Nova Scotia has conditionally approved what would become the province’s largest onshore wind project, advancing a renewable energy development that is central to Canada’s ambitions to establish a green hydrogen export industry.
The decision also highlights a broader challenge facing hydrogen developers: securing renewable electricity is increasingly achievable, while obtaining long term offtake agreements remains the critical hurdle for final investment decisions.
The Ocean Lake Wind Project, located in Guysborough County, received environmental approval from Nova Scotia’s Department of Environment and Climate Change following completion of its environmental assessment. Developed by EverWind Fuels in partnership with Membertou Development Corporation, the project will include up to 158 wind turbines with a planned installed capacity of approximately 1,264 MW.
Construction is expected to begin in 2029 and continue for approximately five years, with an operational life of around 35 years. The approval is conditional upon compliance with 61 environmental requirements covering noise limits, shadow flicker, protection of water resources, wildlife, vegetation, archaeological sites, and ongoing engagement with local communities and the Mi’kmaq of Nova Scotia.
Unlike many utility scale wind developments that supply electricity directly to the grid, Ocean Lake is designed primarily to power EverWind’s planned Point Tupper energy hub in Cape Breton, where renewable electricity will be used to produce green hydrogen and ammonia.
According to the provincial government, the wind farm would generate enough electricity to meet the equivalent annual consumption of approximately 404,000 homes while reducing Nova Scotia’s greenhouse gas emissions by an estimated 1.94 million metric tons per year. The province also noted that the project supports emissions reduction targets by supplying renewable electricity to new industrial activity without increasing overall provincial emissions.
For hydrogen developers, dedicated renewable generation has become increasingly important as electrolysis projects require large volumes of low carbon electricity to achieve competitive emissions intensity and satisfy international certification requirements.
Hydrogen export ambitions depend on market demand
Ocean Lake forms part of EverWind’s broader hydrogen development strategy centered on the Point Tupper facility.
The first phase of the project, expected to begin operations in 2028, carries an estimated capital cost of approximately $2 billion and is designed to produce around 200,000 metric tons of green ammonia annually. A second expansion phase would increase annual production by an additional 800,000 metric tons, with electricity from Ocean Lake and other planned wind farms intended to supply that larger facility.
The strategy reflects Canada’s effort to position Atlantic provinces as suppliers of renewable hydrogen derivatives to international markets, particularly Europe. Green ammonia offers a practical export pathway because it is easier to transport than hydrogen and can either be used directly as an industrial fuel or cracked back into hydrogen after import.
Germany and Canada signed a nonbinding hydrogen alliance in 2022 that identified green ammonia imports as a potential mechanism for reducing European dependence on fossil fuel imports. However, large scale commercial trade has yet to materialize, and no green hydrogen production has begun at Point Tupper.
Despite continued progress on permitting and project development, EverWind has consistently identified customer commitments as the primary requirement for advancing construction.
Company executives have previously stated that securing long term European buyers is essential for obtaining project financing. While preliminary work has begun at proposed wind farm sites, construction of the hydrogen production facility will not proceed until sufficient purchase agreements are in place.
This reflects a broader trend across the global green hydrogen sector. Numerous projects have secured land, environmental approvals, and renewable energy resources, but comparatively few have reached final investment decision because financial institutions continue to require firm offtake contracts before committing capital to multibillion dollar developments.
The Ocean Lake approval therefore represents an important regulatory milestone rather than a guarantee of project execution. It removes one significant permitting barrier while leaving commercial viability dependent on export demand, financing conditions, and the pace at which international hydrogen markets transition from policy commitments to binding purchasing agreements.
The project also reflects the growing role of Indigenous participation in Canada’s renewable energy sector.
Membertou Development Corporation, the economic development arm of the Membertou First Nation, is jointly developing Ocean Lake with EverWind. According to the company, Membertou holds a 51 percent ownership interest in the wind projects supporting the first phase of hydrogen production. A similar ownership framework is expected for future developments, although the structure for the second phase has not yet been finalized.
