CCUS prevents emissions from leaving industrial assets; CDR extracts CO2 from ambient air. ~50 Mt CO2/yr capture capacity operating globally. ~430 Mt projected by 2030. ~60% of project pipeline at advanced stages (FEED or construction). Decarbonization ladder: low-cost operational wins, mid-cost structural shifts, high-cost residual solutions (CCUS/CDR). CCUS value chain: capture, compression/transport, geological storage, MRV/stewardship. CDR approaches: DACCS (direct air capture + storage), BECCS (bioenergy + CCS). Global market scaling but execution bottleneck: lacks bankable offtake, permitted transport/storage networks, repeatable hub models. Canada's carbon management strategy frames CCS as key for industrial decarbonization, clean fuels, hydrogen, and long-term competitiveness. TerraNova platform provides dynamic MACCs, policy-aware abatement economics, and residual emissions strategy. By Koorosh Behrang, Climate Decode. | 1 | ## Two Different Tools for Two Different Problems | | --- | --- | Carbon capture and carbon removal are frequently conflated — but they address fundamentally different stages of the emissions problem. Understanding the distinction matters for strategy, project economics, and long-term planning. | ### Carbon Capture (CCUS) Preventing emissions from leaving the asset Separates CO₂ from a concentrated stream at a facility — before release — then moves it for permanent storage or use. • Combustion sources: boilers, furnaces, gas power • High-purity CO₂ streams: natural gas processing • Industrial point sources: cement, steel, chemicals • Deep-decarbonization lever for operating assets | ### Carbon Removal (CDR) Balancing what you cannot eliminate Extracts CO₂ from the atmosphere — directly or indirectly — and stores it durably. Not about cleaning up a smokestack; about balancing residual emissions. • DACCS: Direct Air Capture + Storage • BECCS: Bioenergy + CCS (net removals) • Market pricing durability as premium • Verifiability and permanence are key | | --- | --- | | 2 | ## How They Work — Without the Textbook | | --- | --- | ### The Capture Value Chain (CCUS) Separate CO₂ → condition it → move it → store it permanently (or use it in a way that doesn't re-emit it). | Capture Solvents, membranes, sorbents | Compression & Transport Pipeline or ship at scale | Geological Storage Deep formations, permanent | MRV & Stewardship Monitoring, verification | | --- | --- | --- | --- | Capture draws on solvents, membranes, sorbents, cryogenic separation, or process-integrated approaches (sector-dependent). At scale, compression and transport move via pipeline or ship. Geological storage is placed in deep formations with monitoring, verification, and long-term stewardship. ### The Removal Loop (CDR) Pull CO₂ from air → prove you did it → store it durably. Key Insight Removal is less about the separation chemistry (which is hard) and more about building a credible system around energy supply, permanence, MRV, contracting, and storage governance. The technology is only one piece of the investment case. | 3 | ## Why These Technologies Show Up Late in Real Decarbonization Roadmaps | | --- | --- | There is a practical sequencing that most executives recognize when they see it on one page. Capture and removal are not "Plan A" because they are typically capex-heavy, infrastructure-dependent, and require strong MRV and permitting certainty. | 1 | Low-Cost Wins Operational efficiency & waste elimination Energy efficiency, waste heat recovery, maintenance & controls tightening, electrify what's already electric-ready. | | --- | --- | | 2 | Mid-Cost Structural Shifts Electrification, fuel switching, process improvements Electrification where feasible, fuel switching, process redesign where economics allow. | | --- | --- | | 3 | High-Cost Residual Solutions Capture, removals, or full process redesign Carbon capture at the asset, CDR (DACCS/BECCS) for residual balancing, full process redesign when cheaper options are exhausted. | | --- | --- | When CCUS & CDR Become Plan A When cheaper levers no longer move the needle enough, the asset must still operate, and the organization is serious about meeting absolute targets — these are no longer optional additions to the roadmap. | 4 | ## Global CCUS in 2025: Scaling Is Real, Execution Is the Bottleneck | | --- | --- | The IEA's latest update shows a market moving beyond "announcements" into maturation — but still not at the pace implied by net-zero pathways. | ~50 Mt CO₂/yr capacity operating as of Q1 2025 IEA • April 2025 | ~430 Mt Achievable by 2030 if trajectories hold IEA • April 2025 | ~80% Near-term capacity in North America or Europe IEA • April 2025 | | --- | --- | --- | The pipeline is more credible than in prior cycles — roughly 60% of overall project volume now sits at advanced stages (FEED or under construction). The world is not short of CCUS concepts. What it lacks: • Bankable offtake and revenue certainty • Permitted transport and storage networks • Repeatable project delivery models (hubs) • Capital discipline that survives commodity and policy cycles Strategic Implication The infrastructure story — transport and storage hubs — matters as much as capture equipment. Project economics and project access are inseparable. | 5 | ## A Canada Lens: Storage, Infrastructure, and Investability | | --- | --- | Canada's national strategy frames carbon capture and storage as part of the solution set for industrial decarbonization, clean fuels and hydrogen, long-term competitiveness in emissions-intensive sectors, and enabling durable pathways where electrification is constrained. But the strategic message underneath is more important: capture and storage only scale when the **full system is investable** — technology, infrastructure, MRV, and policy alignment working together. No single element closes the investment case alone. | 6 | ## Turning "CCUS Ambition" into a Financeable Pathway | | --- | --- | Most corporate plans treat CCUS and CDR like static line items: "CCUS in 2032," "removals in 2040," "assume cost down." That approach breaks when the organization hits three hard questions: • When do we stop chasing incremental efficiency and commit to deep decarbonization capex? • Under what carbon price, incentive, and energy-price conditions does CCUS cross the investment hurdle? • What is the least-cost pathway to address residual emissions — capture, removals, or process redesign — and when? TerraNova's role is to answer these with decision-grade economics, not slogans. |   ### Dynamic MACCs Abatement curves that evolve as cheaper options saturate, energy prices change, carbon prices tighten, incentives step down, and timelines shift. |   ### Policy-Aware Economics Incentive stacks (tax credits, ITCs, grants, CfDs), compliance value (ETS/OBPS/TIER/CFR), and delivery risk modelled into NPV/IRR outputs. |   ### Removals Strategy Removals strategy explicit about durability and MRV, aligned with residual emissions forecasts, integrated into long-term cost curves. | | --- | --- | --- | The Output A decarbonization roadmap that doesn't just say "CCUS is important" — but shows when it becomes rational, what makes it investable, and how it competes against alternatives across time.
