Long-term variability: Historical records of sea level pressure in Europe extend back to the 1870s. These were used to calculate the geostrophic wind speed. This was analysed for the offshore waters of Europe with respect to long-term trend. Medium-term variability: Using a da...

[REPORT SUMMARY] Seasonal and annual predicted wind speeds for offshore Europe at heights between 10 and 150 m
Mean wind conditions for the period 1985-97 were estimated using WAsP at eight hub heights at each POWER grid point over the sea. The hub height levels (10m, 30m, 50m, 70m, 90m, 110m, 130m and 150m above mean sea level respectively) were chosen to cover the range of expected h...

[REPORT SUMMARY] Methodology to compute confidence limits for POWER wind speeds
A bootstrapping estimation method was used to gauge the reliability of the POWER wind speed estimates by calculating 95% confidence limits in the mean monthly wind speed estimates. Bootstrapping uses the available data to create a many additional data sets using re-sampling wi...

[REPORT SUMMARY] Dataset of annual, seasonal and monthly mean geostrophic wind speeds over EU waters at resolution of 0.5o latitude by 0.5o longitude
Geostrophic winds are theoretical winds that flow parallel to isobars (contours of equal pressure). They are a good approximation to the actual wind in the free atmosphere. They can be calculated from atmospheric pressure data. This is significant because while measured wind d...

[REPORT SUMMARY] An improved measure-correlate predict algorithm for the prediction of the long term wind climate in regions of complex environment (NNMCP)
A MCP (measure-correlate-predict) algorithm has been developed to predict the long-term wind resource of a site (and thereby the production of a planned wind farm) based on a neureal network model. Very difficult to predict in complex terrain, so any improved algorithms will e...

[REPORT SUMMARY] Verification of European windturbine design codes
The European wind industry uses wind turbine analysis codes for the calculation of dynamic loads and energy yield. The codes are based on detailed aeroelastic and structural models. A stochastic wind simulator is part of the code: It provides the turbulent wind over the rotor ...

[REPORT SUMMARY] Hydrogen-rich gas from biomass steam gasification
The aim of this project was the development of a fluidised bed gasification process for the production of a hydrogen rich gas from biomass.
To achieve this aim, a 500kWth pilot plant was build and tested, a catalyst for fluidised beds was developed and fundamental research on...
