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 a a “green” electrosynthesis process (power-to-liquid) This offers a a new way o of producing hydrocarbons from hydrogen in in water and captured carbon from the atmosphere Power-to- liquid is is a a a a a a 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 environment) provided of course that 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)
