Hydrogen Blending: Paving the Way to a Cleaner Future for Canada’s Gas Industry
The future of energy is being redefined by innovation and change, and one innovation stands out as a key enabler of decarbonization in the natural gas sector: hydrogen blending. As Canada works toward meeting its climate goals and transitioning to a low-carbon economy, hydrogen blending offers a practical and scalable path forward for natural gas utilities and pipeline operators.
But what exactly is hydrogen blending, and why is it such a game changer for the natural gas industry?
What is Hydrogen Blending?
Hydrogen blending refers to the process of injecting hydrogen gas (H₂) into existing natural gas pipelines and distribution networks. This blend—typically in concentrations ranging from 5% to 20% hydrogen—can be combusted in the same manner as natural gas to deliver energy for heating, power generation, and industrial applications.
The key advantage? Hydrogen, when burned, produces zero carbon dioxide emissions. This makes it an attractive option for reducing the carbon intensity of traditional natural gas without requiring a complete system overhaul.

Why Hydrogen Blending Matters to Canada’s Gas Industry
Canada’s energy sector is under increasing pressure to decarbonize, and utilities are actively exploring pathways that can lower emissions without sacrificing reliability, safety, or affordability. Hydrogen blending is uniquely positioned to address these goals.
Here’s why this technology matters:
Lower Emissions, Greater Impact
By replacing a portion of methane (CH₄) in the gas stream with hydrogen, utilities can cut greenhouse gas (GHG) emissions while continuing to provide dependable energy to homes and businesses.
On top of reduced emissions, natural gas blended with hydrogen leverages the significant investments utility companies have already made in pipeline infrastructure—saving on both upgrade costs and the additional emissions that would be generated from building entirely new systems.
According to the Canadian Gas Association (CGA), blending up to 20% hydrogen by volume can reduce CO₂ emissions from natural gas use by approximately 7%, depending on system configuration and fuel source.

Compatibility with Existing Infrastructure
One of the most compelling aspects of hydrogen blending is its compatibility with the infrastructure already in place. Studies and pilot projects across Canada, Europe, and the U.S. have shown that modern polyethylene and steel distribution pipelines can safely transport hydrogen blends at low concentrations with minimal modifications.
For instance, Enbridge Gas and Cummins launched a pilot project in Markham, Ontario, to blend up to 2% hydrogen into the local gas distribution system—demonstrating the feasibility and safety of hydrogen blending within Canada’s regulatory framework.
In Alberta, ATCO is piloting a similar project in Fort Saskatchewan, blending up to 5% hydrogen into a residential gas network. The initiative showcases how hydrogen can be integrated into existing infrastructure to reduce emissions and support provincial decarbonization goals.

Energy Diversification and Resilience
Hydrogen blending is not just a climate solution—it’s a strategic diversification move. Integrating low-carbon hydrogen into the gas grid adds resilience to Canada’s energy system by reducing dependence on a single fuel source. It also creates economic opportunities in hydrogen production, storage, and technology development.
Canada’s natural advantage in clean electricity, natural gas reserves, and carbon capture technologies positions it as a global leader in hydrogen development—especially for producing blue hydrogen (from natural gas with carbon capture) and green hydrogen (from electrolysis powered by renewables).
Bill 52: Turning Hydrogen Blending into a Real Business Opportunity
In April 2025, Alberta introduced Bill 52, a key legislative shift that allows gas utilities to recover the costs of hydrogen blending projects—but only from customers receiving the blended gas. This marks a major turning point: hydrogen blending is no longer limited to R&D and pilot programs. There is now a clear business case for utilities to invest, plan, and scale.
By formalizing cost recovery through the Alberta Utilities Commission, Bill 52 gives utilities the confidence to move beyond experimentation and begin treating hydrogen as a viable part of long-term decarbonization strategies.
