Biofuels for the transition to a decarbonized future

Near-zero emissions options for energy generation at local and medium scale are represented by renewables.
While these technologies continue to be developed, additional technical breakthroughs will be needed to achieve cost-effective deployment at the scale needed to transform the energy system.
Biomass combustion, in collaboration with DESTEC -Department of Energy, Systems, Territory and Construction – (Barontini et Al. 2018; Capusciutti et Al., 2018), and biomass gasification (Biagini et Al. 1014, 1015, 2016; Simone et Al. 2012, 2013a, 2013b) have been the main topics of research of DICI in the last decade, including biofuel production such as biomethane, biodiesel and torrefied biomass (Bacci di Capaci et Al. 2019, Tasca et Al., 2019; Li et Al., 2013).
The main objective, among others, was to demonstrate the feasibility and availability of technologies for local, small scale, distributed generation (Galletti et Al., 2016; Patronelli et Al. 2018).
Biomass combustion at the Cornia 2 hybrid geothermal/biomass power plant of Enel Green Power – an innovative technology integrating renewable and geothermal energy – has also been investigated (Galletti et Al. 2017).
