The ocean provides an abundant source of renewable energy, including wave energy. Established in Singapore Hann-Ocean Energy has been developing its proprietary wave energy conversion technology “Drakoo” (“Dragon King of Ocean” or “Coolest” in Chinese) since 2008. The Drakoo has been tested successfully in full-scale in the Singaporean sea, in the National Renewable Energy Centre (UK) and Hann-Ocean’s large-scale wave flumes. The device allows for cost-effective electricity generation from all scales of waves. Having had its first commercial pilot project (16kWp) for Sembcorp Marine in August 2013 and followed by four more years further data collection and product development, the latest 15kWp Drakoo WEC module has been developed and tested extensively to produce affordable and clean electricity from as low as 0.3m sea waves, with a peak efficiency of 46% from waves to electricity.
