Australia Climate Tech Carbon Capture Market Size, Share, Growth and Forecast, 2025-2035

Safeguard limits and Moomba storage put CO2 storage to work

The Australia climate tech carbon capture market was valued at USD 159.5 million in 2025 and is projected to increase from USD 188.2 million in 2026 to USD 845.9 million by 2035, registering a CAGR of 18.18% during 2026–2035. Demand comes from gas processors, cement and lime makers, metals and chemicals plants, storage hub developers and public research programs that pay for CO2 separation, injection, engineering and new capture technology. Eastern States and ACT held the largest regional share, 77.3% in 2025, because the eastern seaboard hosts most of the population, manufacturing and research spending. Northern Territory is the fastest-growing region at 20.71% a year, as offshore storage sites near Darwin move toward development. Compliance rules are also tightening, because Safeguard Mechanism baselines generally decline by 4.9% each year. As a result, large emitters are turning to CO2 storage, mineral carbonation and low-cost solvents to cut emissions on site.

Which capture services, technologies and buyers does the estimate cover?

The estimate measures the value of geological CO2 storage operations, project development and engineering, capture technology sales and licensing, and research and demonstration work in Australia. Values are stated at the prices that energy operators, industrial emitters, hub developers and public research buyers pay for these services and technologies.

The estimate excludes forestry and soil carbon offsets, renewable power projects and general emissions consulting. The value chain runs from technology developers and engineering contractors through storage operators and regulators to gas processors, cement and lime plants, metals and chemicals makers and buyers of carbon removal.

Geological operations lead as removal grows fastest

Why do geological CCS operations lead service value?

Based on service type, the market is categorized into geological CCS operations, project development and engineering, capture technology commercialisation and research and demonstration. Geological CCS Operations led with a 58.0% share of 2025 value, because large gas projects already inject CO2 at scale. Capture Technology Commercialisation grows fastest at 19.33% a year, as new solvents, calciners and mineral carbonation plants move to commercial sales.

How do integrated energy operators dominate purchases?

Based on customer type, the market is categorized into integrated energy operators, independent industrial emitters, storage hub developers and public research buyers. Integrated Energy Operators led with 62.0% of 2025 value, because gas producers run the largest storage projects. Independent Industrial Emitters grow fastest at 19.20% a year, as cement, lime and chemicals plants face falling Safeguard baselines.

Why does natural gas processing lead end use?

Based on end-use industry, the market is categorized into natural gas processing, cement and lime, metals and chemicals, and atmospheric carbon removal. Natural Gas Processing led with 72.0% of 2025 value, because reservoir CO2 is separated during gas processing and can be injected nearby. Atmospheric Carbon Removal grows fastest at 19.95% a year, as storage developers sign up direct air partners.

How do captive systems and shared hubs split delivery?

Based on delivery model, the market is categorized into captive integrated systems, shared storage hubs, distributed capture installations and demonstration facilities. Captive Integrated Systems led with 60.0% of 2025 value, because Gorgon and Moomba store CO2 from their own gas plants. Shared Storage Hubs grow fastest at 19.15% a year, as developers plan storage for third-party emitters.

Safeguard baselines and new storage sites lift spending

How does industrial compliance tightening lift spending?

Industrial compliance tightening lifts spending on CO2 storage, because large facilities must cut emissions below a falling baseline each year. Safeguard baselines generally decline by 4.9% each year, according to the Clean Energy Regulator. Covered facilities numbered 207 in 2024-25 and reported 132.7 million metric tons of CO2 equivalent, down 2.4% from the year before. The Moomba project stored about 1 million metric tons in that period, or about one-third of the total Safeguard reduction, based on the regulator's data. As a result, independent industrial emitters grow fastest among buyers at 19.20% a year, as plants without their own storage look for capture partners.

Why does operating infrastructure expansion matter?

Operating infrastructure expansion matters, because working storage sites prove that CO2 can be injected safely and at a known cost. The Moomba facility can store up to 1.7 million metric tons of CO2 a year and started up in October 2024, according to Downer, which led its construction and commissioning. The project had stored about 2 million metric tons by May 2026, and more than 1.19 million carbon credit units were awarded for injections to Sept. 30, 2025. Chevron also reports more than 11 million metric tons injected at Gorgon from August 2019 to May 2025. In turn, geological CCS operations held 58.0% of 2025 value, as operators expand geological sequestration capacity.

