Background: The ongoing reduction in the use of fossil fuels includes also the substitution of gasoline and diesel in the transportation sector. The future scenario forecasts direct electrification of vehicles fleet via electric batteries, but the extension of electric engines to heavy transportation sector seems still infeasible. In this perspective biofuels, such as synthetic natural gas (SNG), from biomass represent a valid alternative to gasoline and diesel in internal combustion engines of heavy transportation vehicles. Nevertheless, biomass is a scarce resource and therefore boosting the conversion of the carbon contained in the biomass through use of renewable electricity (producing the so-called “electrofuels”) represents a more sustainable solution.

Aim of the work: analyze a flexible system that can produce SNG combining biomass gasification using a TwoStage gasifier and electricity from renewable energy sources deeply integrated in the system through solid oxide cells (SOCs). The possibility to operate the system with different outputs (poly-generation system) enables to run the system no matter the electricity price, thus increasing the capacity factor.

Development of the project: the  work builds on top of a Ph.D. study oriented towards the production of methanol instead of SNG. The system will be developed through the thermodynamic modeling tool Dynamic Network Analysis (DNA). The analysis could comprehend a comparison with the system for methanol production, as well as a comparison with more traditional systems.

Requirements
