  • [18th April 2025] The Hindu Op-ed: Are Indian startups not scaling up on innovation?

    PYQ Relevance:

    [UPSC 2024] What are the challenges in the commercialisation and diffusion of indigenously developed technologies? Although India is second in the world in filing patents, still only a few have been commercialised. Explain the reasons behind this less commercialisation.

    Linkage: The challenge of scaling up the impact of innovation by focusing on the commercialisation of patents, which is a crucial aspect for startups aiming to grow.

     

    Mentor’s Comment:  Startups in India have seen significant growth, especially with government initiatives like Startup India. However, Union Minister highlighted that many of these startups are focusing on repetitive ideas, like grocery delivery, rather than pushing the boundaries of innovation. He emphasized the need for more groundbreaking, science-based solutions to address broader challenges and drive sustainable growth.

    Today’s editorial looks at startups in India, focusing on factors that help them grow, challenges like lack of innovation and funding, and the need to move beyond grocery delivery for long-term success.. This content would help in GS paper 3 mains.

    _

    Let’s learn!

    Why in the News?

    Recently, at the Startup Mahakumbh in New Delhi, Union Commerce and Industry Minister Piyush Goyal said that many startups are not focusing enough on real innovation and are mostly sticking to ideas like grocery delivery.

    What challenges do deep tech startups in India face when it comes to scaling up?

    • High Initial Capital Requirement: Deep tech startups, especially in sectors like AI, biotech, or semiconductors, require significant funding in the early stages for R&D and prototyping. Eg: A startup working on quantum computing may need years of research before any commercial product is viable.
    • Lack of Follow-up Funding: Government seed funds like the Startup India Seed Fund provide limited support (~₹50 lakh), but large-scale funding is often unavailable, especially from domestic sources. Eg: A robotics startup may struggle to find Series A or B investors willing to back them after the seed stage.
    • Longer Time-to-Market and Uncertain Returns: Deep tech innovations take longer to reach the market and generate revenue, which deters many investors focused on quick returns. Eg: Healthtech firms developing diagnostic devices may take years to pass regulatory approvals before commercialization.

    Why is private sector follow-up funding considered crucial after initial government support for startups?

    • Bridges the Capital Gap: Government funds are limited and mainly support early-stage needs. Scaling requires much higher investment. Eg: A biotech startup receiving ₹50 lakh from a seed fund may need ₹10 crore for clinical trials.
    • Enables Long-Term Growth: Startups need sustained funding over multiple stages (Series A, B, etc.) to expand, hire talent, and enhance products. Eg: An electric mobility startup may require continuous investment to build charging infrastructure.
    • Signals Market Validation: Private investment shows that the startup idea has commercial potential, encouraging more stakeholders to engage. Eg: A deep tech startup attracting VC funding is more likely to gain customer and partner interest.
    • Brings Strategic Guidance and Networks: Private investors often provide mentorship, access to global markets, and business connections. Eg: A startup funded by a top VC firm might get access to international accelerator programs.
    • Reduces Dependence on Government: Encourages a self-sustaining innovation ecosystem and reduces reliance on public funds. Eg: Startups backed by private capital scale faster without waiting for bureaucratic processes.

    How do venture capitalists define innovation while deciding to invest in a startup?

    • User Impact and Experience: VCs assess whether the product/service offers a significant improvement in user experience or solves a real problem. Eg: A fintech app that reduces loan approval time from days to minutes is seen as innovative.
    • Market Potential and Demand: Innovation must address a need in a large or fast-growing market to be attractive to investors. Eg: An edtech startup targeting affordable online education in Tier-II/III cities taps into a large unmet demand.
    • Sustainable Competitive Advantage: Startups should have something unique that competitors can’t easily copy, like patents or proprietary tech. Eg: A healthtech startup with patented diagnostic AI software has a stronger edge.
    • Commercial Viability: Innovation must eventually lead to profitability and returns. VCs look for feasible business models. Eg: A SaaS platform with recurring revenue from subscriptions is more viable than a one-time product sale model.
    • Scalability and Replicability: The innovation should be scalable across geographies or customer segments. Eg: A logistics startup using AI route optimization can be scaled across different cities and industries.

    Which factors have contributed to the rise in the number of startups under the Startup India initiative?

    • Policy Support and Government Incentives: Multiple ministries and state governments have launched startup-friendly policies, funding schemes, and incubation support. Eg: The Startup India Seed Fund Scheme provides up to ₹50 lakh for early-stage startups.
    • Improved Access to Funding: Capital inflow through both equity and debt has increased, with growing interest from banks and private investors. Eg: SIDBI’s Fund of Funds supports venture capital firms that, in turn, invest in Indian startups.
    • Changing Mindset and Entrepreneurial Culture: A cultural shift among youth toward entrepreneurship, driven by success stories and digital exposure. Eg: Companies like Flipkart and Freshworks have inspired a new generation to build their own ventures.

