The Problem

Methane abatement is now one of the most urgent and technically complex decarbonisation challenges facing Australia’s underground coal sector. Ventilation air methane is difficult to treat because it is highly dilute, carried in very large and variable airflows and constrained by mine ventilation and safety requirements. Waste gas streams create a different but related challenge: methane concentrations can be too low or too inconsistent for conventional flaring, particularly where high CO₂ content reduces the effective methane fraction and undermines stable combustion. Together, these streams sit in the difficult middle ground between conventional gas utilisation and unmanaged fugitive emissions.

The regulatory and commercial imperative is also increasing. Australia’s Safeguard Mechanism applies to large industrial facilities and progressively lowers emissions baselines, requiring facilities to manage excess emissions and creating stronger incentives for on-site abatement. At the same time, investors, customers and communities are placing greater scrutiny on credible greenhouse gas reduction pathways. For coal mines with material fugitive methane emissions, abatement is no longer a future-facing option; it is becoming central to maintaining compliance, competitiveness and social licence.

The Opportunity

The opportunity is to move methane abatement from fragmented trials and site-specific workarounds into a structured, evidence-based pathway for deployment. Catalytic oxidation, catalytic flare concepts, gas-to-solid conversion and gas-to-liquid pathways each offer different value propositions depending on gas composition, methane concentration, flow variability, available heat or power integration, carbon product potential and site constraints. No single pathway will suit every mine; the value lies in matching the right technology to the right methane source and proving performance under realistic operating conditions.

Mining3 is well positioned to help industry make this transition. Building on the capabilities and experience that we have developed through the CATCH4 program, Mining3 can support mine operators and technology partners with independent technical assessment, process modelling, techno-economic evaluation, catalyst and reactor performance testing, site integration studies and commercialisation pathways. This enables mining companies to prioritise practical abatement options, quantify emissions and cost impacts, reduce technology risk and build credible investment cases for full-scale deployment.

Call to action

Mining companies, technology providers and investors seeking credible pathways to reduce methane emissions are invited to partner with Mining3. We can help organisations understand their methane challenge, identify where catalytic oxidation and related conversion technologies create value, and progress the most promising options from concept through testing, piloting and commercial deployment. By supporting Mining3’s methane abatement work, industry can accelerate practical emissions reduction, strengthen Safeguard Mechanism compliance, and help build the next generation of deployable decarbonisation solutions for Australian and global mining.
