Researchers From Japan Develop Method To Generate Renewable Energy From Snow. The Expectation Is That The Electricity Generated Is Equivalent To Conventional Solar Panels.
Researchers from Aomori, a city in Japan, began studying methods to generate renewable energy from snow to provide a sustainable energy supply and address any electricity shortages. Aomori is a beautiful city in the country, located 715 km north of Tokyo. In addition to its attractive blue pine forests, the city is known for being one of the snowiest places on Earth, receiving about 25 to 26 feet (7.92 m) of snow per year.
Scientists From Japan Generate Energy From Snow With Pool Tests
In 2022, there was so much snow in the city that authorities spent about US$ 46 million, equivalent to 5.9 billion yen, just to remove it from buildings and roads. To get rid of so much snow, the Japanese throw it all into the sea.
This process may seem legal at first, however, it requires a lot of time, money, and resources. Therefore, a team of researchers from the IT startup Forte, based in the city, and the University of Energy and Communications (UEC Tokyo) proposed an interesting solution to the snow problem.

The scientists suggest that the extra snow in the city of Japan could be used to generate clean and affordable electricity. Snow ended up in energy, and scientists have already begun testing the technology in the pool of an abandoned school building.
The researchers believe that their approach could be useful for several European countries that are currently facing an energy crisis amid the Russia and Ukraine war. Most of these countries in Europe do not lack snow and could use it to generate renewable energy.
Scientists’ Method Uses Heat Pipes To Provide Cold Air And Hot Air
During research, Japanese scientists employed abundant amounts of snow and extreme air to power a turbine that generates electricity. Outside air obviously has a higher temperature than the air around the snow because it receives some heat from the sun.
Researchers will use heat pipes to provide cold air and hot air to the refrigerant liquid inside the turbine. The temperature difference between the cold air and hot air will create a convection current in the turbine’s refrigerant. This current will eventually make the turbine spin and generate energy from the snow.
The authors claim that their snow-based renewable energy generation method can achieve the same efficiency as a solar power plant, possibly in a much more cost-effective way. The effectiveness of this system also depends on the temperature difference factor. According to Koki Enoki, a researcher and professor at UEC, the greater the temperature differences, the higher the efficiency of energy generation.
Obstacles To Be Faced By Scientists
Unlike any other method of renewable energy production, the snow energy approach also presents significant challenges. For example, to make this process scalable, large snow storage facilities will be needed.
Additionally, a continuous supply of hot air in snowy regions may also be complicated for companies managing snow power plants. Researchers will conduct their study in the Japanese city until March to test the feasibility of the proposed method.
Meanwhile, they will also seek ways to harness hot air from geothermal sources for their system and overcome other limitations. The expectation is that the tests will be successful, and this snow-based energy generation method will give rise to a new revolution in renewable energy in cold regions of the world.
