The Consortium

Entara is a Global Asset Manager for refining infrastructure. Entara was established by former executives of Crossbridge Energy who have a track record of managing and optimising refinery assets, including the Fredericia refinery in Denmark.



Trafigura is one of the world’s largest suppliers of energy and commodities, operating in over 150 countries and trading over 5.5 million barrels of oil and petroleum products every day. Trafigura has a 30-year history of working with refineries through direct investment, capacity utilisation and supply and offtake.



The Fos-sur-Mer refinery project

Fos-sur-Mer refinery is a historic site that has contributed to providing secure and affordable energy to the region since operations commenced in 1965.

With this proposed acquisition, Rhône Energies plans to capitalise on the refinery’s existing skilled teams and strong manufacturing performance. The company aims to further improve margin capture, crude flexibility, process utilisation and to maximise high value products, while investing in personnel and process safety.

Rhône Energies intends to invest in the sustainability of the site to reduce its carbon intensity footprint while also investing in growth projects enabling further co-processing of biogenic feedstocks to produce renewable fuels.
