In late July 2026, Portugal’s Sines refinery secured a combined €229 million investment. Galp Energia allocated €109 million for a refinery upgrade as part of its €442 million energy‑transition programme, while Spanish firm Catalyxx announced €120 million to build a renewable‑chemicals plant that will convert bio‑ethanol into debutanol, hexanol and octanola, aiming to cut CO₂ emissions by about 105,000 tonnes per year.

A week later, the Association for Economic Development (SEDES) warned that Galp’s planned merger with Spain’s Moeve could jeopardise the strategic value of the Sines refinery. The merger would integrate Portugal’s sole refinery into an Iberian network, potentially making the country dependent on external decisions for refined‑fuel supply and risking loss of technical know‑how, research capacity and future investment. The Portuguese government said it was monitoring the process to protect national energy security.

On 5 August 2026, the Central Committee of Workers at Petrogal publicly challenged Prime Minister Luís Montenegro to give a clear stance on the refinery’s future and the pending Galp‑Moeve merger. Echoing SEDES, the workers’ body warned that the deal could threaten the strategic asset and Portugal’s energy autonomy, and urged the government to use its powers to safeguard the plant and the jobs of Petrogal employees.
