The Azura wave device designed to capture wave energy to generate electricity off Hawaii.

A New Plymouth company that built equipment to generate electricity from wave energy for offshore customers now plans to trial sites in New Zealand, including off the Taranaki coastline.

EHL Group (Energy Hydraulics Limited) successfully developed wave energy technology to compete internationally.

The company’s Azura wave energy device was chosen by the US Department of Energy for ocean trials in Hawaii, which led to the device supplying electricity to the island’s grid in 2015.

The device converted wave movement into hydraulic pressure to generate electricity using the kinetic wave energy.

EHL chief executive Peter Jannings​ said the company now planned a three stage development including a 250kW wave energy device, and four 500kW devices for New Zealand waters, including Taranaki’s Cape Egmont.
