As the world increasingly turns to renewable energy sources, tidal energy is gaining attention for its potential as a reliable and environmentally friendly option. Recent research conducted by Handoko Catur Rakhmad from the Department of Ocean Engineering at the Sepuluh Nopember Institute of Technology sheds light on the performance of hydrostatic transmission systems in tidal energy conversion. This study, published in “E3S Web of Conferences,” provides valuable insights into the efficiency and operational challenges of these systems.
The research focused on a prototype tidal stream power system that included a turbine simulator, hydraulic transmission, and a permanent magnet synchronous generator (PMSG). By testing the system under various torque settings, the team aimed to determine its ability to optimize performance by separating submerged components from those above sea level and enhancing rotational speed.
Despite delivering the desired speed gain, the hydrostatic transmission (HST) system exhibited relatively poor efficiency, averaging around 22%. Rakhmad noted that “efficiency loss results from elements including hydraulic fluid viscosity, internal wear, and shaft alignment.” These findings highlight significant areas for improvement, suggesting that further research is essential for enhancing the reliability and performance of HST systems in tidal energy applications.
The implications of this research are considerable for the energy sector. As companies and governments invest in renewable energy infrastructure, understanding the limitations and potential of tidal energy systems can guide future developments. Improved efficiency in HST systems could lead to more viable tidal energy projects, attracting investment and fostering innovation within the sector.
For those interested in the technical aspects of tidal energy and its commercial viability, Rakhmad’s work emphasizes the need for continued exploration and development. The findings not only contribute to academic discourse but also serve as a stepping stone toward more effective tidal energy solutions that could play a critical role in the global transition to sustainable energy sources.
