    Production and areas of use of gas biofuels and optimization of bioprocess parameters affecting the production efficiency
    (Batman Üniversitesi, 2018-12-27) Dursun, Nesrin; Gülşen, Hakkı
    The importance of renewable energy sources is increasing day by day due to the reasons such as fossil fuel reserves being on the point of exhaustion and trying to minimize the negative effects thereof on the environment. In biogas processes, hydrogen and carbondioxide gases are released through the degradation of organic matters by acidogenic bacteria with fermentation and the conversion thereof into organic acids. In the second stage, organic acids are transformed into acetic acid, hydrogen and carbondioxide by acidogenic bacteria. While methane bacteria use the hydrogen they need, they also remove the hydrogen that affects the acidogenic bacteria negatively. Biohydrogen production processes, on the other hand, the system is processed by applying heat pretreatment to anaerobic fermentation bacteria for 20-45 mins and between 90-105 0 C. In the first stage, organic wastes with high carbohydrate ratio are degraded by heat pretreated anaerobic fermentation bacteria into organic acids, hydrogen and carbondioxide. In the second stage, the organic acids produced in the first stage are degraded to hydrogen and carbondioxide with fermentative bacteria. In this study, optimization of the bioprocess parameters affecting the production, use and production efficiency of gas biofuels is presented.

    Wind power potential and usage in the coastal regions of Turkey
    (Journals & Books, 2015-04) Aydın, Hüseyin; İlkılıç, Cumali
    In this study, the potential of wind power in the coastal areas of Turkey have been studied. Current potential of the wind energy in coastal areas and its usage in Turkey have been investigated. The main purpose of this study is to investigate the wind energy plants in coastal regions of Black Sea, Marmara, Aegean and Mediterranean regions and project in Turkey. The wind energy potentials of all regions in Turkey have been investigated and utilization of the wind energy in coastal regions of Turkey was also studied. Various regions have been analyzed by taking wind data into account that had been measured in hourly time series in the windy locations. The coastal regions of Aegean, Marmara and East-Mediterranean have high wind energy potentials and wind densities. The wind data used in this study have been obtained taken from Electrical Power Resources Survey and Development Administration (EIEI) of Turkey. Istanbul, Izmir, Datça, Bandırma, Antakya, Çanakkale and Hatay areas have been found to be the most promising areas for wind energy systems with their wind densities. Sinop, Gökçeada, and Mersin follows these areas. It can be suggested the there are many suitable areas, for wind energy applications and investments, especially many of them are clustered in coastal regions in Turkey.

    Examination of renewable energy sources in Batman
    (Bitlis Eren Üniversitesi, 2017) Kallioğlu, Mehmet Ali; Avcı, Ali Serkan; Ercan, Umut; Kıstak, Celal
    Nowadays, there is a rapid increase in demand for energy in Turkey. For this reason, it is very important to use renewable energy sources for potential high, clean and continuous ones. Batman province should make more use of renewable energy sources according to its geographical position. Among these energy sources are sun, wind, biomass, geothermal energy. Although it has a potential above the average of Batman province in terms of solar energy, it is not used at a sufficient level. It has a potential of about 1580 kWh / m2 . Hydraulic energy has a very high power of about 250 MW. It also has a wind energy potential of 7,92 MW. But there is no power plant because the wind cannot provide the necessary conditions for energy. Another source of energy, biomass energy, has 69.618,95 TOE (tons of oil equivalent) / year of energy supply, but no plant exists. A similar situation also applies to the source of geothermal energy. Batman province does not have active geothermal energy facilities. This study investigated the current state of the renewable energy resources in Batman and its more efficient use.
