Quebec’s Green Hydrogen and Waste Biofuel Revolution
A pioneering Canadian project turns hydroelectricity and landfill waste into clean hydrogen and advanced biofuels, charting a new path for sustainable energy.
Quebec Sets a New Standard in Green Hydrogen and Biofuel
In the face of a rapidly intensifying climate crisis, governments and industries around the world are seeking scalable, reliable, and innovative solutions to reduce greenhouse gas emissions. Quebec’s landmark initiative—the Recyclage Carbone Varennes (RCV) project—offers a striking new model for how renewable electricity and residual waste can together spearhead the clean energy transition. Located in Varennes, near Montreal, this project is poised to become one of the largest and most advanced commercial-scale facilities globally to combine green hydrogen and waste-to-biofuel technologies.
Let’s explore the vision, technology, partnerships, challenges, and environmental implications of this transformative undertaking.
The Road to Green Hydrogen: What Sets the Quebec Model Apart
Green hydrogen—produced through electrolysis powered by renewable energy—promises a zero-emission fuel that could displace fossil-derived hydrogen and traditional fuels in industry, transport, and beyond. Canada produces substantial quantities of hydrogen today, but nearly all comes from fossil sources, emitting significant greenhouse gases in the process. The RCV project aims to break this pattern by:
- Utilizing Quebec’s vast hydroelectric resources to power the electrolysis process, ensuring the hydrogen is genuinely carbon-free.
- Coupling hydrogen production directly with a biofuel plant that converts non-recyclable waste into methanol and other valuable chemicals, closing energy and material loops.
- Deploying one of the world’s most powerful electrolyzers, designed by thyssenkrupp, with a planned capacity of 88 megawatts—capable of producing approximately 11,100 metric tonnes of green hydrogen annually.
This integration allows for shared infrastructure and operational synergy. The proximity of clean electricity, advanced electrolysis, and cutting-edge chemical conversion makes Quebec’s model unique.
Strategic Alliances and Investment: Keeping the Project on Track
The Recyclage Carbone Varennes project is supported by a complex, multinational partnership that underscores its monumental scope and ambition. Key stakeholders include:
- Quebec Ministry of Economy and Innovation, providing significant funding (over $360 million CAD across loans and preferred shares).
- Major industrial partners such as Suncor Energy, Shell, and Switzerland-based Proman AG, bringing expertise and capital.
- Cutting-edge technology suppliers like thyssenkrupp Uhde Chlorine Engineers, a world leader in large-scale water electrolysis.
- Enerkem, a Montreal-based innovator in waste-to-fuel technology, whose chemical processes convert non-recyclable waste into clean chemicals and fuels.
The project also expects further support from the federal government, especially via the Canada Infrastructure Bank, highlighting its significance in the nation’s efforts to become a leader in clean energy and climate action.
From Water and Waste to Clean Fuels: The Core Technologies
Electrolysis—the process of splitting water into hydrogen and oxygen using electricity—is at the core of Quebec’s green hydrogen ambition. In the Varennes facility:
- Hydropower from Quebec’s grid supplies completely renewable electricity.
- An 88 MW electrolyzer splits water into hydrogen and oxygen at large scale.
- The resulting hydrogen is channeled directly into a neighboring waste-to-biofuel plant, also built and operated with strong industrial partnerships.
- Oxygen, a by-product, is also utilized in the same biofuel production process, ensuring minimal waste and maximum efficiency.
What others are reading
The integration of these systems ensures that both energy flows (from hydropower) and material flows (from landfill-bound waste) are used as efficiently as possible. This synergy is rare and represents a high degree of industrial symbiosis.
The Waste-to-Biofuel Revolution: Turning Trash into Value
At the heart of the project’s second phase is Enerkem’s proprietary chemical process, which can convert non-recyclable urban waste—such as plastics and other refuse that would otherwise end up in landfills—into valuable chemicals, most notably biomethanol.
- Biomethanol can replace fossil methanol in the production of paints, plastics, textiles, building materials, and transportation fuels.
- The RCV plant aims to produce approximately 135 million liters of biomethanol annually, a major leap compared to the small volumes of biomethanol produced globally today (just 200 million liters annually versus nearly 140 billion liters of conventional methanol).
- By capturing non-recyclable waste and converting it into new chemicals, the facility sharply reduces the region’s landfill burden and provides a carbon sink for difficult-to-recycle materials.
The Benefits: Environmental and Economic Impacts
This project brings multi-layered benefits to Quebec and far beyond:
- Significant reduction in greenhouse gas emissions compared to conventional hydrogen and methanol production.
- Diverting thousands of tons of urban waste from Quebec’s landfills, boosting landfill capacity and reducing future landfill-related pollutants.
- Establishing Quebec as a North American leader in clean hydrogen, biofuel production, and large-scale industrial decarbonization.
- Job creation and economic stimulation in advanced manufacturing, clean tech, engineering, and local waste management.
- Positioning Canada for climate leadership via innovation, exportable technical expertise, and scalable solutions.
Challenges: Keeping Ambition Aligned with Reality
Despite the strong outlook, several hurdles remain for the RCV project and similar first-of-their-kind ventures:
- Financial complexity: The $1.2 billion (CAD) cost is significant, and large public and private investments will only be recouped if the project performs as intended and if market demand grows for green hydrogen and biomethanol.
- Technical integration: Coordinating advanced electrolysis, waste conversion, and chemical processing at scale requires robust engineering and strong operational management.
- Market development: While hydrogen is touted as a future clean fuel, transportation and industrial users must adapt infrastructure and secure offtake agreements to absorb the planned production.
- Policy clarity: To sustain green hydrogen and advanced biofuel markets, continued support from provincial and federal governments will be necessary, especially through incentives and infrastructure investment.
Although Hydro-Québec departed from direct operational leadership (citing strategic business priorities), the project is moving forward thanks to the combined efforts of its remaining industry and government partners.

The Broader Picture: Why This Matters for the Energy Transition
The Quebec project is being closely watched as a potential template for large-scale, integrated green hydrogen and biofuel production globally. It is helping address several key issues:
- Decarbonizing industrial sectors—heavy industries, chemical manufacturers, and transport can switch to green hydrogen and biofuels, slashing emissions where electrification alone is not feasible.
- Durable waste management solutions—transforming previously landfilled urban waste into a resource, tackling two major environmental challenges simultaneously.
- Driving down costs through scaling—as the technology and business case for large-scale green hydrogen and waste-to-fuel become proven, global adoption becomes easier and less expensive.
- Enabling grid stability—hydroelectricity can be supplemented with hydrogen production during periods of surplus, making Quebec’s clean grid more flexible and resilient.
Frequently Asked Questions (FAQ)
