Leading Norwegian aluminium and energy company Hydro and World Wide Wind AS, a Norwegian company developing a floating wind turbine, have signed a Letter of Intent to explore the use of aluminium in the renewable wind industry. The two Norwegian companies are partnering up to develop floating wind turbines with a design specifically meant for offshore conditions. The goal is to use sustainable and recyclable materials in the construction, including aluminium.The collaboration comprises the following elements:Detailing of turbine design including the use of aluminiumProduction of prototypesBuilding a consortium of industrial partnersToday, wind turbines used for offshore floating wind have more or less the same design as turbines meant for land-based wind. In effect we are moving a land-based technology offshore. In World Wide Wind we are developing a new type of floating wind turbine for deep waters, with significant benefits relative to current technology in terms of energy production, cost, scalability, and environmental footprint. The new design gives us an opportunity to use aluminium components in parts of the wind turbine structure.World Wide Wind AS is a newly established Norwegian company presenting a novel solutions and technology – counter-rotating vertical axis turbines – which represent significant improvements over current VAWT technology. World Wide Wind’s CRVT solution mitigates some of the shortcomings of the current VAWT technology and is expected to surpass the current HAWT performance along most if not all parameters. World Wide Wind’s scalable design and technology for counter rotating vertical wind turbines represents the core elements of future wind turbine design, and will significantly improve the viability of wind power going forward.
