Why in the News?

India’s energy security concerns have changed due to tensions in West Asia. A surprising reality is that Liquefied Petroleum Gas (LPG) has become a bigger risk than Liquefied Natural Gas (LNG). Earlier, crude oil and LNG were seen as the main concerns. Now, India imports 60% of its LPG, and about 90% of it passes through the Strait of Hormuz, making it highly vulnerable to disruptions at this key route.

Why is LPG a greater energy security concern than LNG for India?

1. Import Dependence: LPG import dependence stands at 60%, compared to LNG at ~50%.
2. Chokepoint Risk: Nearly 90% of LPG imports pass through the Strait of Hormuz, compared to ~60% for LNG.
3. Effective Share: LPG contributes 54% to India’s total energy supply dependence, while LNG contributes ~30%.
4. Household Dependency: LPG is the primary cooking fuel, affecting millions of households directly.
5. Limited Substitutability: LNG has alternatives (PNG, industrial fuels), while LPG substitution is limited in rural areas.

How do LPG and LNG differ in terms of production, storage, and distribution?

1. Chemical Nature: LPG consists of propane and butane; LNG is methane-based natural gas.
2. Storage Mechanism: LPG is stored in cylinders under moderate pressure; LNG requires cryogenic storage at -160°C.
3. Transport Infrastructure: LPG is transported via cylinders and road networks, LNG requires pipelines and regasification terminals.
4. Distribution Reach: LPG reaches remote areas without pipelines; LNG requires pipeline connectivity.
5. Safety Concerns: LPG is heavier than air and prone to explosion risks; LNG disperses faster.

What structural vulnerabilities exist in India’s LPG ecosystem?

1. High Import Exposure: Domestic LPG production meets only 40% of demand.
2. Geographic Concentration: Heavy reliance on a single maritime route (Hormuz).
3. Household Dependence: LPG is used by crores of households, making disruptions socially sensitive.
4. Infrastructure Limitation: Lack of PNG penetration in rural and semi-urban regions
5. Storage Constraints: Limited buffer storage compared to crude oil reserves.

Why is LNG relatively less vulnerable despite similar import dependence?

1. Diversified Sources: LNG imports come from Qatar, USA, and others, reducing concentration risk.
2. Flexible Usage: LNG is used in power generation, industries, and transport, allowing demand adjustments.
3. Pipeline Network: Increasing pipeline connectivity enables continuous supply.
4. Lower Household Dependence: LNG impacts industries more than households directly.
5. Strategic Buffering: LNG infrastructure allows storage in cryogenic tanks.

What is the government’s strategy to reduce LPG vulnerability?

1. Piped Natural Gas (PNG) Expansion: Promotes PNG to reduce LPG dependence.
   1. PNG is a natural gas, primarily methane, transported through a network of underground pipelines directly to residential, commercial, and industrial consumers, providing a continuous, safe, and eco-friendly fuel alternative for cooking and heating.
   2. It consists mainly of methane (CH4) and is considered a cleaner fuel.
   3. PNG is lighter than air, meaning it disperses easily in the event of a leak, making it safer than LPG.
   4. It is primarily used for domestic cooking, water heating, and in industrial settings like factories and restaurants.
2. Policy Push: Mandates PNG adoption in urban households.
3. Industrial Shift: Encourages industries to switch from LPG to LNG.
4. Supply Prioritization: Ensures LPG availability for households over commercial use.
5. Infrastructure Development: Expands pipeline networks and city gas distribution.

What are the broader implications of LPG vulnerability for India?

1. Energy Security Risk: High exposure to geopolitical disruptions.
2. Inflationary Pressure: LPG price shocks affect household budgets.
3. Social Impact: Cooking fuel disruption affects welfare schemes like Ujjwala.
4. Strategic Weakness: Over-reliance on a single chokepoint reduces resilience.
5. Policy Urgency: Requires diversification and infrastructure expansion. 

Conclusion

India’s energy security discourse must move beyond crude oil and LNG to address LPG vulnerabilities. Reducing import dependence, diversifying supply routes, and expanding PNG infrastructure are essential to ensure long-term resilience.

Why in the News?

India’s target of 300 GW solar capacity by 2030 has intensified land-use conflicts with agriculture, bringing agrivoltaics (AgriPV) into focus as a dual-use solution. The near doubling of PM-KUSUM allocation to ₹5,000 crore signals a shift toward farmer-centric solarisation. However, despite ~50 pilots, AgriPV faces scalability challenges due to high costs and regulatory gaps.

