Submitted Comment Name Brent Hartman Affiliation CSA Group Subject Hydrogen Blends for Appliances Message Regarding the use of hydrogen blends in appliances, CSA Group’s standards Technical Committees have been provided access to a range of test data from a variety of sources, and upon careful review and analysis, agree that natural gas containing up to and including 5% of Hydrogen is covered by testing with Test Gas A. As such, no changes to our standards are required, and product certifications remain valid for these blend levels.
