Dutch wave energy converter for ‘very small sea states’ begins testing

April 23, 2026, by Nadja Skopljak

The Hague-based Wave Energy Collective (Weco) has teamed up with Rijkswaterstaat, part of the Dutch Ministry of Infrastructure and Water Management, to test its wave energy converter (WEC) capable of generating power even in very small sea states.

Weco reported today, April 23, that it had been developing the Denshi WEC over the past months and is collaborating with Rijkswaterstaat to test the device in a sheltered area at the Offshore Expertise Center (OEC) in the Netherlands.

Watch deployment

According to the Dutch firm, Denshi generates power even in very small sea states, effectively delivering baseload power from the ocean and is designed for rapid, low-cost deployment from small vessels, excluding the need for cranes, large vessels or complex infrastructure.

The testing is said to mark a major step toward real-world implementation.
