What Wavepiston does
Wavepiston is a Danish wave energy company founded in 2014 and headquartered in Helsingør, Denmark, with additional operations in Spain and a team of approximately 20 employees. The company's core technology converts ocean wave motion into pressurized seawater, which is then used to drive conventional hydropower turbines and/or reverse osmosis desalination systems. The platform is differentiated by a patented force cancellation concept (granted 2009) that reduces mooring and structural loads to less than one-tenth of conventional wave energy converter designs, and a second patent on the power take-off system (granted 2018). The architecture is fully submerged and modular, with no active controls in water, which is intended to lower installation, maintenance, and balance-of-plant cost relative to surface-piercing point absorbers.
The company's product surface is the Wavepiston wave energy converter sold at farm scale, with a parallel managed-service offering for desalinated water production. Its go-to-market targets enterprise customers including governments, utilities, and offshore wind developers, and its first commercial revenue came from a technology assessment contract with Shell Marine Renewable Energy. Wavepiston supplements private capital with non-dilutive funding from EU programs, including a €4M Horizon Europe grant for the SHY flagship R&D project and a €3M grant for the COHSI-WEC project, and has run equity crowdfunding rounds on Seedrs. Total capital raised across all rounds is approximately €18-20M, of which roughly €6M+ is EU grant funding.
The company's near-term strategic posture centers on technology validation, partnership-led market entry, and geographic expansion into high-wave-energy and water-stressed markets. The 2024 full-scale demonstration at the PLOCAN test center and a partnership with Ørsted anchor the offshore-wind-adjacent value proposition, while 2026 MoUs with Haf-Afl (Iceland) and Export Barbados extend the addressable market into the North Atlantic and Caribbean, where island-grid and high-cost-desalination economics favor wave-driven energy and water systems.

Wavepiston product offering
Product offeringCore offering
Wavepiston designs, develops, and sells modular wave energy conversion systems that transform ocean wave motion into pressurized seawater via oscillating energy collectors coupled on strings. The pressurized seawater is piped to onshore or offshore conversion stations to drive standard hydropower turbines for electricity generation and/or reverse osmosis systems for desalination. The system is fully submerged with no active electronics in the water and uses a patented force cancellation architecture that reduces mooring loads to less than 1/10, enabling lightweight, cost-effective, and visually unobtrusive wave energy farms.
Product overview
Wavepiston offers a wave energy conversion system consisting of modular energy collectors coupled on strings that convert wave motion into pressurized seawater. The pressurized water drives hydropower turbines for electricity generation and/or reverse osmosis systems for desalination. The core system is complemented by multiple R&D projects including COHSI-WEC (next-generation energy collectors), SHY Project (seawater hydraulic PTO), and MORE (marine materials). Wavepiston operates demonstration projects at PLOCAN in Gran Canaria and develops commercial pilots in Martinique, Barbados, and Iceland, targeting utility-scale wave energy with a LCOE target of €39/MWh.
