N'GENIUS for Renewable Energy

Renewable Energy set to surge.

As a clean, sustainable alternative to traditional fossil fuels, renewable energy is regarded as a key enabler for the energy transition. The ability to generate electricity via ocean-based resources such as wind, wave, tidal and thermal energy will play a vital role in addressing climate change and reducing greenhouse gas emissions in the future.

High-performance advanced materials are fundamental to the infrastructure required for upscaling these renewable energy resources and overcoming the challenges involved in doing so. As a result, the demand for advanced materials is anticipated to grow continuously over the coming decades and beyond.

At present, stainless steels are utilised across offshore renewable energy facilities as dictated by the marine environment. Turbines in offshore wind farms, point absorber wave energy converters and tidal stream generators are just some of the many structures that require stainless steel components.

Corrosion is a serious problem for offshore renewable energy projects due to long term exposure to seawater, humidity, wave action and microbiological activity. Material selection therefore becomes an important process in preventing these issues along with reducing maintenance time and cost, whilst extending the service life of facilities.

How does the N'GENIUS Series™ help?

How does the N'GENIUS Series™ help?

Alloys from the N'GENIUS Series™ provide the best defence against challenging corrosive conditions and, with their improved mechanical strength properties, allow certain products to be manufactured with a reduced wall thickness, providing significant weight savings for offshore projects.

As such, it is possible for engineers to choose from a wide selection of advanced N'GENIUS™ materials which have a unique combination of mechanical and corrosion resistance properties and provide significant advantages for all major projects.

Performance benefits of the N'GENIUS ICONIC Series™ and the N'GENIUS INFINITY Series™ alloys for renewable energy projects include:

  • Unique combination of mechanical and corrosion resistance properties
  • Higher mechanical strength properties compared to conventional austenitic stainless steels for high pressure service and improved safety
  • Higher allowable design stresses
  • Reduced wall thicknesses can lead to weight savings, reduced transport costs and reduced fabrication time which results in less CO2 emissions and an overall reduction in construction and project costs
  • Excellent ductility due to a more stable single-phase austenitic microstructure
  • Excellent toughness at sub-zero and cryogenic temperatures
  • Superior resistance to Localised Corrosion (Pitting, Crevice and Intergranular Corrosion) in a wide range of service conditions and process environments
  • Superior resistance to General Corrosion even in low pH acid environments
  • Superior resistance to Hydrogen Embrittlement due to a more stable single phase austenitic microstructure
  • Superior resistance to Stress Corrosion Cracking (SSCC and Chloride SCC) in a wide range of service conditions and process environments
  • Increased safety can be built into system design.
  • Extended Service Life in view of their significantly improved corrosion performance
  • Improved through-life cycle costs and sustainability.
