"Heat stored underground in caverns can be set aside in Finland’s summer months to be re-used during frigid winters thanks to a state-of-the-art ‘seasonal energy’ storage facility.
Slated for construction this summer near Helsinki, it will be the largest in the world by all standards and contain enough thermal energy to heat a medium-sized city all winter.
Thermal exchange heating systems, like those built underground, or domestic heat pumps, are seen as the most effective way available of reducing the climate-impact of home heating and cooling.
Their function relies on natural forces or energy recycling to cool down or heat up water and then using it to radiate hot or cold energy into a dwelling.
In Vantaa, Finland’s fourth largest city neighboring the capital of Helsinki, the ambitious Varanto seasonal energy storage project plans to store cheap and environmental friendly waste heat from datacenters, cooling processes, and waste-to-energy assets in underground caverns where it can be used to heat buildings via the district heating network whenever it is needed.
In Finland and other Nordic countries, the heat consumption varies significantly between seasons. Heat consumption in the summertime is only about one-tenth of the peak load consumption during the cold winter months.
Varanto will utilize underground caverns equal in space to two Maddison Square Gardens—over a million cubic meters—filled with water heated by this waste heat and pressure that will allow the water to reach temperatures of up to 300 degrees Fahrenheit without the water boiling or evaporating.

“The world is undergoing a huge energy transition. Wind and solar power have become vital technologies in the transition from fossil fuels to clean energy,” says Vantaa Energy CEO Jukka Toivonen.
“The biggest challenge of the energy transition so far has been the inability to store these intermittent forms of energy for later use. Unfortunately, small-scale storage solutions, such as batteries or accumulators, are not sufficient; large, industrial-scale storage solutions are needed. Varanto is an excellent example of this, and we are happy to set an example for the rest of the world.” ...
“Two 60-MW electric boilers will be built in conjunction with Varanto,” adds Toivonen. “These boilers will be used to produce heat from renewable electricity when electricity is abundant and cheap. Our heat-producing system will work like a hybrid car: alternating between electricity and other forms of production, depending on what is most advantageous and efficient at the time.”
... Construction of the storage facility’s entrance is expected to start in summer 2024, while it could be operational as early as 2028."

“I’m wearing my dad’s old jacket which he hesitantly gave to me since apparently it’s too ’raggare’ for me. The scarf is my late grandma’s. The skirt is a second hand kids skirt. The pants are resized by me and my dear friend. And the shoes have gotten very slippery but I like to stuff the pant legs inside them. I pay attention to silhouettes and a general vibe and I’m inspired by noticing and combining.”

“I plan to keep my head warm and feet dry this winter. That is why I recently invested in proper winter boots and this storm proof hat by Vyner Articles. The rest is thrifted or hand-me-downs.Comfort, layers and petrol blue inspire me.”
