The Bureau de normalisation du Québec (BNQ) and CSA Group are spearheading a public review on a binational draft standard for measuring the environmental impact of hydrogen production in Canada and the United States. The standard, CAN/BNQ 1789-200 A, aims to define a harmonized methodology for reporting on the carbon intensity of hydrogen production, emphasizing the types of feedstock, energy sources, water consumption, supply chain geography, and supply modes. By promoting low carbon intensity energy production methods and sources, the standard seeks to enhance market recognition for producers with low carbon projects both domestically and internationally. The initiative, funded by the Quebec Ministry of Economy, Innovation and Energy, with support from the Standards Council of Canada, intends to provide consistency in evaluating hydrogen to contribute to energy production decarbonisation and industrial process decarbonisation. Informal systems currently used for describing hydrogen production based on carbon intensity lack consensus, hence the need for a comprehensive standard. Isabelle Landry, Principal Director at BNQ, emphasized the importance of ensuring the draft standard's alignment with market needs and decarbonisation goals. Stakeholders interested in providing feedback on the draft standard have until July 30, 2024, to submit their comments and proposals. The comments will be reviewed by the standardization committee, and necessary adjustments will be made for the publication of the Canadian standard in spring 2025. This public review process allows for technical justifications and clause-specific feedback to refine the standard. The BNQ, as a key player in standardization and certification in Quebec, is leading this effort in collaboration with the CSA Group to advance environmental impact measurement in hydrogen production. The new standard's implementation is expected to improve market clarity, support sustainable energy practices, and drive the transition towards low carbon hydrogen production in Canada and globally.
