In short

Carbon capture timeline from 1972 CO2 injection and Sleipner to CCS hubs, direct air capture, offshore CO2 storage and Europe's largest 2026 capture plant.

Latest Story

Carbon capture sounds almost too neat: take the carbon dioxide from a factory, compress it, move it away, and lock it deep underground. After decades of experiments, engineers have shown that CO₂ can be captured and stored in geological formations. But in 2026, the hard question is no longer whether the technology can work. It is whether carbon capture can become large, cheap, safe and fast enough to matter in the climate fight. This carbon capture timeline follows the idea from 1972, when CO₂ was first injected into Texas oil fields, through Norway’s Sleipner project, the rise of direct air capture, shared CO₂ storage hubs, and Europe’s largest carbon-capture facility, which opened at Yara Sluiskil in the Netherlands in 2026.

Carbon Capture Timeline 1972–2026: CCS, Direct Air Capture & CO₂ Storage

Can We Bury Our Carbon Problem?

🧠 Quick Answer

Carbon capture is a set of technologies that capture CO₂ before or after it enters the atmosphere. CCS captures CO₂ from concentrated industrial sources and stores it underground. Direct air capture removes CO₂ already mixed into the air. Carbon capture can help reduce emissions from difficult industries, but it faces major challenges around cost, energy use, transport, storage capacity, monitoring and scale.

Carbon Capture: Key Questions

What is carbon capture?
Carbon capture refers to technologies that separate carbon dioxide from industrial exhaust or from ambient air, then use it or store it so it does not add to atmospheric warming. It covers point-source capture at factories and direct air capture from the open air.
What is the difference between CCS and DAC?
CCS captures CO₂ from a concentrated stream at a plant, where the gas is often 10 to 20 percent of the exhaust. Direct air capture pulls CO₂ from ambient air, where it is about 0.04 percent, so DAC needs far more energy per tonne. They are related but not interchangeable.
Where does captured CO₂ go?
Captured CO₂ is compressed into a dense fluid and injected into deep geological formations: depleted oil and gas fields or saline aquifers, usually more than a kilometre below land or seabed, under layers of impermeable cap rock, then monitored over time.
Can carbon capture slow climate change?
It can contribute, mainly for hard-to-abate industries such as cement, chemicals and fertiliser, but no single technology solves climate change. Its climate value depends on scale, cost, permanence, monitoring and whether it is used to cut genuinely difficult emissions rather than extend fossil-fuel use.
📚 Key Takeaways

What this carbon capture timeline really shows

  • Carbon capture is not one technology. CCS at a smokestack and direct air capture from ambient air solve different problems and carry very different energy and cost profiles.
  • Geological CO₂ storage has decades of track record at Sleipner, Weyburn and In Salah, but scaling it from tens of millions to billions of tonnes a year worldwide remains unproven.
  • CCS is most defensible for hard-to-decarbonise industries such as cement, chemicals, steel and fertiliser, where there is no easy switch to electricity.
  • Critics worry CCS becomes an excuse to keep burning fossil fuels, and point to slow deployment, high energy penalties and long-term monitoring duties.
  • The 2026 Netherlands project matters because it links industrial capture at Yara Sluiskil to cross-border offshore storage by Northern Lights, the first full chain of its kind in operation.
  • Carbon capture has to be judged on real numbers: annual tonnes captured, energy used, monitoring commitments and emissions actually avoided, not on announced capacity.

Where Does the CO₂ Go?

Carbon capture does not make emissions vanish. It changes the path of CO₂ from atmosphere to monitored storage.

🏭 The Same Factory, Two Different Paths
Choose what the plant does with its CO₂
Factory separates CO2 from its exhaust, compresses it into a dense fluid, moves it by pipeline or ship to an offshore site, and injects it into porous rock deep under the seabed, where it is monitored over time.
1 Factory burns fuel or runs a chemical process
2 CO₂ leaves the stack with the rest of the flue gas
3 Gas rises and mixes into the atmosphere
4 CO₂ stays in the air for centuries, adding to warming
1 Factory burns fuel or runs a chemical process
2 A solvent or membrane separates CO₂ from the exhaust
3 CO₂ is compressed into a dense fluid
4 Pipeline or ship carries it to an offshore storage site
5 It is injected into porous rock deep below the seabed
6 Sensors monitor the store for leaks over the years
⚠️ Illustrative. Real projects differ in capture rate, transport mode, storage geology and monitoring duration, and no site is called permanently safe without long-term measurement.

