In 2023 Pironon and de Donato announced the discovery of a deposit they estimated to be some 46 million to 260 million metric tons (several years worth of 2020s production). [18] In 2024, a natural deposit of helium and hydrogen was discovered in Rukwa, Tanzania., [19] as well in Bulqizë, Albania. [20]
This list is based on the CIA World Factbook (when no citation is given). [1] or other authoritative third-party sources (as cited). Based on data from EIA, at the start of 2021, proven gas reserves were dominated by three countries: Iran, Russia, and Qatar. There is some disagreement on which country has the largest proven gas reserves.
Countries by natural gas proven reserves (2014), based on data from The World Factbook. This article includes a chart representing proven reserves, production, consumption, exports and imports of natural gas by country. Below the numbers there is specified which position a country holds by the corresponding parameter.
Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop. In this way, Canada's proven reserves increased suddenly in 2003 when the oil sands of Alberta were seen to be economically viable.
A German case study on storage of hydrogen in salt caverns found that if the German power surplus (7% of total variable renewable generation by 2025 and 20% by 2050) would be converted to hydrogen and stored underground, these quantities would require some 15 caverns of 500,000 cubic metres each by 2025 and some 60 caverns by 2050 ...
Natural gas deposits are also the main source of helium. Heavy crude oil, which is much more viscous than conventional crude oil, and oil sands, where bitumen is found mixed with sand and clay, began to become more important as sources of fossil fuel in the early 2000s. [33]
Russia is the world leader and contributed 30 percent of total global APG flared in 2009. [13] The World Bank estimates that over 150 billion cubic metres of natural gas are flared or vented annually. Flared natural gas is worth approximately 30.6 billion dollars and equivalent to 25 percent of the United States' yearly gas consumption or 30 ...
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
