摘要

An assessment of the wave energy potential in the exclusive economic zone (EEZ) of India using high-resolution daily climatology data (1993–2022) generated by the WAVEWATCH III model is presented in this article. This analysis is confined to the regions ranging from 0 to 150 m water depth, encompassing onshore (0–25 m), nearshore (25–75 m), and offshore (75–150 m) zones, where the wave energy converters (WECs) with the present technology can be deployed and operated. The identification of hotspots along coastal states, which have a year-round temporally consistent energy inflow within the feasible operational range of WECs, is achieved using a combination of a novel metric, consistency percentage and the cumulative annual available wave power density. The cumulative annual extractable wave energy from these hotspots is evaluated through a case study using two different WEC technologies. High wave energy potential hotspots have been identified, particularly along the coastal areas of the southern tip of the Indian mainland, the peninsular coast of Gujarat in the west, and the coastal region of West Bengal in the east. Onshore sites are recommended, as they are characterized by a nearly unidirectional wave energy inflow and experience only a minimal loss of approximately 15% when compared to offshore sites.
