Indonesia's PLN to build biomass production facility
A unit of Indonesian state-owned utility PLN will build a biomass production facility in Medan city, North Sumatra province, to support the group's coal-biomass co-firing efforts.
The pilot project, under PLN Indonesia Power (PLN IP), is in partnership with the city government. The project will use Medan's solid waste, which is typically dumped at garbage dump TPA Terjun, to produce 16 t/month of biomass. The biomass will have a nominal caloric value of 3,400 kcal/kg.
The produced biomass will be used at PLN's 840MW Pangkulan Susu coal plant located in Pasir, North Sumatra and will account for 3pc of the power plant's fuel needs. The Pangkulan Susu coal plant is one of the main baseload power plants for North Sumatra, supplying 29pc of the electricity needs in North Sumatra. The use of biomass co-firing on a must-run baseload power plant would result in lower emissions compared to biomass cofiring in peaking power plants, PLN said.
PLN has been implementing biomass co-firing in many of its coal plants, as part of the company's efforts to lower emissions. It has implemented co-firing at 43 of its coal plants in 2023, consuming 1mn t of biomass over the course of the year, reducing carbon emissions by 1.05mn t to date. It plans to expand it to 52 coal plants by 2025.

Japan's Ozu biomass power plant starts operations
Tokyo, 1 August (Argus) — The 50MW Ozu biomass power plant in south Japan's Ehime prefecture came on line today, having started construction in June 2022. It will burn around 200,000 t/yr of wood pellets imported mainly from southeast Asia to generate 350 GWh/yr of electricity. All the electricity generated will be sold to power utility Shikoku Electric Power Transmission and Distribution for 20 years under Japan's feed-in-tariff scheme. Ozu is operated by a joint venture that is 57.6pc owned by construction company Maeda Kensetsu, 35pc by upstream firm Japex, 6.4pc by Shikoku Electric Power's subsidiary Yonden Business and 1pc held by engineering firm Shinko Denso. Japex has invested in two 9.9MW biomass power units in Japan's northernmost Hokkaido prefecture, with the Abashiri No.2 and No.3 starting operations in October 2022 and March 2023 respectively. Its 75MW Chofu and 50MW Tahara biomass power plants are currently under construction. Chofu will start in January next year followed by Tahara in April.

India’s Tata Steel tests biomass at ferro-chrome plant
India’s Tata Steel tests biomass at ferro-chrome plant
Singapore, 29 July (Argus) — India's Tata Steel has carried out a trial using charcoal as a feedstock at its domestic ferro-chrome unit, with it also open to importing the biomass product. It said it finished the trial on 20 July, in which it replaced conventional reductants such as coke in the Athagarh ferro-chrome plant in east India's Odisha state with carbon-neutral biomass charcoal, made from the low-temperature burning of wood in an oxygen starved atmosphere. The carbon released during the ferro-chrome production process was balanced by carbon absorbed by the trees from which wood for the charcoal was taken, it added. The trial was part of Tata Steel's sustainability drive to cut emissions from its operations. Athagarh has ferro-chrome production capacity of 55,000 t/yr. The use of 5pc of biomass in production is expected to lower carbon dioxide (CO2) emissions by 0.08/t of ferro-chrome, Tata Steel said, which is about 6pc of total CO2 emissions from the plant. The company is carrying out more trials and feasibility studies to stabilise the use of biomass in ferro-chrome production, it said, adding that plans to commercialise biomass use as a feedstock have not been finalised yet. Tata Steel might also consider imports of charcoal if is commercially and technically feasible. Tata Steel is also working with Australian resources firm BHP to adopt low-carbon iron and steel production . This includes using biomass and carbon capture and utilisation technology, which could cut emissions by up to 30pc for integrated steel mills.

Idemitsu to start black pellet output in December
Idemitsu to start black pellet output in December
Tokyo, 23 July (Argus) — Japanese energy firm Idemitsu is planning to start black pellet production of 120,000 t/yr in Vietnam in December this year. Idemitsu has already completed construction of the black pellet plant in Vietnam's Binh Dinh province in July 2023 and is now carrying out test operations. The black pellets produced at this plant will be transported to Japan for consumers that include power generation companies operating coal and biomass co-firing. The Vietnamese plant is managed by Idemitsu Green Energy Vietnam, which has become a 100pc subsidiary of Idemitsu in March this year. Idemitsu is planning to increase its black pellet output to 300,000 t/yr within three years after the start-up of the first plant. It final target is 3mn t/yr by 2030 , with an aim to launch projects in Malaysia and Indonesia in addition to Vietnam. The company is also considering empty fruit bunches as feedstock for biomass fuels. Idemitsu has been carrying out studies of coal and biomass co-firing and confirmed that it is possible to burn 35pc of black pellets with coal. The company has provided utilities with samples for test runs. Black pellets also can be used in other sectors, such as steel mills and cement plants. Black pellets, which have a higher calorific value compared with typical white pellet biomass, are produced by the torrefaction of acacia and other feedstock. The advanced fuel has better water resistance and grindability than white pellets and can be used in a similar way as coal.

Japan’s Erex cuts biomass-fired power output in June
Japan’s Erex cuts biomass-fired power output in June
Tokyo, 15 July (Argus) — Japanese renewable electricity producer Erex reduced its biomass-fired power generation output in June compared with a year earlier, according to the company data. Erex's combined biomass-fired output across the 50MW Saiki, the 75MW Buzen, and the 49MW Nakagusuku power plant in June fell by 8.5pc from a year earlier to 108GWh. The company does not publish output data for its 75MW Ofunato plant, while the 20MW Tosa plant has been under periodic maintenances since March. Erex operates a total of 269MW of biomass capacity in Japan, including Ofunato, burning mainly imported wood pellets and palm kernel shells. The company aims to start coal and biomass co-firing generation at the 149MW Itoigawa plant that has only consumed coal so far. The company plans to start operations at two more biomass plants, the 75MW Sakaide Hayashida in 2025 and the 300MW Niigata Mega Bio around 2029-2030. Erex is also accelerating biomass projects in southeast Asia, aiming to build up to 19 generation plants in Vietnam and five in Cambodia that will burn mainly wood residue and chips, in addition to several wood pellet plants in both countries.
