Water desalination and sustainable energy harvesting are among the greatest challenges of our society, and nanofluidics offers promising solutions to address them. Nanofluidic energy conversion systems rely on electrokinetic (EK) effects, which couple different types of transport (hydrodynamic, elec
An experimental and numerical study of a novel active online mixing and heat transfer device for yield stress fluids encountered in food industry is proposed. Simple dimensional arguments indicate that, by reducing the effective length of the active mixer, one gains quadratically in the energy neede
Electric power generation is one of the major issues in the context of eco-responsible economic developments. According to the U.S. Department of Energy, by 2040, natural gas (for gas turbines) and renewables would be the top two fuel types for electricity generation. Natural gas and renewables woul
It is now widely accepted that the continuous global warming of the atmosphere observed in the last 150 years is due to an increase in the atmospheric concentrations of greenhouse gases, and that the storage of carbon dioxide (CO2) in deep geological formations is the only feasible medium term solut
The production of synthetic fuels (H2, syngas, liquid fuels) is a major challenge, in particular when produced from clean and novel renewable processes without any fossil resources. The reduction of CO2 emissions requires a strong decrease of fossil energy utilization while developing CO2-free renew
A multi-disciplinary approach leads to a better understanding of the subsurface. This is in particular true for high temperature geothermal energy: the construction of geological bodies, discontinuities, high contrast in the physical properties, wide range of variation for thermodynamic conditions…
Gas-solid fluidized beds are widely used in processes for energy. In all these processes the short-range (van der Waals forces) and medium-range (electrostatic) particle-particle interaction forces may have a strong influence and reduce the operation energetic efficiency. In these processes elec
This project deals with the valorisation of lignin, which is a by-product of the pulp and paper industry, into phenolic compounds by a thermochemical process with new catalysts. Phenol is an important building block for the chemical industry notably to produce polymers. This project is a good exampl
The project concerns the understanding of dissipation phenomena in turbulence and the possibility that they are partly related to possible singularities. These phenomena, still poorly understood at the theoretical level, have direct consequences on the production or consumption of energy, in particu
CO2 recycling is a major environmental, economical and societal priority. Carbon capture technologies have improved significantly and instead of being a waste, CO2 could become a raw material for a “green” organic chemistry or fuel production. Many techniques are investigated to achieve an efficient
The demand for ultra-clean alternative fuels and chemicals produced from biomass has been rapidly growing around the world. The fundamental target of this research project deals with the design of novel nanoreactor systems with encapsulated metal nanoparticles and processes for the sustainable direc
Pc2TES aims at developing a new kind of materials with high potential for cost-effective compact thermal energy storage (TES) at high temperature. The proposal is based on a ground-breaking idea which consists in using chemical compounds formed during peritectic transitions. The term peritectic refe
FRAISE project intends to optimize energy conversion through falling-film absorption processes. Its main technological outcome is the development of innovative concepts for the design of efficient desorbers, which represents the bottleneck for the conception of new compact absorption machines adapt
