The integration of the advanced wind power station and the novel high-pressure alkaline electrolyser makes it feasible to develop an efficient autonomous wind-hydrogen station (Figure 1). The station has estimated power of 200 kW, and, being operated at rated conditions, can produce 100 kg (1100 m3) of hydrogen per a day. It corresponds to...

Although the corrosivity may not be high provided the condensed moisture remains uncontaminated, this rarely happens in practice, and in marine environments sea salts are naturally present not only from direct spray but also as wind-borne particles. Moreover, many marine environments are also contaminated by industrial pollution owing to the proximity of factories, port installations, refineries, power stations and densely populated areas, and in the case of ships or offshore installation superstructures by the discharge from funnels, exhausts or flares. In these circumstances any moisture will also contain S, C and N compounds. In addition, solid pollutants such as soot and dust are likely to be deposited and these can cause increased attack either directly because of their corrosive nature, or by forming a layer on the surface of the metal which can absorb and retain moisture. The hygroscopic nature of the various dissolved salts and solid pollutants can also prolong the time that the surface remains moist.

Wind tunnel test methods were developed to determine wind induced stresses in cooling towers using aeroelastic models as part of a detailed model of a power station site. The turbulence and shear in the atmospheric wind are simulated. Tests on a model of Ferrybridge C Power Station show that resonant stresses are significant at the design wind speed. These increase as the fourth power of wind speed and can be greatly enhanced by turbulent wakes of upstream structures. 6 refs, cited. 

Wind Power Plant A group of wind turbines interconnected to a common utility system through a system of transformers, distribution lines and (usually) one substation. Operation, control and maintenance functions are often centralized through a network of computerized monitoring systems, supplemented by visual inspection. This is a term commonly used in the United States. In Europe, it is called a generating station.

On principle, renewable energies are without operational primary energy raw materials per se, their conversion technologies are one and all - such as the wind energy converter, the photovoltaic cell, the hydro turbine, the heat pump, the biomass converter, or the solar-thermal power station.
