Urea as a hydrogen carrier: a perspective on its potential for safe, sustainable and long-term energy supply
Recently, there have been publications reporting the use of urea, as a source of hydrogen/fuel cell power. There have however been no reports that singularly assess the suitability of urea for this… Expand

  • Proceedings of the Royal Society A: Mathematical…
  • 1 August 2016
The correlation between thermochemical provenance and biochar functionality is poorly understood. To this end, operational reactor temperatures (spanning the reduction zone), pressure and product gas… Expand

Thermodynamics of hydrogen production from urea by steam reforming with and without in-situ carbon-dioxide sorption.
Abstract The thermodynamic effects of molar steam to carbon ratio (S:C), of pressure, and of having CaO present on the H 2 yield and enthalpy balance of urea steam reforming were investigated. At a… Expand

Hydrogen from urea–water and ammonia–water solutions
Abstract The conversion of urea–water into hydrogen was investigated in a downward flow packed-bed reactor using a Ni–Al2O3 catalyst. This was conducted at atmospheric pressure under molar steam to… Expand

Thermogravimetric evolved gas analysis of urea and urea solutions with nickel alumina catalyst
Abstract Thermal decomposition of urea, and aqueous urea solutions, in the presence of 18 wt % nickel on alumina was studied by thermogravimetric analysis. A range of evolved gas species (a wider… Expand
