Although significant investments have been made in recent years in offshore wind technology, the US offshore wind market is an untapped opportunity having the benefits of a strong wind resource and close proximity to major population centers along the US coast. However, the primary obstacle has been higher costs for offshore wind energy versus land-based installations. Early offshore installations are being planned for shallow water locations where project costs and risks are lower; however, the US has significant potential in deep-water locations that require floating systems. Bringing significant offshore wind energy into the mix, of course, requires that the cost of electricity generated from offshore wind turbines be competitive in the marketplace. And, deep-water solutions will be very important for the US.
This presentation will provide an overview of several offshore wind energy R&D projects at Sandia National Laboratories (USA) that are addressing unique conditions of the US offshore environment. These project snapshots will cover large-scale hurricane resilient wind turbine blade designs, novel floating vertical axis wind turbines for deep-water siting, offshore wind farm code development, and structural health monitoring & prognostics management systems.

Wind energy is playing a crucial role in providing clean, renewable energy for the expanding needs of the US electricity market. The US Department of Energy’s Wind Energy Technologies Office has developed a scenario, as part of the recent Wind Vision study report
, for wind energy to provide 10% of the nation’s electricity by 2020, 20% by 2030, and 35% by 2050. In 2016, 5.5% of US electricity was generated from wind energy. Offshore wind will play a major role in reaching out-year Wind Vision targets.
