The energy transition group has a research agenda focused on the development of sustainable and systemic solutions to the energy transition. The foundations for the energy transition are generation of renewable and clean energy and its efficient and well managed used. We target both challenges, with focus on:

  1. Solar energy, from materials for energy to resource assessment and forecasting, distributed generation, system integration with electric vehicles and long term renewable energy scenarios;
  2. Energy in buildings, including theoretical  and experimental approaches to natural ventilation and building stock energy modelling, applied research and design projects as well as building energy audits;
  3. System energy and emission analysis including mass and energy flow balances of systems transportation and biorefinery systems

Group Leader: Guilherme Carrilho da Graça

Scientific Highlights 2019

Further consolidating the collaboration of science and technology research centers with the economic and social fabric, this year witnessed the launching of three National Science Foundation (FCT) funded Collaborative Laboratories with the participation of the Energy Transition group: the Smart Energy Lab ( with key stakeholders in the power sector, Biorefineries ( to advance the circular economy, and Smart Farm ( to tackle the challenges of global change for the agricultural sector.
This year was also marked by international collaborations on new research lines, such as a new DAAD funded collaboration on tunneling junctions for silicon-perovskite tandem solar cells, and the development of new materials for high power and high energy supercapacitors, with the University of Loughborough.

There are three main research highlights for this year. The first is an analysis of the impact of the elimination of coal plants for power generation in Portugal, showing how increasing photovoltaic capacity at solar power plants can speed up the closure of CO2-emitting thermal power plants. The second is an analysis of the impact of global warming on biomass-to-ethanol conversion. The third is the first experimental characterisation of the thermal behaviour of residential buildings as a thermal batteries for straightforward combination of building energy management and flexible residential loads.
