Biomethane production costs and cost drivers
Shelby does not report measured costs from an active Australian production project. The response cites published pathway-specific cost ranges and recommends transparent project economics, separating costs, support and co-product revenues rather than imposing a universal tariff.
Shelby’s position, not adopted government policy or confirmation of lodgement. Historical evidence and policy-modelling assumptions are distinguished in the response.
The official consultation question
Q21 · §4.1(a) · paper page 25
What are your current and projected levelised costs (A$ per GJ) over the next 5–10 years, broken down by technology type and scale? Please describe the key cost drivers behind these estimates, including any assumptions or factors that may influence future cost trajectories.
Shelby’s response
Shelby Bioenergy does not currently have an active Australian production project from which to report measured levelised costs. However; since our launch in Australia 2021 we have worked closely with well established international groups such as “Verdemobil” on detailed optimisation and modelling of over 50 biogas-upgrading / biomethane-injection sites and approximately 20 biogenic-CO2 liquefaction sites across France and Europe. Their installed base provides practical experience in repeatable modular engineering, commissioning, gas-quality control, operation and maintenance, grid injection, CO2 purification and liquefaction, storage and commercial product qualification.
Australian studies nevertheless provide a useful evidence base. Recent published estimates place biomethane production broadly around A$10-13/GJ for landfill pathways, A$15-25/GJ for anaerobic digestion of wastes and A$28-36/GJ for crop-residue pathways, with strong dependence on feedstock, scale, upgrading, connection and delivery.
Shelby therefore recommends that policy be designed against transparent project economics rather than a single universal tariff.
Typical drivers include feedstock collection and treatment, plant capacity and utilisation, energy consumption, methane recovery, financing, maintenance, connection and delivery. Existing-facility upgrades can reuse infrastructure, but must account for any displaced heat or electricity production. Over the next 5–10 years, standardised equipment and repeated installations offer opportunities to reduce costs; Australian forecasts should be established through supplier quotations and local operating evidence, with production costs, policy support and co-product revenues reported separately.
