Demand for hydropower surges as Trump clamps down on clean energy
Home to one of the world’s largest deposits of freshwater, the Great Lakes region will soon host next-generation generators – just as prices are being hiked across the US
TL;DR
- Submersible hydroelectric technology is being deployed in the Great Lakes region to meet surging electricity demand and costs.
- The Ocean Renewable Power Company (ORPC) is launching projects on the St. Lawrence River in Montreal and the Niagara River in Buffalo.
- These devices use carbon fiber turbines powered by water flow, with successful deployments in Alaska and Maine.
- While North America catches up, projects in Scotland and Korea demonstrate the growing efficiency of current- and tidal-powered generators.
- Rising electricity prices across the Great Lakes are increasing interest in alternative energy sources.
- The technology can provide a 24/7 electricity resource, serving as baseload power and offering emergency power if the grid fails.
- Challenges include environmental concerns regarding wildlife and the lengthy licensing process in the US, which averages eight years.
- ORPC states its Alaska project has shown no record of fish injuries.
- Researchers are also developing technologies like Vivace to harness energy from slower-moving water, expanding potential locations.
- Operating in freshwater Great Lakes avoids corrosion issues common in ocean-based projects, reducing costs.
- Lack of awareness is a challenge, but a recent increase in interest is noted, partly due to the retention of marine energy tax credits.
- Entities from over 70 countries have inquired about the technology.
