FEATURE “Wind energy” g…/…Dual focus needed for wind energy real cost of nuclear energy, for example, with the unknown cost of long-term storage of waste? We expect growth in the near term to take place predominately in China, India and North America. There is a drastic need for power in China and wind is a good option there. It doesn’t add to their carbon footprint, which is already substantial, and it doesn’t require the infrastructure that other forms of energy require. India also has a growing appetite for energy. Denmark now gets an average of 20 percent of its annual energy needs from wind energy. On a windy day, the country is able to generate 100 percent of its energy needs with wind power. Process Improvements Wind project performance has gotten better in recent years and we fully expect this trend to continue. Incremental performance improvements have come through a variety of refinements ranging from improved project siting to advancements in wind turbine and blade technology. New proprietary gel coats have improved blade weathering and UV resistance. Blade profiles have been designed to maximize the potential of whatever wind is available. Fabrication facilities are being built near major wind corridors to minimize delivery costs. Vacuum infusion has become a popular process choice for wind blade fabrication. Infusion has several benefits compared to hand lay-up, both from an environmental and efficiency point of view. It is well-known that infusion reduces VOCs in the work environment. Also important is its ability to evenly wetout very large parts with the correct amount of resin, thus making blades that are less expensive and lighter, and thus better. Other fabricators are using prepregs to enhance material use and performance. And wind blades have become very large. When MFG got into the business they were making what they thought were huge blades – 8.2 and 9.1 meters. Today, most of the blades they make are more than four times that size and the trend to longer blades continues, especially for off-shore installations. The larger 5 megawatt turbines have blades that are 61.5 meters long. A high-performing wind turbine blade must not only have an aerodynamic design, it must also meet mechanical requirements such as rigidity, torsion resistance, and resistance to material fatigue. The end of the blade must not touch the pole, and this gap must be maintained over its 20-year lifespan. Transforming the Market Why bother with innovation, new technology and ideas that might increase material, turbine or installed costs when the market is sold out for the next two years? The answer can be found in the potential for market growth. The composites share of the wind energy market is greater than it is in any other form of energy production. But wind energy is currently only a small percentage of all energy used at less than 2 percent. And the industry is currently dependent on subsidies to be competitive. The potential for sustainable growth will be huge when wind energy is able to stand on its own and compete with other forms of energy head-to-head on cost. Wind turbine producers currently think in terms of providing machines at a certain cost; for example, a 2.5 megawatt machine at $3.5 million (±$1.4 million/MW). Most producers are not interested in anything that will increase cost and they are reluctant to embrace innovation. Operators are concerned about installed cost, of course, but they are also focused on operating efficiencies Finished wind blade wait their turn for delivery and cost per kilowatt of the electricity they generate. From their perspective, the question is not about lower installed cost but, “How can we drive the cost per kilowatt from seven cents to four-and-a-half cents?” Owens Corning is now working directly with the developers and operators of wind farms. We are looking at the situation from their perspective and asking ourselves and our partners how we can respond. We know the operators are interested in more efficient turbines that can generate more electricity with the same amount of wind. We know they are interested in turbines that require less maintenance. Turbines today also use gearboxes that require attention. The gearboxes and their bearings can fail and need to be replaced. And with blades getting larger and heavier and turning faster, the loads and stress on gearboxes and their bearings have increased. We are working with a partner to develop blades that are lighter and reduce the load on bearings and gearboxes. Owens Corning has also developed an affordable family of highstrength reinforcements. Trademarked WindStrand™, the products are made with a new high-performance reinforcements platform at a cost substantially lower than competitive materials. WindStrand reinforcement allow turbine manufacturers to increase blade length by as much as 6 percent and deliver up to 12 percent more power – for up to 20 percent less cost than competing carbonglass hybrid solutions currently on the market. Providing specialty performance at a more affordable cost allows design engineers to take full advantage of the potential benefits of larger blades. We are also working with companies that are developing direct-drive systems that do not require a gearbox. With 20 percent annual growth forecast for the foreseeable future, wind energy should continue to be an exciting and dynamic market for composites. The market has taken off in the past 10 years and the next 10 should be just as active. With our feet firmly planted in the reality of today’s challenges and our eyes looking to market transformation for the future, we could make wind energy the market that enhances perceptions of composites as an enabling material for the world of tomorrow.