    Where does India lag behind in comparison to countries like China and the U.S. in building a thriving startup ecosystem?

    • Lower Per Capita Income and Consumption Capacity: India’s lower GDP per capita limits domestic consumer spending, which affects the growth of digital and tech-driven startups. Eg: India’s per capita GDP is around $3,500, while China’s is over $12,000—boosting China’s digital economy faster.
    • Limited Domestic Risk Capital Availability: India relies heavily on foreign capital for startup funding, unlike the U.S. or China, which have strong domestic investor bases. Eg: Most VC funding in India comes from the U.S., while China has state-backed venture funds.
    • Bureaucratic Hurdles and Complex Regulations: Regulatory bottlenecks and lack of smooth implementation hinder startup operations and scalability. Eg: Despite policy support, startups still face delays in government clearances and compliances.

    Way forward: 

    • Strengthen Domestic Funding Ecosystem: Promote domestic VC funds, corporate venture arms, and pension fund investments in startups to reduce dependency on foreign capital. Eg: Incentivize Indian institutional investors to back deep tech ventures.
    • Simplify Regulatory Processes: Establish single-window clearances and reduce compliance burdens to foster ease of doing business for startups. Eg: Fast-track approvals for sectors like biotech, fintech, and healthtech.

  • What is Flue Gas Desulphurisation (FGD)?

    Why in the News?

    The Union Environment Ministry’s 2015 policy mandating the installation of Flue Gas Desulphurisation (FGD) equipment in all of India’s 537 coal-fired plants has been scrutinised by a recent study commissioned by the Office of the Principal Scientific Adviser.

    Flue Gas Desulphurisation (FGD)

    About Flue Gas Desulphurisation (FGD) in Power Plants

    • FGD is used to remove sulfur dioxide (SO₂) from flue gases in coal-fired power plants.
    • The process involves passing exhaust gases through a scrubbing system using absorbents like ammonia, sodium sulfite, or limestone.
    • Methods:
      • Wet Limestone Scrubbing: Gases pass through a scrubber tower with a slurry of water and limestone.
      • Dry Sorbent Injection: Uses a dry alkaline agent to neutralize SO₂.
      • Sea Water-Based Systems: Utilizes seawater’s natural alkalinity to absorb SO₂.
    • FGD can remove up to 95% of sulfur dioxide, reducing SO₂ emissions significantly.
    • Reduces sulfur emissions, major contributors to acid rain and air pollution.
    • FGD Gypsum, a byproduct, can be used in industries like cement manufacturing.

    Recent Study on FGD in Power Plants

    • A study by NIAS critiques India’s FGD policy, recommending limited FGD installations for plants using imported or high-sulfur coal.
    • 92% of coal in Indian plants has low sulfur content (0.3%-0.5%), meaning FGD may not significantly improve local air quality.
    • Widespread FGD installation could increase power and water consumption, and result in 69 million tonnes of additional CO₂ emissions by 2030.
    • Removing SO₂ (cooling agent) while increasing CO₂ emissions may accelerate climate change.
    • Recommendations: Installing electrostatic precipitators (₹25 lakh per MW) can reduce 99% of particulate matter (PM), offering a more cost-effective and impactful solution.
    [UPSC 2024] According to the Environmental Protection Agency (EPA), which one of the following is the largest source of sulphur dioxide emissions?

  • History and Evolution of the Office of Governor

    Why in the News?

    The recent Supreme Court verdict on the powers of the President and Governors regarding assent to Bills under Articles 201 and 200 highlights the evolution of the office of the Governor and its changing role in India’s federal structure.

    Evolution of the Office of Governor:

    • Formal Establishment (1858): The office of the Governor was established under the Government of India Act of 1858, which transitioned administration from the East India Company to the British Crown. Governors acted as agents of the Crown and had significant powers in provincial administration.
    • Montagu-Chelmsford Reforms (1919): The GoI Act of 1919, under the Montagu-Chelmsford Reforms, aimed to increase Indian participation but kept the Governor central to governance, including vetoing Bills passed by legislative councils.
    • GoI Act of 1935: The GoI Act of 1935 gave provincial autonomy but retained the Governor’s discretionary powers, including vetoing Bills and withholding assent, signalling a transition toward more autonomy while maintaining significant Governor authority.
    • Post-Independence Transition (1947): As India moved toward independence, the India (Provisional Constitution) Order of 1947 modified the 1935 Act. It removed the phrase “in his discretion,” reducing the Governor’s discretionary powers and signalling a shift to a more symbolic and constitutional role.
    • Constituent Assembly Debates: It debated whether Governors should be elected or nominated. Concerns over separatism led to the decision that Governors would be nominated by the President to maintain unity and strengthen ties with the Centre, especially after the partition.
    • Post-Independence Framework: Before Independence, various documents and political proposals, including the Commonwealth India Bill (1925) and the Nehru Report (1928), supported retaining the office of the Governor, inspired by the Westminster model of governance.

