By Jaap Bosch, head of business development, Ampyx Power Over the past decade, airborne wind energy systems (AWES) have made significant research and development advancements. Using tethered flying devices, including kites and planes, AWES convert wind energy into electricity and will soon be part of wind energy’s promise to be a dominant energy source. While…

By Hans Landin, group VP at Timken When it comes to the equipment inside wind turbines, performance and reliability can’t be compromised. Turbines are often in remote locations like mountaintops and offshore outposts. They must be built to withstand very harsh and dynamic operating conditions. They’re relentlessly pounded with weather extremes including oppressive heat, freezing cold,…

By J.L. Baker, CEO, GattiHR Many labor and workplace training concerns soon await the U.S. wind energy sector. In fact, several are unfolding right now. The industry currently employs about 7,000 wind-turbine technicians. That’s no doubt a hefty amount of labor. But according to industry reports, it’s not enough. Not even close. To meet the overwhelming…

By Gary Bills, Regional Director EMEA, K2 Management As the world edges toward a recovery from the COVID-19 pandemic, its demand and appetite remain unabated and continues to grow. The IEA projected that in 2022, there will be a 4% increase in global electricity demand. With gas prices at an all-time high and net-zero targets…

By Alex Baldassano, global head of energy transition, Climavision Energy transitions have been occurring globally since the 1800s. As demand patterns shifted and production technologies matured, the world witnessed an industrial revolution-fueled need for coal. This supply cornerstone gradually gave way to crude oil-based energy production in the early 1900s. Succumbing to the global oil…

By Thomas Dahlgren, President and CEO, COWI North America Commercial-scale floating offshore wind is approaching fast. In the United States, floating offshore wind is the only option on the West Coast and off the coast of Maine where the water depths preclude using bottom-fixed foundations. The Bureau of Ocean Energy Management (BOEM) has announced plans…

By Simon Alain, Senior Product Manager, Scanners and Inspection Solutions, Olympus In operation, a wind blade is subjected to considerable lift forces. To ensure the essential shear strength of the blade assembly, the top and bottom blade shells are bonded together, supported by a set of shear webs. The spar cap, the part of the…

By Mikko Nikkanen, Head of Maritime, Vaisala As wind energy continues to play an increasingly important role in future energy systems, developers are turning to offshore locations with inherently stronger, more consistent and more abundant winds to maximize the value of their projects. Just last year, investment in offshore wind surpassed $300 billion, according to…

By Sam Salem and Peter Nyegaard Jensen, Wind Cluster; and Fabio Orlandi, TER Rotary limit switches are used in wind turbines for managing and controlling the position of the nacelle (yaw control) and in some cases for pitch angle of the blades (pitch control). Whenever the direction of the wind changes, the wind turbine nacelle will…

By Jordan Freed, Director of Corporate Marketing & Product Strategy, Gastops There is an abundance of literature dating back over the past 20+ years about the challenge of premature gearbox failures, and the cost impact they have on wind turbine operation. While the principals of prognostics and health management (PHM) are well established, and the…

By Mark Goalen, director of offshore engineering, Houlder With offshore floating wind as a proven commercial reality, the challenges associated with the industry are now focused on delivering at scale, but there are still key innovation issues to be resolved across the industry. Meeting targets The global floating offshore wind industry is expected to reach…

By James Moorman, VP of sales, Helukabel USA The wind industry wrapped up another banner year in 2020 by commissioning 16,913 MW overall as an industry. With over 60,000 wind turbines in operation across 41 states, OEMs, asset owners and independent service providers follow industry technology advancements to maximize the efficiencies of new turbines and…

By Robert Speht, CEO and co-founder of FloatWind Ltd The world’s first gigawatt-capacity floating offshore wind farm remains a little way off, but advances across the industry are bringing it ever closer. As it stands, floating offshore wind farms have a levelized cost of energy (LCOE) of more than three-times that of fixed-bottom wind farms. And…

By Jonah Ury, senior associate; and Dan Kyle-Spearman, associate director; The Renewables Consulting Group Offshore wind has seen a remarkable cost reduction and growth over the last 30 years since the commissioning of Orsted’s 4.95-MW Vindeby Offshore Wind Farm, the first offshore wind project. Floating offshore wind, the next evolution of offshore wind technology, consists…

By Marcel Schreiner, Global Segment Director, Freudenberg Sealing Technologies’ Energy Sector The offshore wind energy industry is on the cusp of a significant transformation, fueled by increased demand for clean energy sources, technological advances and improved efficiencies. Based on projects currently under construction, annual installations of offshore wind turbines are predicted to grow from 6…

The potential for unlimited generation of clean, renewable energy makes offshore wind turbines a modern choice for global power production. While there are many benefits to offshore wind turbines, building them at sea poses some unique challenges during the transport and construction process. Construction at sea is a demanding task, and transporting the immense components…

By Martin Sørensen, director of alliances, WindESCo As the wind industry continues to scale-up globally, now is the time to reimagine how key players within the sector interact with each other, learning lessons from industries such as rotorcraft — where the correct functioning of complex gearboxes and rotating blades is a matter of life and…

By Bronwyn Sutton, Offshore Wind Principal; and Kim Connolly, Principal Engineer; Clir Renewables As the world increases investment in the energy transition, companies in the sector are expanding from small teams of tens or hundreds to multinational offices with thousands of employees. However, unless these companies take an active role in promoting diversity and equity…

By Shubhamita Basu, Ph.D., North America Product Manager, Industrial Oils; Carlos Nazario, North America Product Manager, Grease Additives; and Gareth Fish, Ph.D., Technical Fellow, Industrial Additives and Greases; Lubrizol Wind energy has steadily become one of the strongest components of electricity generation in the United States over the past 30 years.
