energy storage illustrator artwork service devices can release heat to warm the water, providing heat for district heating, which can flow to homes, offices and local swimming pools. Cost saving gains The concept of "sand batteries" was first born in a former pulp mill in the city of Tampere, where the local government donated the workshop and provided funds to help them start. An energy and climate expert in the city, Alina. "Energy bills will be particularly expensive if some power plants only operate for a few hours a day during the coldest part of the winter," said Elina Seppänen, chief executive of the company.
"But I think if we have a solution like this that allows us to flexibly use and store the heat, it can be very helpful in reducing costs." One of the biggest challenges is how to scale up this technology so that it can bring about substantial change. In addition, in addition to using such devices to store heat, can researchers use them to generate electricity? When the heat stored in the sand is converted into electricity and fed into the grid, the efficiency is drastically reduced. But long-term storage of green energy is itself a huge opportunity for industry, which relies on fossil energy for heating in food, beverages, textiles or pharmaceuticals. Other R&D teams, such as the National Renewable Energy Laboratory in the United States, are also actively exploring the use of sand as a means of green energy storage. But it was the Finns who made the commercial equipment first, and according to the system's investors, their equipment is currently working well.
"The equipment is simple, but we like the idea of trying something new and want to be the first in the world to do so," said Pekka Passi, head of the Vatayankoski power plant in Finland. "It seems kind of crazy, if you can say that, but I think it's going to be a success."