What is Agrivoltaics?

Agrivoltaics, also known as AgriPV or agrophotovoltaics (APV), is the simultaneous use of land for both solar energy generation and agriculture. Unlike traditional solar farms where panels are ground-mounted on bare land, AgriPV systems are designed to allow crops to grow, livestock to graze, or pollinator habitats to thrive underneath or between the solar panels.

AgriPV systems optimize land use by placing solar panels in specific configurations to balance electricity production with agricultural needs: 

1. Elevated (Stilted) Systems: Panels are mounted on tall structures (at least 2.1m to 4m high), providing enough clearance for tractors and farming machinery to operate underneath.
2. Inter-row (Ground-mounted) Systems: Panels are placed at lower heights but with wide spacing between rows to allow crops to be cultivated in the alleys between arrays.
3. Vertical Systems: Bifacial panels are mounted vertically (like walls), often at the periphery of fields, capturing sunlight primarily during sunrise and sunset while leaving the maximum amount of ground open for farming.
4. PV Greenhouses: Solar modules are integrated into the roof or exterior of a greenhouse to regulate internal temperature and power its climate control system.

How does Agrivoltaics address the land-energy-agriculture conflict?

1. Dual Land Use: Enables simultaneous electricity generation and crop cultivation on the same land parcel.
2. Land Efficiency: Reduces pressure on agricultural land compared to utility-scale solar requiring large tracts.
3. Food-Energy Balance: Maintains agricultural output while expanding renewable capacity.
4. Example: Elevated panel systems allow crops to grow underneath without disrupting farming operations.

What are the design and technological variations in AgriPV systems?

1. Elevated Systems: Panels mounted several metres above ground ensure adequate sunlight for crops.
2. Row-based Systems: Panels placed between crop rows minimise shading impact.
3. Vertical Systems: Upright panels reduce land obstruction and optimise sunlight distribution.
4. Greenhouse Integration: Panels installed on rooftops or walls support controlled farming environments.
5. Agro-climatic Adaptation: Crop selection varies across regions (e.g., tomato, onion, turmeric in MP; grapes, tomato in Maharashtra).

What economic benefits does Agrivoltaics provide to farmers?

1. Income Diversification: Farmers earn through electricity sales, leasing land, or revenue-sharing models.
2. Reduced Input Costs: Solar-powered irrigation lowers diesel dependency.
3. Risk Mitigation: Protection from extreme weather (hail, rainfall) stabilises farm output.
4. Example: PM-KUSUM promotes decentralised solar pumps and power plants to enhance farm incomes.

What environmental and productivity benefits does AgriPV offer?

1. Water Conservation: Reduced evapotranspiration due to panel shading improves soil moisture retention.
2. Climate Resilience: Protection against extreme weather events enhances crop stability.
3. Energy Sustainability: Supports clean energy generation aligned with net-zero goals.
4. Example: Partial shading benefits crops sensitive to excessive sunlight.

What are the key challenges limiting large-scale adoption?

1. High Capital Costs: Elevated structures and specialised mounting systems increase investment costs beyond conventional solar.
2. Regulatory Uncertainty: Lack of clarity in land classification, tariffs, and grid connectivity.
3. Design Gaps: Absence of standardised benchmarks for crop-panel configurations.
4. Institutional Barriers: Limited access to affordable finance and weak governance frameworks.
5. Data Deficit: Insufficient empirical evidence across agro-climatic zones.

What policy measures can accelerate Agrivoltaics deployment?

1. National Mission Integration: Inclusion in a proposed National Agri-Photovoltaics Mission under PM-KUSUM 2.0.
2. Financial Support: Viability Gap Funding (VGF) reduces capital cost burden.
3. State-level Interventions: Identification of clusters and streamlined approvals.
4. Capacity Building: Integration into farmer training and advisory systems.
5. Market Linkages: Clear tariffs and long-term purchase agreements ensure financial viability.

What is the current status of Agrivoltaics in India?

1. Pilot Projects: Around 50 installations across different regions.
2. Policy Recognition: Increasing mention in renewable energy discussions.
3. Scaling Constraint: Lack of commercial-scale implementation due to financial and regulatory barriers.

Conclusion

Agrivoltaics provides a viable pathway to reconcile India’s energy transition with agricultural sustainability. Scaling requires policy clarity, financial innovation, and region-specific design optimisation.
