6686 Youness El Fouih and Chakib Bouallou / Energy Procedia 37 (2013) 6679 – 6686 3.5 t of CO2 and 5 t of H2O to produce 1 ton of ethanol, which means that more than 21 000 t of CO2 and 300 000 t of water vapor are consumed each year. The total primary energy consumption rises to 109.8 MJ per 1 kg of ethanol, which is more than the energy consumption of the usual ethanol production processes. Due to lack of experience feedback, the economic analysis of the whole process was carried out using cost estimating assumptions based on pilot plant costs and similar processes costs. The results of the economic analysis demonstrated that the ethanol production plant driven by a high-temperature nuclear power plant can deliver ethanol at a cost of $1.1/kg, assuming an internal rate of return on investment of 8%. This final cost could be lowered if we consider the co-production of methane and hydrogen. Also, if we take into account oil price increase and the subsidies it is estimated that this process can be competitive with other conventional methods of producing ethanol in the next 10 to 15 years.
