“…In addition to that, it enhances the thermal conductivity, corrosion resistance, and abrasion resistance of heat exchangers [31]. Keshri et al had studied CNT-reinforced aluminium oxide coatings for marine and high temperature turbine coating applications and observed a 30 % reduced wear loss due to the reinforcement of 8 wt% of CNT's [32].…”

This chapter aims at providing an understanding about the potential applications of various types of coatings in energy sector. As the energy demands are growing day by day, there is need of enhancing the efficiency of energy systems, which can be enhanced using the advanced coatings. This chapter summarizes about the application of thin films and thick coatings of conventional/nanomaterials in both renewable and non-renewable energy sectors. A comparison between the efficiencies of systems with and without coatings has also been addressed. The importance and challenges associated with adding nanomaterials like carbon nanotubes (CNT), graphene, and various nanostructures with conventional coating material have also been discussed. This chapter can lead to better fundamental understanding about the coatings, which ensures new designs, high efficiency, and large application of coatings in energy sector. IntroductionEnergy has been the part of our life, especially electricity plays a vital role in our modern society. With an ever-increasing population, energy demand also growing faster for the past few decades. To meet the increased demand, every country has started to explore different energy systems to produce and store electricity in an efficient and most importantly in the eco-friendly way [1]. Hence, by increasing energy production, emission of greenhouse gases like carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) also rises to its peak. In order to decrease the emission of greenhouse gases, a worldwide initiation has also been in progress. Energy conservation steps have been introduced, either by reducing CO 2 emission from non-renewable sources like coal, natural gas, petroleum, and nuclear sources; or by avoiding such emissions using renewable energy sources as wind, water, sunlight, or biomass.

Geothermal energy is likely to be a significant contributor in achieving sustainable energy goals and net-zero emissions targets. Within geothermal power plants, heat exchangers play a critical role in harnessing this renewable energy source. However, these heat exchangers encounter significant challenges when exposed to geothermal fluids, including erosion, corrosion, and scaling, which adversely affects their performance and longevity. The current review focuses on surface engineering techniques, particularly coatings, as a highly effective and economically viable solution to address these challenges in geothermal heat exchangers. The review begins by providing an overview of geothermal energy, its significance in the context of sustainability and the important role played by heat exchangers in geothermal power generation, followed by the challenges and their impact on heat exchangers. The subsequent section focuses on surface engineering by coatings and its types employed to enhance the performance of heat exchangers. In the final part, the reader is presented with an overview of the challenges associated with the application of coatings in geothermal heat exchangers and potential future directions in this field. This review offers a detailed understanding of the critical role coatings play in improving the efficiency and service life of heat exchangers in geothermal power plants.
