Providing Energy. Improving Lives.

The Humber Refinery is playing its part of the UK’s decarbonisation efforts.

‍

As a part of the UK Government’s net zero ambition, the Humber Refinery is on a journey to become the Refinery of the Future. With proposed plans for a number of projects including to implement a first-of-a-kind FCC carbon capture project, the Humber Refinery is part of Humber Zero, a world-scale concept to reduce UK industry carbon emissions, saving up to 8 million tonnes of CO2 by 2030 from the Immingham industrial area.

‍

On top of this, the Humber Refinery is the UK’s only refiner producing Sustainable Aviation Fuel at scale. It is also the only European facility producing battery anode coke, which forms a critical component for lithium-ion batteries used in electrical vehicles and in consumer electronics. Our current production of battery anode coke is equivalent to placing 1.3 million EVs on the road every year, and we are developing multiple projects to expand this capability.
