Innovative Rotor Blades to Drive Wind Turbine Components Market Worldwide

Published Date : Jun 02, 2016

The growing concern for the environment is one of the primary factors driving the growth of the global wind turbine components market. Combustion of fossil fuels for power generation leads to emission of carbon dioxide which, in turn, contributes to global warming. Presently, the energy sector accounts for about 40% of overall carbon dioxide emissions. Hence, a number of countries are encouraging the usage of renewable energy sources for power generation. Wind power generation offers a number of benefits such as low air pollution and no water consumption. Wind energy is also the cheapest source of power generation.

Wind energy is gaining priority over fossil fuels in the power mix of both developed and developing nations as it is capable of addressing power requirements of nations in an environmentally sustainable way. Some of the key wind turbine components are rotor blade, tower, generator, gear box, and others. Rotor blade is the most expensive component in a wind turbine as it directly affects the efficiency of the turbine. The tower of a wind turbine is crucial in determining additional power production. The turbine tower designs have witnessed various technological advancements on the basis of size and type such as concrete, tubular, lattice, and guyed pole.
Polyurethane Rotor Blade for Wind Turbines in Asia

At the Shanghai FRP Research Institute, a 37.5 meter long rotor blade for wind turbine has been developed utilizing a special polyurethane infusion resin and glass fiber mats. In harnessing wind power, polyurethanes are economically viable in terms of cost and performance over epoxy resins. Polyurethanes are environmentally sustainable too as less thermal energy is released during the processing of polyurethanes. The polyurethane rotor blade has been developed with a special infusion resin manufactured by Covestro while glass fiber mats have been supplied by Chine-based CPIC.
