South Korean independent power producer Hanwha Energy plans to convert one of its boilers from being co-fired to fully biomass-fired starting September.

Hanwha Energy's Gunsan plant has a generation capacity of 99MW and currently uses coal as its primary fuel for power generation, with biomass as its secondary feedstock. One of its boilers will use domestic wood pellets and wood chips as its primary biomass feedstocks after the conversion. Argus could not immediately confirm the proportions.

Hanwha previously sought imported wood pellets as the main biomass fuel.

Hanwha's switch to a dedicated biomass-fired boiler will likely cause a fall in demand for imported industrial grade 3 (I3) wood pellets. Dedicated biomass-fired plants usually seek wood pellets with a higher industrial-grade quality, such as I2 and above. Domestic wood pellets from South Korea are typically of a better quality compared with imported wood pellets, which are usually of I3 quality shipped from southern Vietnam.
