Reaching our net-zero goals with hydrogen

As the world transitions towards a clean energy future, the urgency of achieving net-zero emissions has never been greater. Clean hydrogen can allow energy to be effectively and efficiently stored, transported, and used in innovative ways to reduce greenhouse gas (GHG) emissions, and help the world reach its climate target goals by 2050. By working closely with key decision-makers, Enbridge Gas can put hydrogen into action to help achieve climate commitments in areas such as municipal, agricultural, industrial, transportation and more.

How hydrogen supports a clean energy future


Hydrogen can be safely blended into Ontario’s natural gas supply to offset its carbon footprint and lower emissions.


Electricity can be converted into hydrogen and, like natural gas, stored year-round on a large scale for reliability and stability.

Connecting system

Enabling the natural gas system and electricity grid to work together, hydrogen supports resiliency and helps balance Ontario’s energy supply and demand.

Replacing higher-carbon fuels

Clean hydrogen can replace carbon-based fuels used for heavy-duty transportation and industrial processes.

What makes hydrogen a clean energy alternative? It comes down to how it’s made

Power-to-Gas (PtG) is a process in which electrical energy is converted to hydrogen through the electrolysis of water. If only renewable sources of electricity are used, the hydrogen produced is called renewable. If hydrogen is produced from a mix of renewables and other sources, it’s considered low carbon.*

Most of today’s hydrogen is created using steam methane reforming (SMR), a process that separates hydrogen from methane. If the carbon emissions are captured (greater than 90 percent) and safely stored, the hydrogen produced is considered low carbon, or blue.

Like electricity, hydrogen is a flexible energy carrier. Unlike electricity, it can be used to efficiently store electrical energy, and turned back into electricity when required.

Low-carbon and renewable hydrogen

While describing hydrogen types using colour is common, the terminology is not standardized and can cause confusion. This is why the industry is moving towards a simpler classification, using terms such as low-carbon and renewable hydrogen.

We’re innovating to support Ontario’s energy transition

As the global population grows, it’s expected that energy usage will increase by 50 percent over the next 30 years†; getting to net zero has never been more important for the environment. Demand for clean hydrogen is expected to reach 500 – 800 million tonnes worldwide by 2050.‡ Enbridge Gas is supporting this transition to clean energy through innovative solutions and collaboration with governments and partners to help achieve our climate goals.

North America’s first utility-scale power-to-gas facility

Located in Markham, Ontario, Canada, our utility-scale PtG facility converts surplus electrical energy from renewable sources into hydrogen, which can then be blended into the natural gas system to help balance Ontario’s electricity supply and demand.

Pathways to Net Zero

Enbridge Gas engaged a consultant, Guidehouse, to assess the feasibility of two pathways to net zero. The study finds that, compared to an electrification pathway, a diversified pathway is the most practical way to achieve net-zero emissions in Ontario.

Frequently asked questions

Non-toxic and non-poisonous, hydrogen can be safely blended into the natural gas system to green Ontario’s supply. Natural gas is still one of the safest fuels used today and Enbridge Gas has a long history of providing safe and reliable service to our customers.

Some areas in Europe blend up to 20 percent hydrogen. Enbridge Gas is beginning with up to two percent by volume as a pilot project.

In a measured amount, hydrogen blends seamlessly into the existing natural gas system, with no changes to reliability or the quality of service. You’ll continue to be able to heat your home and water safely. The amount at which Enbridge Gas is blending hydrogen (up to two percent by volume) will have no adverse effects on your appliances.

Approximately nine to twelve litres of water is used to produce one kilogram of hydrogen and about eight kilograms of oxygen.

Ontario’s Made-in-Ontario Environment Plan, released November 2018, commits the province to reducing greenhouse gas emissions to 30 percent below 2005 levels by 2030, in line with Canada’s 2030 target. As part of the plan, the province has developed a low-carbon hydrogen strategy. The strategy establishes a vision for a new hydrogen economy that will address climate change and air quality while creating opportunities for industry to grow. Enbridge Gas, along with other participants across Canada, contributed to developing this strategy.

*Low carbon hydrogen is hydrogen produced from an electricity grid with an emission factor less than 36 (g CO2eq/kWh).  In Ontario, hydrogen made from the electrical grid can be termed low carbon as it meets this threshold. In 2018 the Ontario electrical grid’s annual average emission factor value (AEF) was 31 (g CO2eq/kWh).
