The ice-core methane clathrate record is a primary source of data for global warming research, along with oxygen and carbon dioxide. Methane clathrates used to be considered as a potential source of abrupt climate change , following the clathrate gun hypothesis .
Methane clathrate, also known commonly as methane hydrate, is a form of water ice that contains a large amount of methane within its crystal structure. Potentially large deposits of methane clathrate have been found under sediments on the ocean floors of the Earth, although the estimates of total resource size given by various experts differ by ...
Methane clathrate block embedded in the sediment of hydrate ridge, off Oregon, USA. Clathrate hydrates, or gas hydrates, clathrates, or hydrates, are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside "cages" of hydrogen bonded, frozen water molecules.
The Japanese drilling project, part of the “Methane Hydrate Research and Development (R&D) Program”, [4] is located in the Nankai Trough region along the southeastern margin of Japan. The production research well project was developed in this region after field surveys completed by the Japanese government in 1995 revealed the existence of a ...
The free gas zone is a zone of freed methane in a hydrate formation, beneath the hydrate stability zone. It can influence the rate of methane output at a ridge or ridge region. A large free gas zone makes more methane available to be released into the open ocean, and, thus, can likely be more influential on climate change than a smaller one. [11]
WASHINGTON (Reuters) - Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best ...
A part of his research is also focused on energy recovery from methane hydrate, which is considered as a huge energy resource for natural gas. [31] His research group has been working on process innovation and process development to scale-up clathrate hydrate as a technology enabler for clean energy and sustainable applications. [32]
Clathrate compounds with formula A 8 B 16 X 30, where A is an alkaline earth metal, B is a group III element, and X is an element from group IV have been explored for thermoelectric devices. Thermoelectric materials follow a design strategy called the phonon glass electron crystal concept.
