Simulating the use of biomass in electricity with the green electricity simulate model: An application to the French power generation

Bertrand, Vincent; Le Cadre, Elodie - Chaire d'Économie du Climat, Université … - 2015

This paper presents the version 1.0 of the Green Electricity Simulate (GES), which is a simulation model that has been … biomass co-firing in coal plants. We extend previous works in essentially three directions. We provide the first simulation … model for electricity taking into account co-firing with a wide range of induced effects. Second, we analyze the impact of …

Analysis of the World Market for Steam Coal Using a Complementarity Model

Haftendorn, Clemens; Holz, Franziska - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008

With its resource availability and the prospect of climate friendly technology, coal continues to play an important role in the global energy sector. We develop a complementarity model of the international market for steam coal. We want to analyze the level of competition in this market which is...
