The heat storage tank is 45m high and has a capacity of 56 million liters.It will store district heating water at 98 degrees Celsius and, according to Vattenfall, will use heat generated by renewable electricity from the grid.
Sweden-based energy company Vattenfall is currently building what is said to be the largest thermal storage tank in Europe.The facility, located at the 600 MW Reuter-West coal-fired power station in Berlin, is scheduled to come online in April 2023.
“We actually have an optimal fossil-fuel-free and future-proof way to provide heat to our Berlin customers,” the company said.”When excess wind energy is available, this surplus can be converted by on-site electricity-to-thermal power plants and then stored in a buffer.”
The plant is 45 m high and has a capacity of 56 million liters.It will store district heating water at 98 degrees Celsius and, according to Vattenfall, will use renewable electricity from the grid.
A 400-meter pipe connects the tank to four pumps to ensure that the hot water reaches the tank.”If hot water is added at the top, the same amount of cold water is taken out at the bottom,” the utility says on its website. “Therefore, only the quantity ratio between hot and cold water in the storage facility changes, not the total amount. amount of water.”
At the beginning of July, Vattenfall started filling the water tanks for the first time and using partially desalinated and degassed water to reduce wear and tear on the Berlin city heating network.The filling operation should last about two months.
