The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is reduced levelized cost of electricity (LCOE) of offshore wind from current levels that are about twice that of onshore wind. Given the proximity of offshore wind resources to load centers along the coast, it is an attractive renewable energy source for the nation, but high costs are an impediment to widespread adoption. One way to address this is with larger turbines that can lead to lower ?balance of plant? costs, which can be as high as 65% of the total project costs of offshore wind. However, turbine rating is currently limited due to the large size and weight of the generator and the rotor, as well as infrastructure obstacles like manufacturing, transport, and assembly. The lightweight superconducting (SC) generators being developed within this project, coupled with advanced rotors already being developed by the OEM?s, could open the door to significantly larger turbine ratings and lower costs. The underlying high specific power machine technology can also help transform a number of other weight-sensitive electrical systems like hybrid electric airplanes and ship propulsion. This Small Business Innovation Research (SBIR) Phase I project seeks to disrupt the traditional risk versus benefit trade of the low Technology Readiness Level (TRL) SC technology by significantly increasing the benefits with a novel ?active magnetic shielding? concept. This design concept enables a very high operating magnetic field within the machine while eliminating the need for a yoke made of ferromagnetic steel to contain the field. The higher internal fields increase the electromagnetic torque significantly over other solutions, leading to very high power density. Additionally, the elimination of heavy iron from the magnetic circuit leads to further reduction in weight. The proposed generator design can be about half the size of currently available wind direct-drives. Efficiency is also expected to improve with the elimination of about a third of copper coils while maintaining the same current density. Available cryogenic cooling technology from the commercially successful magnetic resonance imaging (MRI) industry will be adapted and utilized in the machine to reduce many of the cryogenics related risks while maintaining high specific power.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I期项目的更广泛的影响/商业潜力降低了电流的电力成本（LCOE），其目前的水平约为陆上风的两倍。鉴于海上风力资源沿着沿海地区装载中心的距离，这是该国有吸引力的可再生能源，但高昂的成本是广泛采用的障碍。解决此问题的一种方法是，较大的涡轮机可以导致植物平衡较低？成本可能高达近海风能的总项目成本的65％。但是，由于发电机和转子的大尺寸和重量以及制造，运输和组装等基础设施障碍，目前涡轮机的评级目前受到限制。在该项目中开发的轻量级超导（SC）发电机，再加上OEM已经开发的高级转子，可以打开大门，以明显更大的涡轮机评级和更低的成本。基础高特异性电动机技术还可以帮助改变许多其他对重量敏感的电气系统，例如混合电动飞机和船舶推进。这项小型企业创新研究（SBIR）I阶段项目试图通过通过新颖的“主动磁性屏蔽”来显着提高收益，以破坏低技术准备水平（TRL）SC技术的传统风险与利益贸易？概念。该设计概念使机器内的操作磁场非常高，同时消除了对铁磁钢制成的轭的需求，才能包含该磁场。较高的内部场比其他溶液显着增加电磁扭矩，从而导致功率密度很高。另外，从磁路中消除重铁导致重量进一步减少。所提出的发电机设计可能是当前可用的风向驱动器的一半。预计效率也有望通过消除大约三分之一的铜管，同时保持相同的电流密度，从而提高效率。从商业上成功的磁共振成像（MRI）行业中可用的低温冷却技术将在机器中进行调整和利用，以减少许多相关的风险，同时保持高特异性的功能。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力功能和广泛的影响来评估CRETERIA的评估，这是值得通过评估的支持。
