Gas hydrates have received considerable attention due to their important role in flow
assurance for the oil and gas industry, their extensive natural occurrence on Earth and …

This study provides a critical review of Underground Hydrogen Storage (UHS), emphasizing
its potential as a viable energy storage option despite several associated challenges. These …

Expectations for energy storage are high but large-scale underground hydrogen storage in
porous media (UHSP) remains largely untested. This article identifies and discusses the …

The origin of natural gases, in particular those containing methane (CH 4 or C 1), ethane (C
2 H 6 or C 2), propane (C 3 H 8 or C 3) and carbon dioxide (CO 2), is commonly interpreted …

The global geographic distribution of subseafloor sedimentary microbes and the cause (s) of
that distribution are largely unexplored. Here, we show that total microbial cell abundance in …

The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

For life to have emerged from CO2, rocks, and water on the early Earth, a sustained source
of chemically transducible energy was essential. The serpentinization process is emerging …

The seabed is a diverse environment that ranges from the desert-like deep seafloor to the
rich oases that are present at seeps, vents, and food falls such as whales, wood or kelp. As …

A general review of the sub-seafloor biosphere is presented. This includes an update and
assessment of prokaryotic cell distributions within marine sediments, current deepest 1922 …

Coal bed and shale gas can be of thermogenic, microbial or of mixed origin with the
distinction made primarily on the basis of the molecular and stable isotope compositions of …
