Aviation

The sector with the least technical optionality and therefore the strongest policy-driven demand for the most expensive molecules.

How molecular energy affects aviation

Aviation has effectively no alternative to liquid hydrocarbon fuel for long-haul flight within foreseeable technology, and its fleet and infrastructure will be in service for decades. That makes drop-in sustainable aviation fuel the only viable route, and it makes aviation the sector most likely to pay the premium that e-fuels require. Mandates in several jurisdictions are creating demand that price alone would not, which is both the opportunity and the principal risk.

Relevant molecules

What competes

  • Bio-SAF from waste oils and fats — cheaper today, sharply feedstock-limited
  • e-SAF from hydrogen and CO2 — scalable in principle, expensive in practice
  • Alcohol-to-jet routes including ethanol and methanol pathways
  • Hydrogen aircraft and efficiency improvements, relevant mainly to short-haul and the longer term

Where the commercial opportunities are

e-SAF production where very low-cost, high-availability renewable power exists

Long-term SAF offtake with airlines and freight operators under mandate pressure

Book-and-claim structures that decouple physical supply from the claim

CO2 supply into SAF projects, particularly from biogenic sources

Questions

Why is e-SAF so expensive?

Because it accumulates the cost and the energy losses of every upstream step — electrolysis, carbon capture, synthesis and refining. The result is a fuel competing against a product refined from crude oil at enormous scale. Its case rests on having no alternative and on policy mandates, not on cost parity.

Is bio-SAF or e-SAF the better opportunity?

Bio-SAF is cheaper and available now but constrained by sustainable feedstock, so it cannot meet mandated volumes alone. e-SAF is expensive and scalable. Most credible market views require both, with e-SAF's share growing as mandates tighten beyond what feedstock can supply.
