Recent research published in the journal ‘Infrastructures’ sheds light on the promising potential of tidal energy in Buenaventura, Colombia, a coastal city that could soon harness this renewable resource. The study, led by Daniel Parrado from the Natural and Environmental Resources Engineering School at Universidad del Valle, utilized advanced 3D hydrodynamic and computational fluid dynamics (CFD) modeling to assess the feasibility of a tidal barrage power plant in Buenaventura Bay.
Tidal energy is generated through the movement of water caused by the gravitational pull of the moon and sun. This research focuses on tidal barrages, which are structures that use dams and gates to capture the energy from tidal movements. Unlike traditional sluicing methods, which can have negative environmental impacts, the proposed plant would operate without sluicing, minimizing potential ecological disruption.
The study revealed significant tidal current velocities in Buenaventura Bay, particularly during the Syzygy phase, where speeds reached between 9 and 11 meters per second. These high velocities indicate a substantial potential for electricity generation through tidal turbines. The findings suggest that even during less favorable conditions, like the Stoa phase, the plant could still produce electricity, with recorded flows exceeding 1 meter per second.
Parrado emphasized the significance of these results, stating, “For the first time, this research suggests that there exists a high possibility of implementing tidal barrage plants in Buenaventura City.” This could mark a pivotal moment for Colombia as it seeks to diversify its energy sources and transition towards more sustainable practices.
The implications of this research extend beyond energy production. The establishment of a tidal power plant could enhance local infrastructure, improve connectivity, and foster economic growth through job creation in construction and maintenance. Additionally, the project could attract investment in renewable energy technologies, positioning Colombia as a leader in marine energy in the region.
As the world increasingly turns to renewable energy to combat climate change, the findings from this study provide a roadmap for Colombia to harness its natural tidal resources effectively. Further research is recommended to explore water quality impacts and optimize turbine configurations, ensuring that the development of tidal energy aligns with environmental sustainability goals.
This pioneering work in tidal energy not only highlights the potential for electricity generation in Buenaventura Bay but also sets the stage for broader applications of marine energy technologies in Colombia and beyond.
