The surge in demand for hydrogen as a clean energy source is accompanied by various challenges that need to be addressed for its widespread adoption. Servomex, a global leader in gas analysis, has released a white paper that examines these challenges in detail. The paper emphasizes the importance of purity, safety, cost-effective production, and environmental compliance in the utilization of hydrogen. It showcases how advanced sensor and analyser technology is playing a pivotal role in overcoming these challenges and making hydrogen a viable solution for industrial decarbonisation. Additionally, the white paper explores the significance of technologies such as ASUs and advanced gas monitoring in the transition from grey to green hydrogen, which is crucial for supporting sustainable innovations like zero-carbon steel and next-generation electrolysers. For businesses already involved with hydrogen or considering its integration into their operations, this paper serves as an essential guide for achieving success and ensuring sustainability in the evolving landscape of clean energy.
