What’s the Latest in Ocean Wave Energy Conversion Technologies for the UK?
From the soothing ebb and flow of the tides to the majestic roaring of the waves during a storm, the ocean is a perpetual motion machine. Harnessing this power for renewable energy is no longer a distant dream, but a tangible reality, especially in a maritime nation like the UK. As wave and tidal power technologies steadily evolve, they provide an increasingly significant contribution to the country’s energy mix. This piece will unravel the latest advancements that are revolutionising ocean wave energy conversion technologies in the UK. We will delve into the power of the waves, the potential of water as a renewable energy source, and the devices employed to tap into this power.
Harnessing the Power of Waves: An Overview
The ocean, with its endless cycle of waves, constitutes an incredible renewable energy source. Wave energy conversion (WEC) systems are designed to absorb this energy, usually in the form of oscillating or undulating motion, and convert it into usable electricity.

Several factors give wave power an edge over other renewable energy sources. Unlike wind and solar power, wave energy is more reliable and predictable, allowing for better planning and integration into the power grid. Furthermore, the energy density of water is significantly higher than that of wind, implying that a smaller device can harvest more energy from waves than wind turbines can from wind.

Ocean Energy Devices: From Point Absorbers to Oscillating Water Columns
The technology to harness wave power is diverse, encompassing point absorber systems, oscillating water columns, and overtopping devices, among others. Each of these devices utilises a different mechanism to capture the energy from waves, and each has its pros and cons.
Point absorber systems, the most common type of wave energy converters, consist of a floating structure that absorbs energy from all directions through its vertical movement. These devices are usually deployed offshore, where wave activity is high. Recent innovations have improved the efficiency and durability of point absorbers, making them a more viable choice for large-scale energy production.
On the other hand, oscillating water columns utilise a partially submerged, hollow structure. As waves pass by, they cause the water inside the column to rise and fall, forcing the trapped air above to flow through a turbine, thereby generating electricity. Although these systems are less efficient than point absorbers, they offer the advantage of being easily integrated into existing coastal structures like breakwaters.
The Potential of Marine Turbines
Marine turbines, akin to their wind counterparts, are another promising technology for harnessing ocean energy. These devices work on the same principle as wind turbines but are designed to operate underwater, where the higher density of water allows for greater power generation.
The UK, with its extensive coastline and strong tidal currents, is particularly well-suited for the deployment of marine turbines. In fact, the country is home to the world’s first commercial-scale tidal stream project, the MeyGen project in Scotland, which has been operational since 2016.
The latest generation of marine turbines is more efficient, robust, and environmentally friendly than their predecessors. They have improved rotor designs for better performance and are built with eco-friendly materials to minimise their impact on marine life.
The Future of Wave Energy Conversion: Ongoing Research and Innovation
Research and innovation continue to drive the wave power industry forward. Emerging technologies, such as artificial intelligence and big data, are being applied to optimise the performance of wave energy systems and to predict wave patterns more accurately.
One of the most promising areas of research is the development of hybrid systems that combine different types of ocean energy converters. For instance, devices that integrate wave and tidal power offer the potential to harness more energy and to provide a more stable power output.
Undoubtedly, the journey to make wave energy a mainstream renewable source has its challenges. These range from high upfront costs and technical difficulties to environmental and regulatory issues. Despite the hurdles, the potential of wave power is too large to be ignored, and the UK is at the forefront of turning this potential into reality.
In conclusion, ocean wave energy conversion technologies are evolving rapidly, driven by continuous research and innovation. As these technologies mature, they will play a crucial role in the world’s transition to a sustainable and carbon-free energy future.
CorPower Ocean’s Innovative Contribution
A significant name in wave energy conversion technology in the UK is CorPower Ocean. This Sweden-based company is renowned for its development of the hi-wave energy converter. The hi-wave energy converter is a point absorber type wave energy device that has shown exceptional promise due to its high efficiency and cost-effectiveness.
CorPower Ocean’s energy converter follows a principle known as resonance. It is designed to oscillate in harmony with the incoming waves, which significantly enhances the energy absorption rate. The hi-wave converter is also equipped with a pneumatic pre-tension system which adds stored energy to the system during periods of calm, making this converter more effective in different ocean conditions.
Notably, the hi-wave energy converter has been tested at the European Marine Energy Centre (EMEC) in the UK, one of the leading offshore renewable energy test facilities globally. It has shown impressive performance and resilience even in severe storm conditions, demonstrating the potential to be a reliable source of electricity.
Furthermore, the hi-wave converter’s compact and robust design minimises the impact on the marine environment. Its buoy-shaped structure reduces the visual impact, and its mooring system minimises the seabed footprint, reducing the potential for harmful interactions with marine life.
Overall, CorPower Ocean is drastically changing the wave energy landscape with its innovative approach to harnessing ocean power. The hi-wave energy converter is a testament to how cutting-edge technology can transform renewable energy resources into a viable and competitive energy source.
Optimising Wave Energy Conversion: The Role of Smart Technologies
In the quest to optimise wave energy conversion, smart technologies such as artificial intelligence (AI) and big data are proving to be invaluable. These technologies are being utilised to enhance the performance and efficiency of wave energy converters, ensuring a more reliable and predictable energy output.
AI can be used to create sophisticated control algorithms that allow wave energy converters to respond optimally to the ever-changing wave conditions. This means the converters can adjust their operations according to wave height, frequency, and direction, enhancing energy capture and reducing the risk of damage during storms.
Big data, on the other hand, can be used to predict wave patterns more accurately. By analysing data from a wide array of sources, including buoys, satellites, and oceanographic databases, predictive models can be built that forecast wave conditions days, weeks, or even months in advance. This allows for better planning and integration of wave energy into the power grid.
Moreover, smart technologies can also facilitate real-time monitoring of wave energy devices. This can help identify any potential issues early on, reducing downtime and maintenance costs.
In conclusion, wave energy holds immense potential as a renewable energy source. Although challenges remain, ongoing research and technological advancements are steadily overcoming these hurdles. Companies like CorPower Ocean are revolutionising the wave energy industry with innovative devices like the hi-wave energy converter. Furthermore, the integration of smart technologies is optimising the performance and reliability of these devices. As the UK continues to be a leader in harnessing ocean power, the future of renewable energy looks promising. Indeed, the power of the ocean waves may soon be a significant contributor to a sustainable, carbon-free energy future.
