Siemens and CAPHENIA Partner to Scale Sustainable Aviation Fuel Production
Aviation News Editor & Industry Analyst delivering clear coverage for a worldwide audience.
Siemens and CAPHENIA have partnered to accelerate Sustainable Aviation Fuel (SAF) production using advanced plasma technology to meet rising global demand.
Key Takeaways
- •Partners to scale SAF production using an advanced plasma-based process.
- •Utilizes Siemens' automation and digital twin technology to industrialize plants.
- •Targets over 86% energy efficiency in converting bio-methane to synthesis gas.
- •Aims to meet growing SAF demand driven by net-zero goals and regulations.
Industrial technology group Siemens has formed a strategic partnership with cleantech company CAPHENIA to accelerate the industrial-scale production of Sustainable Aviation Fuel (SAF). The collaboration aims to combine CAPHENIA's innovative plasma-based conversion technology with Siemens' extensive automation and digitalization portfolio to create standardized, modular production facilities that can be rapidly deployed worldwide.
This partnership addresses a critical bottleneck in the aviation industry's effort to decarbonize: the urgent need to increase SAF manufacturing capacity. While demand for renewable aviation fuel is growing exponentially due to regulatory mandates and airline commitments, current production levels fall significantly short of what is required to meet long-term goals. According to the International Air Transport Association (IATA), SAF could contribute to around 65% of the emissions reduction needed for aviation to achieve its net-zero target by 2050. However, this requires a massive ramp-up from the current supply.
The Technology: Power-and-Biogas-to-Liquid
At the core of the collaboration is CAPHENIA’s patented Power-and-Biogas-to-Liquid (PBtL) process. This technology utilizes a proprietary Plasma Boudouard Reactor (PBR), a 3-in-1 zone reactor that converts bio-methane and other renewable resources into synthesis gas, the primary building block for synthetic fuels. The plasma process operates at temperatures of around 1,500 degrees Celsius to split the bio-methane molecules.
A key advantage of the CAPHENIA process is its high efficiency. According to a Siemens press release, the system achieves an energy efficiency of more than 86% through advanced heat recuperation, which captures and reuses waste heat. This makes the production of synthesis gas more cost-effective and energy-efficient, which are crucial factors for the economic viability of SAF on a large scale.
Siemens' Role: Scaling Through Digitalization
Siemens will leverage its Siemens Xcelerator portfolio of software and hardware to industrialize the CAPHENIA technology. This involves creating a complete "digital twin" of the production plants, allowing for simulation, optimization, and virtual commissioning before any physical construction begins. The implementation of Siemens' process control systems, such as SIMATIC PCS neo, will ensure fully automated and standardized operations.
"Decarbonizing aviation cannot be achieved without synthetic fuels," said Christian Gückel, Head of Vertical Chemicals at Siemens Digital Industries. "Demand for SAF is growing exponentially, yet production capacity urgently needs to be ramped up. This is exactly where Siemens comes in: with our digitalization and automation solutions, we are making CAPHENIA's technology industrially scalable and thus accelerating its global market ramp-up."
Mark Misselhorn, founder and CEO of CAPHENIA, echoed this sentiment. "This partnership shows how technology leaders are working together to drive forward the energy transition. Siemens brings the portfolio and expertise to standardize and digitalize our plants... Together, we are not only laying the foundation for the international ramp-up of our PBR technology – we want to lead it," Misselhorn stated.
Market Context and Regulatory Drivers
The partnership comes as the global SAF market is poised for significant expansion. An ASDReports market study estimated the market at approximately US$3.30 billion in 2026 and forecast it to grow at a compound annual rate of about 28.8% through 2036. The global aviation industry will need an estimated 500 million tons of SAF annually by 2050 to meet its climate goals.
This growth is heavily influenced by a strengthening regulatory environment. The European Union's ReFuelEU Aviation initiative mandates a progressive increase in SAF blending for flights departing from EU airports, starting at 2% in 2025 and rising to 70% by 2050. Similarly, the International Civil Aviation Organization (ICAO) has established a global framework aiming for a 5% reduction in CO2 emissions by 2030 through cleaner energies. SAF is also a key compliance tool for the ICAO's Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). In the United States, the Sustainable Aviation Fuel Grand Challenge has set a goal to produce 3 billion gallons of SAF in 2030.
Why This Matters
This collaboration between Siemens and CAPHENIA represents a critical step in translating promising SAF technology from the laboratory to global industrial scale. By focusing on digitalization and modular plant design, the partnership directly addresses the core challenges of cost, efficiency, and speed that have historically constrained SAF production. The success of this model could provide a replicable blueprint for rapidly expanding the global supply of renewable fuels, a necessary component for the aviation sector to achieve its ambitious decarbonization targets.
