- Energy in Transports, coordinated by Prof. Tiago Farias
The Energy in Transports research area aims at developing activities in the fields of sustainable mobility, alternative fuel vehicles, vehicle dynamics and environmental performance and alternative and sustainable energies within the transport sector. In more detail, the research areas currently covered are: quantification of impacts of different vehicle technologies and alternative energy pathways, in particular electric solutions for urban mobility; real time monitoring of dynamic, energy and emissions characteristics of vehicles; and the evaluation of sustainable mobility solutions.

- Renewable Energy Technologies, coordinated by Prof. Luis Gato
The Renewable Energy Technologies group has been active for over thirty years, specializing in ocean wave energy conversion and turbines for small hydroelectric plants.
Most of the work focused on wave energy conversion, in which the group achieved high international recognition. A high landmark was the overall coordination of the four European projects that funded the basic studies, design, construction and monitoring of the European wave energy pilot plant at the island of Pico, Azores. This plant was the first wave energy plant worldwide designed to permanently supply electrical energy to a grid and was operational until 2018. The activity and expertise of the group covers most areas in wave energy technology. Strong points are hydrodynamics, numerical modelling, model testing, power take-off equipment, especially air turbines, plant control and moorings. In the last few years, the activity focused on offshore wave energy converters of oscillating water column type and on the development of new types of air turbines.
Beyond wave energy, the group has contributed to the numerical and experimental advancement of small hydraulic turbines, particularly cross-flow and Kaplan-bulb types.
