While most of Europe works toward RED III compliance, industrial offtakers are already demanding certified molecules as regulatory deadlines near. German trio – global technology major Siemens AG, regulatory technology company Atmen Solutions GmbH (Atmen), and power-to-gas project developer TURN2X GmbH – have developed the first end-to-end model for RED III-ready renewable gas production, from automated plant operations to certified product delivery.
Recently, Germany took a significant step toward closing remaining gaps in renewable fuel regulation.
The Bundestag held the first reading of the Second Law on the Development of the Greenhouse Gas Reduction Quota, which will transpose RED III into national law and, for the first time, introduce explicit quotas for green hydrogen and electro-fuels (e-fuels) in the transport sector.
Commercially viable
Using proprietary technology, TURN2X produces climate-neutral electro-methane (e-methane) by combining green hydrogen with biogenic carbon dioxide (bioCO2), a renewable fuel of non-biological origin (RFNBO).
The company plans to scale this model across Europe, aiming to cover 10 percent of Germany’s gas demand by 2031.
According to TURN2X, its Miajadas plant in Spain demonstrates the commercial viability of this pathway, with 100 percent of its renewable gas output sold under long-term off-take agreements.
Shared objective
The three companies share a single goal: scaling green energy production with intelligence, trust, and speed.
Siemens provides the industrial backbone for this model, including advanced automation systems, digital twin technology for remote plant operation, and standardised, secure deployment of future facilities.
Siemens adopts an ecosystem approach, collaborating with leading partners such as Atmen rather than developing every component in-house. “
This is exactly how we at Siemens want to go forward in renewable energies. We want to partner with the best solutions so our customers get innovation, technology, and speed of implementation, said Philipp Glaser, Siemens Digital Industries.
Atmen provides the certification data layer. At Miajadas, this enabled the site to reach full RFNBO certification, making automated compliance part of day-to-day operations.
Certification isn’t a nice-to-have; it’s market access and business case realization. Our platform turns operational data into verifiable, auditable proof that keeps production continuously certification-ready so that renewable fuel producers can scale with confidence, said Flore de Durfort, CEO of Atmen.
For TURN2X, combining Siemens’ industrial technology with Atmen’s compliance layer creates a blueprint for rapid, reliable expansion.
Scaling across Europe brings two challenges: maintaining operational excellence and meeting increasingly complex certification requirements for renewable fuels. The Miajadas plant shows that when intelligent operations and built-in compliance come together, e-methane can scale with the reliability our customers expect, said Dr Dominik Schollenberger, CTO of TURN2X.
