Hydrogen Bubble Dispersion and Surface Bursting Behaviour
Sep 2013
Publication
In many processes where hydrogen may be released from below a liquid surface there has been concern regarding how such releases might ultimately disperse in an ullage space. Knowledge of the extent and persistence of any flammable volume formed is needed for hazardous area classification as well as for validation of explosion modelling or experiments. Following an initial release of hydrogen the overall process can be subdivided into three stag Read More
Innovation Insights Brief: Energy Scenarios Comparison Review
Apr 2019
Publication
Energy transition is a part of a much wider Grand Transition which is not all about energy. Energy transition cannot be achieved all at once or by any one actor. Relying only on better energy modelling and forecasting to guide successful transition will be fatal even in a data-rich era.It is timely for energy leaders to ask:Are global energy scenarios achieving their potential in opening up action on new energy futures?How do the Council’s World Energy Scena Read More
Technologies and Infrastructures Underpinning Future CO2 Value Chains: A Comprehensive Review and Comparative Analysis
Feb 2018
Publication
In addition to carbon capture and storage efforts are also being focussed on using captured CO2 both directly as a working fluid and in chemical conversion processes as a key strategy for mitigating climate change and achieving resource efficiency. These processes require large amounts of energy which should come from sustainable and ideally renewable sources. A strong value chain is required to support the production of valuable products from CO2 . Read More
Reversible Ammonia-based and Liquid Organic Hydrogen Carriers for High-density Hydrogen Storage: Recent Progress
Feb 2019

Performance Evaluation of Empirical Models for Vented Lean Hydrogen Explosions
Sep 2017
Publication
Explosion venting is a method commonly used to prevent or minimize damage to an enclosure caused by an accidental explosion. An estimate of the maximum overpressure generated though explosion is an important parameter in the design of the vents. Various engineering models (Bauwens et al. 2012 Molkov and Bragin 2015) and European (EN 14994 ) and USA standards (NFPA 68) are available to predict such overpressure. In this study their pe Read More

A Simple Model for Calculating Peak Pressure in Vented Explosions of Hydrogen and Hydrocarbons
Apr 2019
Publication
The authors presented a basic mathematical model for estimating peak overpressure attained in vented explosions of hydrogen in a previous study (Sinha et al. [1]). The model focussed on idealized cases of hydrogen and was not applicable for realistic accidental scenarios like presence of obstacles initial turbulent mixture etc. In the present study the underlying framework of the model is reformulated to overcome these limitations. The flame shape computa Read More
The Influence of Refractory Metals on the Hydrogen Storage Characteristics of FeTi-based Alloys Prepared by Suspended Droplet Alloying
Jun 2020

The influence of the addition of refractory metals (molybdenum and tantalum) on the hydrogenation properties of FeTi intermetallic phase-based alloys was investigated. The suspended droplet alloying technique was applied to fabricate FeTiTa-based and FeTiMo-based alloys. The phase composition and hydrogen storage properties of the samples were investigated. The samples modified with the refractory metals exhibited lower plateau pressures and lowe Read More

Hydrogen for Heating? Decarbonization Options for Households in the United Kingdom in 2050
Dec 2020
Publication
The heating sector makes up 10% of the United Kingdom’s carbon footprint and residential homes account for a majority of demand. At present central heating from a natural gas-fired boiler is the most common system in the UK but low or zero-carbon hydrogen and renewable electricity are the two primary energy replacement options to reduce the carbon footprint. An important consideration is how using either energy source would affect heating co Read More