    Constitutional Role of the Governor:

    • Article 163: The Governor acts on the advice of the Council of Ministers headed by the Chief Minister, except in certain discretionary situations.
    • Ambedkar’s Views: Dr. B.R. Ambedkar advocated for limited use of discretionary powers, ensuring the Governor’s actions align with the advice of the ministers.
    • Article 200: The Governor must grant assent to Bills, but may withhold assent, reserve the Bill for the President, or return it for reconsideration. Ambedkar amended this in 1949 to ensure the Governor acts in alignment with the elected government.
    • Symbolic and Impartial Role: The Governor is expected to represent the Union, support democratic functioning, and remain non-interfering in day-to-day state affairs.
    • Discretionary Powers: The Governor’s discretion is limited to constitutional guidelines and should be used sparingly, ensuring the Governor’s role remains constitutional, not political.
    [UPSC 2017] In the context of Indian history, the-principle of ‘Dyarchy (diarchy)’ refers to:

  • [16th April 2025] The Hindu Op-ed: India, rising power demand and the ‘hydrogen factor’

    PYQ Relevance:

    [UPSC 2018] With growing energy needs should India keep on expanding its nuclear energy programme? Discuss the facts and fears associated with nuclear energy.

    Linkage: India growing energy needs and the role of a specific low-carbon source, which is relevant in the broader context of exploring other low-carbon alternatives like hydrogen for industrial use.

     

    Mentor’s Comment:  To achieve a net-zero economy, we need to significantly increase the use of electricity in various sectors. Currently, fossil fuels are used not only to generate electricity but also to provide heat and raw materials for industries. For example, carbon from coal is used in steel production, and hydrogen from natural gas is used to make ammonia for fertilizers. In the steel industry, hydrogen can replace carbon. So, a net-zero economy would involve using more electricity and hydrogen in industrial processes.

    Today’s editorial discusses the important role of hydrogen fuel in industries to help achieve a net-zero economy. This content is relevant for GS Paper 3 in the mains exam.

    _

    Let’s learn!

    Why in the News?

    To achieve a net-zero economy, which requires more use of hydrogen, hydrogen production and electricity storage need to work together efficiently.

    What is hydrogen’s role in achieving net-zero emissions, particularly in industry?

    • Replacement for Carbon in Steel-making: Hydrogen can replace carbon (from coal) to reduce iron ore in the steel industry, enabling low-emission steel production. Eg: Jindal Steel is implementing hydrogen-based Direct Reduced Iron (DRI) processes in its steel plants in Angul, India.
    • Feedstock for Fertilizer Industry: Hydrogen is used to produce ammonia, a key input for fertilizers. Currently sourced from natural gas, it can be replaced with green hydrogen to cut emissions. Eg: Green hydrogen is being utilized in ammonia plants to decarbonize agricultural inputs. ​
    • Energy Carrier for Hard-to-Electrify Sectors: Hydrogen provides high-temperature heat and energy where direct electrification is not feasible, such as in cement and chemical industries. Eg: Hydrogen-powered kilns are being explored in cement production to reduce carbon emissions.​
    • Storage and Use of Surplus Renewable Energy: Surplus electricity from solar and wind can produce hydrogen via electrolysis, storing energy for industrial use. Eg: Electrolysers operating during solar peak hours produce hydrogen for later industrial use, aiding in grid balancing.​
    • Enabler of Circular and Low-Carbon Economy: Hydrogen supports closed-loop industrial systems and enables the transition to a low-carbon industrial ecosystem. Eg: Industrial parks are utilizing shared hydrogen infrastructure for multiple processes, promoting sustainability.​

    Why is nuclear vital for meeting India’s future power needs?

