Unlocking Hydrogen’s Potential
With the growing emphasis on decarbonisation, hydrogen and its derivatives play a pivotal role in reducing carbon emissions across industries. The urgency of the energy transition demands significant infrastructure repurposing, particularly of our pipeline networks, to reduce emissions, create jobs, and drive sustainable development.
Hydrogen demand is estimated to reach 115Mt by 2030, so operators must carefully consider end-to-end solutions that support sustainable growth. With more than 70 years of experience in energy infrastructure and a proven track record in delivering large-scale projects, Penspen supports customers with engineering, project management, and technical services at all stages of the hydrogen value chain. With CCUS central to the production of blue hydrogen, Penspen also has experience in CO2 design and repurposing, providing clients with a single consultancy for both hydrogen and CO2.
Our range of services across the hydrogen market includes:
Advisory and Consultancy
