  • Exergetic and sustainability performance assessment of geothermal (ground source) ejector heat pumps

    Although ejectors have been used in cooling/refrigeration and Heat Pumps (HP) applications for a long time, utilisation of Geothermal Ejector Heat Pump (GEHP) with Ground–Heat Exchanger (GHE) is a new idea, which has recently appeared in the literature. In this study, we model a GEHP system with a GHE in terms of exergetic aspects and apply our model to this system in the heating mode. The system ...

  • Bio-SNG featured in energy world in February 2011

    The use of bio-fuels for heating and lighting pre-dates the use of fossil fuels by thousands of years. However, unlike with fossil fuels, a systematic knowledge of the challenges posed by solid bio-fuels is not as widely understood, a fact attributable to the exponential acceleration of fossil fuel usage as global demand increased during the industrial revolution. In the wake of this, producers ...

  • SGBI opinion article: shale gas

    Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...
