The Sulfur Cycle01:22

The Sulfur Cycle

43.5K
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

Area of Science:

  • Microbiology
  • Geochemistry
  • Energy Storage

Background:

  • Hydrogen storage in salt caverns is crucial for the energy transition.
  • Microbial communities in these environments and their impact on hydrogen loss are poorly understood.

Purpose of the Study:

  • Characterize the microbial community in a salt-saturated brine from a salt cavern.
  • Assess microbial activity and potential risks to hydrogen storage.

Main Methods:

  • Analysis of salt cavern brine composition (sulphate, carbon).
  • 16S rRNA gene sequencing for microbial community analysis.
  • Growth experiments under various conditions (temperature, salt concentration, oxygen availability).

Main Results:

  • The brine is salt-saturated with high sulphate and low carbon content.
  • A halophilic microbial community (Bacteria and Archaea) was identified, including known genera and unknown sequences.
  • Microbial activity, including fermentation and sulphate reduction, was observed, with some microbes resistant to sterilization and active at high temperatures.

Conclusions:

  • Artificial salt caverns host extreme environments with diverse microbial life.
  • Potential hydrogen-consuming microbes present a risk for hydrogen storage integrity.
  • Further research is needed to understand and mitigate microbial impacts on hydrogen storage.
