On-site 3D Concrete Printing for Next-Generation Low-Cost Wind Plants
Advancing on-site 3D concrete printed turbine towers to enable tall wind development.
Projects Updates/The Results
The kick-off meeting was conducted in June 2020. The team conducted some preliminary activities, such as reviewing 3D concrete printing (3DCP) materials and techniques for tower design, developing conceptual design drawings for a 3DCP segmented tower with various strategies for reinforcement, and initiating work on a finite element analysis.
This agreement aims to manufacture, demonstrate, and test wind tower sections and offshore wind energy components using an onsite three-dimensional concrete printed (3DCP) manufacturing process and design. The advancement in scientific knowledge in 3DCP materials, manufacturing methods and large-scale structural performance will facilitate the deployment of large land-based and offshore wind technologies that use 3DCP components to increase the cost-competitiveness of the wind energy generation needed to meet California's statutory energy goals.
The use of additive 3D manufacturing approaches facilitate the development of taller wind turbines that significantly reduce the number of wind turbines deployed on a site for a given wind plant capacity, resulting in more aesthe
This additive concrete 3D manufacturing technology targets are to manufacture a hybrid 140-m wind turbine tower on-site, at half the cost of conventional steel 140-m towers for a 7.5 MW next generation turbine.
Increasing the tower height from 80 m to 140 m increases the potential wind capacity in California, which may be suitable for development more than 10 times (from 6 GW to 67 GW), representing about $60 billion of potential wind p

Wind deployments avoid substantial emissions of greenhouse gases compared to fossil fuel generated electricity. Wind generated electricity emits up to 120 times less carbon dioxide (CO2e) than natural gas generated electricity an
As California moves toward a zero-carbon electricity mix in 2045, land-based and offshore wind can provide value to the grid by balancing solar generation. A 140-m RCAM tower will increase California land areas with gross capacit
