    [UPSC 2020] Do you think India will meet 50 percent of its energy needs from renewable energy by 2030? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective? Explain.

     

    Linkage: The transition is inherently linked to climate change mitigation, conservation, and pollution control. Recent topics include CCUS, India’s updated climate commitments (NDCs), and balancing development with environmental protection.

    Why in the News?

    The successful trial of India’s first hydrogen-powered coach at the Integral Coach Factory (ICF), Chennai, in July 2025 marks a critical milestone in the Indian Railways’ decarbonisation strategy.

    Introduction:

    With a target of achieving net-zero carbon emissions by 2030, four decades ahead of India’s national goal, the Indian Railways is reshaping its energy, infrastructure, and financing architecture to become a global model for sustainable mobility.

    Carrying over 24 million passengers and 3 million tonnes of freight daily, this transition directly supports India’s nationally determined contributions (NDCs) under the Paris Agreement.

    India’s Energy Transition Context (2025):

    • As of June 2025, over 50% of India’s installed power capacity (476 GW total) comes from non-fossil sources, five years ahead of its 2030 Paris target.
    • Renewables: Solar (110.9 GW) and wind (51.3 GW) continue rapid expansion; nuclear capacity adds 8.8 GW.
    • Electrification: 100% village electrification achieved, with household access nearing universality.
    • Challenges:
      • Fossil fuel reliance: Coal consumption rose to 21.98 EJ in 2023, up from 6.53 EJ in 1998, with petroleum demand increasing in agriculture.
      • Energy equity gaps: Access to clean cooking fuel remains uneven; LPG adoption under PM Ujjwala Yojana suffers from affordability constraints.

    Green Transition and Decarbonisation Efforts in Railways:

    1. Network Electrification: Over the past decade, the Indian Railways has electrified nearly 45,000 km of its broad-gauge network, bringing 98% of routes under electrification. This has drastically reduced diesel use and greenhouse gas emissions, marking a major shift toward energy efficiency.
    2. Renewable Integration: Renewable power capacity has reached 756 MW (553 MW solar, 103 MW wind, 100 MW hybrid). Over 2,000 stations and offices are now powered by solar energy, reducing grid dependence and promoting clean traction power.
    3. Net-Zero Buildings: Several railway complexes and offices have received the “Shunya” Net-Zero label from the Bureau of Energy Efficiency (BEE) for achieving energy neutrality and carbon efficiency.
    4. Hydrogen for Heritage Initiative: This flagship programme aims to deploy 35 hydrogen-powered train units, with the first prototype hydrogen coach rolled out in 2025, representing a major milestone in green rail mobility.
    5. Freight and Efficiency Gains: Dedicated Freight Corridors (DFCs) are projected to prevent 457 million tonnes of CO₂ emissions over the next 30 years. The goal is to increase the rail freight modal share from 27% to 45% by 2030, cutting road-sector emissions.
    6. Complementary Actions: Railways are also expanding biofuel blending, green building construction, and rolling stock modernisation with regenerative braking and energy-efficient locomotives.

    Hydrogen Coach Technology and Innovation:

    1. Fuel-Cell Mechanism: The hydrogen coach uses fuel-cell technology to generate electricity through a chemical reaction between hydrogen and oxygen, producing only water vapour as the by-product, ensuring zero tailpipe emissions.
    2. Operational Context: Designed for non-electrified heritage routes where full electrification is uneconomical, these trains combine lightweight coach design, aerodynamic efficiency, and AI-based traction optimisation to minimise operational costs.
    3. Global Positioning: With this innovation, India joins the league of nations such as Germany and Japan that are pioneering hydrogen-based railway systems as part of a wider low-carbon transport transition.

    Climate Finance and Institutional Architecture:

    1. Green Financing Framework: India has issued ₹58,000 crore worth of sovereign green bonds since FY2023, with ₹42,000 crore specifically allocated to electric locomotives, metros, and suburban rail projects.
    2. IRFC’s Role: The Indian Railway Finance Corporation (IRFC) pioneered a $500 million green bond in 2017 for refinancing electric locomotive projects, and in 2025 extended a ₹7,500 crore loan to NTPC Green Energy to support renewable generation for traction power.
    3. Multilateral Support: The World Bank’s $245 million Rail Logistics Project (2022) aims to decongest corridors and reduce transport-sector emissions through improved infrastructure efficiency.
    4. Institutional Integration: Together, these instruments embed climate goals into national capital budgeting, aligning transport infrastructure with India’s low-carbon growth pathway.

