Life Cabezo Green H2

MW-scale green hydrogen production plant to decarbonize the treatment of meat by-products in Spain.

The project aims to replace the natural gas used as a fuel to treat meat by-products with hydrogen (H2) technology to lower CO2 emissions.

An H2 production plant based on a water electrolysis technology will be installed in Muel (Zaragoza), one of Spain’s most significant industrial areas.  The production plant will be powered directly from the nearby 23.25 MW Cabezo San Roque Wind Farm and is expected to produce more than 100 tonnes of green H2 per year to decarbonise local industry.

The oxygen produced as by-product from the electrolysis process will be used rather than vented out to the surroundings, further avoiding the emission of greenhouse gases.



The goals of our project are:


Deliver Spain’s First MW-scale green H2 production plant.

evelop Spain’s first MW-scale green H2 production plant using electrolysis technology. The plant will be able to produce more than 100 tonnes of green H2 per year. A 1 MW PEM electrolyser will be scaled up and developed with Spanish technology.


Use Green H2 in the treatment of meat by-products.

Integrate green H2 into the treatment and recovery of meat by-products at RESIDUOS ARAGON (RS), achieving at least a 5% volume of green H2 in the natural gas stream supplied as a fuel to the process. How the existing boilers can be adapted and modified to incorporate higher levels (up to 20%) of hydrogen will be analysed.


Reduce LNG consumption.

Using hydrogen will reduce LNG consumption by more than 900 MWhHHV/year, a reduction of more than 600 tons of CO2eq/year in emissions from the site.


Demonstrate replicability strategies.

Demonstrate the scalability of the technology and how it can be replicated for other industrial sites across Europe to accelerate the reduction of CO2 emissions and fight climate change.


We have a clear action plan to ensure we reach our objectives.


In the preparatory phase (A1) we aim to carry out site preparation and request the permits required. These actions will feed into the implementation phase of the project, facilitating the final design, the construction and the operation of the prototype plant in different scenarios.

During the implementation phase, the plant will be designed, constructed, commissioned and validated (actions C1, C2, C3 and C4) in Zaragoza and operated for an initial period of one year. Tests will be carried out to evaluate the H2 produced and used in the process to ensure the anticipated reduction of greenhouse gases is achieved.  When the project comes to an end a business plan will be developed and a study into how the technology can be transferred to and replicated in other European countries (C5 and C6) will be carried out.
