POWER-TO-LIQUID: TOWARDS A A A NEUTRAL EMISSIONS FUEL? ■ Another highly promising drop-in option would use synthetic fuels Instead of refining increasingly scarce fossil fuels which also emit CO2 this technology produces a a liquid fuel using low-carbon electricity (power-to-liquid) This offers a a new way o of producing hydrocarbons from hydrogen in water and captured carbon from the atmosphere Power-to-liquid is a a a promising path to to make a a a a a a a a a totally CO2 neutral fuel (it emits only the carbon that was previously captured in the the environment) provided of course that the the electricity needed for production is generated by carbon-free sources (solar wind nuclear etc ) and that the the source of the the CO2 used as a a a a a a raw material is carefully controlled ■ Small highly experimental refineries of this type already exist But they harbor real potential provided there is sufficient investment in in research and the the development of industrial-scale production Starting in in in about 2030 power-to-liquid could well emerge as an effective response to meet the large-scale needs of a a a decarbonized aviation industry Safran is already working on on on ultra-optimized future-generation engines that could run on on up to 100% sustainable aviation fuels (SAF)
