Nanospan launches graphene-enhanced corrosion inhibitor for offshore wind farms
Nanospan commercially launched GalvaShield-G, a graphene-enhanced corrosion inhibitor coating for offshore wind turbine towers and monopile foundations, priced at EUR 18 per litre and produced at its Hyderabad facility at 1,200 tonnes per annum capacity. The product demonstrates a commercial application of graphene in protective coatings for harsh marine environments, with third-party-validated maintenance interval extension from 5 to 12 years supporting the case for graphene's functional value in infrastructure composites.
Nanospan has introduced GalvaShield-G, a graphene-enhanced corrosion inhibitor coating designed for offshore wind turbine towers and monopile foundations. This product reportedly extends maintenance intervals from 5 to 12 years, as verified by third-party accelerated weathering trials conducted by TUV Nord. The pricing is set at EUR 18 per litre, with a minimum order quantity of 500 litres. Initial customers include two unnamed European wind operators managing over 800 turbines collectively.
According to Nanospan CEO Sarah Linfield, GalvaShield-G addresses significant operational costs associated with in-situ maintenance from service vessels in challenging sea conditions. The coating is compatible with standard spray equipment and cures in less than 4 hours at 15 degrees Celsius. The company's Hyderabad facility has a manufacturing capacity of 1,200 tonnes annually, with plans to expand to 3,000 tonnes by the third quarter of next year. This launch follows a three-year development collaboration with Larsen and Toubro's offshore engineering division.
