Abstract

The cost of energy generated by large scale vertical axis wind turbines faces great chal-lenges for it to be competitive with conventional horizontal axis wind turbines for offshore deploy-ment. To become competitive significant reductions in capital cost and operational costs would be require. A novel vertical-axis wind turbine, that aims to meet these requirements is proposed, the X-rotor wind turbine. An early-stage feasibility study of exemplary two and three-bladed 5MW tur-bines are reported. The cost savings arising from two aspects of the concept that have the greatest impact, namely the power take-off system and O&M, are quantified. Two other aspects that could have a major impact on the cost of energy are the vertical axis rotor and the jacket. The masses for both are evaluated proxies for their costs. The former costs are determined to be substantial relative to those of conventional HAWTs. Whereas, the latter masses are determined not to be prohibitively greater relative to conventional HAWTs.
