Its main scope is to produce an assessment of the chances, risks and expected benefits of the concentrating solar power (CSP) technology, with emphasis given to socio-economic and environmental aspects for the Mediterranean region. For this purpose, after providing an overview of the CSP technologies and analyzing the configuration of CSP plants, the socio-economic impact derived from CSP technology and the various environmental impacts were examined. In addition an overview of the CSP market worldwide and the potential implementation of CSP technology in some Mediterranean countries were presented. Consequently, various case studies were analyzed to evaluate impact of aspects like use of land and water, use of hybrid RES systems and also thermal storage applications. Finally, a sensitivity analysis was performed to assess the financial viability of a CSP plant in Mediterranean region under various preconditions. Τhe study and comprehension of such an innovative and complex technology as CSP systems combined with the various aspects affected is a quite demanding with a high level of difficulty process that requires an extensive knowledge in many scientific fields, such as a good knowledge of fundamentals of solar thermal systems but also a good knowledge in fundamentals in investment appraisals. So at this point I would like to express my sincere regards to my supervisor, Prof. Agis Papadopoulos for his contribution and his guidance during the actualization of the present dissertation.

    An application of pinch analysis in the design of a stand-alone thermochemical cycle, hydrogen hub sourced from renewables in rural South Africa By Daniel Cecil Seragie Thesis submitted in fulfilment of the requirements for the degree Master of Engineering: Chemical Engineering In the Faculty of Engineering At the Cape Peninsula University of Technology Supervisor: Mr. Joe John Co-Supervisor: Prof Daniel Ikhu-Omoregbe Bellville Campus May 2020 CPUT copyright information The dissertation/thesis may not be published either in part (in scholarly, scientific or technical journals), or as a whole (as a monograph), unless permission has been obtained from the University DECLARATION I, Daniel Cecil Seragie, declare that the contents of this dissertation/thesis represent my unaided work and that the dissertation/thesis has not previously been submitted for academic examination towards any qualification. Furthermore, it represents my own opinions and not necessarily those of the Cape Peninsula University of Technology. Signed Date i | P a g e ABSTRACT Economic and social development are closely related to the accessibility of electricity. Meanwhile, non- grid connected rural areas shoulder the burden of health and environmental risks since extending the grid is considered uneconomical. Renewable hydrogen, hybrid energy systems are viewed as a promising solution in remote areas where grid extension is costly and fuel costs increase parallel to remoteness. Hence, this study applies heat and power pinch analysis in the conceptual design of an isolated, decentralized thermochemical cycle hydrogen & biogas energy hybrid, to satiate the electricity needs of a non-grid rural area in South Africa. This study highlights the value of using heat pinch and PoPA tools as a mid-term supplement to combat increasing energy costs, reduce negative environmental impacts, improve profits, and more importantly as a contribution to ensuring temperatures are kept well below 2℃ above pre-industrial levels.

  • Potential of Renewable Energy Resources with an Emphasis on Solar Power in Iraq: an Outlook
    resources Viewpoint Potential of Renewable Energy Resources with an Emphasis on Solar Power in Iraq: An Outlook Hussain H. Al-Kayiem * and Sanan T. Mohammad Mechanical Engineering Department, Universiti Teknologi PETRONAS, Seri Iskandar 32610, Perak, Malaysia; [email protected] * Correspondence: [email protected]; Tel.: +60-14-300-1591 Received: 25 January 2019; Accepted: 20 February 2019; Published: 25 February 2019 Abstract: This study presents an outlook on the renewable energies in Iraq, and the potential for deploying concentrated solar power technologies to support power generation in Iraq. Solar energy has not been sufficiently utilized at present in Iraq. However, this energy source can play an important role in energy production in Iraq, as the global solar radiation ranging from 2000 kWh/m2 to a 2500 kWh/m2 annual daily average. In addition, the study presents the limited current solar energy activities in Iraq. The attempts of the Iraqi government to utilize solar energy are also presented. Two approaches for utilizing concentrated solar power have been proposed, to support existing thermal power generation, with the possibility of being implemented as standalone plants or being integrated with thermal power plants. However, the cost analysis has shown that for 50 kW concentrated solar power in Iraq, the cost is around 0.23 US cent/kWh without integration with energy storage. Additionally, notable obstacles and barriers bounding the utilization of solar energy are also discussed. Finally, this study proposes initiatives that can be adopted by the Iraqi government to support the use of renewable energy resources in general, and solar energy in particular.

Dr. Mükerrem ŞAHİN ÖZET Enerji talebindeki artış ve elektrik üretimi için kullanılan fosil yakıtların rezervlerinin azalması günümüzde enerji açısından en büyük endişe kaynağıdır. Yenilenebilir enerji kaynaklarının kullanılması bu sorunların üstesinden gelmek için en iyi seçenek olarak kabul edilebilmektedir. Güneş enerjisi, elektrik ve ısı üretmek için en önemli yenilenebilir enerji kaynaklarından biridir. Elektrik üretimi, deniz suyunu tuzdan arındırma, iklimlendirme ve sıcak su temini için güneş enerjili termal sistemler kullanılmaktadır. Güneş enerjisi sistemlerinde ısı transfer sürecinin iyileştirilmesi en önemli konulardan biridir. Bu ise kompakt tasarımlı sistemlerin daha iyi performans gösterebilmesi için gelişmiş termo-fiziksel özelliklere sahip çalışma akışkanları tasarlanarak ve üretilerek başarılabilir. Yoğunlaştırılmış güneş enerjisi (CSP) sistemlerinde en çok kullanılan akışkanlardan biri olan solar tuzun termal özelliklerini geliştirmek için yapılan bu tezde katkı malzemesi olarak amorf B2O3, camsı B2O3 ve hegzagonal bor nitrür kullanılmıştır. Solar tuz referans olarak kullanılmış ve %0,5, %1 ve %2 oranlarında katkı malzemeleri ayrı ayrı konularak erime noktası, kütle kaybı ve ısı kapasitesi analizleri yapılmıştır. En umut verici değerlere %2 hegzagonal bor nitrür içeren numunede ulaşılmıştır.
