City to install massive underground thermal energy storage facility: ‘The world is undergoing a huge energy transition’

Posted by in categories: solar power, sustainability

Now that we can generate clean, renewable energy from the wind and sun, one of the most pressing questions facing the clean energy transition is how to effectively store that energy for future use. For one city in Finland, the answer is a giant underground cavern.

Vantaan Energia has announced that it will construct a massive underground seasonal thermal energy storage facility for the city of Vantaa, the country’s fourth-most-populous municipality. The facility will be twice the size of Madison Square Garden, New Atlas reported.

“The world is undergoing a huge energy transition,” Vantaan Energia CEO Jukka Toivonen said. “Wind and solar power have become vital technologies in the transition from fossil fuels to clean energy. 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.”
