Daniela Falcão, assistant researcher at CEFT/ALICE, performed several oral presentations entitled “Hydrogen as a new energy vector” in high schools of the northern region of Portugal. These presentations explain, in a simple way, the importance of hydrogen as an energy vector and how low emission energy processes are essential to mitigate the problem of climate change, acting close to the community. This series of lectures started with the HyGreen & LowEmissions project (NORTE-01-0145-FEDER-000077), which ended in 2023, but it is intended to continue.
