Why did Helsinki close its last coal power plant?
Helsinki has officially closed its last coal power plant, cutting the city’s carbon emissions by 30 percent and marking a key milestone in Finland’s green transition.
What is the Pyhäsalmi Mine?
The Pyhäsalmi Mine, roughly 450 kilometres north of Helsinki, is Europe’s deepest zinc and copper mine and holds the potential to store up to 2 MW of energy within its 1,400-metre-deep shafts. The disused mine will be fitted with a gravity battery, which uses excess energy from renewable sources like solar and wind in order to lift a heavy weight.
Does Helsinki still use coal?
Until recently, coal played a dominant role in Helsinki’s energy supply. In 2022, coal still accounted for 64 percent of Helen’s district heat production. The end of coal does not mean a single replacement source. Instead, Helsinki’s heating is now distributed across several technologies.
Could a Pyhäsalmi Mine be transformed into a giant battery?
An abandoned mine in Finland is set to be transformed into a giant battery to store renewable energy during periods of excess production. The Pyhäsalmi Mine, roughly 450 kilometres north of Helsinki, is Europe’s deepest zinc and copper mine and holds the potential to store up to 2 MW of energy within its 1,400-metre-deep shafts.
Can gravity repurpose a disused shaft at Pyhäsalmi Mine?
Pyhäsalmi mine. Image credit: Gravitricity Plans have been announced to repurpose a disused shaft at the Pyhäsalmi Mine in Finland into an underground energy storage, using technology developed by Gravitricity. The Pyhäsalmi Mine, owned by Canadian mining corporation First Quantum Minerals, is located 450km north of Finland’s capital, Helsinki.
Why should Finland close coal-fired energy plants?
“Closing the coal-fired energy plants is an important and historical change for Helsinki, Finland and, ultimately, the whole planet,” said Juhana Vartiainen, Mayor of Helsinki. “Cities the world over have assumed a leading role in the fight against climate change.
