The small amounts of SAF purchased by airlines will not compensate for the sector’s emissions growth projected in the coming decades. In 2023, SAF accounted for less than 0.2% of the total jet fuel consumed globally. This share should grow over the next decade as green fuels laws in the EU and UK kick in. But until a European industrial strategy for e-kerosene is developed, the supply of SAF will not be adequate for airlines to meet their net-zero goals.

As long as there are fertilizers made of ammonia, and as long as there is ammonia produced from fossil gas, e-kerosene is the wrong solution. Fossil free hydrogen, when used as feedstock for ammonia production, displaces almost double the emissions that of e-kerosene. So all demands for e-kerosene work the wrong way. The scarce amount of H2 should be directed where the impact is best. Long haul air travel is the hardest to decarbonise. Biofuels remain in the toolbox. No biofuels should be used in road traffic, because all road traffic is easy to decarbonise with batteries. EU should rewire the SAF for 100% biofuels for as long as there is fossil ammonia produced. @ https://www.linkedin.com/posts/karsten-capion-81591a42_how-do-we-best-use-green-hydrogen-and-captured-activity-7271833288128745472-q825?utm_source=share&utm_medium=member_ios

BIO fuels SAF will power the long range aircraft’s of the future. E-fuel will never be a solution, because it’s too inefficient and too expensive. Short to medium range will switch to batteries, which is not at all mentioned in the articles. https://illuminem.com/illuminemvoices/aviation-is-a-major-climate-problem-but-electrification-and-biofuels-are-solutions https://cleantechnica.com/2023/05/23/the-pathways-to-biofuels-a-survey-of-why-we-should-stop-fretting/

That's right it will not currently but as agreements between B2B travellers and airlines increase through voluntary commitments this will build the market. We wrote some thought on collaboration and the blocker to collaboration: https://www.linkedin.com/pulse/radical-collaboration-washing-sarah-wilkin-pev4e/?trackingId=2h94FuS4QAKAsf2S1sg6Zg%3D%3D

SAF is a waste of time Carbon Dioxide Removal using DAC is the only way forward https://www.linkedin.com/pulse/can-air-travel-made-sustainable-leon-di-marco/

T&E Lufthansa calculated that to fuel their existing fleet with eSAF would take half of German electricity generation. To my knowledge, there is no plan in place to create that much additional renewable electricity in Germany, let alone use it solely to make eSAF. We need to focus more on other feedstocks for SAF.

SAF is just greenwashing at the start of it all. There is nothing sustainable for SAF. https://www.iba.aero/resources/articles/sustainable-aviation-fuel-how-sustainable-is-it-really/ "While the research suggests that some of the impacts associated with SAF production may be less consequential than the burning of conventional jet fuel, the environmental issues are being shifted elsewhere down the supply chain, commonly referred to as burden-shifting. Data on the life cycle GHG emissions of feedstocks for SAF is extremely limited, suggesting this is a subject area that needs further research." The one solution #stopburningstuff instead of pretent.
