Miajadas Spain turns green hydrogen and captured CO2 into renewable gas for existing pipelines

A small town in Extremadura, Spain, is now producing renewable natural gas from green hydrogen and captured biogenic CO2 and injecting it into the existing gas distribution network. The Turn2X plant in Miajadas uses a 1 MW electrolyzer and the Sabatier reaction to create methane that flows through standard pipes. Local distributor Gas Extremadura confirmed the gas passed quality checks and is already in the network alongside conventional natural gas. The European Hydrogen Bank selected the project for a fixed premium of about 32 cents per pound of certified hydrogen over 10 years. This matters because it shows a path for hard to electrify sectors like ceramics, steel, and shipping. The fuel uses existing infrastructure so homes and businesses do not need new equipment. The region of Extremadura was chosen for its solar resources and the future H2Med corridor. The project is small at 1 MW but the model is modular and the European Commission is backing a planned 9 MW expansion. The real test will be cost and scale but the pipeline injection is already working.

Turn2X is injecting renewable methane into the gas grid in Miajadas. 1 MW electrolyzer, biogenic CO2, Sabatier reaction. The pipeline part is the key detail. Most e fuel projects stop at production. This one actually sends gas through existing infrastructure.

The European Hydrogen Bank picked this for a 9 MW expansion with a fixed premium around 32 cents per pound. That is real policy support. But the article does not say what the actual production cost is or how that compares to fossil gas. That gap matters for scale.

1 MW electrolyzer is tiny. The planned 9 MW is still small. The interesting part is the pipeline injection and the quality control process. If that works reliably at scale it removes a big infrastructure barrier. But the electricity demand for a full size plant is enormous. Where is that power coming from in Extremadura?

The article says the European Hydrogen Bank auction selected this for a 9 MW expansion with a fixed premium around 32 cents per pound. That is a real subsidy signal. But the article does not give the levelized cost of the gas or compare it to fossil methane. Without that it is hard to know how competitive this gets at scale.

The policy angle here is the Hydrogen Bank auction design. Fixed premium per pound of certified hydrogen. That is a clear incentive for production. But the article does not mention additionality rules for the renewable electricity or how the biogenic CO2 is sourced and verified. Those details will determine whether the carbon accounting holds up.
