message_ix_models.project.navigate.wp2.util.limit_h2(scen: Scenario, type: str = 'green') → None[source]

Limit hydrogen technology activities.

Entries are added to scen for bound_activity_up for technologies:

h2_bio, h2_coal, h2_smr (“grey hydrogen” technologies), plus
if type is “green” (the default and only allowed value): h2_coal_ccs and h2_smr_ccs (“blue hydrogen” technologies).

The following “green hydrogen” technologies are not constrained: h2_bio_ccs and h2_elec.

Parameters:: type (str, optional) – Type of hydrogen. ValueError is raised for any value other than “green”, the default.
