Global energy demand increases every day due to growing needs. The ideal of eco-friendly, sustainable and low cost energy generation relying on countries’ own domestic sources increases the interest in renewable energy in the 21st century. However, the intermittent nature of the renewable energy brings the importance of and the need for energy storage to surface. Pumped storage hydroelectricity (PSH) has been in use worldwide for a long time with this purpose thanks to its large scale storage capacity and proven technology. Unlike many countries with pumped storage, Turkey has not needed a PSH facility until very recently in virtue of its significant hydropower capacity. Wind and solar power share in Turkey’s electrical grid has increased so far and the first nuclear power plant of the country is planned to start operating in 2023, thus leading to advancement in energy storage and PSH. The high investment costs and long construction period of PSH lead to some significant questions for a projected pumped storage facility in Turkey: technical features, location, investment costs, model, operation initiation day, etc. In this dissertation, potential profitability/unprofitability of a projected PSH facility in Turkey is examined. Within this scope, in order to analyze the requirement for PSH in Turkey, the country’s electricity system and market are discussed in detail and compared with countries that have pumped storage. Evaluations are made using real time electricity prices and generation-consumption values through the perspective of both public and private sector. Results show that the current prices in Turkish electricity market are not profitable enough to attract investment by the private sector.

Recently, renewable energy resources are getting more important day by day since energy demand of the world is continuously increasing. One of the promised renewable energy sources is wave energy as the water covers more than 70% of the world. Moreover, Turkey is an esteemed country with the high potential to exploit from wave energy as it is surrounded with seas and also Turkey has been searching for proper solutions in order to satisfy energy demands from past to now. In this regard, there are many studie...
Feasibility of biomass heating system in Middle East Technical University, Northern Cyprus Campus
Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (Informa UK Limited, 2016-01-01)
Global interest in using biomass feedstock to produce heat and power is increasing. In this study, RETScreen modelling software was used to investigate the feasibility of biomass heating system in Middle East Technical University, Northern Cyprus Campus. Weiss Kessel Multicratboiler system with 2 MW capacity using rice straw biomass as fuel and 10 units of RBI (R) CB0500 boilers with 144 kW capacity using natural gas as fuel were selected for the proposed biomass heating system. The total cost of the biomas...
Green energy for the battlefield
Aslan, Murat; Isik, Halil (2017-01-01)
Population of the world is growing with increasing rate and it seems that existing fossil fuel energy sources will not be able to meet energy demand in the near future. Energy is not only crucial for civil sector but also it is one of the most important assets in defense sector. Energy for military operations is mostly provided from fossil fuel as it is the case in other sectors; however, fossil fuels have hazardous effects to the environment and cause global environment concerns. These drawbacks of fossil ...
Optimal corrosion prevention in crude oil refineries with surrogate modeling
Yandık, Yücelen Bahadır; Koçyiğit, Altan; Department of Information Systems (2020-9)
Energy demand in the world is increasing day by day, which makes energy markets extremely competitive. Crude oil refineries have to adapt to this competition like other players in the energy field. Corrosion is a common problem in crude oil refineries. Production may need to be stopped for maintenance to fix problems caused by corrosion. These stops cause businesses to miss their production target and lose their competitive advantage. Today, it is known that the salts in crude oil play an important ro...
Development of a methodology for sizing and assessment of wind integrated advanced adiabatic compressed air energy storage system (aa-caes)
Taştankaya, Koray; Tarı, İlker; Baker, Derek Keıth; Department of Mechanical Engineering (2014)
Renewable energy usage has become widespread and gained world-wide importance lately. In order to get high quality power from renewable energy sources to the grid, bulk energy storage system will be required as a buffer, due to the intermittent nature of renewable energy. Advanced adiabatic compressed air energy storage (AA-CAES) technology is uniquely different from conventional energy storage techniques for renewable energy in that it captures and stores the heat generated during the compression cycle and...
