Europe's First Non-Fossil Based Natural Gas Production Achieved in Extremadura Using Green Hydrogen and CO2
Europe has taken a major leap forward in the renewable energy sector with the realisation of its first non-fossil based natural gas in Extremadura. The project involves synthesising renewable natural gas (RNG) by combining green hydrogen with biogenic carbon dioxide, employing innovative Power to Gas technology. This achievement positions Extremadura as an influential hub in Europe's energy transition, demonstrating the commercial viability of renewable gases.
At the heart of this development is the Miajadas plant, operated by Turn2X, which has pioneered the real-time injection of green gas into the existing natural gas distribution network. The facility utilises electrolysis powered entirely by renewable energy to produce hydrogen, which is then combined with biogenic CO2 from local bioethanol operations. The reaction, known as Sabatier, converts the gases into high-purity synthetic methane, available for industrial use and transportation.
This renewable natural gas operates seamlessly within the existing pipeline infrastructure, allowing various industries, including steel, ceramics, and maritime sectors, to decarbonise where electrification is more challenging. The project, managed by Turn2X Asset Co II Extremadura SL, has a planned capacity of 9 megawatts of electrolysis, with the potential to produce around 6390 tonnes of renewable hydrogen over its first decade.
The initiative is supported by significant European funding, including a fixed subsidy of 0.62 euros per kilogram of certified hydrogen produced. Once operational, the plant can be brought into commercial use within five years under agreed timelines. The project also benefits from an innovative renewable energy Power Purchase Agreement with Axpo Iberia, ensuring electricity supply from renewable sources to maintain the sustainability of hydrogen production.
Extremaduras favourable solar conditions and strategic location along the planned European hydrogen infrastructure corridor have been key factors in the projects choice of location. The region is poised to expand its renewable energy ecosystem further, with plans for additional facilities and increased local investment, bolstered by regional human capital and prior successful energy investments.
This project underscores a practical shift in Europes energy landscape, transforming green hydrogen from a promise into a tangible, economically viable industrial solution. The realisation of renewable natural gas production is set to attract further investments, create high-quality jobs, and foster energy independence across the continent. Spain, particularly Extremadura, is emerging as a genuine pioneer and operational starting point in Europes journey towards sustainable energy security.
