Solar-assisted clean steam generator, a cleaner production approach for sustainable healthcare facilities
Fernando Porté Agel, Mohammad Jamshidmofid, Ahmad Arabkoohsar
Healthcare sector buildings, particularly hospitals, significantly contribute to global energy consumption and greenhouse gas emissions. Hospitals require a substantial amount of steam, including the essential hygienic or " clean steam, " that is currently ...
Elsevier Sci Ltd2024Performance of energy piles foundation in hot-dominated climate: A case study in Dubai
Lyesse Laloui, Elena Ravera, Sofie Elaine ten Bosch
Energy piles represent an innovative technology that can help provide sustainable geothermal heating or cooling energy for thermal conditioning purposes. In hot-dominated climates, the interest is to inject heat in the ground and extract energy for space-c ...
2024Performance gap in the building sector and its impact on investment decisions for heating requirements
Between the ideal and reality lies the decisive world of the performance gap. This project is conducted within the framework of a Master Thesis at the Industrial Processes and Energy Systems Engineering (IPESE) laboratory of Ecole Polytechnique F´ed´erale ...
2024Decomposition method to evaluate district heating/cooling network potential at urban scale
François Maréchal, Luc Girardin, Ana Catarina Gouveia Braz, Bingqian Liu, Raphaël Briguet
In this work, a tool to design district heating networks (DHN) is presented and applied to the city of Lausanne as a case study. The evaluation of the buildings’ heat/cooling demand is performed using a Geographic Information System (GIS) database, built f ...
Associazione Italiana Di Ingegneria Chimica2024Shaped Laser Pulses for Microsecond Time-Resolved Cryo-EM: Outrunning Crystallization during Flash Melting
Marcel Drabbels, Constantin Richard Krüger, Nathan Junior Mowry
Water vitrifies if cooled at rates above 3 × 105 K/s. In contrast, when the resulting amorphous ice is flash heated, crystallization occurs even at a more than 10 times higher heating rate, as we have recently shown. This may present an issue for microseco ...
2024Single-Well Pore Pressure Preconditioning for Enhanced Geothermal System Stimulation
Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, Barnaby Padraig Fryer
The stress state is an important parameter in terms of both earthquake nucleation and rupture. Here, a new stimulation technique is proposed for Enhanced Geothermal Systems (EGSs), which have previously been burdened with a number of high-profile incidence ...
AMER GEOPHYSICAL UNION2023A fully-coupled highly-parallelized geomechanical simulator for assessing induced seismicity
Jean-François Molinari, Brice Tanguy Alphonse Lecampion, Guillaume Anciaux, Nicolas Richart, Emil Gallyamov
Induced seismicity caused by anthropogenic modification of the subsurface effective stress state has been observed in a number of industrial applications -- from hydrocarbon extraction (e.g., Groningen [1]), drilling waste-water disposal (e.g., [2]) to the ...
2023Fluid flow through microcracked and fractured granitic reservoirs
Marie Estelle Solange Violay, Lucille Jocelyne Nadine Carbillet, Michael Heap
The permeability of crustal rocks and rock-masses dictates the efficiency of hydrothermal circulation and therefore the productivity of geothermal resources. In this study, we find by monitoring P-wave velocity that thermal microcracking in Lanhélin granit ...
2023Reactivation of variably sealed joints and permeability enhancement in geothermal reservoir rocks
Alexandra Roma Larisa Kushnir, Michael Heap
Hydraulic stimulation of enhanced deep geothermal reservoirs commonly targets pre-existing joint networks with the goal of increasing reservoir permeability. Here, we study the permeability and strength of joint-free and jointed Buntsandstein sandstones fr ...
2023Permeability, alteration, and microstructure: A (hopefully) coupled rock physics and geochemical approach to how rock-fluid interactions change permeability
Permeability is a key physical property across all spatial scales in the Earth’s crust and exerts significant control on the behaviour of Earth systems, with implications for natural hazards (e.g., earthquakes, slope instabilities, volcanic eruptions) and ...
