The renewable energy sector is growing at an exponential rate in the UK and internationally. Central to this growth is a range of modern fluid power systems, which are especially pivotal in hydroelectric and wind energy applications. In this article, we’ll explore the role of hydraulic and pneumatic applications in renewable energy and how your project can benefit.
Hydroelectric Power
In hydroelectric power, for example, hydraulic and pneumatic applications manage the flow of water through dam gates and control turbines, helping to convert hydraulic energy into mechanical energy for power generation. Precision controls are essential for managing the volume of water released to the turbines – which are responsible for converting the kinetic energy of flowing water into usable energy. The mechanical energy can then be transformed into electricity by generators. The power density provided by fluid power systems make them ideal for efficiently managing these processes, delivering maximum energy output and minimising waste. Fluid power systems are generally straightforward and robust, with fewer points of failure than many purely electric actuators and mechanical systems. This gives them the ability to function reliably and accurately in the harsh marine environments characteristic of hydroelectric locations. Many components, for example, have a high tolerance to corrosion, temperature fluctuations, high humidity, and salt water exposure.
Wind Energy
Meanwhile, in onshore and offshore wind farms, fluid power systems are utilised to adjust the pitch of turbine blades and provide efficient braking mechanisms, optimising energy capture and improving operational safety. This helps to maximise the amount of energy captured, and sustains turbine efficiency under varying wind conditions, as well as making sure that the turbines can be safely stopped during high winds or maintenance operations.
Innovations And Developments
The intersection of fluid power and renewable energy is a two-way exchange. The demands of modern renewable infrastructure have also driven important innovations in many hydraulic systems, including the integration of smart technologies that allow better real-time monitoring and predictive maintenance. This is crucial in offshore and remote renewable energy sites, allowing engineers to oversee day-to-day operations without being physically present, and reducing the risk of unexpected structural failures.
Improvements in the materials used in hydraulic components, and also the hydraulic fluids themselves, have also increased the practicality and durability of these proponents for renewable energy applications, making them more reliable and sustainable.
The partial electrification of hydraulic systems is another noteworthy development in the renewables sector. By replacing traditional hydraulic actuators with electric ones, for example, energy losses from fluid compressibility and resistance could be minimised. This transition to fully electric or hybrid systems can boost system efficiency and mitigate the environmental risks linked to some hydraulic fluids – making operations safer and cleaner.
