Check out the latest research paper from Theodore Street, P.Eng, and the Dalhousie University Hydrogen Applications Research Lab. The Lab has been conducting interesting and important research on the safety and performance of natural gas appliances that use a blend of hydrogen and natural gas.
Excited to share our latest work published in the International Journal of Hydrogen Energy! We measured methane and hydrogen leakage from residential appliances and piping systems using natural gas and both 5% and 20% hydrogen blends. Key takeaways: - No significant safety concerns were observed, and blending hydrogen into natural gas reduced methane leakage. - HBNG mixtures did not leak significantly more than natural gas, although some variations were observed due to the sampling methodology and low leakage rates. - Fugitive appliance emissions are not constant over time- they are highest immediately after appliance shutdown – a key consideration for accurate emissions measurements. This work strengthens the case for hydrogen blending as a near-term climate solution—reducing greenhouse gas emissions without compromising appliance safety or performance. I’m very grateful for my coauthors Amel Ali, Cash Bertolo, and the supervision of Dr. Michael Pegg—this was Amel and Cash’s first academic paper, and they did a phenomenal job! #Hydrogen #CleanEnergy #EmissionsReduction #HydrogenBlending #NaturalGas #DalhousieUniversity