CCS and DAC Are Not the Same Thing

Related tools, different jobs — and the distinction matters for what each can honestly claim

CCS — Point-source capture
Source A concentrated stream at a plant: power station, refinery, cement kiln, steel mill, fertiliser plant, waste incinerator
Concentration CO2 is often 10 to 20 percent of the exhaust, sometimes much higher in gas processing
Effect Avoids emissions that would otherwise have gone up the stack
DAC — Direct air capture
Source Ambient outdoor air, anywhere
Concentration CO2 is about 0.04 percent of air, so far more air must be moved and far more energy used per tonne
Effect Can remove CO2 already in the atmosphere, including historical emissions
Why the wording matters: point-source capture avoids new emissions; direct air capture can remove CO₂ that is already up there. Calling every carbon-capture project “carbon removal” blurs that line, and it is one of the most common mistakes in coverage of the field.

The Industries CCS Is Really Aimed At

Sectors where switching to electricity is hard, because the CO₂ comes from chemistry or extreme heat, not just fuel choice

Hard to abate

Cement

Around half of cement’s CO₂ comes from the chemical reaction that turns limestone into clinker, not from the kiln fuel, so cleaner power alone does not fix it.

Hard to abate

Steel

Traditional blast furnaces use coke as both fuel and chemical reductant. Hydrogen routes exist but are early; CCS is one bridge for existing plants.

Hard to abate

Chemicals

Many processes need high-temperature heat and produce concentrated CO₂ streams as a by-product, which makes capture technically easier here than almost anywhere else.

Hard to abate

Fertiliser

Ammonia plants emit a nearly pure CO₂ stream during hydrogen production. Yara’s Sluiskil project captures exactly this stream.

Hard to abate

Waste-to-energy

Municipal waste incinerators burn a mix that is impossible to fully decarbonise at source, so capture is one of the few options for deep cuts.

Contested

Fossil power

CCS on coal and gas plants is where critics push back hardest, arguing the money and years are better spent on renewables, grids and storage.

Timeline: From Oilfield Injection to Cross-Border Storage, 1972–2030

Newest developments first. Where a project spans years, the entry marks the moment it changed the picture.

Carbon capture did not arrive as a single breakthrough. It grew out of oil-and-gas engineering, was picked up by climate policy, stumbled badly in the power sector, quietly proved itself in industry, and is now being rebuilt as shared infrastructure. Reading the sequence in order shows why the 2026 Yara Sluiskil opening is a milestone and not a beginning.

2030 ?

Can CCS Scale Enough to Matter?

Open question, through 2030Cost, permanence, regulation, public trust

What is at stake: Engineers can store CO₂. The unresolved question is whether it can be done at the scale climate models assume. Based on today’s project pipeline the IEA sees capture capacity reaching roughly 430 million tonnes a year by 2030 if everything announced is built, still a small share of global emissions and dependent on subsidies, permits and pipelines arriving on time.

Why it matters: The climate payoff depends less on the chemistry and more on price, permanence, regulation, public trust, and whether CCS is reserved for genuinely hard-to-abate emissions rather than used to prolong fossil-fuel demand.

~430 Mt/yr possible by 2030vs ~50 Mt/yr today

Yara Sluiskil Opens Europe’s Largest Carbon-Capture Facility

7 September 2026Sluiskil, Netherlands · Reuters

What happened: Fertiliser maker Yara inaugurated what Reuters described as Europe’s largest industrial carbon-capture facility at its ammonia plant in Sluiskil. From 2026 the plant will capture and liquefy up to 800,000 tonnes of CO₂ a year. The chain runs from ammonia production, to CO₂ capture and liquefaction, to ship transport, to storage about 2.6 km beneath the seabed on the Norwegian continental shelf by Northern Lights. Yara expects to remove roughly 12 million tonnes over 15 years.

Why it matters: This is the fresh trigger for revisiting the whole timeline. It is the first industrial-scale capture project wired into a cross-border commercial storage service, rather than a one-off site storing its own CO₂ next door. The prime ministers of Norway and the Netherlands and the EU climate commissioner attended, a signal of how central governments now consider this chain.

Interesting fact: the CO₂ from a Dutch fertiliser plant will be shipped to Norway and injected under the North Sea — a carbon supply chain that crosses two national borders before the gas is stored.
Up to 800,000 t CO₂/yr~12 Mt over 15 years

Northern Lights Stores Its First CO₂

August 2025Norwegian continental shelf

What happened: The Northern Lights joint venture, part of Norway’s state-backed Longship programme, received its first CO₂ by ship from a cement plant at Brevik and injected it into a reservoir about 2,600 m below the seabed. Phase one offers 1.5 million tonnes a year of storage, fully booked by Norwegian and European customers. A second phase, sanctioned in 2025, is designed to lift capacity above 5 million tonnes a year from 2028.

Why it matters: It created something new: a third-party CO₂ storage service that industrial emitters elsewhere in Europe can buy into, which is the piece the Yara chain plugs into a year later.

