20 quadrillion cubic meters
It is estimated that vast amounts of methane, potentially around 1,000 to 10,000 gigatons, may be locked up in sediments containing gas hydrates. These hydrates are found primarily in marine sediments and permafrost regions, where specific temperature and pressure conditions allow methane to form solid hydrates. This significant reservoir of methane has implications for both energy resources and climate change, as the release of methane could contribute to greenhouse gas emissions.
20 quadrillion cubic meters
It is estimated that there may be more methane locked up in sediments containing gas hydrates than all other fossil fuel reserves combined. The total global potential of methane in gas hydrates is uncertain but could be in the range of hundreds of trillion cubic meters. Unlocking this methane poses challenges due to technical, environmental, and economic factors.
Psst! Come in close for this one. There is a secret here. Natural gas, that stuff the utility company pumps into your home, with which you heat the house, water, and cook. That is primarily methane, essentially the same stuff as the stink that comes from manure piles, and is locked in the sea bed. That stuff that the Greenies were complaining about a few years ago was adding to global warming (cow flatuence). In short, yes, methane is a very renewable resource.
