Regulations, Codes & Standards (RCS)

Although hydrogen has been used in industry for decades its use as a fuel for vehicles or stationary power generation in consumer environments is relatively new. As such hydrogen and fuel cell codes and standards are in various stages of development. Industry manufacturers the government and other safety experts are working with codes and standards development organizations to prepare review and promulgate technically-sound codes and standar Read More

Australia’s gas infrastructure is currently subject to regulations that were designed for a natural-gas only network system. Future Fuels CRC has released a full report and database of regulations to share exactly how Australia’s current gas regulations can be modernised to enable hydrogen biomethane and other potential future fuels.This research thoroughly assessed Australia’s current regulatory framework to identify the regulations that will require mode Read More

Purpose: The Standards module of the FCHO presents a large number of standards relevant for the deployment of hydrogen and fuel cells. The standards are categorized in order to enhance ease of access and usability. The development of sector-relevant standards facilitates and enhances economies of scale interoperability comparability safety and many other issues. Scope: The database presents European and International standards. Standards from Read More

The European Strategy Forum on Research Infrastructures (ESFRI) recognizes in its roadmap for Research Infrastructures that ?in the near future hydrogen as an energy carrier derived from various other fuels and fuel cells as energy transformers are expected to come into a major role for mobility but also for different other mobile and stationary applications? |1|. This modern hydrogen driven society lags far behind the reality. Because of that it is confor Read More

There is no inherent property of hydrogen that makes it unsuitable for metering at distribution or transmission pressures. Towns gas containing large percentages of hydrogen was used for many years in the UK and continues to be in use in Hong Kong and Singapore. Many manufacturers sell their ordinary mechanical gas meters as suitable for hydrogen in a laboratory or industrial situation; unfortunately lack of demand has meant that none of these Read More

The development and promulgation of codes and standards are essential to establish a market-receptive environment for commercial hydrogen-based products and systems. The focus of the U.S. Department of Energy (DOE) is to conduct the research and development (R&D) needed to strengthen the scientific basis for technical requirements incorporated in national and international standards codes and regulations. In the U.S. the DOE and its i Read More

Two key aspects of hydrogen safety are (1) incorporating data and analysis from research development and demonstration (RD&D) into the codes and standards development process; and (2) adopting and enforcing these codes and standards by state and local permitting officials. This paper describes work that the U.S. Department of Energy (DOE) is sponsoring to address these aspects of hydrogen safety. For the first DOE is working with the automo Read More

The report makes a recommendation for a minimum hydrogen purity standard to be used by manufacturers developing prototype hydrogen appliances and during their subsequent demonstration as part of the Hy4Heat programme. It makes a recommendation for a hydrogen purity level with the aim that it is reasonable and practicable and considers implications related to hydrogen production the gas network and cost.This report and any attachment is Read More

Hydrogen is expected to play a critical role in the move to a net-zero economy. However large-scale deployment is still in its infancy and there is still much to be done before we can blend hydrogen in large volumes into gas networks and ramp up the production that is required to meet demands of the energy transport and industry sectors. KTN Global Alliance will host two webinars to explore these challenges and opportunities in hydrogen blending on t Read More

Hydrogen fuelled vehicles can play a key role in the decarbonisation of transport and reducing emissions. To ensure the durability of fuel cells a specification has been developed (ISO 14687) setting upper limits to the amount fraction of a series of impurities. Demonstrating conformity with this standard requires demonstrating by measurement that the actual levels of the impurities are below the thresholds. Currently the industry is unable to do so for mea Read More

This standard has been created for the specific purposes of the Hy4Heat programme. The standard was commissioned in 2018 and this version was considered and approved by the relevant IGEM committees in May of 2020. This version of the standard was developed using the latest publicly available information at that time and may include some conservative requirements which further research may deem not necessary. The supplement will Read More

IGEM/TD/13 Standard applies to the safe design construction inspection testing operation and maintenance of pressure regulating installations (PRIs) in accordance with current knowledge and operational experience.This Supplement provides additional requirements for new PRIs to be used for the transmission of Hydrogen including Natural Gas/Hydrogen blended mixtures (subsequently referred to as NG/H blends) and for the repurposing of Read More

IGEM/TD/13 Standard applies to the safe design construction inspection testing operation and maintenance of pressure regulating installations (PRIs) in accordance with current knowledge and operational experience.This Supplement provides additional requirements for new PRIs to be used for the transmission of Hydrogen including Natural Gas/Hydrogen blended mixtures (subsequently referred to as NG/H blends) and for the repurposing of Read More

In this paper we review our recent results in developing gas sensors for hydrogen using various device structures including ZnO nanowires and GaN High Electron Mobility Transistors (HEMTs). ZnO nanowires are particularly interesting because they have a large surface area to volume ratio which will improve sensitivity and because they operate at low current levels will have low power requirements in a sensor module. GaN-based devices offer the adva Read More

In response to the UK Government’s commitment to achieve net-zero carbon emissions by 2050 a range of research and demonstration projects are underway to investigate the feasibility of using hydrogen in place of natural gas within the national transmission and distribution system. In order for these projects to achieve their full scope of work a mechanism for performing hazardous area classification for hydrogen installations is required. At pre Read More

The literature lacks a systematic analysis of HRS equipment and operating standards. Researchers policymakers and HRS operators could find this information relevant for planning the network's future expansion. This study is intended to address this information need by providing a comprehensive strategic overview of the regulations currently in place for the construction and maintenance of hydrogen fueling stations. A quick introduction to Read More

The supplement to the standard IGEM/TD/1 gives the additional requirements and qualifications for pipelines transporting hydrogen and hydrogen/natural gas blends (NG/H blends) at pressures at MOP exceeding 7 barg.Where there is no numbered section in the supplement corresponding to a section in the main document the requirements of the main document apply in full. Where there is a corresponding numbered section in the main document the num Read More

In this article we draw on findings from a mixed-methods international survey of experts in the energy sector (n = 179) to better understand the role of legitimacy theory in informing the development of renewable hydrogen standards certification and labelling (SCL). The investigation is viewed through two conceptions of legitimacy: the sociological legitimacy of increasing the availability of renewable hydrogen technologies and the normative legitima Read More
