Large-scale offshore wind energy developments represent a major player in the energy transition but are likely to have (negative or positive) impacts on marine biodiversity. Wind turbine foundations and sour protection often replace soft sediment with hard substrates, creating artificial reefs for sessile dwellers. Offshore wind farm (OWF)...

Offshore wind energy (OWE) is a cornerstone of future clean energy development. Yet, research into global OWE material demand has generally been limited to few materials and/or low technological resolution. In this study, we assess the primary raw material demand and secondary material supply of global OWE. It includes a wide assortment of...

Continuous reduction in the levelized cost of energy is driving the rapid development of offshore wind energy (OWE). It is thus important to evaluate, from an environmental perspective, the implications of expanding OWE capacity on a global scale. Nevertheless, this assessment must take into account various scenarios for the growth of different...

The concept of wake steering on wind farms for power maximization has gained significant popularity over the last decade. Recent field trials described in the literature not only demonstrate the real potential of wake steering on commercial wind farms but also show that wake steering does not yet consistently lead to an increase in energy...

Rain-induced leading-edge erosion (LEE) of wind turbine blades (WTBs) is associated with high repair and maintenance costs. The effects of LEE can be triggered in less than 1 to 2 years for some wind turbine sites, whereas it may take several years for others. In addition, the growth of erosion may also differ for different blades and turbines...

In this chapter the derivation of the viscous integral boundary layer equations is presented in an unsteady, two-dimensional form. Closure sets for both laminar and turbulent flow conditions together with a laminar to turbulent transition method are given. The solution methods for the inviscid region and the viscous-inviscid interaction coupling...

Wind generation on the North Sea is rapidly expanding. Offshore wind generation is expected to be a major source of energy for the future carbon-free energy system. The onset of this rapid growth is already visible. In the IJmuiden Ver area, 80 kilometres off the coast at Den Helder, a wind park expansion of 4 GW is planned by 2030, and possibly...

Data on the potential generation of energy from wind, solar and biomass is crucial for analysing their development, as it sets the limits on how much additional capacity it is feasible to install. This paper presents the methodologies used for the development of ENSPRESO, ENergy System Potentials for Renewable Energy SOurces, an EU-28 wide, open...

Offshore wind turbine rotor diameters still increase. Blade tip velocities are up to 110 m/s, giving rise to more severe raindrop impact conditions and related erosion of the wind turbine blades. In the current work droplet impingement erosion tests were performed for injection moulded and compression moulded polybutylene terephthalate PBT. The...

Numerical results for the 4.5 meter diameter wind tunnel tested Mexico rotor have been successfully established with two in-house CFD solvers (SU2 and OpenFoam) using a constant but relatively coarse grid. Still the simulations heavily suffered from limited computation power, in particular for SU2 which could not be parallelised efficiently and...

Erosion of the leading edge of wind turbine blades by droplet impingement wear, reduces blade aerodynamic efficiency and power output. Eventually, it compromises the integrity of blade surfaces. Elastomeric coatings are currently used for erosion resistance, yet the life of such coatings cannot be predicted accurately. This review paper gives an...

Electricity generation on offshore wind parks has an increasing economic importance - the European Commission foresees that 12% of the wind energy will be produced on offshore installations by 2020, and this share is likely to increase further in the following years. However, the continuously varying offshore environment and the interaction...

Since the opening of the Dutch retail market for renewable electricityin July 2001 the number of renewable electricity customers has increased from about 250,000 to approximately 1.4 mil-lion in January 2003. This surge in the demand for renewable electricity was caused mainly by favourable fiscal incentives for renewable electricity production...

A computer model that calculates the transport and installation costsof a wind farm has been composed and implemented in the OWECOP II model of ECN. The latter quantifies all costs of implementation of a wind farm, at a determined location on the Dutch Exclusive Economical Zone. Transport and installation are a part of it. The computer model is...
