Custody transfer of HYDROGEN

摘要

Hydrogen is gaining traction as a versatile energy carrier that can help to decarbonise industries ranging from chemicals to heavy industry.However,the successful integration of hydrogen into the global energy infrastructure hinges on critical aspects,such as precise and reliable measurement technology.Custody transfer is a vital phase in the supply chain of any energy commodity,involving the precise measurement of the quantity and quality of the commodity being transferred.For traditional hydrocarbons,well-established technologies and standards exist to facilitate this process.However,the introduction of hydrogen and other low-carbon energy carriers necessitates new approaches.Hydrogen's unique properties,including its low density,high diffusivity and potential for material embrittlement,present significant challenges in production,transportation,and storage.Addressing these challenges requires advanced measurement technologies that can ensure the accuracy and reliability of hydrogen handling,particularly during custody transfer-the point at which ownership of the energy commodity changes hands.Accurate measurement during custody transfer is essential for several reasons.Firstly,it ensures that both the buyer and the seller are protected in the transaction,with the correct amount of hydrogen being accounted for.Secondly,accurate measurement is crucial for regulatory compliance,particularly in light of global standards and legislation that govern the hydrogen economy.The development of a global hydrogen economy requires the establishment of consistent and reliable measurement standards.Organisations such as the International Organization for Standardization(ISO)and the International Electrotechnical Commission(IEC)have developed standards specific to hydrogen,including ISO 21087 for the quality of hydrogen fuel and ISO 17089-1 for ultrasonic flow measurement systems.These standards provide the framework for accurate measurement and ensure consistency across different regions and industries.Compliance with these standards is not just a matter of technical accuracy; it is also a legal requirement in many jurisdictions.Failure to comply can result in significant penalties,including fines and restrictions on market access.
