Energy Technologies for Agro-Industry
The goal of this course is to provide students with knowledge and tools that allow them understand, evaluate and intervene in the selection of energy technologies in the agro-industry sector.
In the end of the course, students should have acquired knowledge, skills and competences that allow:
- Understand power and energy concepts, in a perspective of electric and thermal generation.
- Be able to analyze the energy context to which they belong and the corresponding legislative framework.
- Get familiar with electric and thermal technologies for energy production, storage and recovery, and evaluate application examples in the agro-industrial sector.
- Be able to select previous technologies for specific applications, based on production estimates and technical and economical viability studies.

The distinct concepts, techniques and theories are explained by the lecturer with the support of slides and demonstrators available in FCT/UNL, with which students execute laboratory or demonstration activities. These are prepared for the classes by the lecturer, and the latter allow verifying or analysing distinct behaviours and operation regimes.
Students assess their skills through semiautonomous resolution of sets of problems, available in the slides, as well as small projects related with the subjects.
The continuous assessment is based on the grades of three tests, T1 to T2, where the final grade is obtained by the arithmetic mean grade of those tests (rounded to units).
T3 test has a minimum grade of 8/20.
If students fail in the continuous assessment, they should be approved on the final exam.
