Global biofuels: renewable diesel and SAF growth depends on feedstock security, not refinery capacity

Global biofuel demand is rising, but the real bottleneck is feedstock supply, not refinery capacity. This assessment looks at how ENI Enilive, Neste, and other producers are expanding renewable diesel and sustainable aviation fuel output while competing for used cooking oil, animal fats, and other waste lipids. It also compares policy frameworks in the EU, UK, and US, and explains why mandates alone do not guarantee profitable or low-carbon production. The article digs into the gap between announced capacity and actual throughput, using Enilive's 1.65 million tonne refinery target as an example. It also covers the role of pretreatment, hydrocracking, and hydrogen use in improving yields. For anyone tracking renewable diesel, SAF, or biofuel policy, this is a useful update on where the industry actually stands heading into 2030.

The piece makes a fair point: capacity announcements are not production. Enilive's 1.65 Mt capacity vs 1.157 Mt throughput is a useful reminder that nameplate numbers get quoted a lot. Feedstock is the real bottleneck, especially used cooking oil and tallow. Worth reading for the feedstock competition angle.

I like that the article separates policy demand from actual decarbonization. A SAF mandate does not guarantee lower emissions if the waste oil was already used elsewhere. The UK call for evidence on crop-derived SAF is a sign that regulators are starting to ask who else wanted those molecules.

The refinery conversion angle is interesting, but the article also touches on hydrogen use and hydrocracking for SAF. Higher jet yield usually means more hydrogen, which can blow up carbon intensity if the hydrogen is fossil. Would have liked more on how plants plan to source low-carbon H2.

The EU Union Database is only as good as enforcement. If upstream verification is weak, waste classification games will continue. The article is right that policy should reward auditable output and lifecycle performance, not installed capacity. That is a hard shift for incentive design.

The IEA numbers show SAF going from 1 to 9 billion litres by 2030, but that is policy-dependent. The article is careful not to treat forecasts as guarantees. Good context for anyone tracking renewable diesel and aviation fuel mandates.
