Redexis receives authorization from MITECO to carry out the first green hydrogen injection installation in Spain

Redexis, a comprehensive energy infrastructure company, has obtained administrative and execution authorization from the Ministry for the Ecological Transition and the Demographic Challenge to install the green hydrogen injection system in the position of one of its primary transport gas pipelines, specifically the one located in San Juan-Cas Tresorer-Son Reus, on the island of Mallorca.

This project represents a historic milestone for the sector, given that it is the first renewable hydrogen injection facility authorized in the Spanish gas system and will allow this vector to be injected into the natural gas network that supplies the entire island of Mallorca, made up of time for more than 160 kilometers of gas pipelines and 1,150 kilometers of distribution networks.

The facility has the capacity to inject up to 2% hydrogen, which means 575 tons/year. In addition, since it is green hydrogen, it will imply a reduction in emissions of up to 21,000 tons/year of CO2 derived from the production capacity of the Lloseta plant, which will initially be 300 tons/year.

The mixture of green hydrogen and natural gas is the key element of the project since, in addition to being the first facility of this type to be carried out in Spain, it is one of the largest in Europe by capacity. To carry it out, Redexis will implement a technologically advanced and pioneering solution based on the mixture of gases through a static mixing system that allows indirect dilution of the hydrogen and natural gas streams.

The hydrogen pipeline that will feed this injection system is currently in the process of processing before the General Directorate of Energy and Climate Change of the Balearic Government and its authorization is expected in the short term. Once authorized, the construction will be carried out and the injection of green hydrogen into the natural gas networks of Mallorca will begin, being a very relevant step in the advance towards a zero-emissions society (NetZero).

For Diego Sánchez Muslera, director of Engineering, Offers and Execution of Redexis, “this injection will bring closer and lower the costs of energy vectors such as hydrogen to segments such as industrial and domestic. This project will allow the production of hydrogen to be injected into the most efficient and economic means of transport, since it is already available: the natural gas transport and distribution networks”.

This installation that Redexis will carry out is aligned with the decarbonization strategy of the economy and of the company itself which, as announced in its Energía26 plan, is going to promote renewable energy projects with large investments focused on the energy transition, and where the current Redexis networks play an essential role in being able to transport renewable gases such as hydrogen.

This infrastructure is part of the Green Hysland European grant project, made up of more than 30 organizations, companies and technology centers, including Enagás, Acciona Energía and Cemex. The European Union, through the Clean Hydrogen Partnership, has committed 10 million euros to support the deployment of the necessary infrastructures to make Mallorca’s renewable hydrogen ecosystem a reality in the 2021-2025 period, and brings together all the core elements of the hydrogen value chain through production, transportation and distribution infrastructure, and the end use of renewable hydrogen.
