Molecules such as CO2, bio-LNG and green ammonia have a big role to play in the energy transition and decarbonisation of hard-to-electrify sectors in the future. That is why Enagás has launched Scale Green Energy.

This subsidiary will be responsible for developing other infrastructure and services for decarbonisation in areas such as CO2, bunkering and small-scale LNG and Bio-LNG, the use of waste cold generated in the LNG regasification process, green hydrogen for mobility and renewable ammonia.

 

Scale Green Energy's lines of action

Development of CO2 pipelines, liquefaction plants and transport vessels, promoting the creation of logistics hubs around LNG plants.

Enagás has signed collaboration agreements with various companies in the cement sector in Spain to jointly promote projects that favour the transformation, greater competitiveness and decarbonisation of this CO2-intensive industry, where emissions are difficult to reduce.

Scale Green Energy and Enagás have submitted the ‘CO2necta’ project to the European Commission's Innovation Fund call for proposals in April 2025, together with Holcim and Saggas, the ‘MOSUSOL NetCO2’ project, together with Cementos Molins, and the ‘COnet2 Sea’ project for the construction and operation of a 20,000 m3 CO2 transport ship.

 

Shipbuilding and maintenance for LNG bunkering and other renewable molecules, such as Bio-LNG, to help decarbonise maritime transport.

Scale Green Energy has a 50% stake in two vessels in operation, the Haugesund Knutsen and the Levante LNG, and a 100% stake in another vessel currently under construction, the Alisios LNG. The company is also developing small-scale LNG export terminals, such as the one located in Ravenna (Italy), which has been operational since the end of 2021.

The company also promotes the use of technology to capture sustainable waste cold generated during the LNG regasification process at its regasification plants. This waste cold is then used in various processes that require intensive cooling, such as renewable gas liquefaction plants. As part of this effort, Enagás, Veolia, and the Barcelona City Council launched the first sustainable urban cold recovery network at the Enagás terminal in the Port of Barcelona in late 2024. They're working together to adapt this solution to other LNG infrastructure in Spain and around the world.

Furthermore, Enagás is participating in the development of the sustainable cold logistics hub project at the Port of Huelva. The project aims to supply sustainable cold to a network within the Port for distribution to logistics and food companies, optimising energy efficiency and strengthening the competitiveness and sustainability of the local environment.

Creation and management of green hydrogen supply infrastructure for both light and heavy vehicles, with a focus on mobility segments that are difficult to electrify, to help decarbonise road transport.

The company is promoting the 'ECOhynet' project and in February 2025 obtained 100% of the CEF funds requested to develop six hydrogen refuelling stations in Spain, a number it plans to double by 2030.

 

Development of ammonia port infrastructure in the area surrounding Enagás' regasification plants, with the aim of advancing a multi-molecule model that develops alternative, decarbonised energy solutions.
