The story thus far: The Union Ministry of Mines introduced on Thursday, February 10, that lithium reserves had been present in Jammu and Kashmir, a primary within the nation. The Geological Survey of India established 5.9 million tonnes of inferred lithium sources within the Salal-Haimana space of Reasi District in Jammu and Kashmir.
Officials within the Union Territory stated the invention might enhance the manufacturing of rechargeable batteries for electrical automobiles, smartphones, and laptops and lower India’s dependence on lithium imports. Currently, India is totally import-dependent for minerals like lithium, nickel, and cobalt.
Why is lithium so necessary?
This gray, shiny, non-ferrous metallic is the lightest and the least dense of all metals. Being the third factor within the periodic desk after gases hydrogen and helium, the alkali metallic lithium is extremely reactive. Multiple nations have ramped up efforts to search out reserves of lithium, generally dubbed ‘white gold’, in what has been known as the “new era gold rush”. From about 500,000 metric tonnes (MT) of lithium carbonate equal (LCE) in 2021, the demand for lithium is anticipated to achieve three million to 4 million MT in 2030.
In January this yr, the usgovernment introduced loans price $700 million to a metallic producer to construct a lithium mining challenge within the State of Nevada. As the European Union makes an attempt to bolster its personal provide of lithium, European Commission President Ursula von der Leyen stated final yr that “lithium and rare earths (elements) will soon be more important than oil and gas.”
So, why is lithium in such demand? Besides being utilized in batteries to energy smartphones, laptops and different devices, lithium is a vital part within the rechargeable batteries that run electrical autos (EVs) and in storage batteries for vitality from renewable sources.
As nations transfer towards clear vitality applied sciences to fulfill their Paris Agreement local weather pledges, the transition to electrical autos is essential as vehicular air pollution accounts for a major proportion of carbon emissions. The U.S. plans to make 50% of its new car fleet electrical by 2030. The EU in October authorized a ban on the sale of recent petrol and diesel automobiles from 2035. India has additionally set a goal of 30% gross sales penetration of EVs in personal automobiles and 80% in two- and three-wheelers by 2030.
In 2019, the Nobel Prize in Chemistry was given to John B. Goodenough, M. Stanley Whittingham and Akira Yoshino for his or her contributions to the event of the lithium-ion battery. Lithium is utilized in electrical automobile batteries due to its properties— lightness and vitality density.
Quite a lot of vitality must be saved for machines that transfer, like automobiles.The battery should additionally not be impractically heavy and thus consuming much more vitality. Lithium turned splendid as this can be very vitality dense, storing quite a lot of vitality for a given weight, and likewise light-weight. Its lightness and reactivity additionally makes it splendid to facilitate the sleek stream of electrons from the unfavourable to the constructive electrode in a battery.
Today, lithium is an important a part of just about all electrical car batteries and people utilized in client electronics. While some new mixes like sodium ion batteries are being developed, lithium ion batteries are anticipated to stay the dominant battery chemistry because the EV trade burgeons to fulfill local weather targets and demand. For occasion, one of many bigger EV makers, Tesla’s Model S, accommodates 16 battery modules with a number of li-ion batteries in every module.
While lithium can be utilized in ceramics, in industrial grease, and within the pharmaceutical sector, its potential demand is anticipated to be largely pushed by batteries. McKinsey notes that in comparison with 2015, when nearly 30% of lithium demand was pushed by batteries, with ceramics and industrial materials accounting for the remainder, by 2030, batteries are anticipated to account for 95% of lithium demand. This is clear within the file excessive costs of lithium ($75,000/tonne) in 2022
Where are the world’s lithium reserves?
While lithium just isn’t briefly provide, the method of its extraction is time-and infrastructure-intensive. Lithium is at the moment extracted from two essential sources—onerous rock mines or as brine from salt flats and lakes, from the place it’s recovered utilizing evaporation tanks.
According to the U.S. Geological Survey, whereas recognized lithium sources worldwide stood at 89 million tonnes firstly of 2022, the reserves or mineable components of the sources stood at 22 million tonnes. Half of the world’s lithium sources are concentrated in Latin America (largely Bolivia, Chile, and Argentina), Australia, and China. In 2021, virtually 90% of lithium mining occurred in Chile, China, and Australia, with Australia main manufacturing.
As nations search to fulfill their targets for car fleet transitions and EV makers transfer to safe provide, the frenzy to search out lithium reserves has intensified. While counties with newly recognized lithium sources search methods for extraction, these with no home sources are trying to forge offers with companions or shopping for mines in different nations. Some automakers have or are planning to enter the mining of minerals like lithium and nickel themselves.
What do we all know thus far concerning the lithium sources inferred in Jammu and Kashmir?
Currently India is totally import-dependent with regards to lithium. While the Centre has launched incentives for battery manufacturing in India, uncooked supplies like lithium have thus far been imported. In 2020-21, India imported ₹173 crore price of lithium metallic and ₹8,811 crore price of lithium batteries. In 2022, between April and November alone, ₹164 crore price of metallic and ₹7,986 crore price of batteries had been imported. This implies that if the at the moment established lithium sources by the GSI are confirmed, India might see its dependence on imports go down considerably.
However, it is very important perceive the place the findings at the moment stand. The GSI has “inferred” that the deposits in Kashmir might maintain a whopping 5.9 million tonnes of lithium. This is the G3 stage of surveying. As per the United Nations Framework Classification (UNFC), a fundamental, reconnaissance survey is known as ‘G4’; the subsequent step is ‘preliminary exploration’, which is known as G3. Then comes normal exploration, or G2. And when portions related to a identified deposit “can be estimated with a high level of confidence”, the stage is known as G1.
According to the Ministry of Mines, the GSI has carried out 19 tasks within the final 5 years on “lithium and associated elements”. Of these, three of the tasks have progressed from the G4 to the G3 stage, and one to G2. These are within the Reasi district of J&Okay (the newly found estimate), and in Sirohi district and Nagaur district of Rajasthan. The one which has progressed to the G2 classification is the Rewat Hill block, additionally in Rajasthan.
Quite a lot of steps are concerned earlier than India might grow to be a producer of Lithium. First, the GSI must conduct additional exploration to find out if there are mineable reserves within the estimated 5.9 million sources in Jammu and Kashmir. This can be adopted by tendering and environmental clearances for mines. At current, India additionally doesn’t have lithium extraction applied sciences.
