Hot water generation for oil sands processing from enhanced geothermal systems: Process simulation for different hydraulic fracturing scenarios
Hofmann, Hannes; Babadagli, Tayfun; Zimmermann, Günter - In: Applied Energy 113 (2014) C, pp. 524-547
The oil sands in northern Alberta, Canada are home to one of the largest hydrocarbon deposits on earth. Huge amounts of hot water—around 50–60°C—are needed for the current extraction procedure and processing technology. The current practice of obtaining water from the Athabasca River and...

Life cycle assessment of hydrogen production from underground coal gasification
Verma, Aman; Kumar, Amit - In: Applied Energy 147 (2015) C, pp. 556-568
Western Canada is endowed with considerable reserves of deep un-mineable coal, which can be converted to syngas by means of a gasification process called underground coal gasification (UCG). The syngas can be transformed into hydrogen (H2) through commercially available technologies employed in...

Land demand for ethanol production
Leal, Manoel Regis L.V.; Horta Nogueira, Luiz A.; … - In: Applied Energy 102 (2013) C, pp. 266-271
Several key indicators of the sustainability of biofuels are related to the land used to produce the feedstock. Most of the agronomic costs and energy use (fertilizers, herbicides, soil preparation, and harvesting) are more related to the cropped area than to the feedstock quantity produced; this...
