WebJul 27, 2024 Ā· Black, brown and grey hydrogen. Grey hydrogen is the most common form and is generated from natural gas, or methane, through a process called ā€œsteam reformingā€. This process generates just a smaller amount of emissions than black or brown hydrogen, which uses black (bituminous) or brown (lignite) coal in the hydrogen-making process. WebThere are two basic types of commercial helium deposits: natural gas produced primarily for the hydrocarbon content, typically containing less than 3 percent helium; and gas with little or no hydrocarbons, produced solely for the helium, which typically makes up between 5 and 10 percent of the gas. fiction for teen boys https://60minutesofart.com