    Policy and Operational Priorities:

    1. Renewable Power Procurement: Long-term contracts with solar and wind producers are critical to ensure that electrified routes are powered by green energy rather than coal-based electricity.
    2. Green Mobility Hubs: Major stations are being redesigned as multi-modal eco-hubs with integration of EV charging stations, e-buses, and bicycle-sharing systems.
    3. Freight Decarbonisation: Emphasis on electric, LNG, and hydrogen-fuelled trucks for last-mile logistics, reducing the carbon footprint beyond rail.
    4. Rolling Stock Modernisation: Accelerated adoption of lightweight aluminium coaches, regenerative braking, and energy-efficient locomotives.
    5. Behavioural Initiatives: Introduction of green certification for trains, carbon labelling of freight, and public awareness programmes to mainstream sustainability.

    Projected Outcomes by 2030:

    1. Net-Zero Achievement: The Indian Railways aims to achieve net-zero carbon emissions by 2030, preventing an estimated 60 million tonnes of CO₂ annually, equivalent to removing 13 million cars from the roads.
    2. Economic Impact: Fuel cost savings from electrification and energy efficiency could exceed ₹1 lakh crore by 2030, freeing capital for further green infrastructure.
    3. Global Benchmark: The Indian Railways is positioned to become the world’s first large rail system to achieve net-zero operations, setting a global precedent for state-run low-carbon transport.

    Conclusion:

    1. The hydrogen-powered coach exemplifies the synergy of technology, finance, and policy in achieving sustainable national mobility.
    2. The Railways’ green transformation is both an environmental necessity and a strategic innovation model for the developing world.
    3. Its successful execution will anchor India’s net-zero and green industrialisation vision, proving that scale and sustainability can coexist profitably.

    RRI technique yields Certified Randomness with one Qubit

    Prelims Only | Science Tech | Mains Paper 3: Achievements Of Indians In S&T

    Why in the News?

    The Raman Research Institute (RRI), Bengaluru team has mastered the Leggett–Garg Inequality (LGI)–based quantum randomness certification technique.

    What is Quantum Randomness?

    • Overview: Quantum randomness means true unpredictability, results that even nature or science cannot predetermine. They arise from the laws of quantum physics, not from computer programs or hidden causes.
    • Ordinary Computers: In normal computers, random numbers come from formulas called pseudorandom generators. They look random but can be predicted if someone knows the starting point (the “seed”).
    • Quantum Systems: In quantum physics, when you measure something tiny, like the spin of an electron or the path of a light particle (photon), the result is decided only at the moment of measurement. No one, not even nature, “knows” the answer before that.
    • Why it Matters: True randomness is important for data security, safe online transactions, scientific research, and encryption, where predictability can lead to hacking or errors.

    What has RRI achieved?

    • Discovery: Scientists at the Raman Research Institute (RRI), Bengaluru, led by Prof. Urbasi Sinha, have found a way to create and verify true quantum randomness using a regular cloud-based IBM quantum computer.
    • Why it’s Important: Earlier, proving quantum randomness needed expensive lab equipment. Now it can be done remotely and cheaply, accessible to anyone with internet and quantum cloud access.
    • How it Works: The RRI team used just one qubit (the quantum version of a computer bit) to show that the randomness came from quantum effects, not from hardware noise or computer errors.
    • Key Finding: This demonstrates that even imperfect quantum computers can still generate trustworthy and verifiable random numbers, a capability that classical computers cannot achieve.

    What is the Leggett–Garg Inequality (LGI)–Based Test?

    • Basic Idea: The Leggett–Garg Inequality (LGI) is a scientific test that checks whether something behaves like everyday objects (predictable) or like quantum systems (unpredictable).
    • How it was Used: The RRI scientists measured one qubit at three different times to see if its behavior followed normal physics or quantum rules.
    • Two Conditions Checked:
      • LGI Violation – confirmed the qubit was behaving in a truly quantum way.
      • No Signalling in Time – ensured that each measurement was independent and not influenced by the previous one.
    • Result: Meeting both tests proved that the numbers generated were certified as truly random, coming purely from quantum physics, not from any background noise or interference.

    Real-life Applications:

    • Cybersecurity: Such randomness can make unbreakable encryption keys, protecting sensitive data from hackers.
    • Cloud Computing: People using quantum computers online can now access trusted random numbers for research or secure systems anywhere in the world.
    • Testing Quantum Machines: Helps scientists check the quality of quantum computers, since randomness shows how genuinely quantum the machine is.
    • Better Science: Used in simulations, artificial intelligence, and data analysis where unpredictability makes results more reliable.
    • Big Scientific Message: Confirms that the quantum world is truly uncertain, proving one of the most fascinating truths of modern science, that randomness is built into nature itself.
    [UPSC 2025] Consider the following statements:

    I. It is expected that Majorana 1 chip will enable quantum computing.

    II. Majorana 1 chip has been introduced by Amazon Web Services (AWS).

    III. Deep learning is machine learning.
