Solar thermal and biomass combustion systems can be hybridized via a Rankine cycle to have a continuous electricity generation and lower CO2 footprint. Disadvantages of these two renewable technologies can be overcome by hybridization. In this work; we develop a simulation model for Rankine cycle based, solar-biomass hybrid power plants using the ASPEN PLUS software. Solar parabolic collectors and biomass combustion are arranged in parallel to produce steam for power generation. Using the simulation model; thermal efficiency, fuel consumption rate, CO2 emissions are investigated for 1 MW and 5 MW installed capacities. Besides, a financial analysis is conducted via MS EXCEL software. In the financial analysis, Net Present Value (NPV) and Internal Rate of Return (IRR) are calculated for both 1 MW and 5 MW installed capacities. According to the results, hybridization reduces biomass consumption by 18% and CO2 emission by 20% compare to a stand-alone biomass power plant with the same installed capacity. IRR is calculated as 15.64% for 80% debt financing scenario.

Conceptual design and heat transfer investigation of a dense granular flow solar receiver
Johnson, Evan Fair; Baker, Derek Keıth; Tarı, İlker; Department of Mechanical Engineering (2017)
Solid particles have previously been proposed as an alternative to molten salt as a heat transfer and heat storage medium for concentrating solar power plants. While previous solid particle solar receiver designs use fluidized or falling particles, the new type of receiver proposed in this thesis uses a gravity-driven flow of particles in a dense granular flow regime. Through experimentation with sand, the flow and heat transfer properties were studied in two geometries: vertical tubular and vertical parall...
Numerical investigation of circulating fluidized bed riser hydrodynamics for concentrating solar thermal receiver applications
Bilyaz, Serhat; Tarı, İlker; Department of Mechanical Engineering (2015)
Various heat transfer fluids and thermal storage materials are considered for concentrating solar power systems to improve the storage capability of the system which compensates the fluctuating behavior of the solar resources. Solid particles can be a good alternative since they have high sensible heat capacity. In addition, they are cheap, environmentally benign and chemically and mechanically stable at high temperatures. In this thesis, hydrodynamics of circulating fluidized bed solar receiver was numeric...
Modelling and performance analysis of linear fresnel collector for process heat generation for ice cream factory in Konya
Singh, Rahul; Baker, Derek Keıth; Tarı, İlker; Department of Mechanical Engineering (2017)
In this thesis, a linear Fresnel collector has been designed to supply solar heat for industrial process. Firstly, optical analysis using ray tracing is done to determine the effects of collector’s parameters, such as height of receiver, mirror width and profile, gap between adjacent rows and slope deviation. Afterwards, one-dimensional thermal model is presented which predicts surface temperatures of receiver components and heat loss. The results obtained from both optical and thermal studies are then benc...
Preliminary Study on Site Selection For Floating Hybrid Wind And Solar Energy Systems In Turkey
Yerlikaya, Nevzat Can; Çakan, Çağatay; Başara, Ilgın; Caceoğlu, Eray; Huvaj Sarıhan, Nejan (2021-09-08)
It is well-known that even though fossil fuels are the main energy resource in Turkey, use of sustainable energy resources such as wind and solar energy has been increasing in the past years and expected to continue on this trend in the next years to come. The suitable land for land-based wind turbines and photovoltaic (PV) systems could also be convenient for various other purposes, such as agriculture. This study aims to investigate the suitable sites for a combined floating wind and solar systems in the ...
Numerical simulations of gas production from Class 1 hydrate and Class 3 hydrate in the Nile Delta of the Mediterranean Sea
MEREY, ŞÜKRÜ; Longinos, Sotirios Nik (Elsevier BV, 2018-04-01)
Gas hydrate reservoirs are considered as near-future energy resources in the world. As well as the many places in the world, there is also gas hydrate potential in the Mediterranean Sea. In this study, by using the literature data, it was aimed to understand whether the Mediterranean Sea includes necessary parameters for producible gas hydrate reservoirs. It was shown that the Mediterranean Sea contains all of these parameters (source gas, appropriate pressure and temperature, coarse sand potential, etc.). ...
