Narec (National Renewable Energy Centre) is a UK centre for renewable energy and low carbon technologies. The centre develops prototypes, tests renewable devices to international standards, and is involved in installing low carbon technologies. It is very similar to other centres, such as NREL in the US[1] and National Centre for Renewable Energies (CENER) in Spain. Narec is based in Blyth, Northumberland.

History[edit]

Originally known as NaREC (New and Renewable Energy Centre), the centre was created in 2002 by One NorthEast, the North East regional development agency, as part of the Strategy for Success programme.[2] In 2010 the organisation changed its name to Narec (National Renewable Energy Centre).[3]

The organisation was originally involved in a wide range of technologies, including:

  • Wind (onshore and offshore)
  • Transmission and distribution
  • Photovoltaics
  • Oil and gas
  • Marine renewables
  • Fuel cells
  • Microrenewables
  • Biomass[4]

Since 2010 due to UK government cutbacks Narec has closed, sold off or separated different parts of the business. Now, Narec itself concentrates on testing blades and drive trains for marine renewables. The surviving other related parts of Narec are:

Narec Distributed Energy - An organisation which deals with microrenewables, energy efficiency, low carbon transport and city wide energy planning.[5] Narec Distributed Energy is 100% owned by Narec.

Narec Solar - 8% owned by Narec, and 92% owned by the Swedish firm Absolicon. This organisation is focused on silicon photovoltaic cells[6][7][8]

Narec Capital - A financial organisation run by Narec and Ashberg Limited.[9]

Narec Capital Risk Solutions - Beyond its existence, there is very little information on what this organisation does.[6]

Operations[edit]

Narec and its associated companies are involved in the following sectors:

Narec[edit]

Offshore Wind[edit]

Narec are involved in blade testing for wind turbines. The organisation is currently building new offshore wind testing facilities.[10][11][12][13]

Marine Renewables[edit]

Narec carry out small scale testing of marine renewable devices, such as the wave device Trident[14] and the tidal device Evopod.[15] New marine testing facilities are currently under construction.

Electrical Networks[edit]

In Narec's Clothier Laboratory the organisation was involved in high voltage testing. Work involved carrying out comprehensive testing and analysis services for transmission network operators, distribution network operators and manufacturers of electrical power equipment and accessories. Customers included National Grid plc.[16] Although Clothier is now closed some of these capabilities are now based in Blyth.[17]

Narec Distributed Energy[edit]

Energy Strategies[edit]

Narec Distributed Energy work with local authorities to design and carry out energy strategies. They have also released tools, such as the Microrenewables Toolkit, which can be downloaded from the company's website.[18]

Training[edit]

Narec Distributed Energy run accredited installer and designer courses for photovoltaics, solar thermal and air source heat pumps systems.[19] Narec is a cluster partner of the North East England hub for the National Skills Academy for Environmental Technologies.[20]

Also, Narec Distributed Energy have now started carrying out training for offshore wind technicians.[21]

Low Carbon Transport[edit]

Narec Distributed Energy have been involved in the North East Plugged in Places project, which has resulted in a large number of electric vehicle charging posts being installed in North East England.[22] Additionally, Narec Distributed Energy has been trialling the CUE-V electric car.[23]

Narec Distributed Energy are part of a project looking at low carbon solutions for cargo ships known as Inomanship.[24]

Small Scale Wind Testing[edit]

Narec Distributed Energy carry out testing of small wind turbines, in accordance with IEC 61400-25, and in 2010 accredited Evoco's 10 kW system.[25]

Heat Pumps[edit]

There is currently a research project with Northumbria University and Narec collaborating to design a new methodology to test heat pumps.[26]

Low Carbon Housing[edit]

Narec Distributed Energy helped design and worked on the energy strategy of the Reed Street Carbon Negative development of 21 dwellings in South Shields.[27]

Narec Solar[edit]

Photovoltaics[edit]

Narec Solar was the photovoltaic division of Narec, it was sold in April 2013 and continues to operate as the independent company Solar Capture Technologies.[28]

Narec Solar carried out a large amount of research using their Photovoltaic Technology Centre (PVTC). The majority of research was based around laser grooved silicon cells and concentrator photovoltaics, with additional work on coloured photovoltaic cells.[29] As well as being involved in public funded research and development Narec Solar manufactured silicon based concentrator cells, niche modules and also carried out private industrial research and development. One area of specilisation was in copper plating of silicon solar cells.

