In the lifespan of a wind turbine, the gearbox is replaced on average four times due to wear and tear. All together this is almost the cost of a new turbine.
In June 2011, a hitherto unparalleled demonstra- tion of wind lidar performance was obtained in the calibrated wind tunnel belonging to LM Wind Power, Kolding Denmark:
The objective is to improve the design basis for large wind turbines by measuring wind and turbulence profiles at high altitude above a flat ground using modern instruments. The project will study
The research has resulted in new PEM-membranes structures both with and without fluor with a wider temperature window and good mechanical strength. The PEM may be used in both hydrogen- and direct
The vision is that the increased research on main wind turbine uncertainties and risk & reliability will lead to less conservative designs and more cost-efficient wind energy. Therefore, careful
The usage of new reinforcement fibre and resin systems allows for novel forms of blade design, cost optimisation and production methods that significantly reduces the production time.
The HyLIFT-C3 project develops and commercial- ises hydrogen propelled fuel cell hybrid systems for pollution free and time efficient propulsion of forklifts for warehouses and distribution centres.
Employing a porous metal structure enhances the robustness of new high temperature fuel cells. Stack modules are being developed with these novel cells, initially for applications such as truck APUs.
The project develops proton-conducting and mixed proton-electron conducting materials stable in atmospheres containing CO2. The materials will be used in future energy-efficient and environmentally
The objective of the project was to improve the durability of the membrane electrode assemblies of PEM fuel cells by studying the basic degradation phenomena of carbon supported Pt catalysts and
The EU's and the Danish government's goal of replacing major parts of fossil fuels with sustainable energy sources requires new processes to be developed for conversion and storage of energy, for
Today, wind turbine control systems are designed separately from its structural, aerodynamic qualities, but to achieve cheaper, more reliable wind turbines, the design phases need to be united into
The project studied sediment bed conditions, scour/erosion, and quick-sand-like conditions that may occur due to the effects caused by wave and current action. Illustration from laboratory experiment
On a hot windy summer day, with beautiful clouds in the sky, the air is full of turbulence, like a hot pot of boiling water. In these unsteady surroundings a bird of prey is hovering, completely still
SERC was carried out during the period from primo 2007 until end of 2012 I cooperation with leading Danish and International research institutes plus a wide spectrum of industrial partners. The
The aim of the HYSCENE project is to improve our understanding of the environmental impacts and related socio-cultural and welfare economic impacts of a renewable energy system where hydrogen is an
Design and planning of wind turbines involves considerable uncertainties related to estimating the energy production and to assessment of loads and load carrying capacities.
The project aimed at studying the effect of inflow turbulence in blade calculations by using CFD and with several Delayed Detached-Eddy simulations (DDES) for blade profiles, both profiles in free
