Gas compatible with existing pipelines without drilling a single well
En un pueblo de Cáceres, una planta ha comenzado a inyectar metano sintético renovable en las mismas tuberías que transportan energía por Europa, sin perforar un solo pozo ni quemar un solo combustible fósil. La empresa alemana Turn2X ha demostrado en Miajadas que la tecnología Power to Gas puede operar a escala comercial real, convirtiendo electricidad renovable y dióxido de carbono capturado en un gas compatible con la infraestructura existente. Es un momento que desplaza el debate energético: ya no se trata de si esto es posible, sino de cuán rápido puede crecer.
- Europa lleva décadas buscando cómo descarbonizar industrias que no pueden simplemente enchufarse a la red eléctrica, y la planta de Miajadas ofrece la primera respuesta operativa a escala real.
- El metano sintético producido ya circula por la red de Gas Extremadura, lo que convierte a esta instalación en la primera de su tipo en alimentar infraestructura real en todo el continente.
- El proceso Sabatier une hidrógeno verde con CO₂ biogénico capturado de una planta cercana de bioetanol, produciendo un gas de alta pureza que no requiere modificar tuberías ni depósitos existentes.
- La Comisión Europea ha respaldado el proyecto a través del Banco Europeo del Hidrógeno, comprometiendo un subsidio fijo durante diez años como señal de que Bruselas apuesta por esta tecnología como puente estratégico.
- El hidrógeno verde sigue siendo caro y su producción consume enormes cantidades de electricidad, pero Miajadas ha cruzado el umbral que separa el laboratorio del mundo real.
En Miajadas, un pequeño municipio de Cáceres, una planta construida por la empresa alemana Turn2X ha comenzado a fabricar gas natural sin perforar pozos ni quemar combustibles fósiles. El producto es metano sintético, generado a partir de electricidad renovable e hidrógeno combinado con dióxido de carbono biogénico capturado de una instalación cercana de bioetanol. El proceso, conocido como Sabatier, transforma ambos elementos en un gas de alta pureza que ya se inyecta directamente en la red de distribución de Gas Extremadura, convirtiéndose en la primera instalación de este tipo en operar a escala comercial en Europa.
Lo que hace estratégica esta tecnología no es solo lo que produce, sino lo que evita: reconstruir desde cero la infraestructura energética del continente. Las tuberías, los depósitos y las redes de distribución existentes pueden transportar este nuevo combustible sin ninguna modificación. Eso importa especialmente para sectores industriales como el acero, la cerámica o el transporte marítimo, donde la electrificación directa sigue siendo técnicamente inviable. La Comisión Europea lo ha reconocido seleccionando el proyecto en la tercera subasta del Banco Europeo del Hidrógeno y comprometiendo un subsidio de 0,62 euros por kilogramo de hidrógeno certificado durante diez años.
Extremadura no fue elegida al azar. La región combina una irradiación solar excepcional con una posición clave en el futuro corredor europeo del hidrógeno, la red que conectará productores y consumidores de energía renovable a lo largo del continente. Esa geografía está atrayendo inversión y convirtiendo la región en un laboratorio industrial de primer orden para la nueva economía del hidrógeno.
Los desafíos persisten: el hidrógeno verde es costoso, el consumo eléctrico es enorme y escalar esta solución a nivel continental sigue siendo una tarea monumental. Pero Miajadas ha demostrado algo que no puede deshacerse: que el sistema funciona fuera del laboratorio, en condiciones reales, alimentando infraestructura real. Ese paso cambia la conversación sobre la independencia energética de Europa.
In a small town in Cáceres, something that looked impossible five years ago is now pumping gas into the same pipelines that carry energy across Europe. Turn2X, a German company, has built a plant in Miajadas that manufactures natural gas without drilling a single well or burning a fossil fuel. The gas it produces is synthetic methane, made from renewable electricity and carbon dioxide pulled from the air. More importantly, it works. The plant has already fed its product directly into Gas Extremadura's distribution network, making it the first facility of its kind to do so anywhere on the continent.
