New Delhi: Scientists at the Indian Institute of Technology (IIT) Madras have created the "Ocean wave converter," which allows electricity to be produced from waves in the ocean. The trials were successfully finished during the second week of November 2022.
As per IIT Madras, the institute collaborated with Motilal Nehru National Institute of Technology (MNNIT) Allahabad and a start-up company called Virya Paramita Energy (VPE) for these experiments. During the experiment, the gadget was positioned at a depth of 20 m around 6 km off the coast of Tuticorin, Tamil Nadu.
In addition to this, the GKC Institute of Engineering and Technology and MCKV Institute of Engineering, West Bengal, devised the project's electrical storage system, and Waterfront Engineering and Infrastructure Private Limited assisted in placing it in the water.
In the next three years, this system hopes to generate one million watts (1 MW) of power utilising ocean waves. If the initiative is successful, it will achieve a number of goals, including those of the UN Ocean Decade and the Sustainable Development Goals (SDGs).
Additionally, it will also cover Deep ocean missions, clean energy, establishing a blue economy, and producing 500 gigawatts of power from renewable sources by 2023, which are just a few of India's environmental objectives.
The Ocean wave converter is intended for use in remote offshore locations that need dependable electricity and communication. It does this by providing electricity to payloads that are integrated into or on the device itself, as well as payloads that are situated nearby, such as on the seafloor and in the water column.
The oil and gas, defence and security establishments, and communication sectors are the main stakeholders for this gadget. Professor Abdus Samad of the ocean engineering department at IIT Madras has been working on this topic with a group of researchers.
A cutting-edge "wave energy and fluids engineering laboratory" (WEFEL) has also been built by Samad at IIT-M. Additionally, this lab is investigating alternative uses for this technology, such as providing power for smaller marine devices like data buoys and navigational buoys.
The Department of Science and Technology (DST), IIT Madras' "innovation research project," the Department of Foreign Affairs and Trade of Australia, and the Nidhi-Prayas and Australian Alumni Grant Scheme 2022 have all provided support for this study.
Samad highlighted the significance of this project by stating: “India has a 7,500 km long coastline capable of producing 54 GW of power, satisfying a substantial amount of the country’s energy requirement. Seawater stores tidal, wave and Ocean thermal energy. Among them, the harnessing of 40GW wave energy is possible in India".
“Even single devices in different locations along the Indian coastline can generate large quantities of clean power. We are also contemplating placing multiple devices in an array configuration for maximum wave power extraction from the location", he added.
In his statement, he further added that "Our vision is to make India sustainable by tapping the marine energy and net zero carbon emission to mitigate climate impact".
