Pelagic Power
The Pelagic power W2-Power concept 
is a hybrid wave and wind energy 
converter. 
The wave energy part of the machine 
is based on wave pumps that pump 
seawater to a water turbine.
The wave pump solution has been 
tested in 1:3 scale in real sea. 
The full concept, with platform and 
wind turbines has not been subjected to 
scale tests to date.

DEXA WAVE
The DEXA WEC is an attenuator device 
where different parts of the machine ex-
periences different phases of the waves. 
The relative motion between the two 
pontoons drives the hydraulic PTO.
A full-scale DEXA converter is envisa-
ged to have a rated capacity of 250 kW. 
The device has been subjected to sea 
trials in 1:10 scale in Limfjorden in 
northern Jutland.
The next step for DEXA is 
to test a 1:5 scale machine 
in real sea. This camping is 
planned for the fall of 2010.
Wave Dragon
The Danish Wave Dragon WEC is a 
large floating platform with two long 
arms in the front. 
Together, the two arms serve as a collec-
tor for the water reservoir onboard the 
platform. The platform is trimmed to 
the actual wave height by an air cushion 
to maximise wave capture.
Once water has been collected in the 
onboard basin it is let out to the ocean 
through low head Kaplan turbines. 
The Wave Dragon has been tested in 
1:4,5 scale at the Danish wave energy 
test site in the Nissum Bredning. A full 
scale Wave Dragon is envisaged to have 
a rated capacity of around 10 MW. 
In 2007 Wave Dragon had the permit as 
well as the funding (public and private) 
for a full-scale demonstrator in Wales. 
However, the unfortunate death of the 
owner of private partner company stop-
ped project and Wave Dragon has since 
been looking for funding for the project, 
as far as known yet without success.
