The consumption of primary energy is often used to compare energy systems from a sustainability viewpoint at regional, national or even world level. For such comparisons to be “fair” and meaningful, this implies however to define primary energies in a cohe ...
As energy plays a central role in the world development, it represents as well a major challenge for sustainable development. Today, more than 80% of the primary energy consumption is based on fossil fuels and the share is likely to remain high in the futu ...

Methodologies developed for the analysis, improvement and optimization of energy systems must take into account not only energy use (exergy consumption) and financial resources expended (economics), but the scarcity both present and future of all resources ...
Exergy concept combined with pinch based approach are used for studying the optimal integration of energy conversion systems. The analysis first considers the representation of the hot and cold composite curves of the process and defines the energy and the ...
In 1998, the Board of the Swiss Federal Institute of Technology established the challenging vision of the 2000 W society. The goal is to reach, for Switzerland by the year 2050, an energy intensity target of 2000 Wyear/year/cap. Referring to a present inte ...
A method for the analysis of process energy requirements has been used to identify in an early design stage the potential process retrofit measures in an integrated pulp and paper mill. The minimum energy requirements (MER) of the process were computed by ...

This paper presents results for the minimization of fuel consumption in a batch furnace. Several different criteria are used and minimized with respect to time-dependent process and control variables. The results show that globally there is no significant ...
Biogas as renewable source of energy is underexploited. We extrapolate the potential recoverable from waste streams in the EU-15 to 769 PJ (17.5 Mtoe), of which under 10% is used (1.7 Mtoe). SOFC can promote the valorisation of biogas in small CHP installa ...
