There’s a quiet revolution unfolding beneath our feet and it’s emerging layer by layer.
As infrastructure owners and contractors face increasing pressure to cut carbon emissions, trim costs, and enhance delivery timelines, low carbon foundations are proving to be a game‑changer. At Hyperion Robotics, our mission is to make this new generation of sustainable foundations the backbone of sustainable infrastructure.
This post explains what low-carbon foundations are, why they matter, especially in the context of our ongoing pilot with National Grid, and what the future holds.
What are low-carbon foundations?
Low-carbon foundations are engineered concrete bases using Modern Method of Construction such as additive manufacturing to drastically reduce embodied carbon while maintaining full structural performance.
Unlike traditional precast elements, which are typically over-engineered and require steel formwork, low-carbon foundations use just the right amount of material, precisely placed, without moulds or waste. Hyperion’s approach integrates smart design, additive manufacturing and proprietary low-carbon concrete to deliver strong, compliant, and sustainable foundations fit for modern infrastructure.
The problem with traditional foundation construction
Foundations are critical to infrastructure safety and durability — but conventional construction methods are among the most carbon-intensive parts of any project. Common challenges include:
- Excessive cement use and high CO₂ emissions
- Over-engineering and material waste
- Manual labour constraints, site delays, and weather risks
- Heavy transport and logistics requirements for precast units
- Limited flexibility to tailor design to specific soil or site conditions
For utilities and infrastructure operators managing multi-site upgrades, even small efficiency and carbon gains can scale into major system-wide benefits.
How low-carbon foundations are built
At Hyperion Robotics, our process begins with digital design and structural engineering, followed by robotic printing at or near the site. Here’s how it works:
- Digital twin foundation design – tailored to exact site conditions
- Optimisation – structural analysis and material minimisation using FEA
- Automated printing – robotic arm extrudes low-carbon concrete in precise layers. Steel reinforcement is efficiently integrated at pre-programmed points, ensuring structural integrity without interrupting the print workflow.
- Curing and QA – monitored for strength, tolerances, and compliance
- Installation – ready to install with no formwork or complex logistics
This workflow cuts manual effort, removes waste, and allows for repeatable, scalable deployment across multiple sites.
National Grid partnership — a live pilot
In early 2025, Hyperion Robotics partnered with National Grid to field‑test low-carbon foundations for substations. The foundations are being designed and produced in Finland, with physical testing planned in partnership with the University of Sheffield and National Grid’s Deeside Centre in 2025.
While this is still an active pilot and benefits are projected, it’s worth noting that if scaled across the network, the initiative could deliver:
- Up to 705 tonnes less concrete
- Around 323 tonnes in CO₂ savings
- An estimated £1.7 million in consumer benefits
This is in addition to reductions in soil displacement, foundation weight, and site labour.
Environmental benefits — what studies show
Research consistently highlights the carbon-saving potential of low-carbon concrete, utilising additive manufacturing:
- Hyperion’s micro‑factories use 75 % less structural material, and support recycled industrial waste (slag, fly‑ash, tailings) to lower embodied CO₂ by up to 90%.
- UKGBC confirms our method combines large‑scale robotic printing with low‑carbon mixes (zero‑cement options) to deliver ~70 % lower embodied carbon, ~50 % faster lead times and ~30 % cost savings.
- Academic reviews note that optimised 3D printed concrete structures can halve material use and reduce LCA global warming potential, even more so in complex shapes.
These findings support how Hyperion’s approach – combining material science, structural optimisation, and automation – can significantly advance sustainability goals.
Economic benefits — reducing cost across the value chain
Low-carbon foundations offer multiple cost-saving levers across design, production, and installation:
- No formwork or steel moulds, which reduces materials and setup costs
- Optimised structural design means less concrete per unit, lowering material spend
- Digital fabrication removes costly human error and rework
- On-site or near-site production using localised micro-factories reduces transportation costs and crane hire
- Faster installation helps contractors avoid penalty charges or liquidated damages
When deployed across asset portfolios, these savings can translate into millions in avoided costs, as demonstrated in the projected savings from the National Grid pilot.
When applied across portfolios, these efficiencies can deliver millions in avoided costs — as evidenced by early results from our National Grid pilot.
Operational benefits — speed, precision, and flexibility
For asset owners and contractors working across multiple constrained sites, low-carbon foundations offer major operational advantages:
- Rapid production cycles — foundations can be printed in a matter of hours
- Just-in-time delivery — eliminates the need for stockpiling or waiting for precast supply
- Repeatability and standardisation — identical components can be reproduced with zero deviation
- Customisation — geometry, height, or cable channels can be adapted digitally
- Fewer site workers — ideal for constrained or remote sites with limited crew access
By integrating seamlessly into modern project workflows, Hyperion’s technology helps de-risk deployment, especially across multi-site infrastructure programmes.
Structural integrity and reinforcement – built to code
All Hyperion low-carbon foundations are fully code-compliant and structurally reinforced. Our designs are developed in line with UK building regulations and Eurocode requirements, with reinforcement incorporated strategically during the printing process.
By starting from a digitally optimised model, we reduce not just the volume of concrete, but the volume of reinforcement as well, maintaining correct structural ratios. In most cases, we use less steel in proportion to the material reduction, without compromising performance or durability.
This approach ensures our foundations remain strong, lightweight, and fully certifiable, ready for real-world infrastructure deployment.
Why utilities and infrastructure providers are paying attention
The utility sector is under mounting pressure to modernise its asset base while cutting emissions. The UK’s Net Zero Strategy and Ofgem’s RIIO framework both reward innovation and carbon reduction.
Low-carbon foundations offer a low-disruption, high-impact solution that aligns with:
- Net Zero infrastructure goals
- Cost-efficiency mandates
- Resilience and safety standards
With thousands of asset upgrades planned across power, water, and transport, the potential for rollout is massive.
Hyperion Robotics – built for scale, ready for impact
Hyperion Robotics is one of the few companies globally — and the only one focused specifically on critical infrastructure — delivering code-compliant, low-carbon concrete foundations at scale.
Our integrated model combines:
- In-house robotics and automation systems
- Low-carbon concrete research and development
- Structural engineering aligned with UK and EU standards
- Digital design, QA, and delivery under one platform
With plans to establish a dedicated UK manufacturing and R&D hub, we’re actively scaling our offering to meet growing demand across the utilities, energy, and infrastructure sectors.
What’s next for low-carbon foundations
From substations to renewable energy sites, transport hubs, and industrial platforms, low-carbon foundations are redefining how we build sustainably — from the ground up.
The foundation of tomorrow’s infrastructure will not only support structures above ground, but also the planet beneath it.
