Web27 jul. 2024 · Black, brown and grey hydrogen. Grey hydrogen is the most common form and is generated from natural gas, or methane, through a process called “steam reforming”. 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.

A neon light contains a tiny amount of neon gas under low pressure. Electricity provides energy to strip electrons away from neon atoms, ionizing them. Ions are attracted to terminals of the lamp, completing the electric circuit. Light is produced when neon atoms gain enough energy to become excited.
