    Big Lithium find: Risks and Rewards

     

  • Places in news: Darvaza Gas Crater

    Turkmenistan President has ordered experts to find a way to extinguish a fire in a huge natural gas crater, the Darvaza gas crater also known as the ‘Gateway to Hell’.

    Darvaza Gas Crater

    • Located in the Karakum desert, 260 kilometres away from Turkmenistan’s capital, Ashgabat, the crater has been burning for the last 50 years.
    • The crater is 69 metres wide and 30 metres deep.
    • While the details of the origin of the crater are contested but it has been said that the crater was created in 1971 during a Soviet drilling operation.
    • In 1971, Soviet geologists were drilling for oil in the Karakum desert when they hit a pocket of natural gas by mistake, which caused the earth to collapse and ended up forming three huge sinkholes.

    Why is it flamed?

    • This pocket of natural gas contained methane, hence to stop that methane from leaking into the atmosphere, the scientists lit it with fire, assuming the gas present in the pit would burn out within a few weeks.
    • The scientists seemed to have misjudged the amount of gas present in the pit, because the crater has been on fire for five decades now.

    A popular tourist attraction

    • The crater has become a significant tourist attraction in Turkmenistan.
    • In 2018, the country’s president officially renamed it as the “Shining of Karakum”.

    Why did Turkmenistan order to extinguish it?

    • Calling it a human-made crater, it has negative effects on both environment and the health of the people living nearby.
    • It also ends up losing valuable natural resources for which could fetch significant profits.

    How harmful are methane leaks?

    • Methane is the primary contributor to the formation of ground-level ozone, a hazardous air pollutant and greenhouse gas, exposure to which causes 1 million premature deaths every year.
    • Methane is also a powerful greenhouse gas. Over a 20-year period, it is 80 times more potent at warming than carbon dioxide.

    Back2Basics: TAPI Gas Pipeline

    • The Turkmenistan–Afghanistan–Pakistan–India (TAPI) Pipeline is a natural gas pipeline being developed with the participation of the Asian Development Bank.
    • It will be a 1,814km trans-country natural gas pipeline running across four countries.
    • It will transport natural gas from the Galkynysh Gas Field in Turkmenistan through Afghanistan into Pakistan and then to India.
    • The plan for the TAPI project was originally conceived in the 1990s to generate revenue from Turkmenistan’s gas reserves by exporting natural gas via Afghanistan to Pakistan and India.
    • Construction on the project started in Turkmenistan on 13 December 2015, work on the Afghan section began in February 2018, and work on the Pakistani section was planned to commence in December 2018.
    • Presently, the construction work has been stalled due to terror activities of Taliban in Afghanistan since few years.

  • [pib] Hybodont Shark fossils found in Jaisalmer

    In a rare discovery, teeth of new species of Hybodont shark of Jurassic age have been reported for the first time from Jaisalmer by a team of officers from the Geological Survey of India (GSI).

    Hybodont Shark

    • Hybodonts, an extinct group of sharks, was a dominant group of fishes in both marine and fluvial environments during the Triassic and early Jurassic time.
    • However, hybodont sharks started to decline in marine environments from the Middle Jurassic onwards until they formed a relatively minor component of open-marine shark assemblages.
    • They finally became extinct at the end of the Cretaceous time 65 million years ago.

    Significance of the fossil

    • The newly discovered crushing teeth from Jaisalmer represents a new species named by the research team as Strophodusjaisalmerensis.
    • These sharks have been reported for the first time from the Jurassic rocks (approximately, between 160 and 168 million years old) of the Jaisalmer region of Rajasthan.
    • The genus Strophodus has been identified for the first time from the Indian subcontinent and is only the third such record from Asia, the other two being from Japan and Thailand.
    • It opens a new window for further research in the domain of vertebrate fossils.

    • The domestic exploration push comes at a time when India has stepped up its economic offensive against China, a major source of lithium-ion energy storage products being imported into the country.
    • The Marlagalla-Allapatna area is seen as among the most promising geological domains for potential exploration for lithium and other rare metals.

    What lies ahead?

    • India is seen as a late mover in attempts to enter the lithium value chain, coming at a time when EVs are predicted to be a sector ripe for disruption.
    • 2021 is likely to be an inflexion point for battery technology – with several potential improvements to the li-ion technology, and alternatives to this tried-and-tested formulation in advanced stages of commercialization.

    Back2Basic: Li-Ion battery

    • Whittingham developed the first functional lithium-ion battery in 1976, Goodenough brought in a major improvement in 1980, while Yoshino made the first practical-use lithium-ion battery in 1985.
    • Commercially manufactured lithium-ion batteries, based on what Yoshino had developed, made their first appearance in 1991.

    Its’ working

    • Batteries convert chemical energy into electricity.
    • A battery comprises two electrodes, a positive cathode and a negative anode, which is separated by a liquid chemical, called an electrolyte, which is capable of carrying charged particles.
    • The two electrodes are connected through an electrical circuit.
    • When the circuit is on, electrons travel from the negative anode towards the positive cathode, thus generating an electric current, while positively charged ions move through the electrolyte.
