In urban areas, the use of thermal energy services is intensive and relatively heterogeneous by their nature, spatial distribution and temperature level required. In this study three concepts of district energy networks that could provide these services ve ...
The present report describes the method used for the computation and integration of the energy system which has been built within this semester. All the supplying energy technologies , which have been taken into account are presented. The fundamental equat ...
A two stage dry-wet anaerobic digestion system pilot project, fed with the Organic Fraction of Municipal Solid Waste (OFMSW) of a municipality of Antioquia, Colombia, is being developed. The system produces as byproducts: biogas with high methane content ( ...

The most exploited renewable energy at a global scale is hydropower, which nowadays accounts for the 18 % of the world’s electricity supply. Its production is expected to increase approximately 3.1% each year in the next 25 years maintaining its share in t ...
Energy demand and renewable potentials need to be synchronized in time and space. Energy has to be provided at the right place at the time of demand and in the quantity needed. This means, that a spatial model of the region has to be elaborated that is bas ...

In practice, the quest for the optimal operation of energy systems is complicated by the presence of operating constraints, which includes the need to produce the power required by the user, and by the need to account for uncertainty. The latter concept in ...
Presenting the best papers of the 3rd EPFL-UNESCO Chair Conference on Technologies for Development, this publication offers a valuable collection of innovative case studies exploring access to energy and renewable energy technologies in the Global South. I ...
In this work, a comparative exergy and environmental analysis of the vehicle fuel end use is presented. This analysis comprises petroleum and natural gas derivatives (including hydrogen), biofuels (ethanol and biodiesel), and their mixtures, besides of the ...
The average unit exergy cost and CO2 emissions of the electricity generated in Brazil are evaluated using the national electricity mix and considering the representative profiles of the electricity generation routes. The Brazilian installed capacity is com ...
In practice, the quest for the optimal operation of energy systems is complicated by the simultaneous presence of operating constraints, among which the need for producing the power required by the user, and of uncertainty. The latter concept incorporates ...
