The BeBoP project, supported by the EU and its Clean Hydrogen Partnership, aims to revolutionize hydrogen-powered fuel cells for heavy-duty mobility sectors. The project targets improving Balance of Plant (BoP) components such as air compressors, humidifiers, and DC/DC converters to enhance the efficiency and reliability of fuel cell systems. By bringing together key component developers, a powertrain designer, and research institutions, the BeBoP project aims to develop more efficient, compact, and reliable components that can monitor fuel cell health. The innovations in BoP components will advance fuel cell systems for heavy-duty applications like road, maritime, railway, and aviation. The project will deliver an efficient air compressor, a compact DC/DC converter with monitoring capabilities, and an improved humidifier technology. Modeling expertise from DLR and SINTEF will be employed to develop and optimize the fuel cell system, ensuring efficient operation. The project will test these components to achieve steady-state efficiency and assess their performance in heavy-duty cycles for long-distance vehicles. By scaling up the components with European manufacturers, the BeBoP project aims to facilitate the large-scale deployment of fuel cell systems. Ultimately, the project strives to bring reliable technology to the market, potentially standardizing component design to ease industrialization. The BeBoP project is coordinated by SINTEF AS (Norway) and includes consortium partners from Germany, France, Italy, and Switzerland, focusing on beyond state-of-the-art efficiency and innovation in fuel cell components. The total budget for the 42-month project is 3,983,049 Euro, with funding from the EU and the Swiss State Secretariat for Education, Research, and Innovation.
