Tuning energy transport in solar thermal systems using nanostructured materials
Solar thermal energy conversion can harness the entire solar spectrum and theoretically achieve very high efficiencies while interfacing with thermal storage or back-up systems for dispatchable power generation. Nanostructured materials allow us to tune the spectral properties and heat transfer …

Adsorption at the nanoparticle interface for increased thermal capacity in solar thermal systems
In concentrated solar power (CSP) systems, high temperature heat transfer fluids (HTFs) are responsible for collecting energy from the sun at the solar receiver and transporting it to the turbine where steam is produced and electricity is generated. Unfortunately, many high temperature HTFs have …

Monitoring and anomaly detection in solar thermal systems using adaptive resonance theory neural networks
SHW systems are generally expected to last for at least 20 years with little or no maintenance. However, in many cases failures occur far sooner due to a variety of problems, many of which are undetected or detected long after the system has failed because the backup heater silently assumes the …

Energy recovery at thermodynamic expansion and thermal boosting through convection in flat plate solar thermal systems.
… demands. Due to inexhaustible amount of clean solar energy, engineers and researchers are engaged in developing technologies to minimise dependency on fossil fuels. Solar collectors are utilised to use solar heat to increase the heat energy of thermo-fluids or heat transfer fluid (HTF), which …

Radiative transport in transparent aerogels for solar thermal energy applications
Solar-thermal energy conversion systems hold great promise to meet our diverse energy demand by a renewable source. Converting sunlight into thermal energy requires solar radiation to be absorbed and transformed into heat effectively while minimizing system thermal loss to the ambient environment. …

Improvements to solar thermoelectric generators through device design
A solar thermoelectric generator (STEG) is a device which converts sunlight into electricity through the thermoelectric effect. A STEG is nominally formed when a thermoelectric generator (TEG), a type of solid state heat engine, is placed between a solar absorber and a heat sink. When the solar …

An investigation into the performance of a very shallow borehole thermal energy store for a solar-assisted ground source heat pump
… heating needs at lower energy costs. Likewise, solar thermal systems have been integrated into conventional GSHP to reduce the size of the ground heat exchanger and provide seasonal heat storage. So far, this technology has mainly been used in large commercial or residential buildings due to its …

Improving solar thermal receiver performance via spectral and directional selectivity
… climate change. Among renewable energy sources, solar energy conversion systems are particularly promising due to the abundance of solar energy reaching Earth. Despite its abundance, the solar resource is dilute, so solar energy must be collected efficiently in order for it to meet an appreciable …

Measurement of optical properties of molten salts and metallic compounds for advanced solar and nuclear systems
… can reduce the dependence on fossil fuels. Solar thermal systems designed to use molten salts to directly absorb the solar heat are promising due to (1) potentially higher efficiency in capture of sunlight and (2) use of the salt to simultaneously capture sunlight and store heat in the salt. …

Performance analysis and modelling of hybrid photovoltaic-thermal solar panels
<p>A photovoltaic-thermal (PVT) panel was constructed, tested, and modelled using both MATLAB and TRNSYS. During the experimental testing, which took place on the Missouri University of Science and Technology campus in Rolla, Missouri; two identical PVT panels were tested alongside two PV panels to …