How does public technology demonstration funding speed adoption?

Public technology demonstration funding speeds adoption, because grants cover part of the risk of first-of-a-kind plants. Calix won a US$10 million grant from the federal Carbon Capture Technologies Program in July 2024 for an electric calciner that targets up to 20,000 metric tons of CO2 a year from lime and cement. MCi Carbon received A$14.5 million from the same program in 2024 and A$14.6 million from a separate federal CCUS fund, according to Austrade. The federal government had also committed $60 million to the Gorgon injection project through an earlier demonstration fund. As a result, capture technology commercialisation grows fastest among service types at 19.33% a year.

Why do offshore storage approvals widen the project pipeline?

Offshore storage approvals widen the project pipeline, because declared formations let developers move toward investment decisions. INPEX Browse E&P received a declaration of an identified storage formation for the Bonaparte project in October 2026, according to Oil & Gas Journal. The project, about 260 km offshore Darwin, could store up to 10 million metric tons of CO2 a year, and INPEX holds 53%, TotalEnergies 26% and Woodside 21%. Pilot Energy also secured a declaration allowing 13.4 million metric tons of storage in the Cliff Head formation off Western Australia. In turn, hub developers and engineering contractors gain a larger pipeline of offshore storage work.

Shared hubs and mineral carbonation reshape the field

How is the shift toward shared storage hubs changing projects?

The shift toward shared storage hubs is changing project design, because emitters without suitable geology can send CO2 to a hub operator. Santos is positioning Moomba to take third-party emissions from sectors such as steel and cement, and its Cooper and Eromanga acreage could inject up to 20 million metric tons a year for up to 50 years. Ichthys LNG is expected to anchor Bonaparte and could cut its emissions by about 40%. Pilot Energy also expects injection capacity above 1 million metric tons a year at its Mid West project through 2050. As a result, shared storage hubs grow at 19.15% a year, faster than captive systems.

Why is the rise of mineral carbonation notable?

The rise of mineral carbonation is notable, because it turns captured CO2 into solid products that can be sold. MCi Carbon started production at its Myrtle plant in Newcastle in 2026, and it aims to capture 2,500 metric tons of CO2 a year from ammonia production. The plant is designed to make 10,000 metric tons of carbonates and silica a year and support up to 50 jobs at peak. RHI Magnesita invested US$10 million and will run the first customer campaign at Myrtle in 2026. In turn, Calix plans to sell up to 15,000 metric tons of CO2 a year for green methanol production.

Can low-cost solvents open demand among industrial emitters?

Low-cost solvents can open demand among industrial emitters, because cheaper capture lowers the cost of meeting Safeguard baselines. KC8 Capture Technologies, founded in 2021, raised $10 million in a round led by Woodside Energy and Cemex Ventures. The company says its non-toxic solvent can capture up to 95% of CO2 at a capital cost up to 50% below amine systems. It also claims up to 15% better energy efficiency, and it targets cement, steel, power and chemicals plants. As a result, cement and lime grow fastest among industrial uses at 19.95% a year, as plants test new capture options alongside fuel and process changes.

Is there room to grow through credit generation?

Credit generation leaves room to grow, because stored CO2 can earn tradeable units that improve project returns. Moomba earned more than 1.19 million carbon credit units for injections to Sept. 30, 2025, which shows how storage can produce revenue beyond service fees. About 7 million Safeguard credit units may be eligible for issue for 2024-25 from 59 facilities below their baselines. Australia also emitted about 383.4 million metric tons of CO2 in 2024, according to World Bank data, which leaves a large base for future abatement. In turn, operators that store CO2 can sell their units into the market for compliance offset units.

Cost, permits and long-term liability slow new projects

How do high upfront costs delay new capture projects?

High upfront costs remain a key barrier, because compression, pipelines, wells and monitoring need large investment before any CO2 is stored. Smaller industrial emitters feel this risk most, since their emissions are too small to justify their own storage site. As a result, many projects wait for grants or access to a shared hub. Developers respond with shared infrastructure, staged builds and modular capture units. Lower costs per metric ton should follow as hubs scale and more emitters connect.

