Oil and Energy Security: Navigating the Clean Energy Transition

Oil remains central to global energy security despite growing momentum toward decarbonization. Its importance stems from economic affordability, supply reliability, geopolitical influence, and industrial versatility, while simultaneously playing a paradoxical yet critical role in facilitating the clean energy transition through bridging fuels, technological enablement, and infrastructure adaptation.

Why Oil is Critical for Energy Security

Conceptual Framework: The 4A Model and Sovereignty-Robustness-Resilience Perspective

Energy security is fundamentally defined through the 4A Framework comprising:

• Availability: Sufficient energy resources to meet national demand
• Accessibility: Physical and economic capacity to obtain resources
• Affordability: Cost competitiveness relative to alternative energy sources
• Acceptability: Environmental and social sustainability standards

The Sovereignty-Robustness-Resilience Perspective developed by Cherp and Jewell provides comprehensive analytical depth:

• Sovereignty: Political control and strategic autonomy over energy resources and infrastructure
• Robustness: Physical and institutional infrastructure resilience against disruptions
• Resilience: System flexibility and adaptive capacity responding to supply shocks and market volatility

Oil satisfies all three dimensions uniquely, making it indispensable for contemporary energy security strategies.

India’s Strategic Oil Dependency and Portfolio Diversification

India exemplifies oil’s centrality to energy security through multiple vulnerabilities and strategic responses:

• Import Dependency: Over 85% of crude oil imported (2024-2025)
• Reserve Position: 651.8 MMT total reserves as of January 2025
• Strategic Reserves: 5.33 million metric tonnes SPR capacity providing crucial supply buffers

Strategic Petroleum Reserve deployment demonstrates the Portfolio Theory of Energy Security, applying mean-variance optimization to minimize risk exposure:

• Historical Accumulation: Capacity built since 1999 to shield against geopolitical shocks
• Supply Diversification: Expanded from 27 supplier countries (2022) to 40 countries (2025)
• Geographic Rebalancing: West Asian dependency reduced from over 60% to below 45%
• Russian Pivot: Imports surged from 2% pre-Ukraine (2021) to 35-40% (2025), filling Libyan and Iranian supply gaps

This deliberate diversification reduces vulnerability to single-source disruptions, exemplifying the Portfolio Theory’s practical application in national energy policy.

Geopolitical Disruption Risks and OPEC+ Dynamics

Historical and contemporary supply disruptions underscore oil’s strategic vulnerability:

• 1973 Arab Oil Embargo: Quadrupled crude prices within months, exposing Western OPEC dependency and prompting SPR creation
• 2022 Russia-Ukraine War: Triggered Europe’s energy crisis with 60-90% price spikes in certain markets
• 2019 Saudi Aramco Attacks: Houthi drone strikes disrupted 5% of global supply temporarily
• Contemporary Vulnerabilities: Middle Eastern tensions involving Israel, Iran, and Yemen heighten supply risks

Critical Chokepoint Analysis:

• Strait of Hormuz: Transits 20% of global oil supply (approximately 20 million bpd)
• OPEC+ Spare Capacity: Roughly 3.5 million bpd primarily held by Saudi Arabia and UAE
• Iranian Output Equivalent: Potential Iranian disruption equals existing OPEC+ spare capacity, leaving minimal buffer for simultaneous multiple disruptions

Long-term Demand Projections and Persistent Hydrocarbon Dependence

The International Energy Agency’s 2025 World Energy Outlook presents contrasting scenarios:

• Current Policies Scenario (CPS): Oil demand rises from 100 million bpd (2024) to 113 million bpd (2050)—an 11% increase—without new climate policies
• Stated Policies Scenario (STEPS): Demand peaks around 102 million bpd by 2030, then declines to 97 million bpd by 2050
• Global Primary Energy Growth: Expected 25% increase by 2050 driven by AI technologies, Asian economic expansion, and rising living standards across 3 billion people

Petrochemical Feedstock Indispensability

Oil’s role extends critically beyond fuel to industrial feedstocks:

• Feedstock Types: Naphtha, ethane, LPG serving as raw materials
• Product Applications: Plastics, synthetic fibers, fertilizers, pharmaceuticals, chemicals, cosmetics, packaging materials
• Demand Trajectory: Non-energy petrochemical use continues growing through 2040 despite energy-use liquids declining from 2027
• Refinery Evolution: Refiners transitioning toward deeper downstream integration, petrochemical complexing, and specialty product development

This industrial dependence makes oil indispensable for economic functioning even as transport energy demand potentially plateaus.

Oil’s Role in the Clean Energy Transition

Paradoxically, the oil and gas industry serves simultaneously as both transition enabler and legacy infrastructure manager. The sector’s clean energy transition role manifests through three distinct pathways.

