In an insightful interview with Rene Leven, Segment Leader Hydrogen and CCUS at John Crane, the discussion delves into the company's crucial role in supporting hydrogen infrastructure. John Crane offers a diverse product portfolio tailored to support modular hydrogen solutions like mobile refuelling stations. Their particle and coalescing filters are engineered to meet international purity standards, ensuring the integrity of critical rotating equipment without hydrogen leakage. The company also addresses material compatibility concerns, particularly hydrogen embrittlement, through research and development efforts to create embrittlement-resistant materials. Furthermore, John Crane's monitoring tools play a key role in identifying energy inefficiencies and ensuring the reliable operation of essential components like boil-off gas compressors in LNG storage facilities. By providing condition monitoring solutions for rotating machinery, John Crane helps detect deviations from normal operating parameters, enabling preventive maintenance and increasing the meantime between failures. Moreover, the interview highlights the critical key performance indicators (KPIs) for evaluating sealing systems in hydrogen applications. These KPIs revolve around reliability and purity, with factors like uptime, service level agreements, mean time between failures, and mean time to resolution being essential metrics. John Crane's commitment to developing technologies that enhance reliability and address material challenges underscores its positive impact on hydrogen-powered energy generation systems.
