The business prospect for small to medium-sized floating windmills equipped with storage batteries is quite promising, especially considering the current initiatives and investments in the field of floating offshore wind energy. The U.S. Department of Energy, along with other federal agencies, has dedicated over $950 million to support the development of floating offshore wind technologies, including research on high-voltage direct current and hydrogen co-generation feasibility. This investment indicates a strong commitment to advancing floating wind technology, which aligns well with your concept of mobile, towable windmills for areas with fluctuating electricity demands. Additionally, the success of projects like WindFloat Atlantic, which generated 80 gigawatt-hours of electricity, exceeding expectations even in extreme weather conditions, demonstrates the viability and resilience of floating wind turbines. Moreover, the integration of battery storage, as seen in the Batwind project, where 1 megawatt batteries store power from floating turbines, shows that the combination of wind energy and storage technology is not only feasible but also effective in managing supply according to demand. Government initiatives, successful precedents, and technological advancements in both floating wind energy and battery storage solutions support the prospect of such a business. It’s a forward-thinking idea that could meet the needs of a dynamic energy market.
