The U.S. Department of Energy (DOE) will offer $1.8 million in funding for the development of larger wind turbine blades. The money is meant to support R&D costs for manufacturing, transportation, and assembly of blades larger than 60 meters.
The main reason why the DOE wants to see technological innovations in wind turbine blade size is because there is an opportunity for larger wind turbines to harness more wind on an additional one million square miles of land in the United States. This amounts to something like triple the sites available for wind turbines made back in 2008.
According to the Funding Opportunity Exchange posting # DE-FOA-0001214:
The objectives of this FOA are to:
1. Reduce the levelized cost of energy (LCOE) of land-based wind power in appropriate wind regimes by enabling the use of taller towers over their entire lifecycle, allowing wind turbines to capture stronger wind resources aloft.
2. Increase the wind turbine deployment opportunities in lower wind speed regions across the country where wind energy has previously been more expensive to deploy.
3. Increase U.S. competitiveness in alignment with the EERE Clean Energy Manufacturing Initiative (CEMI).
This particular posting goes hand-in-hand with FOA #DE-FOA-0000982 which is all about increasing the hub height of large wind turbines:
This Funding Opportunity Announcement (FOA) will support the development of technologies that mitigate U.S. transportation and logistics constraints affecting the deployment of taller utility-scale wind turbine systems. Continued turbine up-scaling and design advancements are expected to increase turbine performance and lower costs. Scaling to higher hub heights allows wind turbines to capture less turbulent and often stronger wind resources, thereby improving productivity and economics.  Supported projects will develop lifecycle cost-competitive tower solutions that address the challenges of fabricating, transporting, assembling, maintaining, and decommissioning towers for turbine hub heights of at least 120 m.
The main reasons for offering funding of these advancements in wind are to increase the US competitiveness in manufacturing, reducing wind power costs, and expanding the available sites that wind turbines can be installed at in the US.
Let’s see if the Americans can top the SeaTitan wind turbine with a rated power of 10MW, a rotor diameter of 190m and hub height of 125m; currently the largest wind turbine in the world!
