Carbon capture and storage (CCS)

Carbon capture and storage (CCS)

Carbon capture and storage (CCS) describes a suite of technologies that capture waste CO2, usually from large point sources, transport it to a storage site, and deposit it where it will not enter the atmosphere.

Hydrogen (H2)-based ironmaking

Hydrogen (H2)-based ironmaking

There are three main sources of hydrogen. ‘Green’ hydrogen is produced by combining renewable energy with electrolysis, ‘blue’ hydrogen is produced from fossil fuels in a facility equipped with carbon capture and storage (CCS), and ‘grey’ hydrogen comes from unabated fossil fuel.
