Highlights Carbon dioxide/Silicon Tetrachloride mixture is proposed as innovative working fluid. Bubble points and liquid densities of the mixture are experimentally obtained. The experimental data are used for the fine-tuning of the equation of state. The thermodynamic efficiency of the mixture is simulated in next-generation CSP plant. The mixtur...
To enable the widespread exploitation of intermittent, low-cost, and non-dispatchable renewable energy technologies, energy storage plays a key role in providing the required flexibility. This study introduces maps of optimal combination of Thermal Energy Storage (TES) and power cycles, supporting decision-making in power-to-heat-to-power applicati...
This study aimed to investigate the potential of supercritical carbon dioxide (sCO2), organic Rankine cycle (ORC), and thermoelectric generator (TEG) systems for application in automotive exhaust waste heat recovery (WHR) applications. More specifically, this paper focuses on heavy-duty diesel engines applications such as marine, trucks, and locomo...
With a goal to increase the percentage of grid energy produced by renewable sources, research and development efforts in solar, wind, and geothermal resources are progressing rapidly. In this work, the use of concentrated solar thermal power for energy production and thermal energy storage is presented for the supercritical carbon dioxide (sCO2) Br...

As a first step in evaluating materials for a concentrated solar power (CSP), supercritical CO2 Brayton cycle, experiments are being conducted to simulate the daily operating cycle using 10-h thermal cycles in 1 bar CO2 at 700–800 °C. After 1000-h exposures, the mass gains for commercial Ni-base alloys 740H, 282, 625 and Fe-base alloy 25 were relat...
