  • Places in news: Carmichael Mine in Australia

    The Adani Group will begin exporting high quality, low sulphur coal from its Carmichael mine in Australia as early as this week, tapping a new multi-decade source to meet energy needs.

    Carmichael Mine

    • The Carmichael mine is located in the North Galilee Basin, more than 300 kilometers from the Queensland coastline and approximately 160 km north-west of Clermont in regional Queensland.
    • The Carmichael project, proposed in 2010, had provoked a sustained campaign by climate activists in Australia and other places globally, forcing banks and insurers not to work with the Adani group.
    • The conglomerate run by India’s second-richest man Gautam Adani has planned an initial production of 10 million tonnes a year from the mines in the Galilee Basin.
    • The Coal mined here has low sulfur content and high calorific value.

  • What is Irrecoverable Carbon?

    Researchers have identified and mapped 139 gigatonnes (Gt) of “irrecoverable carbon” in some of the world’s major forests and peatlands — including the Amazon and the Congo — to avoid catastrophic climate change.

    What is Irrecoverable Carbon?

    • The concept of ‘irrecoverable carbon’ was introduced in 2020.
    • All kinds of ecosystems — lush rainforest, muddy peatland, shady mangroves — contain eons of stored carbon, captured by photosynthesis.
    • Per square kilometer, the forests are among the most effective carbon stores in the world; but they’re also some of the most difficult to restore.
    • If destroyed, these ecosystems could take decades or centuries to regenerate.
    • In other words, the 139 gigatons of carbon contained in these areas are effectively irrecoverable if released due to anthropogenic activities.
    • Once released in air, it can be recovered but would take centuries to fully recover or naturally reintegrate.

    What is the new research?

    • In the new study, researchers have identified and mapped carbon reserves that are “manageable, are vulnerable to disturbance” and cannot be recovered by 2050.
    • They held study of peatlands of the Congo Basin and Northern Europe; and in North America, the mangrove swamps of the Everglades and old-growth forests of the Pacific Northwest.
    • 2050 has been set as the deadline for taking global carbon emissions to net zero in order for Earth to avoid warming at 1.5-2 degrees celsius above the pre-industrial levels.
    • To mitigate such a warming scenario, it is imperative to conserve the ecosystems with 139 Gt carbon.

    Key findings

    • Amazon is the biggest carbon sink on earth, holding 31.5 Gt irrecoverable carbon.
    • Brazil has the second-largest irrecoverable carbon reserves, after Russia that holds 23 per cent of the total irrecoverable carbon outlay in the world.
    • The second-largest reserve of carbon, at 132 Gt, comprise the islands of Southeast Asia, with their equatorial rainforests.
    • The Congo basin is the third-largest hotspot of irrecoverable carbon with over 8 Gt of carbon reserves, according to the study.
    • Australia, which has become a hotspot for wildfires, is home to 2.5 per cent of the world’s carbon reserve along its coastal mangroves and forests in the southeast and southwest.

    Why conserve these forests?

    • These regions are already being ravaged by wildfires and exploited for resources by mining and oil industries.
    • Since 2010, agriculture, logging and wildfire have caused emissions of at least 4 Gt of irrecoverable carbon.

  • Jaitapur Nuclear Power Project

    If built on time, Jaitapur Project in Maharashtra would be the largest nuclear power generating station in the world by net generation capacity, at 9,900 MW.

    Jaitapur Nuclear Power Project

    • Jaitapur Project is a proposed nuclear power plant in India.
    • The power project is proposed by Nuclear Power Corporation of India (NPCIL) and would be built at Madban village of Ratnagiri district in Maharashtra.
    • It is being built with technical cooperation from France.

    Project description

    • It is proposed to construct 6 European Pressurized Reactors designed and developed by Framatome (former Areva) of France, each of 1650 MW, thus totaling 9900 MW.
    • These are the third generation pressurized water reactors (PWR).
    • The cost of building the plant is about ₹20 crore (US$2.7 million) per MW electric power compared with ₹5 crore (US$660,000) per MW electric power for a coal power station.
    • A consortium of French financial institutions will finance this project as a loan. Both French and Indian government will give sovereign guarantee for this loan.

    Issues with the project

    (I) Liability for nuclear damage

    • The lack of clarity on the Civil Liability for Nuclear Damage Bill 2010 passed in Indian Parliament in August 2010 is a hurdle in finalizing deal.
    • This Civil Liability for Nuclear Damage Bill 2010 has a clause that deals with the legal binding of the culpable groups in case of a nuclear accident.
    • It allows only the operator (NPCIL) to sue the manufacturers and suppliers. Victims will not be able to sue anyone.

    (II) Clearance issue

    • Environmental effects of nuclear power and geological issues have been raised by anti-nuclear activists of India against this power project.
    • Even though the Maharashtra state govt completed land acquisition in 2010, only few people had accepted compensation cheques.

    (III) Seismicity of the area

    • Since Jaitapur is a seismically sensitive area, the danger of an earthquake has been foremost on the minds of people.
    • According to the Earthquake hazard zoning of India, Jaitapur comes under Zone III. This zone is called the moderate Risk Zone and covers areas liable to MSK VIII.
    • The presence of two major creeks on the proposed site has been ignored while clearing the site.

    (IV) Nuclear waste disposal

    • It is not clear where the nuclear waste from the site will be shipped for recycling or removed for disposal.
    • The plant is estimated to generate 300 tonnes of used nuclear fuel each year.
