This Supplement gives additional requirements and qualifications for the transmission of Hydrogen including Natural Gas/Hydrogen blended mixtures (subsequently referred to as NG/H blends) and for the repurposing of Natural Gas (NG) pipelines to Hydrogen service. For the purposes of this document any NG/H blend above 10% MOL is considered to be an equivalence to 100% hydrogen. For blends below 10% MOL there is no evidence to confirm tha 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

This study has developed traceable standards for evaluating impurities in hydrogen fuel according to ISO 14687. Impurities in raw H2 including sub mmol/mol levels of CO CO2 and CH4 were analyzed using multiple detectors while avoiding contamination. The gravimetric standards prepared included mixtures of the following nominal concentrations: 1 2 3e5 8e11 17e23 and 47e65 mmol/mol for CO2 CH4 and CO O2 N2 Ar and He respectively. The expanded un Read More

As a party to the United Nation Framework Convention on Climate Change (UNFCCC) Malaysia is committed to reduce its greenhouse gases (GHG) emission intensity of gross domestic product (GDP) by 45% by 2030 relative to the emission intensity of GDP in 2005. One of the ways for Malaysia to reduce its GHG emission is to diversify its energy mix and to include hydrogen fuel cell (HFC) in its energy mix. Since Malaysia does not have any legal framework Read More

A range of existing and newly developed hydrogen standards certification and labelling (SCL) schemes aim to promote the role of ‘renewable’ ‘clean’ or ‘green’ hydrogen in decarbonising energy transitions. This paper analyses a sample of these SCLs to assess their role in the scaling up of renewable hydrogen and its derivatives. To analyse these hydrogen SCLs we embellish a novel conceptual framework that brings together Sustainability Systems Thinki Read More

Fuel cell vehicles are considered as the direct alternative to fuel vehicles due to their similar driving range and refueling time. The United Nations World Forum for Harmonization of Vehicle Regulations (UN/WP29) released the Global Technical Regulation on Hydrogen and Fuel Cell Vehicles (GTR13) in July 2013 which was the first international regulation in the field of fuel cell vehicles. There exist some differences between GTR13 and the existing safety te Read More

Hydrogen is widely recognized as a promising clean energy carrier but its highly flammable and explosive nature presents significant safety challenges in its production storage transportation and usage. Addressing these challenges is critical for the successful integration of hydrogen into global energy systems aligning with the United Nations’ sustainable development goals to support the transition to a low-carbon future. This study aims to provide a com Read More

Hydrogen specifications for different scenarios are various. Based on national standards for China a comparison of hydrogen specification standards is discussed in this paper including specification standards for industrial hydrogen pure hydrogen high pure hydrogen ultrapure hydrogen hydrogen for electronic industry and hydrogen for PEM FCVs. Hydrogen purity for electronic industry is greater than that for industrial hydrogen pure hydrogen Read More
