Wave Energy Landscape in Europe: Riding the Green Wave Towards a Sustainable Future
Europe, with its extensive coastline and ambitious renewable energy targets, is at the forefront of wave energy development.
This clean, sustainable energy source has the potential to make a significant contribution to the continent's energy mix, helping to reduce carbon emissions and combat climate change.
Abundant Resource, Immense Potential
Wave energy is captured from the movement of ocean waves, using a variety of technologies such as buoys, overtopping devices, and oscillating water columns. The power generated depends on factors like wave height, speed, and frequency, as well as the efficiency of the conversion technology.
The potential of wave energy in Europe is vast. The Intergovernmental Panel on Climate Change (IPCC) estimates that the global resource could produce 29,500 TWh of electricity annually, almost ten times Europe's current consumption. This makes wave energy a highly attractive option for diversifying the energy mix and reducing dependence on fossil fuels.
Current Status and Challenges
While the potential is undeniable, the wave energy sector in Europe is still in its early stages of development. As of 2022, the total installed capacity is only around 12.7 MW, with most devices still in the testing and demonstration phase.
Several challenges hinder the wider adoption of wave energy. These include:
- Technology: Wave energy devices need to be robust and reliable to withstand the harsh ocean environment. Further advancements in technology are needed to improve efficiency and reduce costs.
- Grid integration: Integrating wave energy into the existing electricity grid poses challenges due to the intermittent nature of the resource.
- Financing: Investing in wave energy projects can be risky due to the uncertainties and immaturity of the technology. Financial incentives and support mechanisms are needed to attract investors.
Driving Innovation and Growth
Despite the challenges, there is a growing momentum behind wave energy in Europe. Several factors are driving innovation and growth in the sector:
- EU policy: The European Union has set ambitious targets for renewable energy, including a goal of 1 GW of installed wave and tidal energy capacity by 2050. This is supported by research funding and development programs.
- Collaborative initiatives: There are numerous collaborative efforts between European countries, research institutions, and industry players to advance wave energy technologies and share best practices.
- Technological advancements: Developers are continuously innovating and improving wave energy devices, making them more efficient, cost-effective, and reliable.

| Annual installations (2022) | N/A (lower than any year since 2010) | Ocean Energy Europe - Key trends and statistics 2022 |
| Annual installations (2021) | 681 kW | Ocean Energy Europe - Key trends and statistics 2021 |
| Cumulative installations since 2010 | 12.7 MW | Ocean Energy Europe - Key trends and statistics 2022 |
| EU target for 2050 | 1 GW | Ocean Energy Europe |
| Global resource potential | 29,500 TWh/year | Intergovernmental Panel on Climate Change (IPCC) |
Additional Notes:
- The table reflects data available as of 2023. More recent statistics may be available depending on the source.
- The "Currently operational capacity" figure is significantly lower than the "Total installed capacity" due to decommissioning of older devices and ongoing testing/demonstration phases for newer ones.
- The EU target of 1 GW by 2050 highlights the ambition for significant growth in the sector.
- The global resource potential figure showcases the immense potential of wave energy to contribute to the world's renewable energy needs.
Several pioneering wave energy projects are demonstrating the potential of this technology in Europe:
- Wave Dragon (Portugal): This project uses a floating overtopping device to capture wave energy and generate electricity. It has been operating successfully since 2008 and has generated over 20 GWh of clean energy.
- Oyster (Scotland): This point absorber device converts wave energy into electricity through a hydraulic system. It is currently undergoing testing and is expected to be deployed in an array in the near future.
- Seabased (Portugal): This project uses a bottom-mounted oscillating water column device to capture wave energy. It is currently in the pre-commercial phase and is expected to be deployed in 2024.
Key Takeaways:
- Wave energy is a clean, renewable energy source with vast potential in Europe.
- The sector is still in its early stages of development, but there is growing momentum and promising projects underway.
- Technological advancements, supportive policies, and collaborative efforts are key to unlocking the full potential of wave energy in Europe.
