"To continue close cooperation with IPHE due to IPHE’s large, global influence, pragmatic approach to carbon footprint methodology development and input to ISO’s standard development initiative."
IPHE is an intergovernmental organization that is developing a global methodology for determining GHG emissions from hydrogen and ammonia production. IPHE is not developing a certification scheme, but its methodology will be incorporated by many certification schemes (eg, Australian Government's Guarantee of Origin, UK Government's (BEIS) scheme, Green Hydrogen Standard, CertifHy, etc).
The AEA provided feedback to IPHE on its draft (yet to be published) ammonia as a hydrogen carrier methodology in February 2022 (
