“…Hydrogen, when produced from renewable biomass sources, has been regarded as an ideal energy carrier for the sustainable energy development [1][2][3][4][5][6][7][8]. Among the various biomass-derived feedstocks, bio-ethanol is considered as one of the most promising alternatives because of its relatively high hydrogen content, availability and non-toxicity [9,10].…”

“…A renewable hydrogen system comprises an electrolyser, a hydrogen storage tank and a fuel cell as their main components. The electrolyser is powered by the excess electricity generated by the renewables and produces hydrogen through the electrolysis of water [4,5]. The hydrogen produced by the electrolyser gets stored conveniently in a storage tank for example.…”

“…Alkaline electrolyzers are determined to be the most suitable for the considered application for their scale of hydrogen flow rate, efficiencies, and relatively low capital costs. Olateju and Kumar (2011) and Olateji et al (2014) conducted two studies on the techno-economic evaluation of electrolytic hydrogen production from wind energy for the upgrading operations of bitumen from oil sands. This system would have virtually no GHG emissions during operation.…”

a b s t r a c tAn energy optimization model for the integration of renewable technologies into the energy infrastructure of the oil sands industry is presented. The proposed model determines the optimal configuration of oil producers and the energy infrastructure required to meet their energy demands. The model is geared toward the minimization of cost subject to carbon dioxide emission constraints. A mixed integer non-linear optimization model is developed that simultaneously optimizes capacity expansion and new investment decisions of conventional and renewable energy technologies. To illustrate its applicability, the proposed model was applied to a case study using data reported in the literature for various years of oil sands operations. A rolling horizon approach was implemented to determine the effect of investment decisions of previous operational years on the selection of new investment options. Results were compared with and without the incorporation of renewable energy technologies. The results obtained indicate that the proposed model is a practical tool that can be employed to evaluate and plan oil sands and energy producers for future scenarios. Moreover, the results show that renewable energy technologies have significant potential in reducing reliance on fossil-fuel based technologies and their associated CO 2 emissions. The emission constraints set for the operational year 2025 can only be achieved by the incorporation of renewables in the energy production mix. (A. Elkamel). its viscosity for further transportation to be sold as commercial crude bitumen or to be upgraded to higher quality synthetic crude oil (SCO). Bitumen upgrading operations can be integrated with mining or steam assisted gravity drainage (SAGD) extraction operations, and they typically consist of hydrocracking or thermocracking processes to break the heavy hydrocarbon molecules into lighter ones. Mining extraction is typically employed for bitumen deposits located at depths up to 75 m. The oil sands are mined by electric and hydraulic shovels, which are then transported by trucks to separation units in which hot water and solvents are used to extract the bitumen from the oil sands mixture. In-situ methods are used for deep bitumen deposits that are located more than 75 m below the earth's surface, and they have been employed to recover deposits at depths within the range of 350-600 m below the surface. In-situ methods rely on the use of steam, solvents or thermal energy to extract the bitumen from the oil sands in order to enhance its flow, which is then pumped to the surface. The two prominent production technologies are mining and in-situ, the latter being more economically and environmentally preferable and will account to approximately two-thirds of future oil sands production capacity. Mining extraction is currently the dominant method used for bitumen extraction (
