The Siemens GAMA Renewable Energy Group has been researching and developing the concept of energy storage as a heat sink combined with wind energy. This week, the company has started building its first real-scale project in Hamburg, Germany.

The company said it is building the first comprehensive "Future Energy System - FES" at the Trimet SE aluminum smelter in Hamburg, Germany. As a combined form of Siemens wind power and renewable energy sector, the company has been devoted to the research and development of thermal energy storage, especially by heating rockfill to store wind energy.

According to reports, FES will supply about 1,000 tons of rock fill, which is heated and can then power a steam turbine at 600 degrees Celsius to provide 30 megawatt hours (MWh) of electricity. The steam turbine can then convert the heat back into electricity.

A 1.5 MW rated generator will generate up to 24 hours of electricity, enough to meet the electricity needs of 1,500 average German homes or to charge up to 50 electric vehicles. Energy storage technologies are crucial to ensuring that variable sources of energy, such as wind energy, provide electricity to the grid at all times. However, Symantec said that some storage technologies have limited capacity, unlike other storage technologies that are cost-competitive.

That is why, with support from the German Federal Ministry of Economic Affairs and Energy, Siemens GMA has been studying FES technology for a long time. The company believes that the technology provides a highly economical way to store energy.
