Langlee Wave Power 2012
The technology that Langlee offers is based on the valuable experience of offshore petroleum engineering
in Norway. As a result of marine renewable energy research since the inception of the company in 2006,
Langlee has developed a wave energy converter that will produce electricity at a lower cost with respect to
existing technologies, without compromising the quality, efficiency and with no visual impact.
Langlee Wave Power has decided to devote all its efforts in a unique area, and boost afterwards growth to
a global market. With this idea in mind, Langlee has established a Spanish subsidiary in Gran Canaria, in the
field of the ZEC (Canary Islands Special Zone), with the most attractive tax incentive and best wave power
conditions in Europe. The first prototype converter wave power rated at 100 kW could produce around 300
MWh of clean energy per year on the Canaries, corresponding to about 300 households.
Langlee Wave Power and Zamakona shipyards have recently signed an agreement for the local production
of the metal structure. Zamakona, which is one of the most important shipyards and repair groups in
Spain, along with Langlee Wave Power, will work together in a consortium to develop its activities in the
framework of the EEA Grants. Langlee is receiving subsidies funding from Innovation Norway.
Intentium
The Norwegian company Intentium AS has been developing an offshore floating wave energy converter
since 2007. With a wider stabilized float, energy from a larger width of the wave front is harvested. The
concept emphasizes robust solutions by using a PTO with hydro-power similarities, disconnected from
the moorings. In 2012, the concept has gone through extensive ocean basin testing at Aalborg University,
through the EU funded initiative MARINET. Results, backed up by previous numerical simulations conducted
by SINTEF MARINTEK, show a persistent efficiency through a diversity of wave conditions. Present status
indicates a first large-scale prototype in the order of 200kW.
Flumill
The company Flumill has obtained a licence from NVE for deploying up to 5 MW tidal energy production in
Rystraumen in Troms in the northern part of Norway. A grid connection arrangement has been entered into
with Troms Kraft.
Flumill is planning to build and install a full-scale grid connected demonstration system in Rystraumen in 2013.
Enova has granted support of NOK 57,3 million to the project. The demonstration system will have a rated
capacity of about 2 MW.
Deep River
Deep River has developed a tidal, current and river plant. The company plans to install a demonstration
system in a Norwegian tidal stream in 2013.
Tidal Sails
Tidal Sails is developing and constructing energy plants generating electricity from ocean currents and tidal
streams. Aluminum sail profiles attached to wires sail with the current at an angle, capturing energy and
converting it into clean electricity. Linearly moving sails have great extraction efficiency, thus dramatically
reducing the cost of the electricity generation. Tidal Sails technology may be used in different settings and
is protected by several patents worldwide.
Tidal Sails has a small scale demonstrator operating in a stream outside Haugesund, Norway. This has a
nominal capacity of 28 KW, and provides an excellent basis for scaling up systems to the range of several
MW. The hydrodynamic forces work exactly the same in any scale.
In 2012, the company has delivered an application for a demonstration project of 3MW at Kvalsundet near
Hammerfest, in Norway. Yearly production is estimated to be 8 GWh.
Ocean Energy
Ocean Energy AS has designed a wordwide patented wave energy plant. The technology is based on
the Swedish wave company Seabased AB, but Ocean Energy has developed and patented a “Storm
Buoy”. The Storm Buoy can be submerged and withstand extreme waves. The solution is developed in
cooperation with the leading environments at universities in Norway (NTNU) as well as the “Maritime
Cluster” at Ulsteinvik, Sunnmøre in western Norway.
The project is supported by Innovation Norway and Ocean Energy plans a demonstration at Runde in 2013.
