Japan's 112MW Hibikinada biomass plant, which is being converted from coal and biomass co-firing to biomass-only combustion, will trial run in January 2025.
The plant in southern Japan's Fukuoka prefecture, which is held by housing and energy company Daiwa House Industry, will conduct test runs to examine if exhaust gas coming from biomass-only operations can meet environmental regulations and verify that the modified boiler can be stably operated. The construction for conversion started in April and nitrogen injection systems for preventing fires have already been installed.
Daiwa will resume conversion works in mid-2025 after evaluating results from the first test runs, and complete it by April 2026. It aims to start biomass-only combustion operations around April 2026 to generate 980 GWh/yr of electricity. Of this, 30pc will be sold under Japan's feed in tariff (FiT) scheme while the company is considering other ways to sell the remaining 70pc, including long-term power purchase agreements (PPAs) and electricity capacity auctions.
The plant started operations as a coal and biomass co-firing power plant in February 2019, burning 70pc of coal and 30pc of imported wood pellets. Daiwa bought the operating company in January 2023 and announced it willconvert the project to biomass-only combustion in April 2023, then halted operations in April 2024 for conversion. It will burn up to around 450,000 t/yr of wood pellets after converting to biomass-only combustion.
Daiwa is aiming to develop more than 2,500MW of renewable energy capacity around 2030, including solar, wind, hydro, and biomass-fired power generation.
