Siemens, Atmen and TURN2X Build the Blueprint for Certified Renewable Gas Production

Read Current News story
  • Germany advanced RED III transposition last week, introducing explicit quotas for RFNBO (Renewable Fuels of Non-Biological Origin) for the first time
  • Siemens, Atmen, and TURN2X have built the first end-to-end model for RED III-ready renewable gas production at TURN2X's commercial e-methane plant in Miajadas, Spain
  • The Miajadas plant is fully operational, with 100 percent of its output sold under long-term offtake agreements, proof that green gas can be produced, certified, and delivered at a commercial scale today.

(Munich, March 10, 2026)  Last week, 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 e-fuels in the transport sector.

While most of Europe works toward RED III compliance, industrial offtakers are already demanding certified molecules as regulatory deadlines near. Siemens, Atmen, and TURN2X, all based in Munich, have developed the first end-to-end model for RED III-ready renewable gas production, from automated plant operations to certified product delivery. The plant of the future is already running at TURN2X's first commercial e-methane plant in Miajadas, Spain.

TURN2X produces climate-neutral e-methane by combining green hydrogen with biogenic CO₂. The company plans to scale this model across Europe, aiming to cover 10 percent of Germany’s gas demand by 2031. Miajadas demonstrates the commercial viability of this pathway, with 100 percent of its renewable gas output sold under long-term off-take agreements. 

Intelligent operation and an ecosystem approach by Siemens

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,” says Philipp Glaser, Siemens Digital Industries. “We want to partner with the best solutions so our customers get innovation, technology, and speed of implementation.”

The data infrastructure layer provided by Atmen

Atmen, a regulatory technology company, 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,” says Flore de Durfort, CEO of Atmen. “Our platform turns operational data into verifiable, auditable proof that keeps production continuously certification-ready so that renewable fuel producers can scale with confidence.”

The plant of the future, run by TURN2X

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,” says Dr.  Dominik Schollenberger, CTO of TURN2X. “The Miajadas plant shows that when intelligent operations and built-in compliance come together, e-methane can scale with the reliability our customers expect.”

The three companies share a single goal: scaling green energy production with intelligence, trust, and speed.

The plant of the future isn’t a vision. It’s running today in Miajadas.

Surfing the renewable energy waves with hydrogen 

Read Current News story

A new EU-funded project (SURFER) will support Europe’s energy transition by creating more resilient, decarbonised energy systems by advancing hydrogen electrolysers. Atmen joins the consortium to demonstrate how flexible electrolysers can support the penetration of renewables on the power grid.

Variable renewable energy sources (VRES), such as solar and wind, have become the cheapest energy sources available. However, the intermittent nature of VRES presents significant energy storage issues, and this has limited their deployment. At the same time, the production of green hydrogen from electrolysers is projected to represent a significant fraction of the energy usage in Europe’s future, decarbonised energy system. As electrolysers are very quick to start and stop, hydrogen can function as an energy buffer for renewable energy.

Flexible electrolysers for resilient grids

The Clean Hydrogen Joint Undertaking’s project SURFER (Supporting Uptake of Renewables with Flexible Electrolysers for Resilient energy systems) aims to facilitate the widespread deployment of variable renewable energy sources by demonstrating the use of flexible electrolysers as dynamic energy buffers. It also aims to stabilise multiple types of energy networks, focusing primarily on power grids, but also considering heat valorisation and isolated or weak grids.

SURFER brings research and industry partners like Atmen together to demonstrate, in real operating environments, how flexible electrolysers can support the stability of the power grid. This capability is essential for scaling both renewable power and renewable hydrogen in Europe.

The project brings together research institutions, industrial operators, grid actors, and digital compliance experts, including Atmen, to study and demonstrate how flexible electrolysers can be integrated into the power grid.

“SURFER addresses two of Europe’s key energy challenges at once: reducing the cost of green hydrogen and enabling higher adoption of renewables”, says project coordinator at SINTEF, Dr. Federico Zenith.

“High shares of renewable electricity introduce volatility and new constraints for power systems,” says Quentin Cangelosi, Co-founder of Atmen. “SURFER brings research and industry partners like Atmen together to demonstrate, in real operating environments, how flexible electrolysers can support the stability of the power grid. This capability is essential for scaling both renewable power and renewable hydrogen in Europe.”

SURFER's multi-disciplinary consortium consists of leading research institutions, hydrogen producers, grid operators, equipment manufacturers, and safety and certification experts. Together they will address the complexities of electrolyser dynamics and energy system integration, significantly advancing beyond the state-of-the-art. 

The main goal of the project is to enable electrolysis plants to make additional revenues from power grid stabilisation, also making the latter more resilient and decarbonised with increased VRES adoption and maximisation of their use. The project will improve energy security and drive down costs, thanks to additional sources of revenues and heat integration, thus supporting Europe's energy transition goals.

Multiple demonstration sites across Europe

Through multiple demonstrations across diverse European sites, including operational environments in France, Germany, and Norway, the project will improve the integration of these electrolyser technologies into the energy system. The partners will be the first in the world to provide grid services with electrolysis plants on a commercial basis.

The project will demonstrate the capabilities of Proton-Exchange Membrane ELectrolyser (PEMEL), Alkaline Electrolyser (AEL) and Solid Oxide ELectrolyser (SOEL) to rapidly modulate their operation to accommodate variations in renewable energy supply, grid demand and waste heat when available. The partners have made available their already existing, large-scale sites, rated up to 10 MW for PEMEL, 1.5 MW for AEL and 300 kW for SOEL.

The project is supported by the Clean Hydrogen Joint Undertaking and its members, co-funded by the European Union under Grant Agreement No. 101250344.
