200m tall concrete turbine bases could be 3D-printed : A plan to develop wind turbines with 3D-printed concrete bases, reaching record heights up to 200 metres is being muted by a consortium of energy leaders.

The 3D construction printing firm COBOD, GE Renewable Energy, and the building materials company LafargeHolcim, promise while lowering energy and construction costs, this innovative solution will increase renewable energy production.

Taller towers can capture higher speed wind currents and therefore generate more energy. but as they are traditionally built in steel or precast concrete bases, wind turbine towers have typically been limited to a height of under 100 metres.

Printing the base directly on-site with 3D-printed concrete technology will enable the creation of larger bases and cost-effective taller hybrid towers, says the group.

Advanced Manufacturing Technology Leader for GE Renewable Energy, Matteo Bellucci said: “3D printing is in GE’s DNA and we believe that large-format additive manufacturing will bring disruptive potential to the wind industry.”

Founder of COBOD International A/S, Henrik Lund-Nielsen added: “With our groundbreaking 3D printing technology combined with the competence and resources of our partners, we are convinced that this disruptive move within the wind turbines industry will help drive lower costs and faster execution times, to benefit customers and lower the carbon footprint from the production of energy.”
