Enhanced productivity of coal seam gas wells by continuous gas circulation. This project aims to develop foam assisted continuous gas circulation for dewatering new and existing coal seam gas wells. The potential benefits of this new method include enhanced gas production, better well control, reduced costs and better environmental effectiveness.

This project aims to develop foam assisted continuous gas circulation for dewatering new and existing coal seam gas wells. The potential benefits of this new method include enhanced gas production, better well control, reduced costs and better environmental effectiveness. The proposed solution eliminates the need for mechanical pumps which are currently used for dewatering, and which fail regularly due to gas and solids accumulation within the production wells. Continuous gas circulation could achieve significant savings in downtime and maintenance costs. In addition, reducing onsite maintenance will minimise access requirements for maintenance rigs which disrupt rural activities where the wells are located, thus easing local traffic and reduce the environmental impacts that are associated with well workovers.Read moreRead less

Summary
Developing advanced potassium-sulfur batteries for scalable energy storage. Potassium-sulfur (K-S) batteries are recognised as a promising energy storage technology for large-scale applications, due to their high theoretical capacity, low toxicity and the low cost of both potassium and sulfur. However, their grid-scale development is plagued by safety hazards and fast capacity fade. This project aims to address these challenges by developing atomic-level engineering of host materials for sulfur, ....Developing advanced potassium-sulfur batteries for scalable energy storage. Potassium-sulfur (K-S) batteries are recognised as a promising energy storage technology for large-scale applications, due to their high theoretical capacity, low toxicity and the low cost of both potassium and sulfur. However, their grid-scale development is plagued by safety hazards and fast capacity fade. This project aims to address these challenges by developing atomic-level engineering of host materials for sulfur, K metal anode and solid electrolyte. The outcomes of this project will provide increased understanding of the mechanism for K-S batteries and novel strategies for their development, placing Australia at the forefront of K-S batteries for scalable battery research and supporting our cutting-edge energy storage technology.

Thermal decomposition of PFAS. This project aims to investigate the thermal decomposition of per- and poly-fluroalkyl substances (PFAS). The project will focus on the catalytic destruction of PFAS reactions at elevated temperatures, which is expected to transform PFAS in a controlled and predictable way into benign products.

This project aims to investigate the thermal decomposition of per- and poly-fluroalkyl substances (PFAS). The project will focus on the catalytic destruction of PFAS reactions at elevated temperatures, which is expected to transform PFAS in a controlled and predictable way into benign products. By understanding the fate of these compounds during thermal decomposition, the project will allow the development of a new technology aimed at treating materials which have been contaminated with or have been used as absorbants for PFAS. The project will provide the technical underpinning of a new technology developed to treat fluorochemical-contaminated material and, in doing so, reduce the environmental impact of these contaminants.Read moreRead less

This project aims to develop a particle scale microprobe to capture the transient dynamics of biomass compaction, dilation and associated airflow for pneumatic conveying and potentially beyond. Low velocity, dense phase pneumatic transport presents the ideal method for transporting delicate biomass feedstocks. However, without the fundamental understanding of the compactive and dilative response of biomass ensembles, pneumatic conveyors will be over-designed and energy intensive. This project will enable accurate measurement of the motion, inertia and force information at the particle scale, to produce more accurate design protocols for dense phase biomass pneumatic transport.Read moreRead less
