Decarbonizing Transport and Energy: SAF, Maritime Electrification, and Nuclear SMRs

Industry insights from Innovation Zero 2026 highlight the push toward sustainable aviation fuels (SAF) and e-fuels. Companies like Lighthouse Fuels are developing second-generation SAF projects using biomass and carbon capture to achieve carbon-negative flight emissions, responding to strict UK mandates. Beyond aviation, the focus is shifting toward maritime electrification and the growth of nuclear energy. While small vessels are transitioning to batteries, larger ships require complex port infrastructure. Meanwhile, the rise of Small Modular Reactors (SMRs) provides a scalable path for grid decarbonization in the UK and France.

The part about ships giving energy back to the grid is interesting, but it depends entirely on port interconnection capacity. Most ports are already struggling with power limits. Do we have any data on the actual megawatt requirements for these shore-to-ship systems?

That is why the lack of regulation mentioned in the text is a problem. Without a clear mandate or subsidy for port infrastructure, shipping companies will just wait. The aviation sector is ahead because the SAF mandate creates a guaranteed market.

Lighthouse Fuels claiming carbon negative SAF is a big deal if they actually scale the carbon storage part. Most biofuels just claim to be lower carbon, but true negative emissions require a very tight grip on the whole supply chain.

SMRs sound great in a report, but the civil engineering and labor costs for nuclear are always the bottleneck. I want to see the actual construction timelines for these modular designs before I believe they can move the needle quickly.
