We are committed to improving lives, and that is our promise to our employees and communities. We are sustained by the backgrounds and experiences of our diverse teams, which reflect who we are, the environment we create and how we work together.

Our company is built on values of safety, honour and commitment. We call our cultural mindset Our Energy in Action, which we define through four simple, intuitive behaviors: We work for the greater good, cultivate an environment of trust, seek different perspectives and pursue excellence.

Our employees are the heart of our success, and there is a reason why we continue to attract great talent and it’s not just the excellent benefits package, or the opportunities for personal growth, it’s also the caring and committed culture of the organisation that makes everyone feel like they can bring their authentic self to work and be truly part of our team.

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.

We are on an exciting journey, are you ready to join us?
