Wind and Solar


Wind power

The use of wind energy dates back about two thousand years, when very simple wind power installations evolved over the next few centuries into the first horizontal-axis wind turbines.

However, at the end of the 18th century, another form of energy was harnessed that changed our lives forever - electricity. Therefore, windmills were redesigned as wind generators, the mechanism by which wind energy is converted into electricity.

Fast forward to the 21st century, and modern wind turbines consist of three basic elements:

Base and Tower - for positioning and supporting the wind turbine
Nacelle - houses the yaw system, drive train and electrical cabinet
Rotor - contains rotor hub and blades

Key considerations for onshore wind vs. offshore wind

• Pedestal technology
Onshore wind farm foundations rely on concrete conical bases, anchored into the ground by multiple piles. Offshore wind power foundations use fixed bottom foundations, such as monopile systems for water depths up to 30 meters and jackets for 50 meters. Above this depth, a floating base is used, which allows great flexibility in positioning the fan.
• Installation technology
Onshore construction sites can use standard lifting equipment, and delivery cables can be routed to users. Offshore installation projects are costly due to offshore weather conditions and the need for long cables, offshore cranes, and specialized vessels.
• Fan capacity
Onshore wind turbines are typically limited to 5 MW, while offshore wind turbines are capable of rated power of 14 MW. Because cost is not linear with rated power, large wind turbines typically generate electricity at a lower cost.
• capacity factor
Offshore wind turbines have higher capacity factors. An example of using this factor – actual generation versus theoretical maximum – is the EU capacity factor for 2019, with 24% for onshore wind and 38% for offshore wind.

Case study
A manager of a "wind farm" had contacted Mitsubishi Chemical Advanced Materials for assistance troubleshooting performance and maintenance issues. Due to weather, temperature and mechanical loads, the bearing surfaces of the positioning systems of each unit quickly failed, which also resulted in extreme noise. These failures could force maintenance crews to climb up 80-meter ladders to lubricate the unit's stuck bearings, whether it's night, freezing cold or scorching heat. Loss of capacity and emergency maintenance costs due to unit damage is a major expense.

Solution
Ketron® PEEK HPV products from Mitsubishi Chemical Advanced Materials are the designated solution. It offers an ideal combination of lubricity, load carrying capacity, low coefficient of friction and noise rejection.

In individual cases, Ertalyte® TX or Nylatron® 703 XL can also be used.
