The Role of E-fuels in Decarbonising Transport
Executive Summary
Rapid deployment of low-emission fuels is crucial for accelerating the decarbonization of the transport sector. While significant electrification opportunities exist for road transport, aviation and marine sectors remain more reliant on fuel-based solutions. E-fuels, obtained from electrolytic hydrogen, could become a viable pathway, scaling up quickly by 2030 with the expansion of cheaper renewable electricity and anticipated cost reductions of electrolysers. These fuels can complement biofuels production, particularly in biogenic CO2 utilization.
