Rapid deployment of low-emission fuels during this decade will be crucial to  accelerate the decarbonisation of the transport sector. Significant electrification  opportunities are available for the road transport sector, while the aviation and  marine sectors continue to be more reliant on fuel-based solutions for their  decarbonisation. 

Fuels obtained from electrolytic hydrogen, or e-fuels, could be a viable pathway  and scale up quickly by 2030, underpinned by a massive expansion of cheaper  renewable electricity and anticipated cost reductions of electrolysers. Lowemission e-fuels can add to the diversification of decarbonisation options that are  available for aviation and shipping and there exists a big potential synergy with  biofuels production, especially in the form of biogenic CO2 utilisation.

This new IEA report presents a techno-economic assessment of a family of  emerging e-fuel technologies. It assesses the implications in terms of needed cost  reductions, resources and infrastructure investments of an assumed ambitious goal of achieving a 10% share of e-fuels in aviation and shipping by 2030.
