Integrated solar-driven high-temperature electrolysis operating with concentrated irradiation

Jan Van Herle, Sophia Haussener, Stefan Diethelm, Clemens Gregor Suter, Meng Lin

High-temperature electrolysis for reducing H2O (and CO2) to H2 (and CO) converts concentrated solar energy into fuels and chemical feedstock. We invented an integrated reactor concept comprising a solar cavity receiver for reactant heating, a solid oxide e ...

Optical and structural analysis of sol-gel derived Cu-Co-Mn-Si oxides for black selective solar nanocomposite multilayered coatings

Andreas Schueler, Aïcha Hessler-Wyser, Marina Aymara González Lazo, Pierre Loesch, Martin Python, Olivia Valérie Charlotte Bouvard, Martin Joly, Yannik Antonetti, Thomas Gascou

In this paper, we report the preparation of the precursor solutions for the deposition of Cu-Co-Mn-Si oxides by a sot-gel method in order to produce black selective coatings for CSP receiver tubes. Their optical properties were investigated by means of spe ...

Thermo-economic optimisation of large solar tower power plants

Germain Augsburger

Given the growing number of solar tower power plants in operation, under construction and under planning, the assessment and the optimisation of their performance are required both at the energy level and the economic level. In other words, the same way as ...

Multi-Scale Modelling of a Solar Reactor for the High-Temperature Step of a Sulphur-Iodine-Based Water Splitting Cycle

Sophia Haussener, Aldo Steinfeld

The 3-step sulphur-iodine-based thermochemical cycle for splitting water is considered. The high-temperature step consists of the evaporation, decomposition, and reduction of H2SO4 to SO2 using concentrated solar process heat. This step is followed by the ...

Thermoeconomic optimization of a combined-cycle solar tower power plant

Daniel Favrat, Germain Augsburger, James Spelling

A dynamic model of a pure-solar combined-cycle power plant has been developed in order to allow determination of the thermodynamic and economic performance of the plant for a variety of operating conditions and superstructure layouts. The model was then us ...

Performances et limites de chaudières à gaz de centrales solaires

Production of electricity from solar energy is mainly achieved by means of solar cells or by central receiver power plants. These plants are driven by vapor turbines where the fluid temperature is about l000°F or by gas turbines in which gas temperature ex ...
