This guidance covers large-scale industrial plants:

• producing hydrogen using methane (for example, from natural gas) or refinery fuel gas

• capturing the CO₂ produced within the process, carbon capture (CC), or using post-combustion carbon capture (PCC) to make it ready for permanent geological storage this is known as carbon capture and storage or sequestration (CCS)

It is for:

• operators when designing their plants and preparing their application for an environmental permit

• regulatory staff when determining environmental permit applications

• any other organisation or members of the public who want to understand how the environmental regulations and standards are being applied

The guidance covers both new plants and retrofits to existing plants.

The guidance does not cover downstream permanent geological storage or using the captured CO₂.

There is also a review of emerging techniques that summarises the available evidence to support this guidance.
