Enagás and Terresis Centro de Magnesitas Navarras have signed a collaboration agreement to develop joint projects responsible management of CO22 and industrial decarbonization in Spain, with an estimated emissions reduction capacity of around 340.000 tons per year.
The pact combines the deployment of capture technologies at the Zubiri plant (Navarra) by Terresis with the analysis by Enagás of solutions for the transport, the liquefaction and storage and loading onto ships from its regasification terminals, geared towards later use or permanent storage.
Scope of the agreement and next steps

Understanding contemplates a comprehensive feasibility analysis throughout the entire CO value chain2 —in the technical, organizational, financial, contractual and legal aspects—, as well as the infrastructure design necessary for its deployment.
The two companies will also explore the possibility of jointly apply for funding opportunities, both national and European, with the aim of accelerating the timetable and providing certainty for investment.
In the industrial sector, Terresis will deploy solutions for CO capture2 at their factory in Zubiriwhile Enagás will assess the conditioning, logistics and the CO shipment2 by sea from their terminals as a preliminary step to their use or final storage.
Terresis Centro de Magnesitas Navarras, integrated into the mining sector, is dedicated to magnesite extraction and the manufacture and marketing of its derivatives for industries such as steel, agriculture and the environment; for its part, Enagás has extensive experience in the development, operation and maintenance of energy infrastructures, including several regasification plants in Spain.
CO logistics chain2From Zubiri to the Enagás terminals

The collaboration draws a complete CO logistics chain2 which begins at the emission source and ends in its final use or storage, taking advantage of the capillary action of the regasification terminals as nodes for loading ships.
- Capture Originally manufactured at the Zubiri factory (Navarra).
- Compression/liquefaction for its conditioning and safe handling.
- Transport towards Enagás terminals with intermediate storage capacity.
- Loading ships in authorized regasification facilities.
- Final destination: use as raw material or permanent storage.
From a business perspective, Enagás emphasizes its commitment to reducing the carbon footprint in sectors that are difficult to address, and values that synergies with an industrial benchmark like Terresis facilitate innovation and competitiveness in the sustainable management of CO2.
For its part, Terresis highlights that industrial decarbonization requires strategic alliances with financially sound partners to accelerate the transition to a more sustainable model, and considers cooperation with Enagás to be key for an industry decarbonized and competitive.
Interest in these solutions is growing in Spain: in the non-binding process Call for Interest presented by Enagás in the Second Hydrogen Day (January 2024) they identified themselves 37 companies interested in capturing CO2 (potential of 10,4 million tons per year) and others 53 companies that are looking for infrastructure for their transport and storage.
The joint initiative of Enagás and Terresis lays the groundwork for deploying a comprehensive solution for CO2 capture, transport and storage2 from Navarra, with a potential impact of 340.000 t/year and a roadmap that includes a feasibility study, infrastructure design and financing options for its implementation.
