Helsingør-based Wavepiston, a Danish company providing wave energy solutions for power production and desalination, has secured €900K in funding from two professional investors through the Dutch joint venture company, The Blue Line BV.
The Blue Line is backed by Connect the Drops, a Dutch investment fund focused on the water sector, and Unknown Group, a Dutch VC fund that invests in the energy transition.
The investment was supported by Ronald Beuk and Generous Minds. “Wavepiston is a unique game-changer bringing wave energy to the world. We are pleased to have onboarded The Blue Line as an impact focused strategic investor.”
Capital utilisation
Wavepiston will use the funds for technological development, system validation in real-world environments, and forming strategic partnerships for market entry. The company aims to expand the renewable energy mix by advancing wave energy solutions.
Jan Otto Ooms, founder of Connect the Drops, says, “Innovation and sustainability go hand in hand. By harnessing wave energy to produce clean drinking water, we take a significant step toward a future where renewable energy and water security come together.”
Brief about Wavepiston
Wavepiston aims to integrate wave energy into the renewable energy sector by advancing solutions for power generation and desalination. The company seeks to expand the use of wave energy as a reliable source alongside other renewable options.
By developing and deploying its technology, Wavepiston works toward increasing energy access and water availability while reducing dependence on fossil fuels. The company’s efforts focus on establishing wave energy as a key contributor to global energy needs.
How does it work?
Wavepiston has developed a wave energy system that generates electricity and desalinated water. It operates using multiple energy collectors, each attached to a string.
The collectors have sails that move with the waves, powering hydraulic pumps. These pumps pressurize seawater, which is transported to a conversion station. There, the pressurized water drives a hydropower turbine to generate electricity or undergoes desalination through a reverse osmosis system.
Wavepiston’s energy farms consist of multiple strings, allowing for scalability based on location and energy needs. The system provides a renewable energy source, supports job creation, and contributes to local economies.
Research shows no harmful effects on marine life, and the equipment remains mostly submerged, reducing its visibility from the shore. The design minimises space requirements, making it adaptable for different environments.
In February 2025, Wavepiston completed the installation of the first of four upgraded energy collectors at PLOCAN in Gran Canaria. This was the initial deployment of the company’s third-generation energy collectors. The remaining units were planned for installation based on weather conditions and vessel availability.
