Abstract: This paper introduces a novel tidal energy conversion concept specifically designed for low-range tidal environments (~1 m), where conventional tidal technologies are ineffective. The system employs a buoyancy–countermass coupled hydraulic design, capturing energy during both tidal uplift and gravitational descent. This bidirectional approach enables full utilization of tidal displacement, in contrast to turbine-based systems that harness only part of the flow. Key performance results indicate an overall efficiency of approximately 77%, straightforward modular scalability through caisson dimensioning and replication, and technical feasibility using existing offshore engineering practices. Together, these outcomes show that the system can be practically realized and adapted to different site conditions. By demonstrating that both feasibility and scalability are achievable, the study positions the proposed design as a practical foundation for new tidal energy solutions in underserved coastal regions. The concept represents a significant contribution to ocean energy research by showing that useful power can be generated even under minimal tidal ranges.
