Wave energy convertor devices capture the energy possessed by the waves (kinetic and potential) and transform it to electric power. Wave energy convertors are classified into different types of categories based on the deployed location. Onshore devices are of two types ‘Oscillating water column’ (trap air to run a turbine) and ‘Overtopping devices’ which uses height differences of waves to generate electricity. ‘Oscillating wave surge converters’, ‘Point Absorber’ and ‘Submerged Pressure Differential devices’ come under the near‐shore location category. Offshore devices are ‘Attenuator’, ‘Bulge wave devices’ and ‘Rotating mass converters’. Each of these devices has its own characteristics (Wilberforce et al. 2019). Worldwide many companies are involved in research and development (R&D) to exploit wave energy so that this technology can be commercialized (Lorente et al. 2011; www.aquaret.com). Some studies have revealed that theoretical global capacity of wave energy was 32 PWh (petawatt‐hour) per annum (Mørk et al. 2010; Lagoun et al. 2014) which was double of the global electricity provided in the year 2008 (Leonard and Michaelides 2018). These studies have suggested potential of this energy in future.
