Silicon protected with atomic layer deposited TiO2: durability studies of photocathodic H-2 evolution

The semiconducting materials used for photoelectrochemical (PEC) water splitting must withstand the corrosive nature of the aqueous electrolyte over long time scales in order to be a viable option for large scale solar energy conversion. Here we demonstrat ...

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 ...

Thermodynamics and the optimisation of energy systems: Strengths and Limits

Daniel Favrat

The Second Law of thermodynamics is known to be an essential guide for the improvement of energy conversion systems. Throughout the years it has been applied to various engineering methods in particular in methods based on exergy [1] including the 2nd Law, ...

Effect of groundwater flow on the THM behavior of an energy pile

Lyesse Laloui, Fabrice Dupray, Mélanie Baehler

Bridges are one of the road structures that are most exposed to icing, a problem that is widely dealt with through salting, a technique that reduce the lifespan of the bridge. Seasonal storage of solar heat energy captured directly through the asphalt laye ...

Pore fluid in experimental calcite-bearing faults: Abrupt weakening and geochemical signature of co-seismic processes

Marie Estelle Solange Violay

While it is widely recognized that fluids influence fault strength and earthquake nucleation, propagation and arrest, their effects on co-seismic sliding friction are only conjectured. To shed light on these effects, 55 high velocity (>1ms-1) friction e ...

Draft tube discharge fluctuation during self-sustained pressure surge: fluorescent particle image velocimetry in two-phase flow

François Avellan, Andres Müller, Nicolas Andreini, Matthieu Dreyer

Hydraulic machines play an increasingly important role in providing a secondary energy reserve for the integration of renewable energy sources in the existing power grid. This requires a significant extension of their usual operating range, involving the p ...

Identifying champion nanostructures for solar water-splitting

Michael Graetzel, Francesco Stellacci, Cécile Hébert, Kislon Voitchovsky, Maurin Cornuz, Scott Charles Warren

Charge transport in nanoparticle-based materials underlies many emerging energy-conversion technologies, yet assessing the impact of nanometre-scale structure on charge transport across micrometre-scale distances remains a challenge. Here we develop an app ...

Isothermal transcritical CO2 cycles with TES (thermal energy storage) for electricity storage

Daniel Favrat, Young Min Kim

Recently, TEES (thermo-electric energy storage) systems have been proposed as a new method for large-scale energy storage wherein electric power is stored as thermal energy by using a heat pump and retrieved from the TES (thermal energy storage) by using a ...
