Anisotropic In-Plane strain engineering Ni(OH)2 to activate alkaline hydrogen evolution reaction

Realizing a hydrogen economy strongly requires alkaline water electrolysis to achieve large-scale generation of H2, but lacks stable and efficient catalysts. The insufficient active sites in Ni(OH)2 impair the catalytic performance of alkaline HER. Herein, ...

Insights into the interaction of a shale with CO2

Lyesse Laloui, Eleni Stavropoulou

Caprock formations, such as shales, play a key role in safe underground CO2 storage since they serve as a hydromechanical barrier that prevents migration of the injected CO2 to the surface. While their hydromechanical response is important to ensure their ...

Scenario modelling and optimisation of renewable energy integration for the energy transition

Victor Codina Gironès

A large number of countries have engaged themselves in an energy transition towards more re- newable energy in their energy systems. Motivations stem mainly from the need to reduce CO2 emissions, and from a desire of their population to phase out technolog ...

Multi-objective optimization of turbo-ORC systems for waste heat recovery on passenger car engines

Jürg Alexander Schiffmann, Eliott Philippe Guenat, Violette Mounier, Kévin Rosset

Waste heat recovery from passenger car internal combustion engines by means of an organic Rankine cycle (ORC) system is promising for reducing CO2 emissions. In this study, different cycle configurations capable of converting waste heat from both coolant a ...

Spatial clustering for district heating integration in urban energy systems: application to geothermal energy

François Maréchal, Stéphane Joost, Stefano Moret, Jérémy Michel Pierre Unternährer

Given the challenges related to climate change and dependency from fossil fuels, modification of the energy systems infrastructure to increase the share of renewable energy is a priority in urban energy planning. The high heating density in cities makes it ...

Winter ecology of a subalpine grassland: Effects of snow removal on soil respiration, microbial structure and function

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills

Seasonal snow cover provides essential insulation for mountain ecosystems, but expected changes in precipitation patterns and snow cover duration due to global warming can influence the activity of soil microbial communities. In turn, these changes have th ...

Carbon Capture and Storage: introductory lecture

Berend Smit

Carbon Capture and Storage ( CCS) is the only available technology that allows us to significantly reduce our CO2 emissions while keeping up with the ever-increasing global energy demand. Research in CCS focuses on reducing the costs of carbon capture and ...

Bioconversion of sugarcane crop residue for value added products - An overview

Edgard Gnansounou

Sugarcane is a major crop cultivated globally and the residue left over after the crop harvest and extraction of juice is a good biomass source that can be used for the production of several useful chemicals. The sugarcane bagasse is an excellent substrate ...

Integration of Organic Rankine Cycles for Waste Heat Recovery in Industrial Processes

Matthias Bendig

Developing a methodology that allows identifying maximumelectricity production with the help of Organic Rankine Cycles (ORC) from the waste heat of an industrial process, at the lowest specific cost, without jeopardising the increase of the industrial proc ...

Identifying and modeling the integrated design process of net Zero Energy buildings

Emmanuel Walter, Marilyne Andersen, Shady Galal Mohamed Attia

High Performance Buildings (HPB), including Net Zero Energy Buildings (NZEBs) and nearly Zero Energy Buildings (nZEB) are emerging as an important market in Europe and around the world. However, there are very few studies that aim to model the process of H ...

Methodology for the optimal thermo-economic, multi-objective design of thermochemical fuel production from biomass

François Maréchal, Martin Gassner

This paper addresses a methodology for the optimal conceptual design of thermochemical fuel production processes from biomass. A decomposed modelling approach with separate energy-flow, energy-integration and economic models is presented and coupled to mul ...

Non-GMO approach for the improvement of heavy metal accumulation and extraction of high yielding crop species for efficient phytoextraction of contaminated soil

Erika Nehnevajova

Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
