HTS wire enables electric motors and generators to operate at higher power densities. When stacked up against a comparable copper wire based electric machine, future superconducting motors and generators could potentially offer a 2-3x size reduction with higher efficiency. A potential sweet-spot for high-powered HTS generators could very well be large, megawatt class offshore wind turbines. Offshore superconducting wind turbines promise to capture clean energy at a lower cost than competing renewables, while delivering power directly to growing coastal cities. They play a unique role offshore where conventional technology cannot achieve the “power per tower” requirement to make economic sense. Although initial costs for large offshore turbines are more expensive, such as in foundations and mechanical structures, these costs are recouped by higher energy yields. The increase in power density provided by superconducting turbines significantly reduces generator weight and maximizes power per tower, turning wind power into an economically viable alternative. |
