With Denmaru-kun, Japan reduces CO2 emissions by 2,400 tons!!
The power energy from load testing of self-generated power equipment has not been utilized until now. The power storage load device "Denmaru-kun" is equipped with a storage battery for EVs. It is now possible to store energy during load operation and use it as power for offices and EVs. According to a survey by the Japan Internal Combustion Engine Power Generation Association, the nationwide registered number of fire-fighting and emergency generators is approximately 220,000 units. Assuming an average diesel generator of 100 kW, operating at 1/3 load for 30 minutes emits about 10 kg of CO2. If all emergency generators conduct load testing with "Denmaru-kun," it would be possible to reduce CO2 emissions by approximately 2,400 tons, equivalent to the amount absorbed by 170,000 cedar trees in one year (according to our research). This CO2 emission reduction project is promoted by JESA. For more details, please contact us or refer to the catalog.
