Ultra-low carbon intensity for second-generation sustainable aviation fuel through CCUS and blue hydrogen

A new analysis from Northpointe Energy CEO Paul Hubbard shows that second-generation sustainable aviation fuel (SAF) can reach ultra-low carbon intensity when paired with regional carbon capture and storage (CCUS) infrastructure and clean energy production. The key is replacing conventional natural gas burners with blue hydrogen to cut process emissions, and capturing biogenic CO2 to achieve deeply negative carbon intensity scores. This negative carbon profile matters because it reduces the volume of negative-CI SAF needed when blending with conventional fossil jet fuel. The analysis focuses on the UK and European markets, where CCUS networks and clean energy facilities are developing. For project developers, the takeaway is that SAF economics improve significantly when sited near these supporting infrastructure systems. The article is worth reading for anyone tracking how aviation decarbonization connects to broader CCUS deployment and hydrogen production. It gives a concrete look at the engineering choices that determine whether a SAF project delivers real emissions cuts or just incremental gains.

This is the kind of detail that gets skipped in the hype. Negative CI SAF only works if you have the CCUS and hydrogen infrastructure nearby. Not every site can do that.

Right. And blue hydrogen still needs natural gas feedstock and its own carbon capture. So you are stacking one CCS project on top of another. The system complexity adds up fast.

The negative CI angle is interesting for policy. If the CI score is low enough, it could count for more under blending mandates. That changes the math on project finance.

But only if the regulator actually recognizes biogenic CO2 capture as negative. Some frameworks still treat it as avoided emissions rather than removal. That distinction matters for the credit value.

The UK and Europe focus makes sense. They have the most developed CCUS cluster plans. But the article does not say how many SAF projects are actually co-located with those clusters today.

Not many. Most SAF projects are still in the feasibility stage. The real bottleneck is pipeline infrastructure for CO2 transport. Without that, the negative CI claim stays theoretical.
