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.

Over the past 60 years Penspen has been at the forefront of the energy transition, delivering over 10,000 projects to more than 100 countries around the world. By helping nations to access lower carbon fuels and by extending the useful life of existing energy infrastructure, we bring cleaner energy to millions of people, in thousands of communities across the globe.

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. Speak to our team of experts to find out how the hydrogen economy can work for you.

Penspen at COP

Decarbonisation of Energy Demand - COP28

The future energy mix of most places will include both renewable electricity and zero emissions hydrogen. This mix will vary by location, but in all places will demand new infrastructure and investment alongside the transition of the electrical grid.

Infrastructure for Future Flight - COP28

The scale of the Energy Transition in aviation requires new infrastructure to be planned for major airports within the coming years, if promises of sector decarbonisation are to match the requirements of the Paris Agreement.

Energy Transition Panel - COP27

Peter O’Sullivan, Penspen CEO, addressed COP27 delegates on hydrogen and the energy transition, sharing knowledge on how a significant scale-up of low carbon hydrogen is required to decarbonise hard to abate sectors – reducing both carbon emissions and production costs.
