Decarbonization ladder: low-cost operational efficiency ($0-30/tCO2e), mid-cost fuel switching/electrification ($30-100/tCO2e), high-cost CCUS/hydrogen/process redesign ($80-200+/tCO2e). Cement capture costs ~US$88-161/t. Storage costs single-digit to low tens $/t in favorable basins. U.S. 45Q: $85/t geologic storage, $60/t utilization, $180/t DAC (output-based per-tonne credit). Canada CCUS ITC: 60% DAC capture, 50% other capture, 37.5% transport/storage (capex-based refundable credit to 2030, then step-down to 2040). 45Q improves operating economics (performance-linked); Canada ITC de-risks deployment via upfront capital reduction (investment-linked). TerraNova: dynamic MACCs, policy-aware abatement value, scenario stress testing, NPV/IRR/payback. By Koorosh Behrang, Climate Decode. | 1 | ## The Decarbonization Ladder: From Low-Hanging Fruit to CCUS | | --- | --- | Industrial decarbonization rarely follows a single "silver bullet" pathway. In practice, most facilities move through a sequenced abatement curve: first capturing low-cost operational gains, then pursuing deeper — but increasingly expensive — technology shifts. CCUS becomes most relevant after the "cheap wins" have been largely harvested. | Low-Cost Levers $0–$30/tCO₂e | Energy efficiency (motors/VFDs, heat recovery, controls optimization), maintenance, steam trap programs, compressed air management, operational setpoint optimization. | | --- | --- | | Mid-Cost Levers $30–$100/tCO₂e | Fuel switching (coal to gas, gas to electrified heat), onsite renewable power/PPAs, material substitution and process tweaks. | | --- | --- | | High-Cost Levers $80–$200+/tCO₂e | Full process redesign, new furnaces/chemistries, hydrogen, e-fuels, high-temperature electrification, **CCUS** (point-source capture), and carbon removal. | | --- | --- | This ladder is exactly why strategy needs to be dynamic: the marginal cost of the next tonne abated rises as options are exhausted, and the optimal mix varies by site, sector, grid, and policy regime. | 2 | ## CCUS Is Expensive — So Cost Per Tonne Matters | | --- | --- | The central investment question is not whether CCUS "works" technically, but what it costs per tonne abated — inclusive of capture, compression, transport, storage, and monitoring — then netted against policy value. Representative Cost Signals • **Cement capture** (post-combustion, CO₂ avoided basis): ~US$88–$161 per tonne depending on plant scale and context • **Industrial capture costs** vary widely by sector, CO₂ concentration/pressure, capture fraction, and energy prices • **Storage costs** can be single-digit to low tens of dollars per tonne in favorable onshore basins, but rise in less favorable or offshore contexts Implication Once a facility has captured efficiency gains and feasible fuel switching, the remaining abatement often sits in the high-cost tail. That is exactly where CCUS becomes an "inevitable" pathway — *but only* if policy and markets close the gap between abatement cost and abatement value. | 3 | ## Why Policy Support Is Not Optional for CCUS | | --- | --- | Because the cost is high and the asset life is long, CCUS investment typically requires a stack of policy support: | ### Carbon Price / Compliance Value ETS, OBPS/TIER-type systems, LCFS/CFR-type systems where applicable. | ### Tax Incentives To lower capex and/or create per-tonne revenue for captured and stored emissions. | ### Infrastructure Enablement Transport + storage hubs and permitting certainty for long-lived projects. | | --- | --- | --- | | 4 | ## Incentive Design: Output-Based (45Q) vs Capex-Based (Canada CCUS ITC) | | --- | --- | ### United States — Section 45Q (Per-Tonne Credit) 45Q is structured as a production/output credit: value accrues in proportion to verified tonnes captured and securely stored or utilized. It embeds strong labor standards as a gateway to the highest credit values and includes minimum capture thresholds that differ by facility type. | $85/t Geologic storage (point-source) | $60/t Utilization / EOR (typical) | $180/t Direct air capture (storage) | | --- | --- | --- | ### Canada — CCUS Investment Tax Credit (Refundable % of Capex) Canada's CCUS ITC is primarily a refundable investment credit applied to eligible expenditures, with rates differentiated by capture type and a time-based step-down. | Eligible Expenditure Type | 2022–2030 | 2031–2040 | | --- | --- | --- | | Capture (directly from ambient air) | 60% | 30% | | Capture (other than ambient air) | 50% | 25% | | Transport / storage / use | 37.5% | 18.75% | Design Distinction That Matters | **45Q** improves project economics through ongoing per-tonne revenue (performance-linked). | **Canada's ITC** de-risks deployment by reducing upfront capital intensity (investment-linked). | | --- | --- | In practice, the "better" policy depends on what's binding for the project: the financing hurdle (capex shock) or the operating economics (per-tonne net cost). | 5 | ## Where TerraNova Fits: Making CCUS Investable | | --- | --- | Most organizations still evaluate decarbonization options using static MACCs — single-year costs, average assumptions, limited policy integration. That approach routinely mis-prices CCUS because it fails to treat incentives and carbon markets as dynamic financial variables. | Dynamic MACCs Facility and pathway specific — shows how marginal abatement cost evolves as cheaper levers saturate. | Policy-Aware Abatement Value Models incentive stacks explicitly (tax credits + carbon pricing + compliance exposure), turning "$/t cost" into net abatement economics. | | --- | --- | | Scenario Stress Testing Carbon price trajectories, incentive step-downs, energy price cases, capture rate sensitivity, and timing. | Finance-Grade Outputs NPV/IRR/payback by lever, portfolio constraints (capex limits, downtime windows), and sequencing logic. | ## Bottom Line CCUS is not a first resort. It is a late-stage, high-capex, high-impact lever that becomes strategically unavoidable in many industrial pathways once low-cost levers are exhausted. But for CCUS to scale, economics must be engineered through credible policy design — and that means translating incentives like **45Q** and **Canada's CCUS ITC** into bankable, scenario-tested investment cases.
