ALBA Project
The expansion includes the construction of two new plants, one for linear polyethylene and the other for polypropylene, both polymeric materials.
Renewable hydrogen as an energy source
The hydrogen produced in H2ALBA will supply the new units.
H2ALBA Project
It is estimated that it will produce 600 t/y of renewable hydrogen and reduce up to 6,000 t/y of CO2 emissions.
The H2ALBA project is a fundamental pillar for the energy transition

The technologies of both plants ensure maximum energy efficiency, integrating the self-consumption of photovoltaic energy and hydrogen by electrolysis, are leaders in the market, and the first of their kind that will be installed in the iberian peninsula.

The complex will also have new logistics facilities, incorporating the possibility of using the railroad and connection to the port of Sines, which will allow multimodal logistics, optimizing the connection with the European market, as well as reducing the carbon footprint of product transportation.

This project will contribute to greater integration and diversification of our industrial area, strengthening its leadership in Europe.