Pathway 1: Natural Gas as Transitional Bridge Fuel

Natural gas occupies a unique position in decarbonization strategies:

• Emission Reductions vs. Coal: 50% less COâ‚‚ per unit energy than coal
• Emission Reductions vs. Oil: 70% less COâ‚‚ per unit energy than crude oil
• Cleanest Fossil Fuel Classification: Significantly lower GHG intensity than alternatives

Bridge Fuel Theory Applications:

• Displacement Mechanics: Natural gas replaces higher-emission sources while renewable capacity scales
• US Case Study: American emissions fell sharply when natural gas-generated electricity displaced coal capacity
• LNG Intensity Advantage: Liquefied natural gas shows approximately 60% lower greenhouse gas intensity than coal
• Comparative Efficiency: Even comparing methane-intensive LNG with efficient coal plants, LNG remains 26% less GHG-intensive

Global Expansion Drivers:

• Capacity Growth: LNG capacity projected to surge 50% by 2030, reaching 880 billion cubic meters by 2035 and 1,020 bcm by 2050 under current policies
• Primary Driver: Explosive power sector demand from data centers, AI computing infrastructure, and industrial processes
• Regional Focus: Asia drives expansion as natural gas replaces coal dependency while providing dispatchable backup for intermittent renewables

Critical Limitation: Infrastructure Resilience Gaps

The 2021 Texas Power Crisis revealed systemic vulnerabilities in natural gas transition strategies:

• Event Overview: Winter Storm Uri caused 40% of grid capacity to fail during February 2021
• Natural Gas Failures: Five times more natural gas infrastructure capacity failed than wind turbines—primarily from freezing in production, processing, and transport facilities
• Consequential Impact: 4.5 million Texans lost power; at least 246 deaths recorded; economic damages exceeded $130 billion
• Prior Warning Ignored: 2011 weatherization recommendations went unimplemented by Texas energy operators
• Systemic Lesson: Natural gas cannot serve as reliable renewable backup without rigorous weatherization, maintenance standards, and regulatory enforcement

This demonstrates that bridge fuel strategies require comprehensive infrastructure resilience investments, regulatory oversight, and contingency planning rather than assuming market efficiency ensures reliability.

Pathway 2: Carbon Capture, Utilization, and Storage (CCUS) Deployment

Oil and gas companies possess distinctive competitive advantages for CCUS technologies:

• Geological Expertise: Decades of subsurface mapping, reservoir characterization, and sealing capability assessment
• Infrastructure Assets: Existing pipeline networks, compression facilities, and operational expertise
• Project Management: Established capabilities for managing complex capital projects across multiple jurisdictions
• Enhanced Oil Recovery: Experience with COâ‚‚ injection for viscosity reduction and production optimization

Norway’s Northern Lights Project: Commercial Validation

The Northern Lights facility represents the world’s first commercial cross-border COâ‚‚ transport and storage system:

• Ownership Structure: Equal partnership between Shell, Equinor, and TotalEnergies
• Operational Start: August 2025 (first commercial operations)
• Initial Feedstock: Captures 1.5 million tonnes COâ‚‚ annually from Heidelberg Materials’ Brevik cement plant
• Transport Infrastructure: COâ‚‚ transported via ship and 100-kilometer pipeline
• Storage Location: 2,600 meters beneath North Sea seabed with permanent geological sealing
• Phase 2 Expansion: €3.4 billion Norwegian Longship initiative and EU CEF funding backing; capacity expansion to 5 million tonnes annually by 2028

Hard-to-Abate Sector Applications:

• Cement Production: Northern Lights Phase 1 directly captures Brevik facility emissions
• Steel Manufacturing: CCUS applicability for blast furnace and electric arc furnace operations
• Chemical Production: Valuable for large-scale chemical synthesis where COâ‚‚ becomes raw material input
• Refining Operations: Integration potential for on-site refinery emissions capture and storage

Critical CCUS Limitations and Risks

Despite commercial validation, CCUS faces substantial challenges:

• Capture Efficiency Gaps: Current projects capture approximately 50% of COâ‚‚ versus the 95% required for meaningful net abatement
• Enhanced Oil Recovery Lock-in: Approximately 80% of existing CCUS projects utilize captured COâ‚‚ for Enhanced Oil Recovery, extending fossil fuel extraction rather than reducing cumulative emissions
• Environmental Risks: Potential COâ‚‚ leakage from geological storage reverses emission reductions; monitoring and remediation costs substantial
• Cost Competitiveness: High-CCUS transition pathway could cost $30 trillion more globally by 2050 compared to electrification and renewable alternatives
• Asian Expansion Concerns: Climate Analytics warns Asia’s CCUS plans could generate 25 billion tonnes extra greenhouse gases by 2050 through fossil fuel lock-in effects

Pathway 3: Hydrogen Production and Transition Technologies

Oil and gas companies maintain dominant positions in hydrogen production globally:

• Current Production Method: 95% of global hydrogen via Steam Methane Reforming (SMR) from natural gas
• Refinery Integration: Hydrogen essential for converting heavy petroleum fractions, desulfurization, and clean fuel production
• Historical Deployment: Extensive expertise in high-pressure hydrogen handling, compression, and pipeline transport

Blue Hydrogen and Decarbonization Applications

Steam Methane Reforming coupled with CCUS produces “blue hydrogen”:

