Marine in Norway

Tidal energy

A 300 kW prototype tidal power plant was installed in September 2003 in the Kval Sound in the far north of Norway. The world’s first grid-connected offshore underwater turbine, located at Kvalsundet, close to Hammerfest, was successfully tested for a period of four years prior to being removed during 2008 for inspection. In order for further research to be conducted the turbine was reinstalled in situ during the summer of 2009.

During 2008 Hammerfest Strøm AS collaborated with ScottishPower to form Hammerfest Strøm UK. The 100% owned subsidiary was established with the intention of licensing and developing the Norwegian technology. In February 2010, the new company, based in Scotland, received a GBP 3.9 million grant from the Carbon Trust for the construction and testing of a 1 MW full-scale demonstration turbine (HS1000™) in Scottish waters at EMEC, prior to commercialised deployment.

A 1.5 MW floating tidal power plant – the MORILD demonstration project – is planned for deployment during 2010 in the Gimsøystraumen tidal current in the Lofoten Islands. It has been reported that connection to the grid is planned for end-2010.

Wave energy

Norway has an attractive wave energy resource and there are several national programmes and targets for renewable energy in Norway, but none are specific for ocean energy. Similarly, there are several government support mechanisms for technology development, prototype and full-scale test devices for renewable energy, but no specific support exists for ocean energy. Nevertheless, some companies have received significant funding, (e.g. Langlee Wave Power received a grant from the Research Council of Norway in 2009).

The Norwegian University of Science and Technology in Trondheim (NTNU) has long been involved in several research and development projects relating to wave, including the EUsponsored SEEWEC project. Statkraft, the stateowned utility, has allocated € 10 million over a period of four years for an ocean energy university programme for focusing on offshore wind, wave and tidal energy in three Nordic universities (NTNU, Norway; University of Uppsala, Sweden; and the Technical University of Denmark); the universities will have to match the projects financed by the programme.

There is some commercial activity in Norwegian wave energy:

Tussa Kraft and Vattenfall are testing 40 kW Seabased technology devices outside Runde on the west coast of Norway;

The Fred. Olsen company was actively involved for three years of testing (with the research rig ‘Buldra’) of ‘FO3’ multiple point absorbers on a single vessel. This was a part of SEEWEC, a consortium involving 11 partners from 5 EU-members (Belgium, The Netherlands, Portugal, Sweden and the UK) and 1 associated country (Norway). Its final report indicated that arrays of single point absorbers would be better;

WAVEenergy is presently working to build its own test 300 kW SSG unit at Svåheia on the coast near Egersund for 2011 and has recently started a feasibility study for Hanstholm Harbour for a 10 MW project in January 2010;

Langlee Wave Power has conducted R&D on a 1/20th scale model of its floating wave energy device and is currently looking to deploy a prototype device in 2010. It is reported to have an agreement with the Turkish renewable energy company Ünmaksan for a 24 MW commercial facility to be deployed in Turkish waters, presumably in the form of a combined wind-wave system.
