A sample calculation shows how this allows hydropower plants to more efficiently generate energy: thanks to Klüber Lubrication’s lubrication oil, a classic hydropower plant with a rated output of 50 megawatts (MW) can produce 92,000 kilowatt-hours more electricity per year using the same amount of water. This is enough to keep 30 three-person households supplied with power for an entire year: without any costly reconfiguration or expansion of the plant, and solely by choosing the optimal lubricant.
Simply put: Klüber Lubrication’s solutions aren’t just indispensable when it come to harvesting “green energy” from water; they also make it possible to do so particularly efficiently and sustainably. When it comes to hydropower applications, lubricants with a functional water component represent the pinnacle of environmental friendliness. Water has an especially low coefficient of friction, which can be used to reduce the machines’ energy consumption and extend service intervals.
“Hydroelectric power plants are a business that, especially given the increasingly stringent requirements for sustainability and environmental protection, we believe has a great future,” says Held. Viewed globally, hydropower plants are already the number one option for generating electrical energy from renewable sources. China, Brazil, Canada, the USA, and Russia are among the top countries in terms of installed capacity, while Norway’s electrical energy production is almost entirely based on hydropower. In addition, pumped storage plants and reservoirs can be used to store surplus solar and wind energy and rapidly convert it back into electricity as needed – e.g. when thousands of electric vehicles simultaneously charge their batteries on a night with little wind.
