What to look for?

Living in the Danish, Swedish and Norwegian part of the

North Sea, Skagerrak and Kattegat when looking at

utilising the sea for energy purposes

• The enormous potential for power general - maybe not so much in

the first years directly as energy supply

but

• The impact in the region in form of infrastructure and supply base

Grid Connections

The scenarios fall into two broad categories in regards to the connection philosophy

assumed for future OWE. The first is for radial connections only, whereby countries

continue to connect individual parks back to shore with HVAC or HVDC technology as

seen today. The second is a mix of radial connections (for near shore resource), along

with an offshore meshed grid where further from shore OWE clusters are directly

interconnected using HVDC technology (see below).

Wave Dragon principle

Turbine outlet

Reservoir

Waves overtopping the

doubly curved ramp

The Wave Dragon is a slack-moored wave energy converter that can be

deployed alone or in parks wherever a sufficient wave climate and a water

depth of more than 25 m is found.

The Tideng rotor

The rotor has 6 wings of which

3 are always extended

It may run in both directions

without loss of energy

There is no loss of efficiency

when angling the power plant

in relation to the current

HPS ApS has patent no. 1478847

The patent was approved 18.06.2008 and covers Belgium, Bulgaria,

England, France, Holland, Ireland, Italy, Luxembourg, Monaco, Portugal,

Slovakia, Spain, Sweden, the Czech Republic, Germany, and Austria.
