We turn CO₂ emissions into sustainable jet fuel on a mission.

• Product — eSAF, a drop-in sustainable aviation fuel compatible with existing aircraft infrastructure [1].
• Delivery — production via a pilot unit in Finland, with scaling planned through partnerships for refining crude eSAF into final aviation fuel [1].
• Unit of value — carbon recoding efficiency and cost parity with conventional SAF, driven by new electrolyzer stack designs [1].
• Margin driver — cost reductions in core components and compatibility with existing energy infrastructure to accelerate mass production [1].

• Conventional SAF producers — companies using biomass or waste feedstocks, lacking Liquid Sun's carbon recoding scalability [1].
• Other eSAF developers — firms focused on power-to-liquid technologies, often lacking pilot validation and EU regulatory alignment [1].
• Differentiators — Liquid Sun's proprietary electrolyzer stack design, pilot unit validation in Finland, and focus on cost parity with conventional SAF [1].
• Threats — slower-than-expected regulatory adoption or breakthroughs in alternative decarbonization technologies [1].

• Regulatory pressure — airlines and fuel suppliers face EU mandates requiring eSAF adoption starting 2030 [1].
• High SAF costs — current sustainable aviation fuels lack price parity with conventional fuels, limiting adoption [1].
• Infrastructure limitations — need for drop-in fuels compatible with existing aircraft and energy infrastructure [1].
• Energy security concerns — Europe seeks locally produced synthetic fuels to reduce dependence on fossil fuel imports [1].

Liquid Sun's pilot unit validation and electrolyzer stack innovations position it as a key player in Europe's eSAF transition, leveraging regulatory mandates and energy security goals. The main risk is scaling production cost-effectively to achieve price parity with conventional SAF. The opportunity lies in securing long-term partnerships with airlines and refining firms to lock in demand. The next signal to watch is the pace of EU eSAF mandate enforcement and Liquid Sun's progress in refining crude eSAF with partners.

Liquid Sun should prioritize securing long-term offtake agreements with airlines to de-risk scaling and demonstrate market demand. Expanding partnerships with European energy infrastructure firms could accelerate mass production and reduce costs. Investing in public communication around EU RED compliance and certification processes would strengthen credibility with regulators and buyers. Exploring additional feedstock sources beyond captured CO₂ could enhance scalability and resilience against supply chain disruptions.
