Shell Scenarios: US Net-Zero CO₂ Energy System by 2050

Overview

Shell outlines a pathway for achieving a net-zero carbon dioxide energy system in the US by 2050. This transformation requires:

• Deep electrification with renewable sources (85% of electricity by 2050)
• Deployment of low-carbon fuels (hydrogen, biofuels)
• Carbon capture, utilization, and storage (CCUS)
• Policy frameworks and sectoral coalitions

Key Actions Required

Accelerate Clean Technologies

• Electrify economy with renewable energy
• Commercialize hydrogen (reaching 7% of energy consumption by 2050)
• Expand bioenergy use with sustainable feedstocks
• Increase electrification across sectors (buildings, transport, industry)

Support Energy-Efficient Choices

• Improve energy productivity (45% reduction in primary energy intensity by 2050)
• Upgrade infrastructure (electric vehicle networks, smart grids)
• Implement national efficiency standards

Remove Carbon Emissions

• Deploy CCUS at scale (300 MtCO₂/year by 2050)
• Utilize bioenergy with carbon capture and storage (BECCS)
• Create negative emissions through sustainable practices

Policy Recommendations

• Carbon pricing trajectory ($35/tCO₂ in 2030 to $140/tCO₂ in 2050)
• Comprehensive policy frameworks (sectoral mandates, standardization)
• Nature-based solutions (afforestation, soil carbon enhancement)
• Industrial strategy and innovation policy support

Societal Transformations

• Job market shifts (900k clean energy jobs created 2009-2015)
• Regional economic realignment (energy-producing regions diversification)
• Environmental justice principles ensuring equitable transition benefits

Implementation Approach

• Sectoral coalitions enabling collaborative decarbonization
• Just transition pathways managing disruptions
• Phased approach balancing urgency with innovation timelines

This pathway requires unprecedented cooperation across government, industry, and society by 2050 to achieve net-zero emissions, leveraging US innovation strengths while managing economic and social impacts.
