The UN-backed International Seabed Authority (ISA) has issued 31 deep-sea exploration licenses, including two for India in the Indian Ocean, but is yet to allow mining because the 36-member body is still working on regulations.
The 36-member ISA council is meeting in Jamaica this month to negotiate the latest draft of a mining code.
M. Ravichandran, the top scientist at India's Ministry of Earth Sciences, said his ministry will work closely with India's mining industry as it readies to apply next year for exploration of seabed minerals in the Pacific.
India's critical minerals plans in the Pacific have not been previously reported.
China, Russia, and some Pacific Island nations have already secured exploration licenses for the Pacific Ocean.
India plans to focus on the Clarion-Clipperton Zone, a vast plain between Hawaii and Mexico known to hold large volumes of polymetallic nodules containing minerals used in electric vehicles and solar panels including manganese, nickel, copper, and cobalt.
First discovered by British sailors in 1873, the potato-shaped nodules take millions of years to form.
Unlike China, India lacks seabed mining expertise and will take at least three to four years before it is ready to extract minerals from the ocean's depths, experts said.
"We have done a lot of work on the deep sea mining technology but not perfected (it). In that aspect, we are not yet ready," said M. Rajeevan, former chief of India's Ministry of Earth Sciences.
Opponents of deep-sea mining say that not enough is known about its impact on marine ecosystems.
"I am not confident that current technologies and methods can overcome the environmental concerns," said Pradeep Singh, an ocean governance specialist at the Research Institute for Sustainability in Potsdam, Germany.
Some 27 countries have called for a moratorium or suspension of all ocean mining-related activities, but some Pacific nations including Nauru and Cook Islands favour deep-sea mining. Nauru is expected to submit a mining license application to the ISA on behalf of Canada's The Metals Company later this year.
India also expects to receive two more exploration permits from the ISA this year for the Indian Ocean, focused on the Carlsberg Ridge and Afanasy-Nikitin Seamount regions, known for polymetallic sulphide deposits and ferromanganese crusts, Ravichandran said.
The permits last for 15 years, according to the ISA website.
Polymetallic sulphide deposits contain metals such as copper, gold, silver and zinc. Ferromanganese crusts are known for cobalt, nickel, manganese, platinum and rare earth elements among other resources.
India, which relies on imports of raw materials such as copper and lithium, has listed 24 minerals as "critical" for energy transition. It is also scouting for overseas mineral assets to meet its rising green energy requirements.
"This is like racing," Ravichandran said of the urgency to seek seabed minerals.
