Hatchobaru Geothermal Power Plant ()
Oita Prefecture in Kyushu is home to over 4,000 hot springs and is known as the onsen capital of Japan. Here you can enjoy this geographic feature with therapeutic baths and even sample some delectable dishes steamed using the heat from below ground. But did you know Oita’s hot waters also contribute to clean energy?
In Oita, geothermal energy is being harnessed for power and hydrogen. Kyushu Electric Power Company’s Hatchobaru Geothermal Power Plant in Kokonoe Town generates 110,000 kilowatts of electricity per hour, which is enough to power around 37,000 homes for one year.
The plant’s use of geothermal does not emit carbon dioxide into the atmosphere and saves Japan from consuming 200,000 kiloliters of oil for power generation every year, according to Kyushu Electric Power Company.
The Hatchobaru plant also offers guided tours and lectures at its museum so you can learn more about its operations and renewable energy.
Another plant using geothermal energy is Obayashi Corporation’s hydrogen plant in Kokonoe Town. This plant produces “green hydrogen,” which is hydrogen created without emitting carbon dioxide in the production process.
Hydrogen is considered as a next-generation portable energy because it can be stored in canisters and transferred to local hydrogen fuel stations. According to the company, the plant can produce one kilogram of hydrogen per hour, which is enough for a fuel-cell vehicle (FCV) to drive 130 kilometers.
Oita’s spring waters are not only a source of relaxation, but also a source of clean, sustainable energy. So, next time you’re in the area, enjoy the hot springs and check out the impressive ways these waters are being used to save the environment and preserve natural resources.
