Stockholm isn’t surrounded by nature – it is nature. About 40 percent of the city’s area consists of green space and has 14 islands, 30 public beaches, and eight protected natural reserves. So even though Stockholm is growing, it remains very green. Stockholm is one of just 11 global cities to meet all the requirements of the “Compact of Mayos”, an ambitious action plan to fight climate change.
What makes it so innovative?
- Stockholm is known for one such innovation called the “EnergyHub” system developed by Ferroamp, which is a Stockholm-based tech company. The system boosts output and increases flexibility in solar power installations, by capturing and storing solar energy more effectively. The traditional solar inverter only works when the sun shines, but in this case, EnergyHub continues at night and all through the winter.
- Another one is hot water, cool solutions, it is a remarkable energy solution called “Climeon” that turns hot water into electricity. The Climeon system uses the temperature difference between hot and cold water to create a pressure difference. This pressure difference drives a turbine and the turbine drives a generator – and out comes electricity. The whole system works in a vacuum, that keeps the pressure so low in the system that it needs very little material and wastes very little energy. It’s extremely efficient.
Many innovations born in the Swedish capital aren’t just thanks to its passion for sustainability, but also the stability of the country itself. Stockholm is a full house of culture, climate, talent hence it is the innovation hub of Sweden.”
