Technology Description:

The proposed technology will boost the power production and increase the density of utility wind farms, resulting in at least a 23% reduction in levelized cost of energy (LCOE) from the wind. The flow dynamics of vertical-axis wind turbines (VAWTs) enable constructive interactions between rotors in a wind farm, increasing power up to 30% over non-interacting turbines, and increasing VAWT density per unit land-area an order of magnitude compared with state-of-the-art wind farms. XFlow Energy Company (XFlow) will perform simulations to examine the impacts of close turbine spacing on rotor fatigue and power performance coupled with experimental studies to validate and refine the simulation models.
