The city of Aomori, which sees heavy snow every year, started a trial in a swimming pool at an abandoned elementary school in December [2022] to explore the feasibility of producing energy by utilizing the temperature difference between stored snow and the surrounding air.
According to Forte, challenges include finding a large-scale facility to store snow as well as securing heated air during cold seasons.