The technology is called Power to Gas, and it works like this: renewable electricity splits water molecules into hydrogen through electrolysis. That hydrogen then meets biogenic carbon dioxide—captured from a nearby bioethanol plant—and a chemical reaction called the Sabatier process transforms both into methane of high purity. The result is a gas that behaves almost identically to conventional natural gas. This compatibility matters enormously. Europe does not need to rebuild its entire energy infrastructure from scratch. The pipes, the storage facilities, the distribution networks that exist today can carry this new fuel without modification.
The European Commission took notice. It selected the Miajadas project for official backing through the third auction of the European Hydrogen Bank, a signal that Brussels sees this work as strategically important. The reasoning is straightforward: large sectors of European industry remain nearly impossible to electrify. Steel mills, ceramic factories, and cargo ships require sustained high heat and enormous continuous energy flows. Batteries do not solve that problem. Synthetic methane does. It is a bridge technology for industries that cannot simply switch to electricity, at least not yet.
The plant itself will operate with about nine megawatts of electrolysis capacity and is expected to produce roughly 6,390 tons of renewable hydrogen over its first decade. The European Union will pay a fixed subsidy of 0.62 euros per kilogram of certified hydrogen produced, a commitment that runs for ten years. Turn2X has signed a power supply agreement with Axpo Iberia, which will deliver electricity from renewable sources managed by Aquila Clean Energy. The entire system is designed to remain renewable from start to finish.
Extremadura was not chosen by accident. The region sits at the intersection of two critical advantages: abundant solar energy and a strategic position along the planned European hydrogen corridor, the infrastructure that will eventually transport renewable hydrogen between countries across the continent. This geography is already beginning to reshape the region. Extremadura is becoming something more than a production site. It is emerging as one of Europe's most important industrial laboratories for the new hydrogen economy. Investment is flowing in from energy companies, specialized engineering firms, and new industrial projects.
The obstacles remain substantial. Green hydrogen is expensive to produce. The electricity consumption is enormous. Scaling this technology from a single plant to industrial relevance across Europe is still one of the sector's greatest challenges. But the Miajadas facility has crossed a threshold that matters: it has moved synthetic methane from the realm of theory and laboratory simulation into the real world. It has proven the system works outside controlled conditions, feeding actual gas into actual infrastructure. That shift changes how Europe thinks about its energy independence and the tools available to achieve it.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that this gas can go directly into existing pipelines? Couldn't they just build new infrastructure designed for synthetic methane?
Because Europe does not have time or money to rebuild everything. The pipelines, storage tanks, and distribution networks already exist and work. Using them means you can deploy this technology at scale immediately, not in ten years after construction. That speed is the whole point.
The Sabatier process—is that new, or has it existed for a long time?
It's been known since the early 1900s. What's new is doing it at industrial scale with renewable electricity and captured carbon. The chemistry is old. The application is what changes everything.
You mentioned steel mills and ships. Why are those so hard to electrify?
They need sustained, intense heat. A steel furnace runs at temperatures that batteries cannot reach, and it runs continuously. You cannot stop it to recharge. Synthetic methane burns like natural gas, so it fits into existing industrial processes without redesigning the entire factory.
Is this plant profitable on its own, or does it only work because of subsidies?
Right now it depends on the EU subsidy—0.62 euros per kilogram of hydrogen. That is the bridge. The question is whether costs fall fast enough that the technology becomes competitive without subsidies. That is what the next five years will show.
Why is Extremadura becoming so important for hydrogen?
Solar energy is abundant there, and it sits on the planned hydrogen corridor that will connect European countries. It is geography plus infrastructure plus investment all aligning at once. That combination does not happen often.
What happens if this plant fails or the technology does not scale?
Then Europe has to find another way to decarbonize industries that cannot be electrified. Right now, there are not many alternatives. That is why the stakes feel high.
