Guest Speaker(s): Trey Meckel (Monteverde Energy/Groundbreaking Energy/Australian Geothermal Association)

Dr Lawrence (Trey) Meckel is an experienced leader in the global energy industry, and an expert in alternative energy, decarbonization, and oil and gas. During his career, spanning more than 30 years, he has identified, matured, commercialized, and operated energy projects in Australia, SE Asia, North America, South America, and Africa.

He began his career with Shell and Woodside, as was VP of Exploration of Latin America’s largest energy company from 2017-2022. Presently, Dr. Meckel is CO2 Storage Project Manager at CO2CRC, Australia’s leading CCS organization. He is also the founder of Monteverde Energy, where he is involved in geothermal projects in Western Australia and the USA, and co-founder of Groundbreaking Energy, a geothermal exploration company.

Other roles include Secretary of the Australian Geothermal Association and Tutor at the University of Cambridge (UK) Institute for Sustainability Leadership (CISL), training senior executives across multiple sectors in net-zero strategies.

Hot Sedimentary Aquifer (HSA) Exploration and Development in Australia

Presented by Trey Meckel (Monteverde Energy/Groundbreaking Energy/Australian Geothermal Association)


Geothermal energy from Hot Sedimentary Aquifers (HSA) has significant potential in Australia. To date, the potential has been realized in multiple, small-scale (1-2.5 MW-th), direct use projects in the Perth Basin in Western Australia (WA) and in the Otway and Gippsland Basins in Victoria (VIC). These projects were limited by demand, not resource; current projects, planned at scales of 5-25 MW-th, include large-scale greenhouse projects in WA, aquaculture in VIC, and district heating in South Australia.

In contrast, commercial power generation has been more elusive. The Birdsville power plant in Queensland successfully generated 80 kW-e for ~20 years, but other attempts to realize the potential, such as the Salamander-1 (2010) and Celsius-1 (2011) exploration wells and the Winton power project in Queensland, were, or are currently, commercially unviable. These latter projects represent significant learnings for the Australian geothermal industry, analogous to ‘dry holes’ in oil and gas exploration.

Based on these learnings, certain areas can be high-graded for HSA energy exploration, appraisal, and development. Most notably, Strike Energy, holding a Geothermal Special Prospecting Area (GSPA) over much of the northern Perth Basin (NPB), has recently announced an Inferred Resource of approximately 226 MW-e (P50) in the Kingia Sandstone, which is anomalously porous and permeable at depths where the reservoir has proven temperatures greater than 150°C. If commerciality is confirmed by further appraisal, this resource could contribute to decarbonizing fertilizer (Project Haber), oil and gas, mining, and other operations in the region, as well as providing reliable, on-demand power.

This talk will review the relevant history of HSA projects in Australia and then provide an up-to-date look at new efforts to exploit HSA in Australia, including recent high-impact exploration bid rounds in multiple states.
