GHG Reduction Initiatives 5. Expanding Supply of Biomass Fuels

Expansion of Biomass Fuel Supply

Even as we strive to promote renewable energy generation projects, we are engaged in biomass fuel-related operations as part of our efforts to supply energy from sources with lower carbon footprints. Specifically, we are developing black pellets, a biomass fuel that can be co-fired with coal at coal-fired power stations to reduce CO2 emissions. Black pellets are made by pulverizing, drying, and roasting wood to semi-carbonize it.
Compared with conventional white pellets, black pellets boast superior properties, including water resistance, and are easier to crush. Along with these features, they can be handled in the same way as coal. This makes it possible to reduce coal consumption without modifying existing power generation facilities while increasing the use of renewable energy sources in the form of black pellets.
In fiscal 2021, having conducted a co-firing test with coal at the Tokuyama Complex, we did the same at boilers at the Chiba Complex as well. We are currently preparing to begin commercial production in fiscal 2022. (The product name for our black pellets is Idemitsu Green Energy Pellets.)
We aim to supply 2.0 million tons of Idemitsu Green Energy Pellets in 2030 and plan to continue working to expand production sites, especially in Southeast Asia, including Vietnam, Malaysia, Indonesia, and Thailand.

Conducting a Co-firing Test with Black Pellets and Coal at the Chiba Complex

In April and May 2021, we conducted a co-firing test of coal and black pellets at the Chiba Complex. The test was undertaken with an eye to reducing GHGs and establishing incineration technologies for circulating fluidized bed boilers. For the co-firing test conducted employing boilers at the Chiba Complex, we used around 1,000 tons of black pellets shipped from our overseas demonstration manufacturing site and then unloaded and stored domestically. Going forward, we will evaluate the test results, identify issues pertaining to the launch of full-scale operations, and accelerate initiatives aimed at fostering internal cooperation to reduce the Company’s GHG emissions as well as the eventual sale of related technologies to other companies.

Presenting Our Biomass Business at the ASEAN Bioenergy and Bioeconomy Conference

On June 6, 2019, the “ASEAN Bioenergy and Bioeconomy Conference 2019” hosted by Kasetsart University was held in Bangkok. Invited by the university, our engineer from Coal Coal Business Department gave a lecture on the technology of semi-carbonizing wood pellets (black pellet). Currently, Idemitsu Kosan is working on black pellets production in Thailand.

During the event, we had an active opinions exchange with local biomass-related companies, and many participants expressed their expectations to Idemitsu as we presented our plan regarding biomass commercialization.
