As the demand for clean energy surges across North America, the Great Lakes region is poised to become a focal point for innovative hydropower solutions. With escalating electricity costs affecting both residential and industrial consumers, companies like the Ocean Renewable Power Company (ORPC) are turning to submersible hydroelectric technology to harness the untapped potential of the region’s waterways. This development comes at a critical time as cities like Montreal, Toronto, and Chicago face increasing energy requirements.
Harnessing the Power of Waterways
The Great Lakes, despite their vast freshwater resources, lack substantial tidal or current flow to support traditional hydropower. However, the rivers connecting these lakes, particularly the St Lawrence and Niagara Rivers, provide a unique opportunity for energy generation. ORPC’s foray into urban hydropower in Montreal marks a significant step forward. CEO Stuart Davies noted, “The St Lawrence River is one of the best opportunities in North America for our technology because it has consistent, high-velocity water for hundreds of miles. In the Montreal area, there’s 60-90 megawatts of resource potential alone.”
ORPC’s devices, featuring carbon fibre turbines reminiscent of traditional lawnmower blades, are designed to produce electricity from the kinetic energy of flowing water. The company’s upcoming installations represent a shift towards sustainable energy generation in urban settings, aiming to provide a reliable power source amidst a backdrop of rising electricity prices.
A Growing Demand for Clean Energy
Electricity rates have skyrocketed in regions surrounding the Great Lakes, particularly in western New York, where residents have faced significant hikes in their bills. This trend is echoed in Michigan and Ohio, where energy demands are strained by the rise of data centres and industrial applications. While ORPC’s devices can only generate between half a megawatt and five megawatts, Davies argues that they can serve as a dependable energy resource for industrial customers, particularly those reliant on continuous power for operations such as artificial intelligence.
The current landscape of energy production is shifting, and the emergence of marine energy technologies is timely. ORPC is set to expand its operations with a second project along the Niagara River in Buffalo later this year, further establishing its footprint in the region.
Environmental Considerations and Challenges
Despite the promising advancements in hydropower, the deployment of turbines in ecologically sensitive areas raises environmental concerns. Environmental advocates, such as Anne KC McCooey from the Black Rock Riverside Alliance, emphasise the importance of responsible energy development. “You can’t put something up just for the sake of harnessing the energy, while at the same time doing harm to the environment and the human and non-human life that depend on that environment,” she stated.
ORPC has maintained a commitment to sustainability, citing successful operations in Alaska where their technology has not caused harm to local fish populations. The absence of saltwater in the Great Lakes region also presents an opportunity, as it mitigates corrosion issues commonly faced in ocean-based projects, thereby extending the longevity of hydropower devices.
Innovating for Future Generations
Innovative technologies are being explored to further optimise hydropower generation in slower-moving waters. At the University of Michigan, Professor Michael Bernitsas is developing a device called Vivace, which can harness energy from water moving at minimal speeds. This technology could be pivotal for regions with less forceful currents, allowing for broader implementation of hydropower solutions throughout the Great Lakes.
Davies shared the company’s ambitions to continue expanding, with plans for a project on the lower Mississippi River as soon as next year. “The biggest [challenge] is just the lack of awareness of our solution, but that’s really flipped in the last nine months,” he remarked. With federal support for renewable energy evolving, ORPC anticipates increased interest from international partners eager to explore sustainable solutions.
Why it Matters
The rise of hydropower technology in the Great Lakes represents more than just an energy solution; it is a critical response to the pressing challenges of climate change and energy sustainability. As cities grapple with rising electricity costs and increasing consumption, innovative hydropower projects could provide a reliable, eco-friendly alternative. The success of these initiatives not only holds promise for energy security but also underscores the importance of environmental stewardship in the pursuit of clean energy.
