A hybrid power plant including a solar central receiver for receiving solar radiation and converting it to thermal energy. The power plant includes a molten salt heat transfer medium for transferring the thermal energy to heat exchanger. The use of fossil fuels should be reduced in near future due to their limited resources and increasing ecological impacts. Therefore, increased interest and incentives have been created for development of electricity supply utilizing renewable energy such solar energy, which has long-range potential and is applicable in most geographical regions Libya is located in the center of North Africa. The vast majority of the country is located in the Sahara Desert, which is characterized by its high potential for solar energy. This study provides an evaluation study for the solar power plant with a capacity equal to 70 GW/year to support generating electricity. The System Advisor Model (SAM) model system, developed by the National Office of Renewable Energy (NRE), was used to assess the plant's active and economic performance.
Tripoli City, the Capital of the Libya, has experienced far-reaching changes in spatial and socio-economic patterns during the last few decades, supported by crude oil revenue. The changes have produced far-reaching increase in municipal solid waste (MSW) generation and electricity demand. Open landfilling is the dominant method of MSW disposal in the city. This research aims to assess the value of Waste-to-Energy (WTE) facility as a solution to MSW landfill problem and as a renewable source of electricity. two WTE scenarios were developed: complete incineration; incineration with recycling. The results show that Tripoli has the potential to produce about 57 MW of electricity based on incineration scenario; about 32 MW based on incineration with recycling scenario; in the year 2030. These values are based on theoretical ideals and help in identifying the optimal WTE techniques for each city.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
