Case Study: M55 Satellite Compound Trial Deployment
Customer: Costain
Costain hosted the deployment of an innovative new hydrogen-powered 100kVA generator at the M55 satellite compound, Preston site, where Hydrologiq were the project managers.
This government-supported deployment aims to uncover the practical challenges of replacing diesel with hydrogen, and paves the way for better emissions and working conditions on Costain’s active sites.
Hydrogen. Some believe it a wonder fuel touted with decarbonising energy-intensive areas of the world’s industrial or transport economy. Others focussed on the off-grid space view it as an energy carrier, capable of storing and transporting energy generated by renewables and delivering that energy to off-grid locations via existing road infrastructure.
Viewed like this, hydrogen becomes a good Net Zero replacement fuel for diesel, especially diesel used in generators. The benefit for construction and infrastructure projects is difficult to ignore, especially if the hydrogen generator used on-site is a fuel cell.
Fuel cells produce only water as a waste product, meaning that there are zero CO2e or NOx emissions at point of use, whatever colour of hydrogen used as a fuel.
- But how do end users like Costain access this solution?
- What carbon impact could adopting hydrogen have in the real world?
- And what operational impact would it have to current and future projects?

What next?
Explore Potential
Hydrogen has the potential to decarbonise large portions of heavy-duty off-grid power in construction by replacing diesel.
Paving the way for large-scale replacement of a fossil fuel.
Scale Green Hydrogen
Groups like Costain have the scale of demand to secure lower cost supplies of green hydrogen generated by emerging UK hydrogen producers.
Working Together
Tier ones could work with hydrogen industry stakeholders like Hydrologiq to build a practical roadmap to replacing diesel with alternative power sources like solar, wind, batteries and hydrogen.
More Trials
Longer trials where hydrogen is directly replacing diesel can showcase the positive carbon impact of using hydrogen.
“2022 heralds a new age for generator power. The diesel engine has been around since the 1800s, so it’s about time we embraced new technology to respond to a modern world where air quality and noise pollution are top of the agenda. Everyone at Hydrologiq is proud of our collaboration with Kier Highways to take tangible steps towards this new reality today.”
