Special Issue Information

Dear Colleagues,

Substantial technological advancement is imperative for the scaled development of cost-effective ocean-based renewable energy technologies to facilitate the global transition to sustainable energy systems. Ocean renewable energy sources possess the potential to significantly contribute to this transition, with offshore wind farms and tidal current arrays offering substantial and predictable energy generation capacity. Significant research and development opportunities exist to advance ocean and tidal energy technologies toward commercial-scale deployment. Further research is necessary to achieve cost parity with established energy sources, as both offshore wind turbines and tidal hydrokinetic turbines exhibit considerable potential for cost reduction through technological innovation and economies of scale.

This Special Issue addresses critical aspects of offshore wind and tidal turbine technologies, presenting cutting-edge research findings that encompass the following:

  • Ocean Wind and Tidal Resource Assessment: Characterization and high-fidelity modeling of ocean wind and tidal current resources, including spatial and temporal variability analysis.
  • Offshore Wind and Tidal Energy Converter Development and Testing: Investigation of nearshore and offshore wind turbine technologies (fixed-bottom and floating) and tidal energy conversion devices. This includes novel design concepts validated through laboratory-scale experiments, field deployments, and advanced computational fluid dynamics simulations.
  • Structural Integrity and Fatigue Analysis: Analysis of component stress and fatigue under complex loading conditions, incorporating fluid–structure interaction analysis, experimental validation via laboratory and field measurements, and investigations of material fatigue behavior under cyclic loading and environmental stressors.
  • Wind Farm and Tidal Array Optimization: Optimization of wind turbine farm and tidal turbine array layouts, considering inter-turbine/device wake effects, power output maximization, and grid integration considerations.
  • Environmental Impact Assessment: Evaluation of the environmental impacts of ocean energy devices on marine ecosystems, including effects on marine mammals, avifauna, and fish populations, as well as analyses of sediment transport and benthic habitat disruption.
  • Field Deployment and Performance Evaluation: Reporting of field deployment results, including performance data, operational experience, and lessons learned from real-world deployments of ocean energy technologies.
  • Microgrid Integration and Energy Storage: Design and analysis of microgrid configurations incorporating ocean renewable energy sources to supply power to coastal communities, including the integration of energy storage systems to enhance grid stability and reliability.

In recent years, a growing global effort has been underway to reduce the Earth’s carbon footprint. One of the main strategies to achieve this goal is the utilization of available renewable energy resources. Among the largest and most inexhaustible is hydro-power. This paper presents an experimental study of three hydrokinetic turbines tested under real river conditions, aiming to evaluate their effectiveness in harnessing the kinetic energy of flowing water. The experiment is described in detail, including velocity field measurements conducted within the river section used for testing. Based on the experimental data, the main performance characteristics of the three turbines are presented, specifically their power output and efficiency. The importance of selecting an optimal riverbed site and customizing turbine runners to local flow conditions is highlighted, as even slight velocity fluctuations can significantly impact performance. Among the tested designs, the K1–6 turbine runner showed the highest power and efficiency, while the K2–4 runner provided superior rotational stability, making it promising for consistent energy output in variable flow environments Full article
