For a Greener Energy Future

Decarbonisation of the energy sector requires urgent action on a global scale, and the energy industry as we know it is changing. As our sector shifts from fossil-based systems of energy production and consumption to renewable energy sources, like wind and solar, the need for smart partnerships in order to accelerate the transition to a carbon neutral society is of great importance.

Penspen has been at the forefront of the energy industry for 70+ years, delivering more than 15,000 projects in over 100 countries. By helping countries access lower carbon fuels and by extending the useful life of existing energy infrastructure, we help bring cleaner energy to millions of people in thousands of communities across the Middle East, Africa, Asia, Europe, the UK, and the US.

Our Main Areas of Focus
Our primary capabilities include engineering consultancy for the development of new hydrogen & CO2 infrastructure, repurposing of existing infrastructure for hydrogen & CO2, operating with hydrogen & CO2, and infrastructure maintenance services.

The Hydrogen Economy
Our four main hydrogen sectors includes: H2 supply and carbon sequestration (green & blue hydrogen), technology (hydrogen production, carbon capture), distribution & storage, and end users. Explore our hydrogen capabilities to find out how our experts can make the hydrogen economy work for you.
