Abstract
In this study, the applicability of pressure retarded osmosis power generation was investigated in order to meet the electricity demand in Turkey. Pressure retarded osmosis (PRO) is a method that converting salinity gradients to power using a semi-permeable membrane against an applied pressure and PRO is one of the promising candidates to reduce fossil fuel dependency. In PRO, water is transported from a low concentrated feed solution to a high-concentrated draw solution. According to the literature findings, in order to produce 1MW of electricity 1m3/s fresh water flow is needed. Turkey is surrounded on three sides by water and has a big potential to develop this technology. Riva River is investigated in the scope this study. Currently Turkey’s total installed power capacity reached 85.200 MW at the end of 2017.Calculations of PRO power generation reveals that it is possible to generate 25,45 MW, If using 5% of total river flow.
Highlights
Global energy consumption mainly depending on fossil fuels which are resulting an increase of climate change
When we investigated Turkey’s renewable energy potential from wind energy plant, It is calculated with the assumption that 5MW power plant can be installed with 50m altitude and wind speeds above 7.5m / s with the General Directorate of Renewable Energy (YEGM)
Electricity generation of selected river basins was calculated according to Eq
Summary
Global energy consumption mainly depending on fossil fuels which are resulting an increase of climate change. Turkey’s total electricity (power) demand has been increasing rapidly and it reached 264 TWh in 2015. According to the Energy and Natural Resources Ministry data Turkey added 5.840 MW of new electricity production in 2017 with $6.2 billion total investments. With this newly added electricity generation Turkey’s total installed power capacity reached 85.200 MW at the end of 2017 [Url-3]. Istanbul (Asian Side) total production capacity is 25.1 MW and this energy depends on natural gas [Url-6]. Riva River, known as Çayağzı Stream, is a stream located in the Kocaeli Peninsula, north of the Marmara Region It is born near the Tepecik village of Gebze district of Kocaeli province and enters into the borders of Istanbul province. RO membranes were found unsuitable for PRO applications because of severe concentration polarization [7], [8]
