Denmark's LM Wind Power has kicked off a groundbreaking research project to develop a range of blades with cost-trimming flexible tips.
The four-year scheme, being
running by a consortium including the Dutch University of Twente and the Energy
Research Centre of the Netherlands, is targeting a cost of energy reduction of
8-10% from large-rotor blade designs featuring composite extensions of varying
"The cost of wind power,
especially offshore wind power, needs to go down to compete with other energy
sources and we are committed to making that happen,” says LM’s vice president
for engineering Roel Schuring.
“This project aims to help wind
farm developers and wind turbine manufacturers to design wind farms better and
to get the most from each turbine. This
will improve annual energy production and reduce cost of energy. The potential
The project, backed by the Dutch
Ministry of Economic Affairs, is working from the idea of existing lightweight
composite blade concepts with "one shot" fabricated tip add-ons as
a "permanent assembly of two blade parts".
Adding little extra weight, the extended
blade concept is expected to result in a larger rotor that boosts annual energy
production "significantly for a relatively small investment".
