Production At ÉireComposites


ÉireComposites blades are made using the company’s patented MechTool®, a technology which has helped make valuable advances in the renewable energy sector.

  • 13m Blades – In 2013, ÉireComposites commenced manufacturing 13-metre blades for the Vestas V27 machine from glass fibre and epoxy resin.
  • 14m Blades – ÉireComposites, manufacture 14-metre wind-turbine blades for a derivative of the 225kW  Vestas V29 wind turbine.
  • Kingspan Blades – ÉireComposites produce glass-fibre reinforced polypropylene (Twintex) thermoplastic wind turbine blades for 6kW and 15kW Kingspan machines. GF/PP is an extremely tough, lightweight composite and provides for quiet and durable production of electricity from the wind. These blades can be recycled because thermoplastic materials are used.
  • OmniLink Blades – OmniLink Green Technology have developed and tested a diffuser-augmented-wind-turbine (DAWT) which uses a diffuser around the outside of the blades to accelerate the wind and hence increase the power captured.  The diffuser results in higher loads on the blades and can cause failures for low-quality blades. ÉireComposites has designed and manufactured high-strength, lightweight blades for the OmniLink turbine which can survive the high loads resulting from the diffuser.















PowderBlade is a €2.7m Horizon 2020 project to develop large wind blades (60m-100m). The project is based on a novel process for manufacturing blades from powder epoxy, developed by ÉireComposites.
The process eliminates the need to glue blade sub-elements together and hence reduces cost and weight. The PowderBlade project aims to modernise the production of large-scale wind turbine blades. By doubling the length of the blades, four times the energy can be captured. Longer blades can also achieve economies of scale for large offshore wind farms.

Objectives of PowderBlade:
• Design and manufacture a carbon fibre spar and glass fibre root for a full-scale hybrid blade.
• Design and test a torsion box for full-scale wind blade.
• Reduce cycle time for blade production.
• Commercialise the composite manufacturing technology for large wind blade application.
• Scale up manufacturing process so that hundreds of blades can be produced each year.

Partners include:




FloTEC is a €10m project that aims to reduce the cost of floating tidal energy through the delivery of a number of promising innovations on an enchained variant of Scotrenewables SR2000 floating tidal turbine. ÉireComposites’ scope is to develop higher performance tidal turbine blades at an affordable cost.

Targeted innovations for the project include:
• Improved energy capture through increased rotor swept area (9m blades).
• Advance lower cost manufacturing techniques in both turbine structure and blade.
•Centralised power conversion with integrated energy storage.
• Novel load dampers to reduce peak mooring loads.

ÉireComposites objectives:

• Determine an optimised composites structure and   manufacturing method for SR2000-2 blades.
• Design lighter more robust blades with higher fibre   volume fraction and straighter fibres.
• Reduce blade cost.
• Develop a technique for high volume and high-quality production.
• Perform extensive testing of materials and blade sub components to demonstrate the robustness of blades in ocean conditions.


Partners include:










MarinComp is a European Commission, Marie Curie 7th Framework Programme funded Project, under the Industry Academia Partnerships and Pathways. It aims to reduce the cost of offshore wind and tidal turbine blades and enable the drive toward lower cost per kilowatt renewable energy for both industries. Within MarinComp, ÉireComposites has performed extensive development of its powder epoxy technology and demonstrated that the technology has significant potential for applications in marine renewable energy.





MaREI – is a collaboration of universities. MaREI is the marine and renewable energy research, development and innovation Centre supported by Science Foundation Ireland. The MaREI Centre conducts fundamental scientific research relating to marine and renewable energy applications and enables the development and testing of technology through to the construction of demonstration systems. ÉireComposites is funding a blade testing project at NUIG’s large structures testing laboratory and is using these facilities to demonstrate the advantages of its blade manufacturing technology.
