Pulse Analysis

The UK’s recent SAF mandate, requiring 2% of jet fuel to be sustainable and scaling toward 100% by 2040, is reshaping the aviation fuel landscape. Companies like Lighthouse Fuels are leveraging second‑generation pathways—using agricultural residues and sugar‑cane bagasse—to produce carbon‑negative SAF, a differentiator that could attract airlines seeking to meet tightening emissions targets. Meanwhile, Hy Five’s e‑methanol and e‑SAF projects in Spain illustrate how green hydrogen is becoming a versatile feedstock for low‑carbon fuels, expanding the market beyond traditional bio‑derived routes.

Maritime decarbonisation presents a distinct set of challenges, chiefly the lack of uniform regulations and the sheer size diversity of vessels. Marine Zero’s approach—combining data analytics, feasibility studies, and charging‑infrastructure mapping—helps ship owners identify the most cost‑effective electrification pathways, whether through battery‑powered ferries or shore‑side power connections that can also feed excess energy back to the grid. This data‑centric model reduces investment risk and accelerates adoption, positioning electric propulsion as a viable alternative for short‑haul and regional vessels while larger ships explore hybrid or plug‑in solutions.

Nuclear small modular reactors (SMRs) are gaining traction as a steady, low‑carbon baseload source, especially in markets like the UK where nuclear already supplies a significant share of electricity. Assystem’s involvement across design, engineering, and commissioning phases signals confidence in the commercial viability of SMRs, supported by partnerships with EDF, Rolls‑Royce, and Great British Energy Nuclear. The firm’s end‑to‑end services address the skill gaps and regulatory hurdles that have historically slowed nuclear deployment, aligning with IDTechEx’s forecast of robust SMR growth through 2046. Together, these developments illustrate a converging ecosystem of biofuels, electrified transport, and advanced nuclear that could collectively drive deep decarbonisation across the energy‑intensive sectors.
