Harnessing the Power of the Oceans: The Future of Tidal Wave Energy

What is Tidal Wave Energy?

Tidal wave energy, often referred to as tidal energy, is a form of hydropower that converts the energy obtained from tides into useful forms of power, primarily electricity. This energy harnesses the gravitational pull of the moon and the sun on the Earth’s oceans, which creates high and low tides. Tidal energy is considered highly predictable compared to other renewable energy sources, such as wind and solar power, making it a reliable source for generating electricity.

How Tidal Wave Energy Works

The primary methods for capturing tidal energy include tidal stream generators, tidal barrages, and dynamic tidal power systems.

  1. Tidal Stream Generators: These devices operate similarly to underwater wind turbines, where the kinetic energy from moving water currents turns the blades of a turbine to generate electricity.
  2. Tidal Barrages: These are large dam-like structures built across the entrance of a tidal basin. Water flows into the basin during high tide and is released through turbines during low tide, generating electricity from the flow of the water.
  3. Dynamic Tidal Power (DTP): This innovative method involves building long dams stretching out into the sea without enclosing any area. The movement of tides along the dam creates a head of water, which can be used to drive turbines and generate power.

Advancements in Tidal Wave Energy Technology

Recent advancements in technology have significantly improved the efficiency and viability of tidal wave energy. Here are some of the latest innovations:

  • Floating Tidal Stream Platforms: These platforms, such as those developed by Orbital Marine Power, float on the surface of the water with turbines submerged. This design allows for easier maintenance and better access to strong tidal currents.
  • Advanced Turbine Designs: Companies like SIMEC Atlantis Energy are developing turbines with enhanced blade designs and materials that can withstand harsh marine environments and operate more efficiently.
  • Modular and Scalable Systems: New designs are focusing on modularity, allowing tidal energy systems to be scaled up or down depending on the energy requirements and the local tidal conditions.
  • Smart Grid Integration: Integration of tidal energy systems with smart grid technologies ensures better management of energy production and distribution, maximizing the efficiency of tidal power plants.

Tidal Turbine Innovation: Profiling FastBlade, CoTide, and Weptos

Innovation in tidal turbine technology is crucial for the advancement and adoption of tidal wave energy. Three notable projects leading this innovation are FastBlade, CoTide, and Weptos.


FastBlade, a project by the University of Edinburgh, is pioneering a rapid testing facility for tidal turbine blades. This facility aims to significantly reduce the time required to test and validate new blade designs, ensuring faster deployment and commercialization of advanced tidal turbines. FastBlade uses hydraulic technology to simulate the stresses and strains experienced by tidal turbine blades in real ocean conditions. This innovative approach allows for more efficient and accurate testing, leading to the development of more durable and effective tidal turbines.


CoTide, another groundbreaking project, focuses on the co-design of tidal turbine blades to enhance performance and reduce costs. By integrating advanced materials and design techniques, CoTide aims to optimize the efficiency and lifespan of tidal turbines. The project involves collaboration between leading academic institutions and industry partners, leveraging cutting-edge research and practical expertise to push the boundaries of tidal turbine technology. CoTide’s holistic approach ensures that new tidal turbine designs are not only more efficient but also economically viable, promoting wider adoption of tidal wave energy.


Weptos, based in Denmark, is at the forefront of wave energy innovation. The Weptos wave energy converter is designed to efficiently harness the energy from ocean waves using a flexible structure that adapts to varying wave conditions. This technology allows for optimal energy capture and conversion, making it a versatile solution for different marine environments. The Weptos system has undergone rigorous testing and demonstrated high efficiency and durability, positioning it as a key player in the renewable energy sector.
