Australia's silicon producer Simcoa will likely need to buy and surrender Australian Carbon Credit Units (ACCUs) until 2028 for safeguard mechanism compliance obligations before it completes a key decarbonisation project, it told Argus today.
The project was awarded federal funds on 20 March. Australia's federal Labor government granted Simcoa A$39.8mn ($25mn) under its Powering the Regions Fund (PRF) to expand charcoal production at its Wellesley facility in Western Australia (WA) and remove the use of coal in silicon production. The project is expected to reduce the company's scope 1 emissions by around 90pc, or approximately 100,000 t/yr of CO2 equivalent (CO2e).
Simcoa is Australia's only silicon manufacturer, which is a key component of solar panels. The funding will help maintain silicon manufacturing capability in the country in addition to cutting emissions, energy minister Chris Bowen said.
The company currently uses 35,000 t/yr of metallurgical low ash coal in its operations, and anticipates usage will drop to zero after it doubles its charcoal production capacity by 25,000 t/yr to 50,000 t/yr. The completion date for the expansion is not expected before 2028.
The firm may continue to buy [ACCUs] as it must use coal as a reducing agent for part of its production for calendar years 2025-27, or until the expansion project can be commissioned, the company told Argus on 21 March.
Simcoa surrendered 22,178 ACCUs in the July 2022-June 2023 compliance year as it reported scope 1 emissions of 122,178t of CO2e with a baseline of 100,000t CO2e at its Kemerton silicon smelter. Figures were lower for the July 2023-June 2024 compliance period, the company said, without disclosing details. Australia's Clean Energy Regulator (CER) will publish 2023-24 safeguard data by 15 April.
Simcoa anticipates scope 1 emissions at the Kemerton smelter to be "considerably below" the baseline once the charcoal expansion is completed and could make it eligible to earn and sell safeguard mechanism credits (SMCs), which traded for the first time in late February. "We will take whatever opportunity is available to us," the company said on potentially holding or selling SMCs in future.
