Improving people’s lives through connected sustainable infrastructure
Costain Group plc is an engineering consultancy with over 70 years in hydrogen, CCUS, gas separation and processing. It is helping to realise the transition to hydrogen through its work on hydrogen production and transportation concepts, and carbon capture and storage schemes. From large-scale industrial clusters to community-based schemes, they identify opportunities for decarbonisation and develop projects from initial concept until completion.
Why join The Solent Cluster?
Costain Group joined The Solent Cluster because, as well as being involved in other clusters elsewhere, it is keen to collaborate with established companies able to drive technological innovation, and push for change. It is looking forward to bringing knowledge and experience to the Solent in an upfront advisory capacity and sees its role as sharing information to help shape how The Solent Cluster is going to operate with a keen focus on originality and ‘thinking outside the box’.
Accelerating the transition to a Net Zero carbon economy
Costain focuses on partnering with businesses to help them accelerate the transition to a Net Zero carbon economy. It achieves this by enabling them to fully understand their carbon impact, identify where their carbon hotspots are, and encourage profound transitions to low carbon electricity or fuel. Costain has successfully driven the cluster activity across the UK in Scotland, England and Wales. They are an established leader in clustering; bringing together academia, industry and local government to successfully obtain cluster funding to advance the regional and national ambitions.
Their carbon services deliver in three areas that enable businesses to take practical, swift and cost-effective action on climate change: the reduction of embedded and operational carbon, the improvement of energy efficiency and resilience and the transition to hydrogen, renewable electricity and Carbon Capture and Storage (CCS).
Costain is a technical adviser on the processes, systems and technologies that will enable the widespread adoption of hydrogen during the transition to a zero-carbon energy system. Its experts support business case development as well as the design, implementation and operation of associated infrastructure and network upgrades.

It has experience of a range of carbon capture technologies, particularly low temperature separation, and is continuing to develop innovative processes. The unusual physical behaviour of high pressure CO₂ is a particular consideration in the design of systems for carbon capture, usage and storage.
Costain’s ambition is to become a Net Zero business by 2035, while enhancing biodiversity and natural capital, and it has plans in place to deliver this.
Exciting new innovations are in progress in the Natural Resources Division, for example, the industrial Hydrogen accelerator fund. Costain is also partnering with Wales and West Utilities and Welsh water looking at innovative ways to treat wastewater and take hydrogen and generate hydrogen from various technologies.
