India could make sustainable aviation fuel 40 percent cheaper as a draft Farm Bill lands

India could produce sustainable aviation fuel about 40 percent cheaper than global benchmarks, an IECC report said, using low-cost solar power and crop residue as feedstock. Cost is the binding constraint for SAF, so a credible 40 percent cut is the kind of number that could actually move volume rather than just targets.

The cost ceiling

Airlines are struggling to persuade passengers to pay extra for SAF, which keeps demand soft and prices high. Cheaper production is the only durable fix. India pairing abundant solar with crop residue attacks both the energy cost and the feedstock cost at once, the two lines that make SAF expensive today. University of Illinois researchers added another route, converting food waste into jet fuel.

Policy and credits

Back home, the Senate Agriculture Committee released a draft Farm Bill, and biodiesel groups are reading it closely for blending and credit terms. That bill sets the economics for renewable diesel and biodiesel producers, since the federal credit structure feeds directly into blend margins. Any change to the producer credit moves real money for the plants already running.

The market case

The capital is betting on growth. One forecast put the green diesel market at $92.3 billion by 2032 on rising renewable demand. Renewable diesel and SAF keep drawing capital on the strength of mandates and long-run growth, even while current spreads stay tight.

What to watch

Watch the Farm Bill markup for biodiesel and renewable diesel credit language, since it sets producer margins. Track whether India's low-cost SAF model gets built or stays on paper. And watch airline willingness to pass SAF costs to passengers, because demand is the missing piece.
