Renewable energy integration and waste heat valorization in aluminum remelting for co-producing kerosene and methanol
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos, Réginald Germanier
The aluminium sector relies on natural gas for the conversion of recycled scrap into new feedstock, which results in substantial atmospheric emissions. Hydric resources are also impacted, as they serve as heat sinks for the waste heat generated during the ...
2024On the prediction of the induced damage by the start-up sequence of Francis turbines: On operational resilience framework
Mario Paolone, Christophe Nicolet, Elena Vagnoni, Martin Seydoux
The number of transient operations in hydraulic machinery connected to power grid, notably start-ups and shut-downs, has observed a substantial increase in recent decades, primarily driven by the global shift toward intermittent renewable energy sources. S ...
2024Performance 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 ...
2024Decarbonizing the fertilizers sector: an alternative pathway for urea and nitric acid production
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
In order to alleviate the environmental impact that nitrogen fertilizers production is responsible for, several efforts have been addressed to incentivize the partial or total decarbonization of the supply chains of ammonia and its derivatives. The decarbo ...
2024Beyond the average consumer: Mapping the potential of demand-side management among patterns of appliance usage
Claudia Rebeca Binder Signer, Selin Yilmaz, Matteo Barsanti
To support the decarbonisation of the power sector and offset the volatility of a system with high levels of renewables, there is growing interest in residential Demand-Side Management (DSM) solutions. Traditional DSM strategies require consumers to active ...
2024Advanced control strategies to exploit the hydropower potential enhancing ancillary services provision to the power system
The European Union's Green Deal aims for a 55% reduction in greenhouse gas emissions by 2030. To reach this goal, a massive integration of Renewable Energy Sources (RES) into the power grid is necessary. As RES become a large part of the electricity genera ...
EPFL2024Perspective Alkaline electrolyzers: Powering industries and overcoming fundamental challenges
For the sustainable development of the renewable hydrogen sector, alkaline electrolysis appears to be a technology of choice. Nevertheless, despite its long history that showed its reliability in the industrial field and despite the traditional belief from ...
Cell Press2024CO2 Capture and Management Strategies for Decarbonizing Secondary Aluminium Production
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos, Réginald Germanier
The production of aluminium largely depends on the use of fossil fuels, resulting in the emission of significant amounts of greenhouse gases. As the aluminium industry is working towards decreasing its environmental burdens, the elimination of direct emiss ...
2024Design and Synthesis of Bio-based Amphiphiles from Lignocellulosic Biomass
In the pursuit of a carbon-neutral chemical industry, minimizing fossil feedstock consumption while integrating renewable carbon sources is imperative. Surfactants, inherently amphiphilic, pose challenges in separation and recovery processes. Given their e ...
