What Exowave does
Exowave ApS is a Danish cleantech company founded in 2014 and headquartered in Esbjerg, Denmark, that develops and manufactures wave-energy technology for power generation and seawater desalination. The company's core technology is a submerged Wave Energy Converter (WEC) comprising a Wave Receiver, a Power Take-Off (PTO), and foundation components (monopile and transition piece) designed for water depths between 3m and 45m. The WEC captures hydrodynamic energy from oscillating waves and converts it into hydraulic energy, which can drive reverse osmosis for desalination via the ExoMare modular units (scaling from 4 m³/day to industrial capacity) or power conventional hydropower turbines for electricity generation in WEC clusters with a minimum 10 MW capacity. The architecture uses water as the energy carrier, reducing the complexity of marine electrical infrastructure.
The business model is direct enterprise hardware sales to a small set of large buyers: utility companies, offshore wind developers, island and remote-coastal governments, water-scarce communities, and offshore industries. The sales cycle involves technical feasibility studies and site-specific engineering assessments. Revenue streams include WEC hardware sales, ExoMare desalination systems, and hybrid wind-wave integration solutions that can boost offshore wind farm power output by up to 50%. Pricing is not publicly disclosed and is project-specific. The company maintains a multilingual digital presence (English, Italian, Spanish, French, Danish) and reports market activity in Denmark, Italy, Spain, Tanzania, and Cyprus.
Exowave is privately held under Danish law as an ApS, employs 1-10 people, and has secured approximately $3.5M across five funding rounds between 2020 and 2022, including a Danish Energy Agency grant. Strategic partnerships include JDC (September 2022), CA Gugler (April 2023), and an undisclosed joint venture announced in January 2025. The company is founder-led, with Gabriele Rampinelli serving as Managing Director and Martin Dahl as Chairman. No commercial revenue, institutional investors, or parent entity are disclosed; the company appears to be at a pre-commercial or early-pilot commercialization stage based on its customer profile of "feasibility site assessments."

Exowave product offering
Product offeringCore offering
Exowave manufactures and sells patented submerged Wave Energy Converter (WEC) systems and Power Take-Off (PTO) components that capture ocean wave hydrodynamic energy to generate clean electricity and drive wave-powered desalination (ExoMare) via reverse osmosis. Products are designed for water depths of 3-45m and are deployed as standalone installations for islands and remote regions, or integrated with offshore wind farms to boost combined power output.
Product overview
Exowave offers a portfolio of wave energy technology products for power generation and desalination. The core offerings include the ExoMare modular desalination system and large-scale Wave Energy Converters (WEC) for electricity production. WEC clusters supply pressurized seawater to conventional hydropower turbines for minimum 10 MW capacity. The products share a common technology foundation: converting ocean wave motion into pressurized water flow that drives either reverse osmosis for freshwater or hydraulic turbines for electricity. Hybrid Wind & Wave integration enables synergistic deployment with offshore wind farms.
