Today a strong and rising demand of energy is known because of the technological evolution in various sectors. In order to reduce greenhouse gas emissions from this energy production, the foremost nations have prioritized the development strategies of resources and energy systems that preserve the environment. In this thesis, a hybrid renewable energy system based on a combination of sustainable and fossil resources with an integration of the new "Power to Gas" concept was developed to explore the feasibility as well as the reliability of this system in a determined location in Algeria. This system consists of a solar and wind resource as well as a Micro Gas Turbine to supply variable power consumption while the excess energy is converted and stored as a gas either Hydrogen or Methane that will be used during production falls to compensate for the deficiency of energy. The management of this system is one of the most important factors which have led to the introduction of artificial intelligence techniques which is known by the fuzzy logic that ensures efficient performance for this system
Carbone dioxide capture and utilization in gas turbine plants via the integration of power to gas
(Elsevier, 2017) Boubenia, Ahmed; Hafaifa, Ahmed; Kouzou, Abdellah
Recent studies have shown that the concentration of greenhouse gases such as carbon dioxide in the atmosphere is growing rapidly over recent years and this can lead to major dangers for the planet. This growth is mainly due to the emissions from fossil power source such as diesel plants and gas turbines. The purpose of the present paper is to study the feasibility of integrating a technique based on power to gas concept in fossil power plants such as gas turbine. This work is based on the reduction of pollutant gas emissions produced from a gas turbine plant, especially the carbon dioxide. This captured gas (CO2) can be converted once again into energy via the technique of power to gas concept. This concept starts by extracting CO2 from exhaust gases which is carried out by multiple chemical process. On the other side, H2 is produced from water electrolysis using the excess electricity which is produced but not consumed by the existing loads. finally the production of Methane (CH4) can be achieved by combination of the captured CO2 and the extracted H2 via a reactor known as a reactor of Sabatier, this operation is called methanation or hydrogenation of carbon dioxide. Simulation results are presented for the validation of the proposed technique based on real data obtained on site from a gas turbine plant. Copyright © 2016, Southwest Petroleum University.

Modeling of a Small Scale Wind Turbine for Water Pumping Process: case study
(L&H Scientific Publishing, 2018) Boubenia, Ahmed; Hafaifa, Ahmed; Guemana, Mouloud; Kouzou, Abdellah; Becherif, Mohamed
This paper deals with the study of a small scale wind turbine implementation for agricultural isolated location. Indeed, the electrification of these locations for industrial and agricultural requirements remains one of the largest current projects, especially when dealing with the use of sustainable sources such as solar, hydro and wind power. The main aim of this work is to validate the feasibility of using wind turbine in this location and to evaluate the performance of the excess energy storage capacity, which in this case is stored as water under the potential energy form. The study represented in this paper has been performed under the case of pumping water station using wind turbine in an isolated location at the north of Algeria, considering that this site fulfills the requirement of a favorable wind potential and a permanent water source. The design of the used wind turbine is based on the constraints of the climate data of the selected location and the lower cost of the implementation means, whereas, the water tank dimensions are is optimized with respect to the daily water consumption data and the available excess of energy to be stored and to be used later for water pumping during the period of wind absence
