Green guels is a key technology for the transition towards fossil-free energy systems. The production of carbon neutral synthetic fuels is primarily driven by the need to decouple the energy sector from fossil fuels dependance which are the main source of environmental issues. Hydrogen (H2) produced from water electrolysis powered by renewable electricity an‎d direct carbon dioxide (CO2) captured from the flue gas generated by power plants, industry, transportation, an‎d biogas production from anaerobic digestion, are used to convert electricity into carbon-neutral synthetic fuels. These fuels function as effective energy carriers that can be stored, transported, an‎d used in other energy sectors (transport an‎d industry). In addition, the Power to Fuel (PtF) concept is an energy transformation that is capable of providing services for the balancing of the electricity grid thanks to its adaptable operation an‎d long-term storage capacities for renewable energy surplus. As a consequence, it helps to potentially decarbonize the energy sector by reducing the carbon footprint an‎d green house gas (GHG) emissions. This seminar gives an overview on recent advances of green fuel technologies for the e-production of three main hydrogen-based synthetic fuels that could substitute fossil fuels such as power-to-hydrogen (PtH2), power to-methanol (PtCH3OH) an‎d power-to-ammonia (PtNH3). The first objective is to thoroughly define in a clear manner the framework which includes the PtF technologies. Attention is given to green H2 production by water electrolysis, carbon capture & storage (CCS), CO2 hydrogenation. The second objective is to gather an‎d classify some existing projects which deal with this technology depending on the e-fuel produced (energy input, conversion process, efficiency, fuel produced, an‎d application). Furthermore, the challenges an‎d future prospects of achieving sustainable large-scale PtF applications are discussed.
