The effects of bismuth and tin on the mechanochemical processing of aluminum-based composites for hydrogen generation purposes
(Elsevier, 2019)The work described in this paper forms part of a study on the mechanochemical processing of Al with dissimilar metals for hydrogen generation purposes. Here, in an effort to contain the cost of the activation of Al, we ... -
A highly efficient autothermal microchannel reactor for ammonia decomposition: analysis of hydrogen production in transient and steady-state regimes
(Elsevier, 2018)The experimental evaluation of an autothermal microchannel reactor for H2 production from NH3 decomposition is described. The reactor design incorporates an autothermal approach, with added NH3 oxidation, for coupled heat ... -
Hydrogen generation by means of hydrolysis using activated Al-In-Bi-Sn composites for electrochemical energy applications
(ESG, 2017)Effective activation compounds are developed to produce hydrogen via hydrolysis of ball-milled Al-In-Bi-Sn composites in tap water at room temperature. Al-In-Bi-Sn composites are successfully activated by 3 h of milling. ... -
Hydrogen generation by the hydrolysis of mechanochemically activated aluminum-tin-indium composites in pure water
(Elsevier, 2018)This paper presents results of our continuing project on the mechanochemical activation of Al-based composites for hydrogen generation [1,2]. A series of bi- and ternary Al, Sn, and/or In composites were mechanochemically ... -
Hydrogen generation of mechanochemically activated Al-Bi-In composites
(Elsevier, 2017)The individual and combined effects of Bi and In on the morphology change and reactivity towards hydrogen release of Al during mechanochemical preparation of binary and ternary Al composites were determined. Subsequently, ... -
A modelling evaluation of an ammonia-fuelled microchannel reformer for hydrogen generation
(Elsevier, 2014)Hydrogen production from an ammonia-fuelled microchannel reactor is simulated in a three-dimensional (3D) model implemented via Comsol Multiphysics™. The work described in this paper endeavours to obtain a mathematical ... -
Power management and sizing optimisation of renewable energy hydrogen production systems
(Elsevier, 2019)This paper presents the combined sizing and power management optimisation methodology for a small-scale stand-alone hybrid renewable energy (RE) hydrogen production system. System cost is argued to be dependent on efficiency ...
