e-Fuels

Fischer–Tropsch is a compelling choice when the objective is to maximize e-SAF production from available carbon and energy. In Topsoe’s G2L™ eFuels configuration, the FT route can deliver up to 12% more SAF for the same CO₂ input compared with MTJ, helping developers get more jet fuel from the same carbon source. This makes FT especially attractive in projects where access to compliant CO₂ is limited, strategic or cost-sensitive.

A key strength of the FT route is its ability to convert more of the incoming carbon into jet fuel. In the G2L™ eFuels setup, FT delivers 12% more SAF for the same CO₂ input than MTJ. This higher CO₂ utilization directly supports stronger plant economics and improved resource efficiency, which are critical advantages as carbon sourcing becomes a central factor in e-SAF project development.

Energy efficiency is one of the most important differentiators in e-SAF production because hydrogen generation and overall power consumption are major cost drivers. The FT route produces 7–15% more SAF for the same energy input, depending on electrolyzer type. For project developers, that means a greater share of renewable power is converted into revenue-generating jet fuel, strengthening both competitiveness and long-term project value.

Fischer–Tropsch combines strong yield performance with a simpler and more integrated process configuration. As a result, the levelized cost of SAF is 10–15% lower than MTJ. This cost advantage is driven by higher efficiency, fewer process steps and lower equipment count, all of which contribute to a more robust and bankable e-SAF business case.

For projects focused on aviation fuel, product selectivity matters. In the G2L™ eFuels configuration, FT is presented as producing 100% SAF, with possible naphtha co-product, while MTJ produces SAF together with a diesel blend component and possible naphtha. This makes FT especially attractive where the priority is to maximize SAF output and simplify the downstream product strategy.

Fischer–Tropsch is particularly well suited to centralized e-SAF projects where developers want full control of the value chain. The FT route is positioned for centralized plants and full control of the value chain, while MTJ depends on decentralized methanol production and its associated supply-chain exposure. For many projects, this gives FT an advantage in integration, operational control and overall project reliability.

Fischer–Tropsch stands out because it combines the key value drivers that matter most in project development: higher yield, higher energy efficiency, lower cost, scalability, and simpler operation. In practical terms, FT offers:

• Up to 12% more SAF for the same CO₂ input.
• Up to 15% more SAF for the same energy input.
• 10–15% lower levelized cost of SAF.

Together, these advantages help maximize output and revenue while reducing complexity and supporting execution confidence.

Fischer–Tropsch benefits from decades of industrial heritage and is positioned as a scalable and proven technology for centralized plants at any scale. This maturity matters in e-SAF projects, where technology credibility, execution confidence and long-term operability are essential for investors, lenders and developers.

Operational simplicity is a major differentiator. FT offers fewer process steps, which translates into lower complexity, reduced operational risk and easier project execution. In addition, FT can operate with hydrogen feed turndown to 20% capacity, supporting flexibility while maintaining a strong overall integrated plant concept.

Fischer–Tropsch is the preferred route when the priority is to maximize e-SAF production and build a strong, scalable, and economically competitive project.

It is particularly attractive when developers are targeting:

• Maximum e-SAF yield.
• High energy efficiency.
• Lower levelized cost.
• Centralized plant design.
• A mature, industrially proven technology base.
