Examining the potential of marine renewable energy: A net energy perspective

Share

Summary

It is often claimed that marine renewable energy alone could meet the electricity demand of current and future human societies. However, such claims are based on highly uncertain estimations of the global potentials of marine renewable energy sources (including tidal, ocean currents, wave, offshore wind and salinity and thermal gradients), and do not take into account the embedded energy of current technologies. To better understand the effective potential of marine energy, in this work we conducted a literature review of its gross, technical, economic and sustainable potentials, as well as the energy return on investment (EROI), and estimated the net energy potential. The results of this work suggest that the contribution of marine renewable energy to the future energy mix may be important, but not be as significant as generally thought.

Breu biografia

Enginyer Geòleg per UB-UPC (2009) i doctor Enginyer Ambiental per la UPC (2014). L’eix conductor de la seva recerca ha estat la programació científica i la modelització, inicialment del tractament d’aigües residuals i la digestió anaeròbia, i des del 2018 en models d’Avaluació Integrada per la transició energètica. Ha desenvolupat la seva recerca entre Catalunya i França, i tan en l’àmbit públic com en el privat. Entre 2018 i 2019 va treballar a l’ICM, en el marc del projecte Europeu MEDEAS, liderat pel Jordi Solé. Actualment treballa al CREAF, i participa en el projecte H2020 LOCOMOTION, el projecte Horizon Europe ToBe i el projecte pymedeas_cat, que és un encàrrec de l’Oficina Catalana de Canvi Climàtic.