Published papers on photovoltaics include:

  • LGBC Silicon Solar Cell with modified bus bar suitable for high volume wire bonding[30]
  • Process and device modelling for enhancement of silicon solar cell efficiency.[31]
  • Study on laser parameters for silicon solar cells with LCP selective emitters.[32]
  • Combining Laser Chemical Processing and Aerosol Jet Printing: an industrially relevant high efficiency front side for silicon solar cells.[33]

Closed Facilities[edit]

Clothier High Voltage Laboratory[edit]

The Clothier Electrical Testing Laboratory was opened in 1970 by A. Reyrolle & Company. Narec took over the facility in 2004. The reason it was of interest to the renewable energy organisation was to use it to test the robustness of electrical infrastructure offshore locations to onshore sites, as well as to big load centres in the centre of the UK.[34]

Although one of the only high voltage testing facilities in the world, and completely unique in the UK, the facility was closed by Narec in 2011 due to a lack of government funding.[35]

Many parts of the lab were relocated to Narec's main campus in Blyth. The ruins of the original lab are now the property of Siemens.[36]

Current facilities[edit]

Photovoltaic Technology Centre[edit]

Narec's Photovoltaic Technology Centre (PVTC) was created when Narec took over BP Solar's staff and assets. It has now become Solar Capture Technologies Ltd., which is an independent company to Narec[37] PVTC has taken part in a number of large European Seventh Framework Programme projects.

These are: ASPIS - A project based on a novel Parallactic Tracking technology concept that supports flat, fixed solar panels with internal concentration and dynamic suntracking.[38] APOLLON - A project to develop High Concentration Point Focus and Dense Array Concentrator Photovoltaic (CPV) systems based on monolithic and discrete multijunction technology with a final target cost of 2 €/Wp.[39] 20plus - A project for the development of extra thin silicon solar cells.[40]

Charles Parsons Technology Centre[edit]

Built in 2004, this £5m facility contains a low voltage electrical laboratory for the testing of connecting renewable energy systems to the transmission and distribution grid.[41] Some of the equipment and staff from the closed Narec Clothier Electrical Testing Laboratory were moved to this facility[42]

Training Centre[edit]

The Training Centre is a retrofitted 19th Century terraced house. The technologies retroffitted on are; internal insulation cladding, photovoltaics, solar thermal panel, a heat pump and low energy LED lights. The centre is used to train installers for these technologies.[43]

Training Tower[edit]

This is a 27m high tower, for training of offshore wind technicians.[44]

Dry Docks[edit]

Narec tests marine devices with three modified dry docks.[45]

Tidal Testing Facility[edit]

The Tees Barrage Tidal Turbine Test Facility, Located in Stockton, was opened in 2007. Narec claimed to be the only independent large scale tidal testing facility for device prototypes in Europe.[46]

Wave Flume[edit]

A simulated wave environment for the testing of prototype wave energy generation devices.[47]

Blade Test I[edit]

The blade testing facilities at Narec are designed to test wind turbine blades up to 50m in length. Blades are tested using a Compact Resonant Mass (CRM) system. Narec is working on a technique of blade testing known as "Dual Axis".

European Funded Research[edit]

Narec is involved in a number of European Collaborative Seventh Framework Programme projects, the majority of which are photovoltaic technology based. These are either match funded or 75% funded, with the rest of Narec's finance coming from Narec itself. The projects are:
