototypes, and to prove the technologies at two industrial sites (in Italy and in Türkiye), for separation of pure hydrogen for 5 different streams of industrial interest.

Officially launched on January 1, 2025, and coordinated by H2SITE, HERMES will provide a quantum leap in the development of efficient hydrogen separation and purification technology to reduce the cost of hydrogen purification by utilization of two groundbreaking membrane technologies: Hydrogen-selective palladium membranes and Carbon Molecular Sieve membranes (CMS).

Through its newsletters, HERMES will provide regular updates on progress, events, and key milestones as these solutions are implemented and tested in various real-world scenarios.

Innovation Through Collaboration: Meet the HERMES Consortium

HERMES consortium, composed of 7 partners from 4 different countries, is advancing hydrogen separation and purification technologies through cutting-edge membrane innovations.

TU/e Hosts 2nd HERMES General Assembly Meeting

The HERMES Project Consortium convened its second General Assembly meeting on July 10, 2025, at Eindhoven University of Technology (TU/e), bringing together partners from across Europe to discuss progress and future directions of the Horizon Europe-funded project focused on advanced hydrogen membrane technologies.

Pilots & Use-Cases: Real-World Applications of HERMES’ Solutions

The HERMES project will play a pivotal role in demonstrating the effectiveness and feasibility of CMS and Pd membrane-based hydrogen separation technologies at industrial scale. By evaluating membrane performance under real-industrial conditions and assessing key parameters, the project will provide valuable insights to industry stakeholders, paving the way for widespread adoption of advanced hydrogen separation solutions.
Transforming Industry: HERMES’ Role in Environmental Impact & Safety in Industrial Settings The HERMES project is pioneering a sustainable shift in industrial hydrogen purification by integrating advanced membrane technologies with a comprehensive approach to environmental and safety considerations. A core objective of HERMES is to significantly reduce the energy consumption and cost of hydrogen purification—targeting below 3.5 kWh/kg and under 1 €/kg—through the development and deployment of two innovative membrane systems: Hydrogen-selective palladium membranes and Carbon Molecular Sieve membranes.

Beyond technical innovation, HERMES places strong emphasis on the holistic evaluation of its technologies in real industrial conditions. The project conducts thorough Life Cycle Assessments (LCA), Life Cycle Costing (LCC), and Techno-Economic Analysis (TEA) to assess the environmental footprint and cost-effectiveness of the proposed solutions. Furthermore, safety is central to the project’s mission, with detailed Preliminary Hazard Analysis (PHA) undertaken for each demonstration case. By addressing environmental, economic, and safety aspects in tandem, HERMES not only advances membrane technology but also contributes to the broader goal of decarbonizing industrial sectors. This integrated approach ensures that the solutions developed are not only innovative but also scalable, safe, and sustainable.

Shaping the Future: How HERMES is Shaping Hydrogen-selective palladium membranes

HERMES is setting a new benchmark in hydrogen purification by advancing membrane-based technologies that are efficient, scalable, and tailored for real-world industrial needs. At the heart of the project are two cutting-edge membrane systems—Palladium-based and Carbon Molecular Sieve (CMS) membranes—designed to separate high-purity hydrogen from complex gas streams across diverse industrial processes.

Through an integrated innovation approach, HERMES develops, scales up, and demonstrates these technologies in two operational prototypes at TRL7. These systems are capable of processing up to 100 kg of hydrogen per day, proving their readiness for large-scale deployment. The flexibility and robustness of the membranes allow them to operate under varying hydrogen concentrations and industrial conditions, making them suitable for multiple sectors including refining, petrochemicals, and gas transportation.

By leveraging the combined expertise of leading research institutions, technology developers, and industrial partners, HERMES is shaping a new generation of hydrogen purification technologies. These advances are crucial for enabling cleaner hydrogen production and accelerating Europe’s transition to a low-carbon, circular industrial future.

The HERMES project provides several engagement opportunities for stakeholders and industry professionals:

This project is supported by the Clean Hydrogen Partnership and its members under the grant agreement No 101192352. This Partnership receives support from the European Union’s Horizon Europe research and innovation programme, Hydrogen Europe and Hydrogen Europe research.
