**Executive Summary**
Union Minister for Earth Sciences and Science & Technology Dr. Jitendra Singh reviewed the progress of the Ocean Thermal Energy Conversion (OTEC) project in Lakshadweep on March 06, 2026. This project aims to provide simultaneous sustainable water and energy supply by converting seawater into potable water and generating energy. The OTEC facility is intended to address long-standing freshwater challenges and reduce dependence on diesel-powered units.
**Key Points / Main Content**
* **Project Objective:** To convert seawater into potable water and generate energy using the temperature difference between warm surface water and cold deep-sea water.
* **Energy Application:** The energy produced will power desalination systems, ensuring a stable and sustainable supply of drinking water to Lakshadweep.
* **Addressing Water Scarcity:** The project aims to mitigate challenges related to limited groundwater, salinity intrusion, and dependence on seasonal rainfall in Lakshadweep.
* **Technological Advancement:** India is the first country globally to develop OTEC facilities, with this project being a pioneering effort.
* **Continuous Renewable Energy:** The OTEC system is designed as a continuous renewable energy source, unlike weather-dependent solar or wind power.
* **Environmental Benefits:** This technology can reduce reliance on diesel-powered units, thereby lowering fuel transportation costs and emissions.
* **Infrastructure Challenges:** Development in Lakshadweep faces logistical and engineering hurdles due to seabed conditions (coral formations, rocky strata, trenches) and limited operational windows during monsoons.
* **Broader Initiative:** The project is part of the government's Blue Economy framework to promote ocean-based technologies and enhance infrastructure, energy security, and climate resilience in island territories.
* **Future Exploration:** India aims to explore the technology's potential for other tropical island regions and coastal areas.
* **Demonstration Project:** Plans are underway for an offshore OTEC demonstration project under the Deep Ocean Mission.
**Impact Analysis**
**Island Communities in Lakshadweep**
* **Impact:** Improved freshwater availability and a stable, sustainable supply of drinking water. Reduced reliance on diesel-powered desalination units, leading to lower operational costs and reduced emissions. Enhanced energy security and climate resilience.
* **Action Required:** Benefit from the continuous supply of potable water and energy provided by the OTEC facility.
**Government of India (Ministry of Earth Sciences)**
* **Impact:** Successful implementation of a pioneering ocean-based technology, demonstrating India's leadership in renewable energy solutions for island territories. Progress towards achieving sustainable development goals and strengthening the Blue Economy framework.
* **Action Required:** Continue to monitor project progress, support infrastructure development, and explore wider applications of OTEC technology.
**Scientists, Engineers, and Project Personnel**
* **Impact:** Opportunity to work on a first-of-its-kind global project, facing and overcoming unique logistical and engineering challenges. Contribute to a critical national initiative for sustainable development.
* **Action Required:** Continue implementation, address technical challenges, ensure environmental safeguards, and work towards the commissioning timelines.
**Environmental Safeguards**
* **Impact:** The project requires careful consideration of environmental safeguards due to the delicate marine ecosystem of Lakshadweep, including coral formations.
* **Action Required:** Implement and monitor environmental safeguards throughout the project's lifecycle to minimize ecological impact.

Union Minister for Earth Sciences and Science & Technology Dr. Jitendra Singh on Friday reviewed the
progress of an Ocean Thermal Energy Conversion (OTEC) project during a visit to Kavaratti in
Lakshadweep, as the government moves to strengthen freshwater availability and renewable energy use in
island territories.
The Minister inspected the ongoing work at the OTEC-based desalination facility, a project designed to
convert seawater into potable water by using the temperature difference between warm surface water and
cold deep-sea water to generate energy. The energy produced is used to run desalination systems, aimed at
providing a stable and sustainable supply of drinking water to the island community.
Officials said the project seeks to address long-standing freshwater challenges in Lakshadweep, where
limited groundwater, salinity intrusion and dependence on seasonal rainfall have constrained reliable water
supply.
During the visit, Dr. Jitendra Singh reviewed the physical and technical progress of the plant and
examined key components such as the seawater intake system, the deep-sea cold-water pipeline, the
turbine-generator unit and the desalination modules. He also interacted with scientists, engineers and
project personnel involved in the implementation and reviewed timelines for commissioning along with
environmental safeguards. Officials also briefed him on plans for an offshore OTEC demonstration project
under the Deep Ocean Mission.
According to project officials, infrastructure development in Lakshadweep faces logistical and engineering
challenges due to the region’s seabed conditions, which include coral formations, rocky strata and
trenches. Work is also limited by narrow operational windows during monsoon months and rough sea
conditions, requiring specialised design and installation approaches.The OTEC-based system is designed to function as a continuous renewable energy source, unlike solar or
wind power which depend on weather conditions. Officials said this could eventually reduce the
dependence on diesel-powered desalination units, lowering fuel transportation costs and cutting emissions
while ensuring uninterrupted water supply for the islands.
Globally, India is the first in the world to develop OTEC facilities, including projects in Japan and the
United States. With the commissioning of the Kavaratti plant, India aims to join this group while
exploring the technology’s potential for other tropical island regions and coastal areas.
During the visit, Dr. Jitendra Singh said island regions face distinct challenges related to water availability
and energy security, and integrating ocean-based renewable energy with desalination could provide a long-
term solution for sustainable development in such locations.
Officials said the project is part of broader efforts to promote ocean-based technologies under the
government’s Blue Economy framework and to strengthen infrastructure, energy security and climate
resilience in island territories.******
