Dexawave is the name of a danish company, which researches and developes a product that converts wave power into electrical energy. The produkt is a Wave Energy Converter called Dexawave. The idea is to create energy with the lowest possible environmental impact, and Dexawave is a simple and inexpensive way of harvesting energy from wavepower. The echonomic objectives are an initial capital cost per installed MW that can be compared to offshore wind turbines around 3.0 million Euros and a production cost pr KWh simmilar to the production cost for offshore wind turbines. Wave energy has an untapped energypotential up to three times the world energy consumption. Therefore it is crucial to develop and invent the right ways to harvest this potential. However it is very difficult to do and for the projects to succeed, its cost of energy must be competitive.

The challanges are that the sea is a very tough environment. The waves can be so tall that they destroy the wave power systems. Also wind power has the advantage that wind only blows one way at a time, but waves directions changes. And to bring the energy to shore is extremely expensive. The placement and design needs to take care of the challenges with both tides and currents.

Also there are strict environmental requirements that must be met in order to use the Wave Energy Converter, Dexawave. But in the future there might be three or four technologies emerging, and it is a way of making these different to fit the different climates.
