Geothermal heat extraction system deployed at Fujitsu's Nagano plant
Technology ( 4 )
TOKYO —
Fujitsu has announced the first deployment of a geothermal heat extraction system at its Nagano plant.
The new system employs heat extraction pipes that have been embedded in the ground beneath the plant. Geothermal heat extracted from these pipes is used as a heat source to power water heater equipment for air conditioners used in clean rooms and other 24/7 facilities.
By leveraging geothermal heat, which excels in terms of its stability and cost, Fujitsu said it expects to cut its annual fuel consumption by roughly 47kL (crude oil equivalent) and annual CO2 emissions by roughly 120 tons compared to the existing system.
In the future, after verifying the effectiveness of the new system and collecting operational know-how, Fujitsu will explore lateral application of the system to other locations.

Excellent! If systems like this were installed in every significant building in Japan, it would go a long way toward eliminating the need for nuclear power.

Gee, it took a long time for Japan to realize they had this resource. The technology isn't new. You would have thought in a country with natural steam coming out almost everywhere, this would have been done decades ago.

Geothermal generates less than 1% of total power, but experts in that field have stated that 15% would be possible.
"a long time for Japan to realize they had this resource."
They have been sitting in outdoor hot springs for hundreds of years.
