Wind turbine towers produced on demand
This project focuses on providing solid proof that a) 3D printing can be used to manufacture tall wind turbine towers, b) it can be done economically and technically feasible, c) 2 design concepts for towers manufactured by 3D printing receive approval. A 10-meter-tall pilot tower will be manufactured to prove the feasibility of the 3D printed UHPC.
The aim of this pilot study is to create the fundamental documentation showing the potential of manufacturing - in a price- competitive way – onshore tall concrete wind turbine towers by means of 3D concrete printing (3DCP).
Large-scale 3DCP has been under development over the last decade and is becoming a reality in the construction sector. However, wind turbines are exposed to extreme loads, so this project will provide the fundamental proof of concept before moving to full-scale demonstration. The objectives of this project are to:
- Document the technical and economic feasibility of using reinforced 3D printable Ultra-High-Performance Concrete (UHPC) for the on-site manufacturing of high wind turbine towers,
- Develop a mix recipe for a printable ultra-high-performance concrete (UHPC)
- Develop two 3D printed tower concept designs that can be “Approved in principle” by an external verifier (DNV).
- Produce a 10-meter pilot "tower" to document the feasibility.
