Hydrogen is one of the most abundant elements in the universe, and is found in water (H₂O), which is why one of its sources of production is electrolysis (Evolugen & Enbridge Gaz are working together on this projects). By running electricity through water, the hydrogen can be separated from the oxygen to create gaseous hydrogen (H₂), which is a very light, odourless and colourless gas. The hydrogen can then be transported through pipelines or by truck for use in industrial processes as a fuel or fuel cells, or mixed into the natural gas system.

Because it is produced through electrolysis, its combustion emits only water vapour, which is why hydrogen can be rated as “clean”.

Hydrogen is considered an energy vector because, once processed, it can be stored, transported and used.

This is the initial phase of a long-term global project that involves establishing a regional energy ecosystem in the Outaouais.

This initial phase is focused on the production, distribution and consumption of clean hydrogen.

The project involves capturing gaseous hydrogen as a sub-product at the Erco plant in Gatineau, and distributing it through a pipeline extending over some 20 kilometres that will be built between the Buckingham and airport sectors.

There are hydrogen pipelines in Canada and the United States. In Quebec, there are facilities that produce or use hydrogen. What is new about this project is the distribution aspect, which will enable customers to connect directly to the system, as is the case with natural gas.

The different colours attributed to hydrogen refer to the ways it is produced.

• Green hydrogen is produced through electrolysis, using electricity from renewable sources (hydro or wind).
• Blue hydrogen is produced through the gasification of natural gas or coal, including a device for capturing and storing CO2.
• Gray hydrogen is produced by separating the hydrogen and carbon atoms in natural gas using water vapour or heat.

Enbridge Gaz is a progressive company that is always looking for ways to reduce its carbon footprint and to minimize greenhouse gas emissions. By assessing the option of blending in hydrogen, Enbridge Gaz is positioning itself as a leader in innovative technologies, and seeking to live up to its commitment to protect the environment.

As with any fuel, appropriate safety procedures are required. As with natural gas, Enbridge Gaz is committed to providing energy reliably and safely, and to having in place work practices that ensure the public’s and workers’ safety.
In its normal state, hydrogen is gaseous, colourless, odourless and non toxic. The hydrogen molecule is so light that it immediately disperses into the atmosphere.

This is why, in the event of an accidental leak, gaseous hydrogen vaporizes so fast that there is no risk of fire. There are no puddles on the ground, and no contamination of groundwater.

Water is the only result of hydrogen combustion. When it is released into the air, all that remains is pure water.

Like natural gas, hydrogen is odourless. Mercaptan is an odorant used to give natural gas its distinctive odour for ease of detection in businesses and homes where it is used. In the case of hydrogen, a study is currently underway to determine what measures will be used for optimal prevention and detection of leaks.

As with natural gas, Enbridge Gaz will have a 24/7 emergency service that will be able to respond to any type of emergency and work in partnership with the municipal fire department on prevention and training. In the event of a leak, Enbridge Gaz will respond promptly to restore safety as quickly as possible.

The risk of incidents from hydrogen pipelines is no greater than from natural gas pipelines of similar diameter and pressure.

The purpose of this project is to supply hydrogen to refuelling stations, the heavy transport sector, and customers outside the region.

The green hydrogen that is the focus of our project is produced locally, here in the Outaouais, from water and clean electricity. Enbridge Gaz will buy that hydrogen from producers, and could deliver it to industrial or commercial customers, as well as to the natural gas system. Once injected into that natural gas system, the hydrogen would blend with the traditional natural gas in the distribution system, and power the appliances connected to the system the same way as traditional natural gas. This would directly reduce those appliances’ emissions, as well as those of customers.

Who is the hydrogen project directed at?

Once the construction work has been completed and the service can start up, that hydrogen will initially supply industries and the heavy transport sector.

• Clean and ecological: hydrogen enables customers to reduce their carbon footprint and to take action.
• No change in equipment required! This energy source is simple, and is transported and used the same way as natural gas, the difference being that it is green!
• Less carbon dioxide emissions

All of the safety measures applied for natural gas continue to be applied.

We expect the hydrogen pipeline to become operational in 2026. Industrial customers interested in learning more can contact us now to start the connection process.

We expect the hydrogen pipeline to become operational in 2026. Enbridge Gaz does not have any residential solutions for hydrogen at this time but may have some in the future.

Customers directly connected to the hydrogen system will be billed monthly, as with natural gas.

Depending on its use, this project would make it possible to prevent the release of approximately 15,000 tonnes of GHG annually, and would generate significant economic and local benefits, including new jobs and incremental property tax revenues.

• Sustainable energy that helps reduce greenhouse gas emissions
• Replacement of a fossil fuel by a renewable energy

Green hydrogen is produced through renewable electricity and water, and replaces the use of carbon-based energy in sectors that are sometimes difficult to electrify, such as heavy transport and industry. Thus, its use helps reduce carbon emissions from traditional fossil energies, and thereby help decarbonize the territory.

The distribution of hydrogen through pipelines is not subject to MELCCFP requirements.

Environmental studies have been done to limit the project’s impact on the environment. They are based on available existing data (Centre de données sur le patrimoine naturel du Québec, Centre d’expertise hydrique du Québec, Géobase du réseau hydrographique du Québec, Ducks Unlimited Canada, MELCCFP, MRC Les Collines-de-l’Outaouais, Ville de Gatineau, and Municipalité de l’Ange-Gardien). Inventories have also been drawn up (waterways and fish habitats, vegetation and wetlands, species of conservation concern (wildlife and vegetation), and invasive exotic species).

Hydrogen installations are not currently regulated by the Régie de l’Énergie.

Enbridge Gaz is committed to environmental stewardship, and always conducts itself responsibility in regard to the environment. Enbridge Gaz is committed to protecting the environment, and recognizes that preventing pollution, protecting biodiversity and conserving resources are key factors in a sustainable environment. Every employee is considered responsible, and must contribute to a safe work environment. They must promote safe occupational attitudes and conduct themselves responsibly in regard to the environment.

The water molecule (H2O) consists of two hydrogen atoms (H2) and one oxygen atom (O). Electrolysis uses electricity to separate molecules into atoms. The hydrogen gas is then added to our natural gas at a regulating station. Once the blend of hydrogen and natural gas passes through the station, it enters the distribution pipeline network where it eventually travels to customers.

Yes, since 2019, Enbridge has been operating a natural gas system with 2% hydrogen. Many other gas distributors in Canada and elsewhere are also currently considering this option.

The CSA Group has determined that 5% hydrogen in natural gas has no impact on the performance of natural gas appliances. Studies are underway to determine the impact of a higher ratio. At no point has the CSA Group indicated that this limit was related to users’ safety.

We expect to build the pipeline along the existing right of way next to the road, so we do not anticipate any significant environmental disruptions. The environmental assessment (currently underway) will yield additional information for protecting the environment.

There are supply chain delays, and our partners are currently completing the engineering study stages to confirm the amount of hydrogen that can be injected into the distribution system. The supply has to be secured.

Several corridors have been considered in terms of environmental, social and technical feasibility. The ones proposed during the public participation period are the ones that we deemed the most viable.

In its February 2021 announcement, the federal government confirmed a $1.5 billion investment into a fund for low-carbon content and zero emission fuels.

On February 1, 2024, the federal government announced more than $3.3 million towards a $7.3 million clean fuel project for a feasibility study on blending hydrogen, more specifically to assess the development of an electrolysis facility to decarbonize Enbridge Gaz’s natural gas distribution system by injecting low-carbon hydrogen into it.

This project is funded by Enbridge Gaz, with financial support from Natural Resources Canada.
