A harmonized methodology for reporting the production pathway and carbon intensity of hydrogen
This is the first edition of CSA/ANSI R124/CAN/BNQ 1789-200, A harmonized methodology for reporting the production pathway and carbon intensity of hydrogen. CSA Group and the Bureau de normalisation du Québec (BNQ) acknowledge that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan), the Gouvernement du Québec, and Standards Council of Canada (SCC). This Standard was prepared by the Technical Committee on Carbon Intensity of Hydrogen, under the jurisdiction of the Strategic Steering Committee on Organizational Management and Sustainability, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group and the Bureau de normalisation du Québec. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.
The following inclusions apply
The following exclusions apply
Note: Protocols and standards exist for this purpose and are referenced in this Standard (see Clause 5.5.2). c) This Standard does not cover information related to the additional carbon emission resulting from conditioning and transporting hydrogen from the producer to the end user. d) This Standard does not apply to hydrogen obtained by mixing hydrogen produced either in multiple sites or via multiple production pathways. e) This Standard is not designed to be applied to syngas or blends of hydrogen and other fuels
In cases of conflict between this Standard and federal, provincial, state, territorial, or local regulations, governmental regulations take precedence.
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
The values given in SI units are the units of record for the purposes of this Standard.