Why do long permit timelines slow storage development?

Long permit timelines are a major constraint, because offshore storage needs acreage awards, formation declarations and safety approvals in sequence. Developers often face several years of assessment before injection can start at a new site. In turn, capital stays tied up and investors wait longer for any return. Regulators respond with clearer guidance and major project status for leading sites. Faster approvals would bring more storage capacity online before 2035.

How does long-term liability weigh on storage operators?

Long-term liability is a lasting risk, because CO2 must stay underground for centuries after injection ends. Operators must fund monitoring and remediation plans that last well beyond the life of each project. As a result, some investors demand higher returns or clear rules on liability transfer. Governments respond with closure and transfer provisions in storage laws. Clearer liability terms should attract more private capital to new storage projects.

Why does community skepticism complicate new projects?

Community skepticism is a growing challenge, because some groups see CO2 storage as a way to extend fossil fuel production. Developers near towns and coastlines face added consultation and closer scrutiny of monitoring plans. In turn, approvals and project financing can take longer than first planned. Operators respond with public monitoring data, independent reviews and local engagement programs. Transparent performance reports should build public trust in storage over time.

Eastern States lead while Northern Territory grows fastest

Why do the eastern States and ACT hold the largest share?

Eastern States and ACT held 77.3% of 2025 value and grow at 17.91% a year, because the region hosts most of the population, manufacturing plants, engineering firms and research programs. New South Wales, Victoria, Queensland, Tasmania and the ACT had about 22.6 million of Australia's 27.9 million residents at March 31, 2026. As a result, much of the engineering, technology and research spending is booked in the east. MCi Carbon's Myrtle plant in Newcastle adds mineral carbonation capacity in New South Wales.

How does Western Australia build on Gorgon and new sites?

Western Australia held 16.0% of 2025 value and grows at 19.01% a year, because Gorgon on Barrow Island has injected more than 11 million metric tons of CO2 since August 2019. Pilot Energy's declared Cliff Head formation adds 13.4 million metric tons of offshore storage in the Mid West. Calix's earlier lime work in Kwinana also links the state to cement and lime capture. In turn, the state has both operating and planned storage.

Why does South Australia matter through Moomba?

South Australia held 5.5% of 2025 value and grows at 18.76% a year, because the Moomba project in the Cooper Basin is the largest onshore storage site in the country. The project can store up to 1.7 million metric tons a year, and Santos and Beach Energy run it as joint venture partners. As a result, South Australia earns storage fees and credit units, while third-party capacity could add emitters from steel and cement.

How does the Northern Territory grow from a small base?

Northern Territory held 1.2% of 2025 value and grows fastest at 20.71% a year, because the Bonaparte project offshore Darwin received its storage formation declaration in October 2026. Pre-front-end engineering began in April 2025, and first injection is targeted for the early 2030s. In turn, engineering and development spending in the territory rises well before storage fees begin.

Moomba, Myrtle and Bonaparte marked 2024 to 2026

Solvents, calciners and mineralization widen options

• Reservoir CO2 separation and injection removes CO2 from natural gas during processing and injects it into deep sandstone formations, which suits large gas projects.
• Electric calcination heats limestone without mixing fuel gases with process CO2, which yields a pure stream for storage or use.
• Mineral carbonation reacts CO2 with minerals to form stable carbonates and silica, which creates products for building and industry.
• Next-generation solvents capture CO2 from flue gas with lower energy and capital cost, which suits cement, steel and chemicals plants.

Gas producers and builders lead as startups raise funds

Competition centers on storage access, engineering capability, technology cost and public funding. Santos operates the Moomba project with joint venture partner Beach Energy, and Downer led construction and commissioning of the facility. Chevron Australia runs CO2 injection at Gorgon on Barrow Island. INPEX Browse E&P operates the Bonaparte joint venture with TotalEnergies and Woodside Energy, which is also an investor in KC8 Capture Technologies. Pilot Energy holds a storage declaration for its Mid West project. Calix Limited and MCi Carbon lead in capture technology, backed by federal grants for calcination and mineral carbonation. Because geological operations hold the largest share of 2025 value, companies with storage rights hold the strongest position, while technology firms compete for industrial emitters.