• Carbon Intensity Reduction: Significantly lower than conventional grey hydrogen
• Oil Operations Applications: Hydrogen powering drilling equipment, heavy machinery, and production facilities to replace diesel consumption
• Viscosity Reduction: Hydrogen-based Enhanced Oil Recovery reducing viscosity more effectively than conventional EOR while decreasing emissions
• Steam Generation: Up to 76% of COâ‚‚ emissions during oil sands production eliminable using hydrogen for steam generation combined with CCUS

Green Hydrogen Potential

Electrolysis using renewable electricity offers zero-emission pathways:

• Technology Maturity: Green hydrogen production capability scaling rapidly
• Current Cost Premium: Higher than blue hydrogen but declining with electrolyzer cost reductions
• Industry Positioning: Oil and gas sector’s existing pipeline infrastructure, capital resources, and project management capabilities position it uniquely to scale hydrogen technologies
• Hard-to-Abate Sector Coverage: Hydrogen applications across heavy industry, aviation, shipping, and high-temperature processes

Technological Bottleneck Analysis: McKinsey estimates almost half of emissions reductions from present through 2050 could come from technologies currently in prototyping or demonstration stages, including CCUS and hydrogen applications. Oil and gas companies’ technical depth and infrastructure position them as critical enablers for this technological transition.

Corporate Strategy Divergence and Investor Pressure

Major oil companies exhibit sharply diverging strategic approaches to the clean energy transition:

BP’s “Reset” Strategy (February 2025)

• Renewable Energy Retreat: Cut renewable energy investment by over $5 billion annually
• Renewable Budget Level: Reduced to $1.5-2 billion yearly (down from $5+ billion)
• Oil and Gas Expansion: Increased spending 20% to $10 billion annually
• Production Target: Aiming for 2.3-2.5 million barrels oil equivalent per day by 2030
• Strategic Rationale: CEO Murray Auchincloss stated BP “went too far, too fast” in transition planning
• Market Drivers: Cited slower-than-expected renewable adoption and persistent hydrocarbon demand following Ukraine war disruptions
• Emissions Target Elimination: Replaced 35-40% Scope 3 emissions reduction target with 10% carbon intensity reduction
• Investor Pressure: Responding to activist shareholder demands for near-term profitability over long-term climate positioning

Shell’s “Dual-Track” Strategy

• Balanced Portfolio: Maintaining traditional hydrocarbon profitability while continuing low-carbon technology investments
• Investor Coalition Satisfaction: Simultaneously appeasing traditional energy investors and ESG-conscious stakeholders
• Strategic Flexibility: Preserving optionality as market signals and policy frameworks evolve
• Infrastructure Position: Leveraging integrated downstream capabilities and infrastructure assets

Sectoral Uncertainty: This divergence reflects broader industry uncertainty regarding transition timing, regulatory trajectory, carbon pricing implementation, and return on capital deployment. Companies face conflicting pressures from energy demand persistence, investor expectations, climate policy uncertainty, and capital cost dynamics favoring fossil fuels for near-term cashflow generation.

Conclusion

Oil’s importance for energy security rests fundamentally on its affordability, supply reliability across diversified sources, geopolitical significance through strategic reserve and transit route control, and industrial indispensability extending beyond energy uses to petrochemical feedstocks. The Sovereignty-Robustness-Resilience framework and Portfolio Theory inform strategic policies including India’s 40-country supplier diversification and Strategic Petroleum Reserve expansion. Geopolitical flashpoints—Middle Eastern conflicts, OPEC+ production decisions, sanctions regimes—continuously reshape supply security, while International Energy Agency projections under current policies show demand growing 13% to 113 million barrels per day by 2050 driven by petrochemical feedstock requirements, aviation fuel demand, and emerging economy growth across Asia and Africa.

In the clean energy transition, oil and gas industries contribute through multiple pathways: natural gas displacing coal and reducing emissions 50-70% per unit energy (though requiring robust infrastructure resilience), deploying CCUS in hard-to-abate sectors where Norway’s Northern Lights project demonstrates commercial viability at 5 million tonnes COâ‚‚ annually, and producing blue and green hydrogen for industrial decarbonization and renewable grid backup. However, formidable challenges persist: natural gas infrastructure vulnerability exemplified by the 2021 Texas crisis, CCUS’s limited capture efficiency and fossil fuel lock-in risks through Enhanced Oil Recovery applications, cost-competitiveness gaps versus renewable alternatives, and corporate strategy volatility as evidenced by BP’s retreat from renewables. Effective transition requires mandatory weatherization standards for natural gas infrastructure, selective CCUS deployment prioritizing genuine abatement over fossil fuel extension, accelerated green hydrogen scaling through electrolyzer cost reduction, carbon pricing mechanisms supporting coal-to-gas switching, and policy frameworks ensuring grid resilience during intermittent renewable integration. Oil’s dual role—securing present energy needs while enabling future decarbonization—demands sophisticated management balancing legacy infrastructure reliability with accelerated transition technology deployment.
