On the Assessment of the CO2 Mitigation Potential of Woody Biomass

François Richard Vuille, François Maréchal, Emanuela Peduzzi, Victor Codina Gironès

Woody biomass, a renewable energy resource, accumulates solar energy in form of carbon hydrates produced from atmospheric CO2 and H2O. It is, therefore, a means of CO2 mitigation for society as long as the biogenic carbon released to the atmosphere when de ...

Multi-objective optimization of a sugarcane biorefinery for integrated ethanol and methanol production

François Maréchal, Emanuela Peduzzi, Adriano Viana Ensinas, Priscilla Caliandro, Sandro Onorati

The present study evaluates a sugarcane biorefinery producing ethanol through juice fermentation and methanol via gasification of sugarcane lignocellulosic residues and liquid fuel synthesis. Two technologies of gasification named entrained flow and circul ...

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

François Maréchal, Emanuela Peduzzi, Victor Codina Gironès, Stefano Moret, 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 ...

Multi-objective Optimization of Solid Oxide Fuel Cell–Gas Turbine Hybrid Cycle and Uncertainty Analysis

François Maréchal, Emanuela Peduzzi, Ayse Dilan Celebi, Shivom Sharma

Chemical process optimization problems often have multiple and conflicting objectives, such as capital cost, operating cost, production cost, profit, energy consumption and environmental impact. There are several conversion technologies that can convert Sy ...

Biomass Modelling: estimating thermodynamic properties from the elemental composition

François Maréchal, Emanuela Peduzzi, Guillaume Boissonnet

In the context of modelling biomass conversion processes, the accurate representation of biomass, which is a complex and highly variable material, is of crucial importance. This study provides a rather simple and flexible way to represent biomass, especial ...

Integration of deep geothermal energy and woody biomass conversion pathways in urban systems

François Maréchal, Léda Gerber, Emanuela Peduzzi, Stefano Moret

Urban systems account for about two-thirds of global primary energy consumption and energy-related greenhouse gas emissions, with a projected increasing trend. Deep geothermal energy and woody biomass can be used for the production of heat, electricity and ...

Investment and production costs of synthetic fuels - A literature survey

Emanuela Peduzzi, Guillaume Boissonnet

Synthetic fuels, or synfuels, can be produced from gas, coal and biomass. The conversion of gas and coal is well established but lignocellulosic biomass conversion is slow to develop. This paper addresses the issue of the production cost of second generati ...
