Wind Turbine Lubrication Challenges
Energy in the U.S. has surpassed 120 GW of installed capacity and continues to be a leading source of new generation additions. In 2020, wind power contributed the most energy compared to all other sources (solar, natural gas, etc.) at 18.5 GW. However, wind turbines are commonly plagued by reliability issues, including drivetrain components that experience unusually short lives. This is due to numerous reasons, many of which stem from lubrication issues. The replacement of these components comes at a very high cost due to these turbines' location and size. Furthermore, the industry is progressing to larger turbines, increasing power ranges from 0.75- 2.5 MW to 4-10 MW capacity, as well as moving turbine locations offshore, where access to the turbines becomes more costly, and environmental concerns of possible lubricant leakages arise.

Presenters Bio: Dr. Selim Erhan
Selim Erhan has a Ph.D. in Organic-Polymer Chemistry from Western Michigan University. After College he started as a research scientist at the National Center for Agricultural Research Service of the U.S, Department of Agriculture, on finding industrial applications for vegetable oils in areas such as rubber, paper, agricultural sprays, pharmaceuticals, food, lubricant, and oil field applications. Later he moved into industry and worked as a research scientist formulating lubricants at D. A. Stuart Company, Georgia Pacific, Polartech, Afton, Elevance Renewable Sciences and worked on finished metalworking formulations, additive packages for metalworking fluids, oil field drilling products, cleaners, and lubricant formulations. Following market development for vegetable oils as the Global Commercial Development Manager for Industrial Oils at Archer Daniels Midland Company. Currently Selim is the Director of Business Development, focusing on using the advantages of vegetable oils and derivatives in industrial applications at Process Oils Inc, an Ergon company.
Presenters Bio: Dr. Aaron Greco
Dr. Aaron Greco is the manager of the Materials for Harsh Conditions Group at Argonne National Laboratory where he leads a team of scientists and engineers on research related to investigation of drivetrain failure mechanisms, advanced materials and manufacturing technology, development of advanced coatings and investigation of the fundamentals of materials tribology. Prior to this Greco held positions at the U.S. Department of Energy Wind Energy Technology Office and The National Academies as a science policy fellow. Greco has more than 14 years of experience in the field of tribology, specifically in the areas of contact failure analysis, surface engineering and nanoparticle lubricant additives. Greco has been involved with STLE since 2004 and has served on the Tribology Frontiers Conference’s Planning and Awards Committees. He has been an STLE Annual Meeting technical session chair and associate editor of Tribology Transactions. He has received STLE honors for publishing excellence and poster presentations, a scholarship from the STLE Chicago Section and the ASME Burt L. Newkirk Award. Greco received his bachelor’s of science degree from Iowa State University and doctorate degree from Northwestern University, both in mechanical engineering.
