Investigating the activity of indigenous microbial communities from Italian depleted gas reservoirs and their possible impact on underground hydrogen storage

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: April 24, 2024

H 2 produced from renewable energies will play a central role in both greenhouse gas reduction and decarbonization by 2050. Nonetheless, to improve diffusion utilization as fuel, large storage capacity systems are needed. Underground of natural depleted reservoirs, aquifers salt caverns is well-established technology. However, new challenges arise when it comes storing hydrogen due the occurrence activity indigenous microbial populations deep geological formations. In previous study, four Italian reservoirs were characterized hydro-chemical microbiological point view, predictive functional analyses carried out with perspective underground (UHS). present work, formation waters same used inoculant during batch cultivation tests characterize its effects on different mixtures. Results evidence predominant acidogenic/acetogenic activity, whilst methanogenic sulfate reducing only marginal for all tested inoculants. Furthermore, activation samples strongly influenced nutrient availability. Obtained results fitted screened computational model which would allow insights study context UHS.

“Innovative high pressure/high temperature, multi-sensing bioreactors system for microbial risk assessment in underground hydrogen storage”

International Journal of Hydrogen Energy, Journal Year: 2023, Volume and Issue: 51, P. 41 - 50

Published: Nov. 18, 2023

This study addresses the microbial risks associated with Underground Hydrogen Storage (UHS), a critical component in transition towards renewable energy systems, by employing an innovative multi-reactor system (Bio-xplorer) to simulate UHS conditions two Italian reservoirs. The microbiological risk assessment (MRA) of Reservoir A and B was evaluated subjecting them gas mixtures 10 % H2 90 CH4, 99 1 CO2, respectively. In A, stability pressure temperature, negligible optical density, lack metabolites suggested low activation. Molecular analyses confirmed absence sulphate-reducing bacteria (SRB) limited growth hydrogenotrophic methanogens (HM). Similarly, B, SRB occurrence HM indicated risk. Overall, present work supports safe efficient implementation UHS, promising mitigation technique for climate change, using tool MRA.

In situ field experiment shows the potential of methanogenic archaea for biomethane production from underground gas storage in natural rock environment

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 32, P. 103253 - 103253

Published: June 19, 2023

Biological methanation occurs naturally in the specific rock environment of some underground gas reservoirs. To use natural potential hydrogenotrophic methanogenic archaea reservoirs future for any type energy conversion, better knowledge these systems is required. Most studies investigating biological methane production from hydrogen and carbon dioxide have been conducted laboratory-scale systems, making it impossible to evaluate process under realistic environmental conditions. A unique field experiment biomethanation an reservoir confirmed feasibility facilities targeted biologically produced methane. The followed data previously obtained long-term experiments carried out laboratory, including 300 days lasting operation reactor cultivation experiments, which led repeated isolation Methanothermobacter sp. This species was dominant methanogen, raised 1% 43% all microbial population after 22 experiment, while complete conversion took place. In addition, study supported by metagenomic analysis gain deep insight into microbiome reservoir.
