STX Group and TURN2X bring RFNBO-compliant e-methane to market

AMSTERDAM (October 12, 2026) – STX Group, a leading environmental commodity trader, today announces its first offtake of RFNBO (Renewable Fuel of Non-Biological Origin)-compliant e-Methane, produced by TURN2X at its first commercial plant in Spain. The agreement provides STX Group with access to TURN2X’s RFNBO-compliant e-Methane and allows the firm to expand its renewable gas portfolio. 

 The offtake brings together TURN2X’s load flexible methanation technology and project development skills with STX Group’s deep environmental commodities expertise, regulatory knowledge and downstream market access. By integrating an emerging renewable fuel into its existing product suite, STX Group can provide bankability and liquidity in a rapidly growing sector and a route to compliance for obligated parties. 

 E-Methane is a synthetic fuel produced from renewable hydrogen from electrolysis and biogenic CO2. Like biomethane, the molecule is interchangeable with natural gas, giving it access to the European gas grid and a wide range of applications across the EU and beyond. Synthetic fuels are a key part of the energy transition, driving investment in electrolysis and carbon capture, without the immediate need to build hydrogen infrastructure. In addition, TURN2X’s load-flexible methanation plants can absorb surplus renewable electricity from the grid, significantly reducing system costs. Key end-users for e-Methane are in the transportation sector, such as shipping and long-haul trucking, energy intensive industries and dispatchable power for AI data centers and other gas peakers.  

 Demand for RFNBOs is quickly increasing with more than ten countries implementing mandatory blending quotas for e-Methane and other RFNBOs as part of the RED III. For STX Group, the TURN2X offtake is a first step in building a broader RFNBO offering. 

 “This marks an important first step for STX Group in the RFNBO market,” said Diederik Francoys, Global Head of Renewable Gas and Managing Partner at STX Group. “Certified RFNBO supply is still scarce, which makes partnering with pioneering producers like TURN2X essential. Combined with our regulatory expertise and buyer network, we can bring these volumes to the obligated parties. We are excited to be an early mover in a market that we believe will have an increasingly important role in the European and the global energy mix.” 

 “We are proud to partner with STX Group and their extensive trading expertise to bring certified e-Methane from our first commercial plant into the key markets across Europe,” said Benedikt Stolz, Managing Director TURN2X. “With our load flexible methanation technology we can produce e-Methane at competitive cost and we look forward to scaling up supply to over 1 TWh in the coming years.” 

The first delivery of fully RFNBO certified e-Methane took place early in October 2026. The companies are also in active discussions to work together on future commercial-scale e-Methane projects.
