6 FAQs about [An ice-like solid that contains both methane and water]
What is methane hydrate?
Methane hydrate is energy-dense: at atmospheric pressure, each unit of frozen methane hydrate can produce 164 units of natural gas. Their abundance in nature means that methane hydrates represent one of the largest known unconventional energy sources – and a much cleaner alternative to crude oil or coal.
What are gas hydrates?
Gas hydrates are ice-like crystalline substances occurring in nature where a solid water lattice accommodates gas molecules (primarily methane, the major component of natural gas) in a cage-like structure, also known as clathrate.
What is methane hydrate Subhamoy Bhattacharya?
Subhamoy Bhattacharya 7.1.1 What is methane hydrate? Methane hydrate (MH) is a solid compound in which a large amount of methane gas molecules (CH4) are caged within a crystalline structure of water, as illustrated in Fig. 7.1, under low temperature and high pressure, forming a solid similar to ice .
How is a methane hydrate created?
A methane hydrate is created when water molecules form a lattice structure around a methane molecule, without actually bonding to it. Image courtesy of NOAA Ocean Exploration. Download image (jpg, 98.6 KB). These relatively stable, ice-like substances are created in deep-ocean sediments and conditions of low temperature and high pressure.
How do ice hydrates melt?
We also expect to find moderately high concentrations deeper in the Earth. As sediments sink, the icy hydrates they carry melt, releasing their gas. This gas bubbles back up to form more gas hydrates just above the boundary, where they melt.
How is methane gas formed?
Methane gas is primarily formed by microorganisms that live in the deep sediment layers and slowly convert organic substances to methane. Methane hydrates are only stable under pressures in excess of 35 bar and at the low temperatures of the bottom waters of the oceans and the deep seabed, which almost uniformly range from 0 to 4°C.
