Low-carbon
structural steel. Made in the UK.

A new electric arc furnace steel mill for the UK, built to run on renewable power. First steel planned for 2029.

A new era of electric steelmaking

Recycled UK steel, melted with electricity and reforged to help build UK’s future

More UK steel. More UK jobs. Less carbon.

The project

First steel planned for 2029.

Our site will be announced shortly. From there, consents and construction lead to first steel.

We thank the UK Government for the UK Steel Strategy and the frameworks that support it, from the National Wealth Fund to faster grid connections and planning reform. Together, they make new investment in UK steelmaking possible.

Structural sections

Universal beams and columns, channels and angles: the frame of a building.

Round bars

The main shaft of a wind turbine starts as a round bar.

Sheet piles

Steel walls that hold back earth and water.

Angles

The frames of the energy transition: pylons, solar farms and substations.

Building with Greensteel products

Faster frames. Lighter foundations.

Using steel framing can mean faster construction and less structural weight. Factory-made components arrive ready for assembly, while lighter frames can reduce the demands placed on foundations.

Speed

Steel frame16 weeks
Concrete frame28 weeks

In one UK office study, the steel frame went up 12 weeks faster than concrete.

Weight

Steel frame1.0
Concrete frame1.5

Concrete frames weigh about half as much again. A lighter frame needs smaller foundations.

Impact

Good for the economy.
Good for the environment.

For the economy

  • New UK steelmaking capacity
  • Hundreds of skilled jobs
  • Investment in UK suppliers and communities
  • Less reliance on imported steel

For the environment

  • About a quarter of the blast furnace route's emissions
  • Used steel recycled at home, not exported
  • A furnace built for renewable power
  • Every tonne traced and verified

Powering the furnace

Powered by electricity. Built for renewables.

Our electric arc furnace runs on electricity. Greensteel’s advanced power electronics allow it to draw power from the grid and make use of renewable energy from wind and solar, supported by battery storage.

Lower carbon steelmaking

Less carbon. Same strong steel.

World-leading, low-carbon green steel. An electric arc furnace running on recycled steel emits around a quarter of the carbon of the blast furnace route.

The electric arc furnace difference

Blast furnace route2.66 t
Global average, all routes2.18 t
Electric arc furnace, recycled steel0.71 t

CO2e per tonne of crude steel. World Steel Association global averages, 2024.

73%

less CO2e per tonne than the blast furnace route.

1.5 t

of CO2 avoided for every tonne of recycled steel used.

100%

recycled steel is possible in an electric arc furnace.

Building a circular steel economy

Old steel, reforged.

Every year the UK generates 10-11 million tonnes of scrap steel, but only around 20% is recycled into new steel. Greensteel will help close the loop, turning recycled steel into new steel for UK infrastructure.

Jobs

Bringing steelmaking home.

Seven in every ten tonnes of steel the UK uses are imported, and the skilled work goes with them. Every tonne forged here keeps jobs, wages and skills in UK communities.

Hundreds

of skilled jobs at the mill, and many more in construction and the supply chain.

32%

higher pay at UK steelmakers than local median wages.

40–50%

of UK demand met by UK steel: the Government's aim, up from 30%.

Careers that stay in the UK

Operators, metallurgists, engineers, maintenance, automation, quality and logistics.

Skills for the next generation

Apprenticeships, retraining and partnerships with colleges and universities.

Sovereign capability

The ability to make the steel the UK needs, in the UK, whatever happens to global supply.

Steel you can verify

Quality steel you can trace from the start

Every Greensteel product will be traceable from production to project, via a digital passport: where it was made, what from, its certificates and its verified emissions.

  • Certificates in a scanMill certificates to BS EN 10204, on site and in the office.
  • Carbon you can reportVerified emissions for each tonne, ready for embodied carbon reporting.
  • Ready for what comes nextDesigned for emerging digital product passport rules.
