Carbon capture is a concept focused on the capture of carbon dioxide emissions produced by manufacturing, vehicles, and food production, among other industries.

Hydrogen is currently already an important resource for industry, used for things such as artificial fertiliser, but is still mainly made from natural gas in a process that releases carbon dioxide. The hydrogen produced is called ‘grey hydrogen’.

Power-to-gas (often abbreviated P2G) is a technology that uses electrical power to produce a gaseous fuel. When using surplus power from wind generation, the concept is sometimes called windgas.
