Glenorchy Landfill Gas Upgrade Project

Glenorchy Landfill Gas Upgrade Project is an electricity generation from landfill gas project located in Glenorchy, approximately 7km northwest of the central business district of Hobart in Tasmania. It was registered in July 2022, and while the exact project area size is not publicly detailed on the register, it operates within an active municipal landfill facility. The immediate land use is industrial and waste management, whereas the broader Greater Hobart and Derwent Valley region is characterized by urban settlement, native forestry operations, and agricultural grazing. The local environment experiences a temperate climate with moderate annual rainfall, and regional soils generally consist of podzolic clay loams and dolerite-derived soils.

Electricity generation from landfill gas projects involve installing or upgrading infrastructure to collect methane gas emitted from decaying organic matter. Standard requirements mandate that this captured gas, a highly potent greenhouse gas, must be combusted in an internal combustion engine or similar biogas upgrading system to produce electricity. The project’s abatement is calculated using the electricity produced, ensuring that methane emissions are reduced while simultaneously substituting fossil-fuel energy production.

For this specific project, the proponent, LMS Energy Pty Ltd, upgraded an existing gas collection system to capture and combust emissions generated from both legacy and non-legacy waste at the facility. Interestingly, in June 2024, the project underwent a methodology variation, transitioning from the older 2015 Landfill Gas determination to the updated 2021 Electricity Generation from Landfill Gas Methodology Determination. This allows the facility to continue accurately generating Australian Carbon Credit Units (ACCUs) under the latest regulatory framework for electricity generation.
