Pumped Hydro Storage

Large energy storage facilities are an essential ingredient of future renewable energy systems to filter out unpredictable supply of renewable energy. Here a few videos about pumped hydro storage systems.

Norway derives almost 100 percent of its energy from hydropower. For Germany’s planned transition to renewable energy, a close partnership is crucially important, because Norwegian pumped storage power stations could balance out variations in renewable energy sources. But do Norwegians actually want to their country to become Europe’s storage battery?

HRH the Prince of Asturias and IBERDROLA Chairman, Ignacio Galán inaugurated Europe’s largest pumped-storage hydroelectric scheme at Cortes-La Muela in the Júcar river basin, in the municipality of Cortes de Pallás (Valencia, Spain).

Storing renewable energy has always been a challenge but UNSW water engineers have refined a solution involving existing hydroelectricity technology and dam infrastructures. Pumped storage requires two connected reservoirs. Water is pumped to an elevated reservoir using renewable energy and released during peak demand times, when those renewables are offline, to drive a turbine and rapidly generate hydroelectricity. Professor Bill Peirson, the Director of the UNSW Water Research Laboratory, believes that such a solution will enable the storage of significant reserves of renewable energy, provide resilience to the grid and will enable active use of flood mitigation infrastructure that would otherwise sit idle between major flooding events.

Setting a world record – How a pump-storage plant in the Alps is increasing energy efficiency

The Vianden hydro-electric power plant, situated in the Our Valley in Luxembourg, is one of the largest in Europe. The Vianden pumped storage hydroelectricity plant, which was built between 1959 and 1964, is connected to the German grid and represents an important link in the Western European network. Electricity demands undergo rapid and important fluctuations during the day. Pumped storage hydroelectricity is a method of storing and producing electricity to supply high peak demands by moving water between reservoirs at different elevations. Surplus energy available during off-peak hours is used to pump water from a lower reservoir to an elevated storage basin. This water is released during peak hours to produce high-value electricity. A total of ten hydroelectric units are installed to generate a total capacity of 1100MW. The infoclip includes: – Various shots of the Our Valley; – Exterior and interior shots of the Vianden pumped storage hydroelectricity plant; – Dam; – Pylons.

Germany wants to massively expand the use of renewable energy. But that aim has its problems. When no wind blows and the sun isn’t shining, relying solely on renewable sources would mean power shortages. To prevent this, ways have to be found to store electricity. The most effective technology to date is pumped storage power plants.Report by Sonja Schock

TEDx Talk Hydraulic Hydro Storage

A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations.

– Potential for pumped hydro energy storage in Australia.
– Description of the technology.
– International models and project examples.
– Potential sites for pumped hydro plants in Australia.

Webinar Description- Pumped energy storage is being touted as a key technology for balancing the electrical grid with increased intermittent renewable energy development. It is important, however, for developers to have a basic understanding of what is involved in feasibility determination, licensing and engineering.
