Waves4Power

Waves4Power is a Swedish-based developer of buoy-based Offshore Wave Energy Converter systems. Ongoing research and development is done in collaboration with Chalmers University of Technology. A partnership with Dutch engineering specialist BnD-Engineering in 2021 aimed to commercialize and deploy the system on a global scale.
The device is a floating buoy with a long vertical tube containing a "water piston"; this is out of phase with the passing waves, allowing power to be generated.
A demonstration plant was installed in February 2016 at the Runde Environmental Centre in Norway. This was connected via subsea cable to the shore-based power grid. It was the first grid-connected wave energy project in Norway, on 2 June 2017, and rated at 100 kW.
In November 2017, testing of the WaveEl 3.0 was halted a month early due to damage to the anchor. This device went through 12,000 hours of survivability demonstration, providing power into the Norwegian electricity grid for around 4,000 hours. The buoy was in diameter.
In 2018, ongoing long-term grid-connected testing of a 100 kW Wave-EL prototype at Runde was reported.
In 2020, the company received a grant from the EU-funded Interreg Ocean DEMO project, enabling it to access the grid-connected test berths at EMEC for three years. The plan was to have six WaveEL devices connected via a hub and have the device certified by a classification society. However, as of 2024, these tests have not happened.
In 2022, Waves4Power signed a memorandum of understanding with PLN Indonesia Power to develop wave energy parks.
