Can carbon capture technology become the primary tool for emissions reduction through large-scale deployment in the future?

• Amine-based solvent absorption is relatively inexpensive among carbon capture technologies, costing only $40–80 per ton of CO₂ captured from flue gas (with CO₂ volume concentration of 15–30%). Its full-cycle cost in Europe is approximately $120–180 per ton—including energy requirements. However, since European carbon trading prices remain below this full-cycle cost, dedicated projects remain limited. • Spreading silicate rock powder across fields can absorb some CO₂—a technique already used in soil improvement, with abundant rock powder supplied by mines. Even deployed at geoengineering scale, however, this method could absorb only several billion tons of CO₂ annually—insufficient to meet needs. Logistics costs must also be factored in. Does ocean iron fertilization in the Southern Ocean to induce carbon sequestration, mass deployment of ultra-high-temperature nuclear reactors to decompose atmospheric CO₂, or using sodium-powder-containing fuels to generate sodium carbonate aerosols and alkaline rain over oceans count as broad-sense carbon capture technologies? • Of course, each carries distinct risks: marine photosynthetic organisms may respond unpredictably; scaling up nuclear fission to process CO₂ would generate vast quantities of fissile material—tempting nations undertaking such projects to mass-produce thermonuclear warheads; sodium carbonate aerosols pose serious health hazards to humans and may disrupt ecosystems even during remote-ocean operations. Yet compared to the damages of continued warming, these risks might be deemed acceptable—so we shall see how long humanity chooses to wait. Among all carbon capture technologies, Bioenergy with Carbon Capture and Storage (BECCS)—which combines carbon capture with storage—was labeled “an outright disaster” in a report published on April 13, 2026, in *New Scientist* (by Michael Le Page).

5.5 Why This Phase Represents the Window of Greatest Investment Divergence Source of Divergence Optimistic Logic Pessimistic Logic Key Triggers to Monitor Green Hydrogen Cost Declining renewable electricity prices and electrolyzer costs, plus economies of scale. Low utilization hours, expensive storage and transport, and lack of premium pricing downstream. Long-term procurement contracts, direct green-power supply, and continuous load operation. Hydrogen-based Ironmaking Premium demand for green steel and trade regulations creating market incentives. High capital expenditure for high-grade ore, hydrogen supply infrastructure, and new processes. Capacity utilization rates and per-ton steel production costs of first commercial plants. CCUS for Cement Process emissions are unavoidable; policy will ultimately require payment. High energy penalty for capture; unclear responsibilities for pipeline networks and geological storage. Standardized methodologies, carbon pricing, public pipeline infrastructure, and long-term liability frameworks. Low-Carbon Fuels Hard-to-abate demand in aviation and shipping creates sustained markets. Feedstock competition, conversion losses, and complex certification standards. Mandatory blending mandates, fuel standards, and maritime carbon pricing. Retrofitting Existing Buildings Multiple benefits: energy savings, improved comfort, and equipment upgrades. Fragmented projects, long payback periods, and high financing costs. Bulk procurement for public buildings, energy-savings performance guarantees, and subsidies. Phase Assessment: Winners in Phase Two are often not those with the most radical technological narratives—but rather integrators capable of bundling infrastructure, raw materials, equipment, certification, and long-term procurement into bankable projects. Chapter 6 Third Phase (Approx. 2046–2060): Net-Zero Completion — Residual Emissions and Removal When mature mitigation measures are largely exhausted, each remaining ton of emissions becomes more expensive, harder to quantify, and increasingly dependent on long-term accountability systems. 6.1 What Remains by 2060? The net-zero completion phase will not confront today’s average emissions—but rather those residual emissions that persist after multiple rounds of screening and prove economically infeasible to eliminate. Typical sources include process emissions from cement and lime production, long-haul aviation and deep-sea shipping, certain high-temperature industrial processes, agricultural methane and nitrous oxide, and emergency grid backup power under extreme scenarios. This book adopts a working range of 1.5–2.5 billion tons of CO₂e for residual emissions in 2060—and requires an equivalent, verifiable, and sustainable removal capacity. This is not an official target but a stress test set for infrastructure planning and investment analysis. If mitigation in the first two phases falls short of expectations, residual emissions will rise, and removal demand and associated costs will increase non-linearly; conversely, faster-than-expected technological progress could reduce required removal volumes. 6.2 Removal Portfolio: Ecological Carbon Sinks and Engineered Removal Are Not Interchangeable Removal Method Advantages Constraints Key Investment & Research Priorities Forests, Grasslands, Wetlands Relatively low cost; delivers co-benefits for ecosystem health. Vulnerable to fire, pests/diseases, land-use competition, saturation, and reversibility. Long-term monitoring, insurance mechanisms, secure land tenure, and ecological quality—not just area—metrics. Soil and Agricultural Carbon Sequestration Synergistic with agricultural productivity enhancement. Highly dispersed, measurement uncertainty, sustainability contingent on ongoing management. Low-cost monitoring, farmer incentives, regional baselines. BECCS Leverages biomass to absorb CO₂ and permanently sequester it—enabling net-negative emissions. Sustainability of biomass feedstocks, land/water use, transportation, and storage logistics. Sustainable feedstock sourcing, combined heat-and-power integration, CO₂ transport and storage networks. Direct Air Capture with Carbon Storage (DACCS) Flexible siting; theoretically high durability. High energy demand, high cost, limited experience with large-scale deployment. Integration with low-carbon energy, advanced sorbent materials, modular design, and long-term removal procurement mechanisms. Mineralization and Durable Materials Long-term stability; potential synergy with industrial waste streams. Reaction kinetics, raw material logistics, and boundary definition for accounting. Mineralized construction materials, industrial waste treatment, product standards.
