Aligning Carbon Capture Technologies with 2035 SDG Targets for Industrial Decarbonization
Aligning Carbon Capture Technologies with 2035 SDG Targets for Industrial Decarbonization
The Carbon Capture Imperative: A Race Against Time
The industrial sector stands as a behemoth of greenhouse gas emissions, accounting for approximately 24% of global CO₂ emissions according to the International Energy Agency (IEA). As the clock ticks toward 2035—the deadline for achieving critical Sustainable Development Goals (SDGs)—carbon capture technologies emerge as both a lifeline and a paradox. They promise salvation through decarbonization yet demand ruthless efficiency to scale in time.
The 2035 SDG Crucible
SDG 13 (Climate Action) and SDG 9 (Industry, Innovation, and Infrastructure) set unambiguous targets: by 2035, industries must slash emissions by at least 45% from 2010 levels to limit warming to 1.5°C. This mandate leaves no room for incrementalism—only radical technological adoption will suffice.
Carbon Capture Archetypes: A Technical Taxonomy
Three principal carbon capture methodologies dominate industrial applications, each with distinct advantages and scalability challenges:
- Post-Combustion Capture: Chemical solvents (e.g., amine scrubbing) extract CO₂ from flue gases. Current efficiency: 85-90% capture rate at 40-60 kWh/ton CO₂.
- Pre-Combustion Capture: Gasification converts fuels to hydrogen and CO₂ before combustion. Achieves 95% purity but requires complete plant retrofits.
- Oxy-Fuel Combustion: Burns fuels in pure oxygen, yielding concentrated CO₂ streams. Energy penalty: 20-25% of total output.
The Scalability Equation
Projections from the Global CCS Institute reveal a chilling gap: current global capture capacity sits at 40 million tons annually, while 2035 targets demand 1.7 billion tons for industry alone. Bridging this chasm requires:
- CAPEX reduction from $60-80/ton to under $30/ton
- Energy penalties below 15% across all methods
- Integration with renewable energy microgrids
Sector-Specific Decarbonization Protocols
Cement Production: The Calcination Conundrum
Process emissions constitute 60% of cement's carbon footprint—unavoidable by conventional means. Emerging solutions include:
- Electrified kilns coupled with calcium looping (pilot phase, 70% capture demonstrated)
- Solidia Cement chemistry reducing process emissions by 30% intrinsically
Steel Manufacturing: The Hydrogen Horizon
Blast furnaces emit 1.8 tons CO₂ per ton of steel. Transition pathways demand:

The Policy-Market-Technology Trilemma
Regulatory frameworks must evolve at quantum speed to match technological progress:
- Carbon Border Adjustments: EU CBAM mandates reporting from 2026, full implementation by 2034
- 45Q Tax Credits: US incentives of $85/ton for geologic storage, $60/ton for utilization
- ISO Standardization: ISO 27914:2017 for storage monitoring requires expansion to industrial integration
The Storage Labyrinth
Geologic storage capacity theoretically exceeds needs (10,000+ Gt globally), but siting constraints create bottlenecks:
- Saline aquifers require 50-100 km proximity to emission sources for economic viability
- Enhanced Oil Recovery (EOR) accounts for 73% of current utilization but conflicts with SDG mandates
Innovation Frontlines: Breakthrough Technologies on the Horizon
Direct Air Capture (DAC) Industrial Symbiosis
Modular DAC units co-located with factories could offset residual emissions. Current leaders:
- Climeworks Orca: 4,000 tons/year capacity at $600/ton (projected $200/ton by 2030)
- Carbon Engineering: Liquid DAC achieves 90% capture at pilot scale
Biological-Industrial Hybrid Systems
Genetically engineered cyanobacteria strains now demonstrate:
- CO₂ fixation rates of 20g/m²/day in photobioreactors (5x natural photosynthesis)
- Direct conversion to ethylene and isobutanol at laboratory scale
The Hard Truths: Non-Negotiable Requirements for 2035 Alignment
- Temporal Certainty: Final investment decisions for large-scale projects must occur before 2027 to meet 2035 targets
- Material Throughput: Sorbent production must scale from kilotons to megatons annually (e.g., MOFs, zeolites)
- Grid Symbiosis: Carbon capture must integrate with renewable power curves, requiring 2-4x overbuild of clean energy capacity
The Cost of Failure
IPCC AR6 projections show the industrial sector consuming 35% of the remaining carbon budget by 2035 under business-as-usual scenarios. This would trigger:
- Lock-in of 650+ Gt CO₂ from new industrial infrastructure
- Violation of SDG 13.2 (integration into national policies)
- Physical climate risks to 78% of industrial assets located in vulnerable zones
The Path Forward: A Technical Manifesto
- Phase-out Thresholds: Ban new unabated industrial facilities from 2026 onward (EU draft directive COM/2023/230)
- CO₂ Takeoff Agreements: Mandate off-take contracts for captured carbon equivalent to 20% of emissions by 2030
- Material Passports: Digital twins tracking embedded carbon across industrial supply chains (Blockchain-enabled)
The Final Calculation
The arithmetic is unforgiving: deploying carbon capture at necessary scale requires installing one industrial-scale unit every 36 hours between now and 2035. This demands:
- $1.2 trillion cumulative investment (IEA Net Zero Scenario)
- Workforce training for 2.5 million new technicians globally
- Standardization across 140+ industrial process types
