Hydrogen Blending – Not a serious decarbonization pathway

The document argues that hydrogen blending is neither an economical nor an effective way to decarbonize natural gas users, noting that low-concentration blends provide insignificant emissions reductions and high-concentration blends require significant infrastructure upgrades.

• The ability of current natural gas infrastructure to handle low-concentration hydrogen blends (1% to 10% volume) varies and requires case-by-case evaluation, while blends exceeding 20% volume necessitate significant network upgrades.
• Hydrogen blending is an ineffective decarbonization tool because emissions reductions are insignificant at 20% volume, and the associated carbon abatement costs can be prohibitive, potentially exceeding $300 per tonne of CO2.
• Blending hydrogen into the gas grid is considered an inefficient use of a resource that should instead be used to directly decarbonize sectors without other alternatives, such as the industrial sector.
