In the oil and gas industry, thermally sprayed aluminum (TSA) coatings are commonly used, primarily, to reduce anode demand in cathodic protection systems and impart some degree of sacrificial protection in the topsides and splash zone areas. The use of TSA coatings has advantages in systems where long service life is required. TSA coatings are also used to reduce the formation of calcareous deposits, normally a combination of CaCO₃ and Mg(OH)₂, on heat exchanger piping.

Several components in geothermal power plants need to be protected from the environment due to the corrosive nature of geothermal fluids used to generate the energy. Depending on the fluid properties for any location, the type of protection varies. In geothermal power plants, wear, erosion, corrosion, and scaling are all known problems1. These issues can lead to a variety of outcomes, ranging from decreased plant efficiency to upstream component failure. Failure of a component is thus a significant challenge in the geothermal industry, where materials need to operate in high temperature and high pressure environments. A major cost factor is also linked to the drilling of geothermal wells, where cost rises due to increased depth/distance of drilling, increased trip times, higher high temperature and high-pressure conditions which can lead to increased wear and corrosion of the materials. To address the issue, coatings can be considered to be a potential solution to extend the service life of downhole equipment.

Offshore wind turbines are subjected to a harsh marine environment, which can cause detrimental problems to them due to corrosion, if not protected properly. Offshore wind energy is considered to play an important role in the net zero emissions by 2050, as set in Paris Agreement [1], contributing to environmental protection and sustainability. Thus, the long-term corrosion protection and life expansion of these offshore structures is of high importance. In this work, the formation of microcapsules, loaded with corrosion inhibitor liquid is presented. More specifically the microcapsules consist of polystyrene shell-an inert material- and 3-octanoylthio-1-propyltriethoxysilane core with a mean diameter of around 80µm. Silanes are used as corrosion inhibitors due to their chemistry, which offers protection to the underlying substrate [2, 3]. The incorporation of the microcapsules in a commercially available paint and their anticorrosion performance was tested in salt spray chamber and in real marine environment. Hence, this work highlights the performance of the microcapsules, which can offer corrosion solution to offshore wind turbines when used as part of a coating system. EDX analysis of the exposed samples lead to conclusions regarding these systems, contributing to the existing literature.
