Enhanced Gas

Production from Coal
Seams by Methanogens

NSW and Queensland host an estimated 235 trillion cubic feet of coal seam gas resources ( an emerging global low carbon emission energy ), the majority of these resources being biological in origin . Direct electron transfer to methanogenic archaea , native to major coal seams has been shown to boost biological methane production . Other abundant organic feedstocks like biosolids from wastewater , agricultural waste and food waste , can also be digested to produce biogas .

Competitive Advantage

• Synthetic phenazine crystals have been found to facilitate direct electron transfer to methanogenic archaea to enhance methane production by an order of magnitude representing a positive shift in increasing methane production . Leveraging a deep understanding of the microbiology and biochemistry of biogas production , we can develop enhancement strategies and troubleshoot underperformance of anaerobic digestion systems .

Impact

• Enhancing biogas production in-situ in real-time helps sustain coal seam gas production at its current level . It represents a solution to reduce the environmental impact of the industry and increase profit margins by reducing infrastructure expenditure . Anaerobic digestion converts waste-toenergy , thereby lowering operational costs .
• Culture collection of methane producing microorganisms
• Biomethane potential testing expertise and equipment
• Expertise in feedstock pretreatment for anaerobic digestion
• Expertise in electron shuttle-based biogas enhancement
