Havkraft AS
Havkraft AS is a Norwegian technology company specialized in wave energy conversion. The company finalized their prototype testing of the Havkraft Wave Energy Converter (H-WEC) in real sea environment at Stad in Sogn og Fjordane, Norway, in 2015 with ground breaking results. With over 4500 controlled running hours with power production, surviving direct exposed hurricanes and documenting a “cut-in speed” on the converters at 2 kW/m, the patented technology has proven its ability to produce energy in a very broad spectrum of frequencies. The current stage is to implement the wave energy converters into offshore aquaculture, offshore wind installations and other applications worldwide. The company is headed by inventor Geir Arne Solheim, in close team with Dr. Karl Christian Strømsem, Edgar Kvernevik, Agnar Lyng, Roger Flølo and a range of highly skilled partners, including Stadyard, Kvernevik Engineering, SmartMotor, Marintek Sintef, Christian Michelsen Research, Ulvesund Elektro and more.




Deep River 
Deep River has developed a mobile «plug and go» power plant which utilises the kinetic energy in rivers as well as tidal and ocean currents. A 250 kW pilot is under river and tidal testing during 2015 and 2016. The Deep River concept is turbine and generator on standard, container or pallet based solutions. Standardizing of dimensions eases both transport and installation. The power plants are fully scalable, both in number and size of turbines. The power plants may be built with a number of different anchoring solutions, and is deliverable with buoyancy tanks.

Deep River aims at an international market, seizing on the opportunity for local power production, off-grid solution, energy storage and easy grid connection. The technology has been developed in close collaboration with Norwegian and international universities, as well as with international suppliers and developers.


Tidal Sails
Tidal Sails AS, an independent, privately held closed corporation based in Haugesund, Norway, develops a ground breaking technology to extract kinetic energy from slow moving water by combining the ancient principles of ocean sailing with state of the art alpine ropeway technology. Linearly moving sails have great extraction efficiency, thus dramatically reducing the cost of the electricity generation. Tidal Sails technology can be adapted to most river, ocean and tidal current locations, and is protected by several patents worldwide. 

Tide Tec
TideTec is a Norwegian tidal company focused on developing the most efficient and flexible turbine technology for tidal barrage/lagoon and flood protection systems. TideTec holds several patents for state of the art tidal turbines and construction of tidal power plants. TideTec have patented a turnable turbine to be used in tidal-water power plants.

The turbine enables efficient two-way production (ebb- and flood production) in tidal power plants. In addition the TideTec turbines can be used for both forward and reverse pumping which increases the power production and the flexibility of production. The technology is intended to be integrated to existing or planned transport infrastructure, such as road bridges.

Ocean Energy
Ocean Energy AS has designed a worldwide 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 (www.ocean-energy.no). The project is supported by Innovation Norway and Ocean Energy plans to install a demonstration at Runde.

The company Flumill is planning to deploy its first commercial scale grid connected demonstration system at the marine test centre EMEC, in the UK. The system will be rated at 2 MW and produce up to 5 MW tidal energy at the EMEC location on Orkney Islands. The system will be deployed in 2017.
Langlee Wave Power The wave energy converter, named Langlee Robusto is a semi-submerged, floating steel structure anchored to the seabed with four chains. Wave energy is captured by large water wings that swing back and forth with the waves, converting the energy into electricity by generators with minimum loss. The electricity is connected to the onshore grid by a subsea cable.

Andritz Hydro Hammerfest
The company was founded in Norway in 1997 by the local utility company Hammerfest Energy and is currently owned by Andritz Hydro, Iberdrola and Hammerfest Energi. Andritz Hydro Hammerfest is among the leading tidal energy technology developers in the world and is now taking the step into commercial delivery. The Company has unrivalled commercial operation experience and has received Carbon Trust funding for the tidal turbine development. In December 2012 Andritz Hydro Hammerfest was awarded €20,7 million from NER300 for the proposed Sound of Islay project. Andritz Hydro is also part of the Meygen tidal energy project.
