Microsoft Word Report 11 02 Wave Power final ex appendix doc

First commercial wave 
power leases granted 
A landmark was reached when in 
March 2010 the world’s first commer-
cial wave and tidal leases was granted 
in Scotland.
As new technologies there is an amount 
of uncertainness on behalf of authorities 
how to treat applications for marine 
energy. Thus only demonstration leases 
have been granted limited in time and 
size, for example a maximum of seven 
years and 10 MW in the UK. However 
the Pentland Firth and Orkney Waters 
Round 1 that was started in November 
2008 has now resulted in the first long 
term leases of seafloor for wave and 
tidal energy in the world. New rounds 
are expected to follow for other Scottish 
waters.
A total of 1200 MW leases were gran-
ted out of which 600 MW was for wave 
power. Wave power leases were granted 
to the utilities Southern & Scottish 
Electric (200 + 200 MW), E.On (50 + 
50 MW) and Scottish Power (50 MW) 
west of Orkney, see map. The wave 
power developer Pelamis got 50 MW 
site near the mainland. 
The precise details around the leases 
are not known, e.g. how long time the 
leases can be kept without development, 
but the companies will now be able do 
enter the statutory consenting process 
with guaranteed access to the seafloor. 
It will however take time to develop 
these sites, as there currently does not 
exist any transmission capacity between 
Orkney and the mainland.

Concepts
In the following a selection of concepts 
are presented. The thirteen Nordic 
concepts presented are the ones that to 
our knowledge are actively developed 
and in or near sea trials. A number of 
international concepts are also presen-
ted chosen by the criteria that they have 
full-scale (or near) grid connected sea 
trials on the way and in that respect can 
be seen as leading technologies.
There are also some well-known con-
cepts that for various reasons does not 
fulfil the criteria above but motivates a 
brief comment.
Archimedes Wave Swing
(AWS) is pro-
bably one of the most publicly known 
concepts due the demonstration of a 2 
MW grid connected unit in Portugal 
2004. AWS was originally developed in 
the Netherlands and it was the Dutch 
company that performed the Portugal 
demonstration. Immediately after the li-
mitedly successful demonstration the IP 
and name was sold to interested parties 
in Scotland and a new company AWS 
Ocean Energy was created. This com-
pany has attracted substantial private 
funding but has kept its development 
very secret. It is known that the current 
version AWSIII has moved far from the 
original concept but essentially nothing 
is publicly known about the actual 
design. AWS Ocean Energy first stated 
that they would have a demonstrator 
ready in 2008 but this has moved every 
year and the current target is 2011.
Orecon
had developed an offshore 
OWC design through tank and scale 
ocean tests phases and were on the stage 
to build a full-scale prototype. Howe-
ver, they failed to raise funds for this 
purpose and chose to close down the 
company in early 2010. It is not known 
what will happen with the IP.
Aquabouy
had it is background in the 
Swedish IPS-buoy and hose pump con-
cepts. After an U.S. sojourn it ended up 
in an Irish company, Finavera. Howe-
ver, in 2008 Finavera announced that 
they would not continue with the de-
velopment of Aquabuoy. The IPS-buoy
