Preliminary techno-economic, environmental and risk assessments of a hybrid solarised gas turbine concept

In the power generation sector, substituting fossil-fuels with near-zero carbon alternatives is one viable option identified for curbing CO2 emissions. Solar energy is one such alternative and it's valued for being inexhaustible in nature. This study exami ...

Thermo-Economic Modelling and Process Integration of CO2-Mitigation Options on Oil and Gas Platforms

François Maréchal, Tuong-Van Nguyen, Laurence Tock

The offshore extraction of oil and gas is an energy-intensive process associated with large CO2 and CH4 emissions to the atmosphere and chemicals to the sea. The taxation of these emissions has encouraged the development of more energy-efficient and enviro ...

Technologies for gas turbine power generation with CO2 mitigation

François Maréchal

A review of the state of the art gas turbine power plants designs with CO2 capture was performed to set up a list of technologies to be considered in a conceptual process superstructure. It has been found that the efficiency and economics of carbon dioxide ...

Elsevier2011

New EU and US emissions regulations require the development of advanced after- treatment systems for non-road diesel engine exhausts. To help develop these at Liebherr Machines Bulle, the use of CFD has been adopted. The pro ject used two main models: one ...

Études d'options énergétiques pour le quartier "Etraz-Sud"

François Maréchal, Luc Girardin

L'étude de scénarios pour le quartier Etraz-Sud permet de conclure qu'en recommandant un chauffage à basse température et un standard énergétique élevé pour les nouveau bâtiments, il sera possible de profiter des ressources locales avec des pompes à chaleu ...
