Integration of Solar Energy In The Development of Palms Irrigation System And Long-Term Bio-Ethanol Production In the South of Algeria
During the history, the economy of Ouargla city and surrounding (in south of Algeria) is based on date palms. These trees are very resistant to hot climate and their dates are rich in sucrose substance, so they are considered as promoter candidates for ethanol production. Promoting this potential necessarily involves cost reduction of agriculture palms; mainly the irrigation cost should be decreased. The application of a photovoltaic pumping system on medium well operating can achieve a payback period not exceeding at least 15 years even if grid extension cost is not included. The investigation by using Arcgis software shows that Ouargla basin has in important underground water sources with high flow rates and low depths. The wide flat area around this city allows huge agriculture expansion to develop a profitable bio-ethanol industry. In this work, ethanol extraction is limited to waste dates as row material. For 2013, the bio-ethanol extraction from only three date varieties (Ghers, Deglet-Nour and Deglet-Beida) is estimates about 23,500 liters, by using a trend model it can reach 148,500 and 648,500 liters in 2018 and 2038 respectively. The estimation by a voluntary model by taking into account an exploitation rate as 80% of reserved agriculture land, forecasting bio-ethanol production will be at least quadruple.
