Enagás, Holcim, and Saggas have announced an agreement for the joint development of an innovative project aimed at decarbonising CO2-intensive industrial processes, as part of a technical visit to Sagunto.

The CEO of Enagás, Arturo Gonzalo; the CEO of Holcim Spain, Ricardo de Pablos; and the General Director of Saggas, Santiago Álvarez, unveiled the “CO2necta Project,” which will create an integrated value chain for CO2 capture, transport, and storage in the Valencian municipality of Sagunto. This initiative will prevent the emission of more than 560,000 tonnes of CO2 annually in the Valencian Community.

The project will establish a CO2 capture plant at Holcim’s Sagunto factory, with the captured CO2 being transported via Enagás’ infrastructure to the Saggas terminal located in the Port of Sagunto, where it will undergo a liquefaction process. Once in liquid form, the CO2 will be transported by ships to its final geological storage.

Strategic Impact and Collaboration Model

The consortium formed by Enagás, Holcim, and Saggas is based on the establishment of a pioneering circular economy model—the biogenic portion of the captured CO2 will be used to produce e-methanol and other biofuels—and decarbonisation in the municipality of Sagunto and its surrounding areas. CO2necta will boost the local and national economy, particularly in hard-to-abate sectors.

CO2necta exemplifies collaboration among leading companies committed to transforming industry and decarbonisation through innovative technologies, creating a value chain that could serve as a model for other sectors.

Enagás CEO Arturo Gonzalo emphasised, “CO2necta contributes innovative solutions to advance our decarbonisation commitments together, especially in strategically important hard-to-abate sectors.” He added, “This pioneering project drives sustainable CO2 management in Spain and Europe, highlighting the role of strategic infrastructure such as Saggas in leading industrial decarbonisation and enhancing the competitiveness of the sector.”

In this regard, Ricardo de Pablos, CEO of Holcim Spain, highlighted that “industrial decarbonisation requires cross-sectoral alliances and projects that allow for the development of the CO2 value chain, with transport infrastructure and logistical hubs to foster economies of scale, making industrial transformation possible.”

During the visit, Arturo Gonzalo and Ricardo de Pablos toured the Saggas Liquefied Natural Gas terminal—owned 72.5% by Enagás—and the Holcim factory in Sagunto, key infrastructures in the project’s value chain.