    Reason Explanation Example
    Reliable Base Load Power Provides continuous, 24/7 electricity, unlike intermittent solar and wind. Kakrapar Atomic Power Station in Gujarat supplies stable power, reducing reliance on coal.
    Low-Carbon Energy Source Emits very low greenhouse gases, essential for India’s net-zero targets. One nuclear plant avoids millions of tonnes of CO₂ compared to coal-fired plants of similar capacity.
    High Energy Density & Land Efficiency Produces large energy output from a small land area, ideal for land-scarce regions. A 700 MW PHWR needs far less space than an equivalent-capacity solar farm.
    Energy Security & Indigenous Capability Indigenous PHWR tech reduces import dependency, boosting self-reliance. Bharat Small Reactors (BSRs) initiative supports local nuclear plants for industrial use.
    Supports Industrial & Developmental Goals Meets growing electricity demand from industries, EVs, and digital infrastructure. Indian Railways is exploring nuclear power to sustainably meet part of its future electricity requirements.

    How do electrolysers help avoid flexing nuclear plants?

    • Utilize Surplus Electricity: Electrolysers consume excess electricity (especially during low demand or high renewable generation), preventing wastage. Eg: During off-peak hours, nuclear plants continue running at full power, and electrolysers convert surplus electricity into hydrogen.
    • Avoids Technical Challenges of Flexing Nuclear: Flexing (ramping up/down) nuclear plants is technically complex and not cost-effective. Electrolysers provide a flexible load instead. Eg: Countries like France prefer operating electrolysers over reducing nuclear output to balance grid load.
    • Reduces Need for Electricity Storage: By producing hydrogen instead of storing electricity in batteries, electrolysers lower reliance on expensive energy storage systems. Eg: A hybrid system with electrolysers and minimal battery backup is more economical than large-scale battery-only setups.
    • Creates Industrial Value from Surplus Power: Hydrogen produced by electrolysers can be used directly in industries like steel and fertilizer, giving value to otherwise curtailed energy. Eg: Surplus nuclear power at night is used to produce hydrogen for ammonia production, supporting the fertilizer sector.
    • Maintains Economic Efficiency of Nuclear Plants: Electrolysers help nuclear plants operate at full capacity, maximizing their economic return by avoiding part-load inefficiencies. Eg: Operating a 700 MW PHWR continuously at full load ensures lower per-unit cost and higher return on investment.

    Which policy changes improve the synergy between hydrogen generation and electricity storage?

    • Redefining Green Hydrogen as Low-Carbon Hydrogen: Broaden the definition to include hydrogen from nuclear and other low-carbon sources, not just solar/wind. Eg: If hydrogen from nuclear is included under “low-carbon,” it becomes eligible for government incentives and boosts its adoption.
    • Integrated Planning for Hydrogen and Storage Infrastructure: Encourage policies that promote co-location of electrolysers and battery storage to optimize power use. Eg: A hybrid facility that stores electricity when prices are low and runs electrolysers when solar/wind generation is high.
    • Incentives for Grid-connected Electrolyser Projects: Offer financial and regulatory support to industries that install grid-responsive electrolysers. Eg: Time-of-use electricity pricing policies that make hydrogen production cheaper during surplus power hours.
    • Mandating Industrial Use of Green/Low-Carbon Hydrogen: Introduce mandates for sectors like steel and fertilizers to shift partially to low-carbon hydrogen. Eg: A policy requiring steel plants to use 10% green hydrogen by 2030 encourages investment in electrolysers.
    • Support for Hybrid Hydrogen-Storage Business Models: Develop regulations that allow joint operation and revenue models for battery storage and hydrogen production. Eg: A private power developer earns incentives both for stabilizing the grid (via battery) and producing green hydrogen.

    Where has the NPCIL planned the deployment of new 700 MW Pressurized Heavy Water Reactors (PHWRs) in India?

    • Kakrapar Atomic Power Station (KAPS), Gujarat: KAPS is already home to two operational 700 MW PHWR units (KAPS-3 and KAPS-4), with plans for further expansion. The successful commissioning of these units has demonstrated the robustness of the 700 MW PHWR design.
    • Rajasthan Atomic Power Station (RAPS), Rajasthan: RAPS-7, India’s third indigenously designed 700 MW PHWR, achieved first criticality in September 2024. RAPS-8 is under construction and is expected to be operational by 2026.
    • Gorakhpur Haryana Anu Vidyut Pariyojana (GHAVP), Haryana: GHAVP is set to host four 700 MW PHWR units, with GHAVP-1 and GHAVP-2 under construction and expected to be operational by 2028 and 2029, respectively.

    Way forward: 

    • Accelerating Infrastructure Development: India should fast-track the construction of 700 MW PHWR units across key sites like KAPS, RAPS, and GHAVP, ensuring timely completion to meet future energy demands and reduce reliance on coal.
    • Policy Support for Hydrogen and Nuclear Synergy: Government policies should incentivize the integration of nuclear power with hydrogen production, promoting hybrid systems that can utilize surplus nuclear energy for green hydrogen generation and enhance industrial decarbonization efforts.
