A hybrid solar energy system consisting of a molecular thermal storage (MOST) combined with water heating (SWH) is presented.
The global trends for the rapid growth of distributed solar heat and power in last decade will likely continue as levelized cost production these technologies continues to decline. To be able compare economic potential one must first quantify types amount resource that each technology can utilize; second, estimate technological performance based on resource; third, costs across regions. In this analysis, we have performed two steps process. We use physical empirically validated models a...
We report on life cycle assessment (LCA) of the economics, global warming potential and water (both for desalination use in operation) a distributed concentrating solar combined heat power (DCS-CHP) system. Detailed simulation system performance across 1020 sites US with sensible cost allocation scheme informs this LCA. forecast levelized $0.25 kWh−1 electricity $0.03 thermal, ∼80 gCO2eq ∼10 sited Oakland, California.

This paper investigates the cost-effectiveness of operation strategies which can be used to abate CO 2 emissions in a local multi-energy system. A case study is carried out using data from real energy system that integrates district heating, cooling, and electricity networks at Chalmers University Technology. Operation are developed mixed integer linear programming multi-objective optimization model with short foresight rolling horizon year data. The different evaluated across carbon prices....
The European roadmap for the power sector dictates an 80–95% cut of existing levels carbon dioxide emissions is needed by year 2050 to meet climate goals. This article describes results from a linear cost optimization investment model, ELIN, coupled with solar technology Distributed Concentrating Solar Combined Heat and Power (DCS-CHP), using published costs comprehensive suite renewable conventional electricity generation technologies, compare possible scenarios future grid. these model...
A small, efficient, and robust turbine is essential to the development of a small-scale (∼10 kWe) Combined Heat Power (CHP) Rankine cycle system. While Tesla design offers versatile solution with low manufacturing maintenance cost, its successful use in systems this type hinges on that also high energy conversion efficiency. The investigation summarized here explored parametric trends efficiency using model analysis performance tandem experimental testing small scale turbine. data were used...
Abstract In this article, we present performance results and analysis of a novel rotary lobe expander device. This is part larger research effort into the design small‐scale solar system that would compete with available distributed technologies for heat electricity generation. To choose an appropriate working fluid components concentrating combined power (DCS‐CHP) system, compared many different fluids, collectors, choices. Of expanders analyzed, including piston expanders, radial inflow...
Solar combined heat and power (CHP) systems can compete or exceed solar photovoltaics (PV) — which is often used as the benchmark in terms of efficiency, performance, cost a range distributed generation applications, across specific technology platforms. A common metric to evaluate per peak output “dollars watt” metric. For purpose comparison, we develop new analytic methodology electricity generated from CHP system. The thermal subsystems system are energetically intertwined, yet by...
Recent studies suggest that small scale (5–10kW) distributed solar Rankine combined heat and power could be a viable renewable energy strategy for displacing fossil fuel use in residential buildings, commercial or developing rural communities. One of the primary obstacles scaling down technology to this level is finding an appropriate expander design. This paper considers radial-inflow turbine such application. Although well-tested methodologies exist design analysis radial inflow turbines,...
