T-5B4-A-7 - Gasification of carbon for hydrogen production

Definition

This emission source is defined by the IPCC in TBD.

Sustainability Category: Red

This activity significantly contributes to greenhouse gas emissions and undermines climate mitigation efforts. The activity should be phased out or fundamentally transformed, with financing directed toward decommissioning, replacement with sustainable alternatives, or radical decarbonization where elimination is not immediately feasible.

Transition Elements

This activity has the following mitigation options modelled as transition elements:

• T-5B4-TE-2 - Biomass in carbon gasification for hydrogen production
• T-5B4-TE-6 - Shift to electrolysis of water for hydrogen production

Activity Model

This emission source is modelled with Gasification as:
