Ema Frery

Dr Emanuelle Frery is a senior research scientist leading a research team at the CSIRO, the Australian Science institute. Her team focus on natural hydrogen systems and CCS with a multidisciplinary approach, from the lab to the field. She acquired a worldwide academic expertise in structural geology with a PhD thesis on the fluid and gas circulation along natural faults recorded in the well-known red sandstone of the Colorado Plateau and her implication in the IODP research on active serpentinite mud volcanoes. She is an expert of risk assessment of energy production impact on the environment and socio-economical assets and acted as deputy lead in the $34.5 million GBA programme. She is the AFRAN WA Hub leader and a member of the IEA Hydrogen TCP committee on natural hydrogen - task 49

What is happening in Asia? - Natural hydrogen systems in australia, state of knowledge
Hydrogen directly coming from the Earth could represent an alternative source of decarbonized hydrogen and potentially provide the opportunity to rapidly scale up green hydrogen production for domestic use and export. Exploration programs aiming to find natural H2 reserves at economic scale are now active worldwide, but the geological contexts favourable to generate and accumulate such gas at depth remain poorly constrained. Hydrogen can be naturally produced by various processes in the subsurface. Here, we review and discuss the generation processes as well as the elements of the hydrogen system through recently investigated case studies located in South Australia and Western Australia.These case studies, including the well-known Gold Hydrogen Ramsey prospect, integrated new datasets acquired: 1) in the field with soil-gas surveys and ground water analyses around potential natural seeps, and 2) in the laboratory on samples from historic well cores and cuttings to investigate the subsurface geofluid paleo-migrations, the oxidation processes, the generation potential and characterise the geomechanical and transport properties of selected potential sources, reservoirs and seals. Finally, conceptual geological models of hydrogen prospectivity were developed to discuss the weight of each generation process and to integrate the elements of the system at a regional scale.  Co-authors: Dr. Ema Frery1, Dr. Julien Bourdet3, Dr. Claudio Delle Piane1, Dr. Melissa Duque NK1, Krista Davies1,2, Dr. Charles Heath1, Dr. Se Gong1, Dr. Bhavik Lodhia1, Dr. Jelena Markov1, Dr. Mustafa Sari1, Dr Siyumini Perera1, Dr. Joel Sarout1, Dr. Julian Strand1CSIRO Energy2.
