Supporting Galp's decarbonisation plan for the Sines refinery & the ultimate goal establishing a Green Energy Hub

io consulting (io) is pleased to announce the award of a Feasibility Study by Galp for their green hydrogen production plant located at the Sines Refinery in Portugal. The project is an important component of Galp’s decarbonisation pathway for the Sines Refinery and will help to transition the existing grey hydrogen to green hydrogen. 

Galp’s decarbonisation plan for the Sines refinery has the ultimate goal of transforming the refinery into a Green Energy Hub. To achieve this goal Galp will optimise the efficiency of the refinery and also produce low-carbon products such as biofuels. Green Hydrogen production will also be utilised at the hub to decarbonise the refinery’s hydrogen source which will help Galp realise a significant operational carbon footprint reduction by 2030.

Galp is currently developing a 100 MW green hydrogen project that is targeting a 2025 start-up, and have plans to increase the installed capacity in the second half of the decade. This expansion would allow Galp to not only replace the Sines grey hydrogen consumption but also produce green fuels and other hydrogen derivatives. 

This study will see io deploy its model-based system engineering (MBSE) and extensive hydrogen experience to techno-economically assess the core optionality of the project which includes the mix and size of the power sources, the use of hydrogen and energy storage, facility installed capacity, offtaker selection, and the project phasing approach. The results from this study will identify the optimum approach for the project that aligns with Galp’s value drivers.
