Spanish renewable energy giant and offshore wind leader Siemens Gamesa Renewable Energy announced last week that its Altenwerder, an electric thermal energy storage system capable of storing up to 130 megawatt-hours of electricity
in volcanic rock, was officially launched.
Siemens Gamesa, a company known for its offshore wind turbines, is also a large manufacturer of renewable energy technologies with a variety of renewable technologies, including energy storage
.
Last week, the company announced the start of operations for its electric thermal energy storage system (ETES), calling it a "world first.
"
The electric thermal energy storage system put into operation is called "the energy solution of the future" by Siemens Gamesa and is much
cheaper than traditional energy storage solutions.
According to the company, even at the gigawatt-hour (GWh) pilot scale, ETES "is highly competitive
compared to other available storage technologies.
" ”
The thermal storage facility includes about 1,000 tons of volcanic rock, which is used as a storage medium
.
The rock is fed with electricity, which is then converted into hot air by resistance heaters and fans, which then heat the rock to 750°C/1382°F
.
When demand requires stored energy, ETES uses steam turbines to re-electrify the stored energy and feed it back into the grid
.
The new ETES plant can store up to 130 MWh of thermal energy for a week, and the storage capacity remains constant
throughout the charging cycle.
"With the commissioning of our ETES pilot plant, we have reached an important milestone on the road to introducing a high-performance energy storage system," said Markus Tacke, CEO of Siemens Gamesa Renewable Energy.
