X-ROTOR is a research project under the EU Horizon 2020 programme, which is working to develop a disruptive new offshore wind turbine concept. 

X-ROTOR will develop a highly innovative wind turbine design to directly target cost of energy reduction and scalability of wind turbines.The project aims to take X-ROTOR concept from its current technology readiness level of TRL 1 to TRL 3. In doing so, the goal is to determine the X-ROTOR’s economic, social and environmental impacts and confirm the potential for a levelised costs of energy (LCOE) reduction of 20-30%. In realising this overarching objective the project has three subsidiary objectives,

1. To determine the performance of the X-Rotor concept by designing the mechanical structure, operational strategy, and carrying out a performance assessment.
2. To design a power take-off and conversion system, which provides full freedom of choice of operating strategy.
3. To estimate the reduction in levelised cost of energy (LCOE) including both the CAPEX and OPEX
   components.
