A recent report by the National Physical Laboratory (NPL) sheds light on critical measurement challenges within the hydrogen sector, vital for advancing the UK's hydrogen economy and achieving net zero emissions targets. The report emphasizes the significance of addressing challenges across various aspects of the hydrogen value chain, including production, storage, distribution, and end-use technologies. Key objectives involve cost reduction in electrolytic hydrogen production, supporting infrastructure expansion, facilitating advanced material research, and enhancing regulatory frameworks. Notably, the UK government's commitment to investing £500 million in green hydrogen by 2030 underscores the nation's dedication to clean energy transition. Ali Al-Sikab, a Scientist at NPL, emphasizes the pivotal role of metrology in standardizing hydrogen technologies, fostering commercial adoption, and driving broader industry acceptance. NPL expresses its readiness to collaborate with governmental bodies, industry partners, and academic institutions to tackle the identified challenges effectively. By leveraging concerted efforts, the aim is to propel hydrogen technologies as a competitive and eco-friendly alternative energy source, pivotal for the UK's sustainable energy transition. The report serves as a call to action for collective engagement in overcoming barriers and accelerating the integration of hydrogen solutions into diverse industrial sectors.
