Optimal use of biomass in large-scale energy systems: insights for energy policy

François Maréchal, Stefano Moret, Emanuela Peduzzi, Victor Codina Gironès, Marco Nasato

Biomass chemical conversion processes allow the production of solid, liquid and gaseous biofuels, which can substitute almost any kind of fossil fuel and the associated greenhouse gas emissions. Despite this potential, high investment costs and conversion ...

Environmental, Energetic and Economic Evaluation of Implementing a Supercritical Fluid-Based Nanocellulose Production Process in a Sugarcane Biorefinery

François Maréchal, Juliana Queiroz Albarelli

Nanocellulose, which is a disintegration product of plant cellulose, has recently come to public attention because of its great mechanical properties combined with renewability and biodegradability. From an environmental point-of-view, nanocellulose has sh ...

Modeling and Optimization of an Industrial Ammonia Synthesis Unit: An Exergy Approach

Daniel Alexander Florez Orrego

An exergy modeling and optimization of an industrial ammonia unit based on steam methane reforming (SMR) process is presented. The base-case unit produces about 1000 t NH3/day [1], as well as power and steam, with no auxiliary exergy use. Some critical ope ...

Optimisation of unit investment and load shedding in a steam network facing undercapacity

François Maréchal, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener

Steam networks and their utilities should be dimensioned to satisfy day-to-day demand as well peaks. Peaks can be caused by unit start-ups, extreme weather conditions or combinations of high demand from process units. During maintenance operations or unexp ...

Geothermal energy integration in urban systems. The case study of the city of Lausanne.

Frédéric Louis-Pierre Raphaël Marie Amblard

In the framework of the GEOTHERM II, a joint effort of geoscience, engineering and social-science of academic and public partners, the integration of geothermal energy in urban systems is evaluated. A superstructure was defined for the case study of the ci ...

Performance and profitability perspectives of a CO2 based district energy network in Geneva's City Centre

François Maréchal, Daniel Favrat, Céline Weber, Samuel Henchoz

A new type of district energy network providing simultaneously heating and cooling services is being investigated. It is based on the use of CO2 as a heat transfer fluid by taking advantage of the latent heat of vaporization, to store and transfer heat acr ...

On the physical mechanisms governing self-excited pressure surge in Francis turbines

François Avellan, Arthur Tristan Favrel, Christian Landry, Andres Müller, Keita Yamamoto

The required operating range for hydraulic machines is continually extended in an effort to integrate renewable energy sources with unsteady power outputs into the existing electrical grid. The off-design operation however brings forth unfavorable flow pat ...
