Cartagena

CHYNE project

Together with Enagás Renovable, Repsol will lead the CHYNE consortium with the aim of deploying a 100 MW-capacity electrolyzer, at the Repsol Petróleo Complex in the Cartagena industrial area.

This project is part of Repsol's strategy to lead the energy transition and reduce carbon emissions. Renewable hydrogen will be produced through the electrolysis of water, using electricity coming from renewable sources, which ensures a process free of CO₂ emissions.

The facility will be designed to produce 1.7 tonnes of renewable H₂ per hour, generating renewable hydrogen and oxygen for local consumers and will prevent up to 167,000 tonnes of CO₂ being released per year. As a result, the project stands to be a significant contributor to the widespread adoption of renewable hydrogen, with an important impact at an environmental, economic, and social level.

Objectives

The objectives of this project are:

Contribute to achieving the national renewable H₂ generation objective of 12 GW electrolyzer power according to the PNIEC 2023-2030 (updated in Sep. 2024).
Reduction of CO₂ emissions associated with the generation of conventional H₂ (gray/fossil) by steam reforming of hydrocarbons.
Reduce consumption and, therefore, importation of fossil natural gas, reducing energy defendence outside Spain.
Promote the creation of a Hydrogen Valley in the area that allows the reduction of CO₂ emissions not only in the industry sector, but also in sectors such as transportation or domestic.

CHYNE is also part of the European Hydrogen Backbone, which positions it as a key player in the hydrogen transmission facilitation among countries in the EU from the Valle de Escombreras, in Cartagena.

The Cartagena project not only represents a significant advancement in the production of renewable hydrogen in Spain, but has also been recognized as an Important Project of Common European Interest (IPCEI). This recognition highlights the relevance of the project for the innovation and competitiveness of European industry, as well as its contribution to the climate and energy goals of the European Union.

The hydrogen produced in Cartagena will be used in diverse industrial and mobility applications, promoting a more sustainable and decarbonized economy. Moreover, the project will generate employment and will promote technological development in the region, positioning Cartagena as an innovation hub in clean energies.
