Green hydrogen is experiencing significant growth, driven by factors linked to the energy transition, sustainability, and the urgent need to reduce greenhouse gas emissions.

Scale Green Energy, an Enagás subsidiary pioneering in the deployment of clean technologies, has developed a cutting-edge project for the competitive production and use of certified green hydrogen, guaranteeing its renewable origin. The facility is located at Enagás’ regasification plant in Palos de la Frontera (Huelva).

The Effi Solar Green H₂ Portuario project aims to reduce the terminal’s carbon footprint by replacing natural gas with hydrogen in specific processes.
It includes a modular electrolyzer system made up of seven interconnected cabins.

A 1 MW photovoltaic solar plant was also built. The electricity required to produce green hydrogen must come from renewable sources — mainly solar and wind — both abundant in Andalusia.

The produced hydrogen is stored in a low-pressure tank and then transported by pipeline to the LNG plant.

Scale Green Energy awarded Montrel the electrical installation works, strengthening our expertise in this field.

Additionally, the Montrel team was responsible for the hydrogen and water process piping, the power line installation feeding the electrolyzer, as well as the mechanical and electrical interconnection of all cabins comprising the electrolyzer.
