Background

The power station is fueled with coal and tires and is located in Hiroshima, Chūgoku Prefecture, Japan. Daicel's 2020 Report noted the following about the Otake power station:

"In August 2007, the plant started selling its excess electricity. In July 2016, it installed an additional boiler. Two dualfuel boilers are run in parallel using a mix of coal and scrap tires as fuel."

"At the Ohtake Plant, a mix of coal and scrap tires is used as fuel for its boilers. Using a mixture that contains at least 46% of scrap tires enables the generation of steam and electricity that emits less CO2 than LNG, a lower carbon fuel. Excess electricity is sent to our other business sites using a self-consignment system and also sold externally to start-up energy companies. We are improving this process continuously by procuring higher quality scrap tires, ensuring stable boiler operation, and using a fuel mix with a higher scrap tire ratio. We have recently been working toward a ratio of over 50%."

The 50 MW Unit 6 (or 6-3) began operating in 2007 and the 38.5 MW Unit 7 (or 7-4) began operating in 2016.
