New Delhi: Union Minister Dr. Jitendra Singh reviewed progress of the OTEC project during a visit to Kavaratti in Lakshadweep as the government works to strengthen renewable energy and freshwater supply in island territories.
The project involves an Ocean Thermal Energy Conversion system linked to a desalination facility. It uses the temperature difference between warm surface seawater and cold deep-sea water to generate energy.
This energy powers desalination units that convert seawater into potable drinking water for island communities.
Officials said the initiative aims to address long-standing freshwater shortages in Lakshadweep. Limited groundwater resources, salinity intrusion and dependence on seasonal rainfall have affected reliable water supply in the islands.
During the visit, the minister inspected the technical and physical progress of the plant. He reviewed the seawater intake system, deep-sea cold-water pipeline, turbine generator unit and desalination modules.
OTEC project to support water and energy needs
Dr. Jitendra Singh also interacted with scientists, engineers and project personnel involved in the implementation of the facility.
Officials briefed him on project timelines and environmental safeguards. They also explained plans for an offshore demonstration project under the Deep Ocean Mission.
According to officials, infrastructure development in Lakshadweep presents logistical challenges. Coral formations, rocky seabed structures and trenches complicate engineering work in the region.
In addition, rough sea conditions and monsoon seasons restrict operational windows for installation activities.
The OTEC system can operate continuously as a renewable energy source. Unlike solar and wind power, it does not depend on weather conditions.
Officials said the project could reduce dependence on diesel-powered desalination units. This will lower fuel transport costs and reduce carbon emissions.
Globally, only a few countries have developed OTEC facilities, including Japan and the United States. With the commissioning of the Kavaratti plant, India aims to join this group.
The technology may also be used in other tropical island regions and coastal areas in the future.
The minister said island territories face unique challenges related to water availability and energy security.
He added that integrating ocean-based renewable energy with desalination can provide a long-term sustainable solution for such regions.
Officials said the initiative forms part of the government’s broader Blue Economy strategy to promote ocean-based technologies.
The programme also aims to strengthen climate resilience, infrastructure and energy security in island territories.
