Efforts to characterize geothermal supply have long been focused on the aspect of power generation [Petty, et al., 1992], [Petty, et al., 2007], and [Augustine, et al., 2010]. This paper focuses on an approach to characterize the supply curve of hydrogeothermal energy that can be used for direct use in the United States. It aims to compensate for the absence of research on thermal uses and prov...

Power systems for South and Central America based on 100% renewable energy (RE) in the year 2030 were calculated for the first time using an hourly resolved energy model. The region was subdivided into 15 sub-regions. Four different scenarios were considered: three according to different high voltage direct current (HVDC) transmission grid development levels (region, country, area-wide) and one...

We assess the implications on long-run average energy production costs and emissions of CO2 and some criteria pollutants from coupling wind, solar and natural gas generation sources. We utilize five-minute meteorological data from a US location that has been estimated to have both high-quality wind and solar resources, to simulate production of a coupled generation system that produces a consta...

Studies of the future competitiveness of reverse electrodialysis (RED) with other energy technologies show that the projected levelized cost of electricity realized through current stack designs is prohibitively high. Despite these high projected costs, RED maintains other advantages namely, the harnessing of a renewable and non-intermittent energy resource, the emissions-free operation, the di...

For remote places having less-strong wind, single resources based renewable energy system (RES) with battery storage can sustainably and economically generate electrical energy. There is hardly any literature on optimal sizing of such RES for very low load demand situation. The objective of this study is to techno-economically optimize the system design of a Photovoltaic (PV)-battery storage RE...
