The article highlights the indispensable role of hydrogen in achieving a carbon-neutral future and emphasizes its advantages in storing and transporting energy efficiently, thereby enhancing flexibility in energy supply. The author, Dr. Martin Thedens, Chair of IEC TC 31, underscores the importance of hydrogen and its derivatives in the transition to an 'all electric society.' The standards issued by IEC TC 31 and its SCs are instrumental in ensuring the safe use of hydrogen, covering aspects such as classification of flammable substances, hazardous areas, and ex equipment. The article also mentions the recent IECEx International Hydrogen Conference 2024 held in Singapore, where key players in hydrogen technology converged to discuss existing technical solutions and future requirements. Dr. Thedens outlines future tasks for IEC TC 31, including the development of explosion characteristics for various conditions, extension of requirements for special applications like flame arrestors for hydrogen, and addressing the use of LOHC and oxide electrolyser cells. The formation of AG 59 'Hydrogen Advisory Group' by IEC TC 31 reflects the growing importance of hydrogen technology and aims to provide guidance for its use while avoiding duplicated work and conflicting requirements. The overall sentiment of the article is positive, highlighting the essential nature of hydrogen in shaping a sustainable future.
