Harvesting the full spectrum of sunlight using a hybrid approach offers the potential for higher efficiencies, lower power production costs, and increased power grid compatibility than any single technology by itself. In this article, the base technologies for converting sunlight into electricity, including photovoltaics and solar thermal approaches are discussed. Then feasible strategies for c...

We introduce the concept of nuclear battery, a standardized, factory-fabricated, road transportable, plug-and-play micro-reactor. Nuclear batteries have potential to provide on-demand, carbon-free, economic, resilient, and safe energy for distributed heat electricity applications in every sector economy. The cost targets these markets are 20–50 USD/MWht (6–15 USD/MMBTU) 70–115 USD/MWhe electric...

This study is aimed at scrutinizing the domestic solar energy potential for electricity and hydrogen production. Under first scenario, it sought to evaluate generation household purposes using RSUs (rooftop units). Then, under second production analyzed purpose of meeting a vehicle demand. For this, one aptest cities, Yazd, located in center Iran investigated. Furthermore, real-world electric l...

Renewable Energy Sources are still in continual progress to be used for electricity production, the most important of which is Concentrated Solar Energy, has played a prominent role during past years production. However, focusing on economic aspect remains ensure implementation these projects, as many countries focus necessary cost investing projects and resulting from modern technologies. In t...

This study presents a techno-economic analysis of mini-grid solar photovoltaic system for five typical rural communities in Chad while promoting renewable energy systems adaptation and electrification. The assessment techniques include the establishment socio-economic state through field survey. costs development, electricity tariff sizing production are realised via Levelized Cost Electricity ...

With the increasing penetration of renewable energy sources and energy storage devices in the power system, it is important to evaluate the cost of the system by using Levelized Cost of Energy (LCOE). In this paper a new metric, Levelized Cost of Delivery (LCOD) is proposed to calculate the LCOE for the energy storage. The recent definitions in LCOE for renewable energy system has been reviewed...

We examine the economic feasibility of using dedicated DC circuits to operate lighting in commercial buildings. We compare light-emitting diodes (LEDs) and fluorescents that are powered by either a central DC power supply or traditional AC grid electricity, with and without solar photovoltaics (PV) and battery back-up. Using DOE performance targets for LEDs and solar PV, we find that by 2012 LE...

In this paper, the annual and economic performance of an integrated solar combined cycle (ISCC) with indirect energy storage tanks is investigated. The study includes four scenarios, in which the combined cycle performance was studied exclusively in the first scenario. In the second scenario, the integrated solar combined cycle (ISCC) was examined, and the use of supplementary firing instead of...

This paper is an update of an earlier supply analysis, He, et al., (2013), of low-temperature utilization of geothermal resources using geothermal district heating and cooling systems. Along with the use of identified hydrothermal resources, it updates the supply curve for direct-use utilization using undiscovered hydrothermal resources and near-hydrothermal EGS resources. It also incorporates ...
