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 ...

Renewable and non-renewable exergy costs and CO2 emissions in the production of fuels for Brazilian transportation sector

An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...

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 ...

Villigen PSI, World Resources Forum, printed by Paul Scherrer Institute2015

Impacts of emissions changes from four potential U.S. CO2 emission reduction policies on 2050 air quality are analyzed using the community multiscale air quality model (CMAQ). Future meteorology was downscaled from the Goddard Institute for Spac ...

Measurement of Leaf Area Index for Calculation of Water Consumption by Agroforestry Trees in Burkina Faso

Pierre-Adil Abdelmoula

(français dessous) Measurements of leaf area index (LAI), solar radiation under canopy, sap flow and soil humidity were made on a Marula tree (Sclerocarya birrea) in the commune of Madjoari, South-East of Burkina Faso, at the end of the rainy season of the ...
