Teaching language



The curricular unit Renewable Energies I aims to prepare students to select, acquire, operate and develop technologies and solutions in the field of Renewable Energies.
The subjects studied in this UC are: a) energy and solar radiation; b) solar thermal collectors; c) solar power concentrators; d) solar thermolysis; e) electrochemistry; f) fuel cells; g) electrolysis; h) electroreduction of CO2; i) batteries; j) photoelectrochemistry; k) photovoltaic cells; and m) photoelectrochemical cells.

Learning outcomes and competences

Students who successfully complete the UC of ERI should know the physical and / or chemical principles related to the technologies taught as well as the potential benefits of these technologies. In particular, they should know and apply: a) the astronomical equations relating to sun, its relative position and radiation on a surface b) working principles of a solar thermal collector, technologies and applications; c) working principles of a concentrator solar power unit, technologies and applications; d) electrochemical equilibrium and kinetic equations (equations Nernst and Butler-Volmer and Tafel) e) working principles of a PEMFC, simple phenomenological modeling, electrochemical impedance, electrical analogues, technology and applications; f) working principles of an electrolyzer, technologies and applications; g) electroreduction of CO2; h) working principles of a battery, technologies and applications; i) working principles of a photovoltaic cell, simple phenomenological model, technologies and applications; j) working principles of a photoelectrochemical cell, technologies and applications. Students should also be able to value the social relevance of the sustainable technologies.

It is expected that students develop the following skills: a) use of physical and / or chemical principles taught for selecting, characterizing, operating, optimizing and designing solutions involving technologies lectured b) teamwork c) oral and written communication and public discussion of results.

Eligibility for exams

Students have to do the assignments to be admitted to exams.
Students who attended to the course in previous years can other do the assignments and exam or just the final exam.

Calculation formula of final grade

FM- 0.25 x CA + 0.75 x FE

CA - Continuous Assessment

This component covers a written work and its oral presentation followed by discussion .

FE - Final Exam

Students have to reach a minimum grade of 8 out of 20 in the final exam.

Examinations or Special Assignments

Single exam

Special assessment (TE, DA, ...)

Single exam, without weighting the continuous assessment.

Classification improvement

Single exam, without weighting the continuous assessment.
