Closing the Regulatory Gaps and Advancing Hydrogen Infrastructure Deployment in Australia
Sep 2019
Publication
With downward trends in Australian equipment manufacturing there are increased numbers of overseas designed manufactured and certified hydrogen systems being introduced into Australia. In parallel there are also opportunities for hydrogen and its carriers to be exported to overseas. Certainty of reputable codes and standards is important to meet regulatory requirements and community safety expectations locally and overseas.This paper Read More
Synthesis of Spherical V-Nb-Mo-Ta-W High-Entropy Alloy Powder Using Hydrogen Embrittlement and Spheroidization by Thermal Plasma
Dec 2019
Publication
V-Nb-Mo-Ta-W high-entropy alloy (HEA) one of the refractory HEAs is considered as a next-generation structural material for ultra-high temperature uses. Refractory HEAs have low castability and machinability due to their high melting temperature and low thermal conductivity. Thus powder metallurgy becomes a promising method for fabricating components with refractory HEAs. Therefore in this study we fabricated spherical V-Nb-Mo-Ta-W HEA powder u Read More
Dispersion of Cryogenic Hydrogen Through High-aspect Ratio Nozzles
Sep 2019
Publication
Liquid hydrogen is increasingly being used as a delivery and storage medium for stations that provide compressed gaseous hydrogen for fuel cell electric vehicles. In efforts to provide scientific justification for separation distances for liquid hydrogen infrastructure in fire codes the dispersion characteristics of cryogenic hydrogen jets (50–64 K) from high aspect ratio nozzles have been measured at 3 and 5 barabs stagnation pressures. These nozzles are Read More
Long-Term Hydrogen Storage—A Case Study Exploring Pathways and Investments
Jan 2022
Publication
Future low-carbon systems with very high shares of variable renewable generation require complex models to optimise investments and operations which must capture high degrees of sector coupling contain high levels of operational and temporal detail and when considering seasonal storage be able to optimise both investments and operations over long durations. Standard energy system models often do not adequately address all these issues w Read More
Liverpool-Manchester Hydrogen Cluster: A Low Cost, Deliverable Project
Aug 2017
Publication
Emissions from natural gas combustion and use are the largest source of greenhouse gas (GHG) emissions in the UK. The use of hydrogen in place of natural gas in principle offers a potential route to long term widespread decarbonisation of gas distribution networks as shown by the Leeds City Gate (‘H21’) study.1 The purpose of considering conversion to hydrogen is to deliver widespread carbon abatement across the UK at lower cost than alternative decar Read More
Transitioning to Hydrogen - Assessing the Engineering Risks and Uncertainties
Jun 2016
Publication
Transitioning to Hydrogen a joint report from five engineering organisations focuses on the engineering challenges of replacing natural gas in the gas distribution network with hydrogen in order to reduce emissions. The production of this report is timely following the commitment from Government this week to legislate for net zero emissions by 2050. It is expected that hydrogen will play a big part in the reduction of emissions from the heating tra Read More
Safety Considerations of Hydrogen Application in Shipping in Comparison to LNG
Apr 2022
Publication
Shipping accounts for about 3% of global CO2 emissions. In order to achieve the target set by the Paris Agreement IMO introduced their GHG strategy. This strategy envisages 50% emission reduction from international shipping by 2050 compared with 2008. This target cannot be fulfilled if conventional fuels are used. Amongst others hydrogen is considered to be one of the strong candidates as a zero-emissions fuel. Yet concerns around the safety of its st Read More
Single-catalyst High-weight% Hydrogen Storage in an N-heterocycle Synthesized from Lignin Hydrogenolysis Products and Ammonia

Publication
Large-scale energy storage and the utilization of biomass as a sustainable carbon source are global challenges of this century. The reversible storage of hydrogen covalently bound in chemical compounds is a particularly promising energy storage technology. For this compounds that can be sustainably synthesized and that permit high-weight% hydrogen storage would be highly desirable. Herein we report that catalytically modified lignin an indige Read More

Welsh Government’s Department for Economy, Skills & Natural Resources Briefing: Cardiff University’s Expertise to Help Address the Challenges to Creating a CO2 Circular Economy for Wales
Oct 2021
Publication
Through its “Reducing Carbon whilst Creating Social Value: How to get Started’ initiative Welsh Government is keen to explore whether a ‘circular economy’ (and industry) could be developed for Wales for CO2.Although most companies have targets to reduce their CO2 by 2030 Wales does not have the space to store or bury any excess with the current choice to ship or ‘move the problem’ elsewhere. Meanwhile other industry sectors in Wales are experien Read More
Hydrogen adsorption on transition metal carbides
Jan 2019
Publication
Transition metal carbides are a class of materials widely known for both their interesting physical properties and catalytic activity. In this work we have used plane-wave DFT methods to study the interaction with increasing amounts of molecular hydrogen on the low-index surfaces of four major carbides – TiC VC ZrC and NbC. Adsorption is found to be generally exothermic and occurs predominantly on the surface carbon atoms. We identify trends over the Read More
A Study of Decrease Burst Strength on Compressed-hydrogen Containers by Drop Test
Sep 2019
Publication
We investigate an appropriate initial burst pressure of compressed hydrogen containers that correlates with a residual burst pressure requirement at the end of life (EOL) and report an influence of hydraulic sequential tests on residual burst pressure. Results indicate that a container damage caused by a drop test during hydraulic sequential tests has a large influence on burst pressure. The container damage induced through hydraulic sequential tests is inve Read More
The Energy Approach to the Evaluation of Hydrogen Effect on the Damage Accumulation
Aug 2019
Publication
The energy approach for determining the durability of structural elements at high temperature creep and hydrogen activity was proposed. It has been shown that the approach significantly simplifies research compared with the known ones. Approbation of the approach was carried out on the example of determining the indicators of durability of the Bridgman sample under conditions of creep and different levels of hydrogenation of the metal. It wa Read More
Advances in Reforming and Partial Oxidation of Hydrocarbons for Hydrogen Production and Fuel Cell Applications

Pathways to Low-cost Clean Hydrogen Production with Gas Switching Reforming
Feb 2020
Publication
Gas switching reforming (GSR) is a promising technology for natural gas reforming with inherent CO2 capture. Like conventional steam methane reforming (SMR) GSR can be integrated with CO2 -gas shift and pressure swing adsorption units for pure hydrogen production. The resulting GSR-H2 process concept was techno-economically assessed in this study. Results showed that GSR-H2 can achieve 96% CO2 capture at a CO2 avoidance cost of 15 $/ton (i Read More
