In News:

  • NTPC Ltd, has invited Global Expression of Interest (EoI) to provide Hydrogen Fuel Cell (FC) based electric buses and electric cars in Leh and Delhi.
  • NTPC Ltd. Is India’s largest power producer and a central PSU under Ministry of Power.

Key takeaways:

  • The move to procure Hydrogen Fuel Cell based vehicles is first of its kind project in the country.
  • Under this project, a complete solution from green energy to the fuel cell vehicle would be developed.
  • The initiative has been undertaken with support of Ministry of New and Renewable Energy.
  • The initiative will also harness renewable energy for generation of hydrogen and develop its storage and dispensation facilities at Leh and Delhi.
  • The project aims at reducing carbon emissions from automobiles.

Important value additions:

Hydrogen Fuel

  • Hydrogen does not occur free in nature in useful quantities.
  • It can be made from natural gas or it can be made by passing electric current through water.
  • When hydrogen is burned, it only emits water vapour and carbon dioxide (CO2) is not produced. 
  • It is more efficient than internal combustion engine. 
  • However, manufacturing hydrogen fuel based vehicle is still expensive.

Topic: General Studies 2 & 3:

  • Effect of policies and politics of developed and developing countries on India
  • India’s Security challenges

At the edge of New Nuclear Arms Race

Context: US State department in its reports have stated that 

  • Russia has conducted nuclear weapons experiments 
  • China might be conducting nuclear tests with low yields at its Lop Nur test site

However, both Russia and China have rejected the U.S.’s claims

What does these allegations by US suggest?

  • Growing strategic competition between major powers 
  • Suggests the end of the CTBT that came into being in 1996 but has failed to enter into force even after a quarter century.

What is CTBT (Comprehensive Test Ban Treaty)?

  • CTBT is a global treaty that aims to ban all nuclear explosions across the world. 
  • It provides a legally binding norm against nuclear testing and was open for signature from 1996
  • However, the Treaty enters into force when 44 specific States signs and ratifies it. These States had nuclear facilities at that time & included India 
  • Till date, 36 have ratified the treaty. 
  • China, Egypt, Iran, Israel and the U.S. have signed but not ratified. 
  • India, North Korea and Pakistan have not yet signed the Treaty but all three have undertaken tests after 1996

Comprehensive Nuclear-Test-Ban Treaty Organization(CTBTO)

  • It was founded in 1996 to promote the Treaty so that it can enter into force. 
  • It also establishes a verification regime to monitor adherence to the Treaty.
  • The CTBT verification includes
    • International Monitoring System (IMS), 
    • International Data Centre (IDC)
    • On-site inspections (OSI).

Criticism of the Treaty

  • Defining the “comprehensive test ban” as a “zero yield” test ban that would prohibit supercritical hydro-nuclear tests but not sub-critical hydrodynamic nuclear tests. 
  • Anchoring the CTBT in a disarmament framework, as proposed by India, was not accepted
  • The treaty’s entry-into-force- provisions, which listed 44 countries by name, was protested by India as arm-twisting tactic and violation of Sovereign right of India
  • CTBTO is largely funded by US and unable to promote the treaty effectively.

Recent trends in Nuclear Arms

  • The New Strategic Arms Reduction Treaty (New START) that limits U.S. and Russian arsenals will expire in 2021 and US is not inclined to extend it
  • US has embarked on a $1.2 trillion nuclear modernisation plan spanning 30 years
  • China has also embarked on modernisation plan to enhance the lifespane of its smaller nuclear arsenal
  • Russia has responded by developing hypersonic delivery systems

Potential for a New Arms race

  • US wants to China into some kind of nuclear arms control agreement
  • But China is not interested by pointing to the fact that the U.S. and Russia still account for over 90% of global nuclear arsenals.
  • China also maintains that it will ratify CTBT only after the U.S.
  • This indicates the increasing divergence between US and China trade and technology disputes, militarisation in the South China Sea and coronavirus pandemic. 
  • U.S. could also be preparing the ground for resuming nuclear testing at Nevada indicating the beginning of new arms race


The developments between US and China could be the signs for a new cold war

Connecting the dots:

  • India’s Nuclear Doctrine
  • India’s attempt to become a member of Nuclear Supplier Group


Topic: General Studies 2 & 3:

  • Government policies and interventions for development in various sectors 
  • Indian Economy and issues relating to planning, mobilization, of resources 

Institutional challenges to migrants’ welfare

Context: The relief package announced by Union Government directed States to provide relief to Construction workers using provisions under Building and Other Construction Workers Act(BOCW), 1996.

What is BOCW Act?

  • The Act regulates the employment and conditions of service of building and other construction workers.
  • It provides for the levy and collection of cess at 1-2 % of the cost of construction, as the Central government may notify.
  • The cess is collected by the State governments and UTs.
  • It is utilised for the welfare of building and other construction workers by the respective State BOCW Boards.
  • Presently Rs 31,000 crore of funds is available with such welfare boards

Therefore, the basic framework of the governance is

  • States collect a cess from construction projects, register construction workers, and design schemes to use the funds collected for their welfare.

Constraints to provide assistance to casual workers during this pandemic

  1. Dependent on Formalisation: Only registered construction workers benefit from the welfare schemes
  2. Low worker registrations–  As of end-2018, according to Union Labour Ministry only 3.24 crore workers were registered across India, which represented about 60% of the construction workforce in India
  3. Low Awareness among the workers and their organisations about the benefits which can be availed through such legislation
  4. Limited State capacity for expenditure 
    • Chhattisgarh’s board would go bankrupt if they paid workers the central minimum daily NREGA wage of Rs 202 for the lockdown period
  5. Significant variations across states
    • Six states—Tamil Nadu, UP, MP, Odisha, Rajasthan and West Bengal—have 54% of the registered workforce, but only 32% of cess funds collected.
  6. Issues of interstate migrants
    • They constitute 42.7% of the urban construction workforce (Census 2001)
    • State BOCW Boards are reluctant to register migrants due to lack of political incentives

Way Ahead

  • Centre can use the expertise of the Central BOCW Advisory Committee to play a proactive role in coordinating amongst states
  • Centre can facilitate sharing beneficiary lists and funds between these states through interstate MoU
  • States—labour departments and welfare boards- need to improve the registration process. 
  • The quarantine camps for migrants are an opportunity to disseminate information, and even register such workers by utilizing the services of Civil Society groups.

Connecting the dots:

  • Real Estate (Regulation and Development) Act, 2016
  • Farmers distress during Pandemic