Phase 1: 1.5 Mt/yrPhase 2: 5+ Mt/yr from 2028

Porthos Begins Construction Under the North Sea

Construction from 2024Port of Rotterdam, Netherlands

What happened: Porthos, a joint venture of Dutch state energy firm EBN, gas network operator Gasunie and the Port of Rotterdam, started building a shared CO₂ pipeline and offshore injection system. It is designed to take about 2.5 million tonnes of CO₂ a year from Air Liquide, Air Products, ExxonMobil and Shell in the port and store it in depleted gas fields roughly 3 to 4 km beneath the North Sea, around 20 km offshore, for a total near 37 million tonnes over 15 years. Investment is put at about 1.3 billion euro.

Why it matters: Porthos is the clearest example of the shift from single-plant projects to shared hubs: one piece of infrastructure serving several factories at once, which is how CCS advocates argue costs finally come down.

~2.5 Mt CO₂/yr~37 Mt over 15 years

Big Subsidies Arrive, and India Publishes Its First CCUS Policy

2022United States · India

What happened: The US Inflation Reduction Act raised the 45Q tax credit to as much as 85 dollars per tonne for stored industrial CO₂ and 180 dollars per tonne for direct air capture, triggering a wave of announced projects along the Gulf Coast. In the same period NITI Aayog, India’s central policy think tank, released a Carbon Capture, Utilisation and Storage policy framework aimed at steel, cement, chemicals and refineries, sectors central to India’s 2070 net-zero target.

Why it matters: For years the barrier to CCS was not physics but economics. These moves tried to fix the incentive gap, and much of the current project pipeline dates from this shift.

45Q: up to $85/t storage$180/t for DAC
2020s

CCS Hubs and Shared CO₂ Networks Expand

Early-to-mid 2020sEurope, North America, Gulf

What happened: Planning shifted from isolated capture-and-store projects to clustered infrastructure: several factories in an industrial zone connected to a common CO₂ pipeline, shipping terminal and storage site. Rotterdam, the UK’s east coast, Norway and the US Gulf Coast all advanced versions of this model.

Why it matters: Shared transport and storage spreads fixed costs across many emitters and is the main route by which supporters expect CCS to move from demonstration to routine industrial service.

Direct Air Capture Becomes Commercial

May 2017Hinwil, Switzerland · Climeworks

What happened: Swiss company Climeworks opened what it billed as the first commercial direct air capture plant, pulling CO₂ from ambient air and selling it to a nearby greenhouse. Later plants in Iceland paired DAC with mineral storage underground.

Why it matters: DAC is a different category from CCS. It removes CO₂ that is already in the atmosphere rather than catching a concentrated industrial stream, but because outdoor air is only about 0.04 percent CO₂ it is far more energy-intensive per tonne, and remains small and expensive.

Interesting fact: capturing a tonne of CO₂ from a fertiliser plant’s near-pure stream and capturing a tonne from open air are so different in energy terms that treating them as the same technology is misleading.

The Paris Agreement Raises the Bar for Deep Decarbonisation

December 2015UNFCCC COP21

What happened: Nearly every country agreed to hold warming well below 2 degrees Celsius and to pursue 1.5 degrees. Most modelled pathways to those goals assume some carbon capture and some carbon removal, precisely because a few sectors are hard to electrify or clean up quickly.

Why it matters: Paris renewed institutional interest in CCS after a decade of disappointments, and framed it as a tool for the last, most stubborn slice of emissions rather than a licence for business as usual.

Boundary Dam: First Commercial CCS on a Coal Power Plant

October 2014Estevan, Saskatchewan, Canada

What happened: SaskPower retrofitted Unit 3 of its Boundary Dam coal station with post-combustion capture designed for roughly 1 million tonnes of CO₂ a year, most of it sold for enhanced oil recovery with some going to saline storage.

Why it matters: It proved capture could run on a working power plant, and it exposed the problem: high capital cost, an energy penalty that cuts plant output, and early reliability issues. Later power-sector CCS plans in the US and UK were cancelled or delayed on similar economics.

~1 Mt CO₂/yr designHigh cost and energy penalty
2000s –10s

Power-Sector CCS Stumbles, Industrial Storage Proves Itself

2000s into the 2010sUS, UK, Canada, Algeria

What happened: CCS was heavily promoted for coal and gas power because it promised lower emissions without shutting plants immediately. Many flagship power projects became too expensive or were abandoned. In parallel, industrial and gas-processing projects such as In Salah in Algeria and the Weyburn-Midale monitoring study in Canada showed that capture, transport and deep storage could work and could be measured for leaks.

Why it matters: This split still shapes the debate. The technology’s credible track record is in industry and gas processing, not in cleaning up power stations, which is where most public scepticism sits.

The IPCC Puts CCS on the Climate Map

2005IPCC Special Report on CCS

What happened: The Intergovernmental Panel on Climate Change published a dedicated special report assessing capture methods, pipeline safety, storage security and cost. It concluded that deep geological storage could retain the large majority of injected CO₂ over very long timescales if sites were well chosen and monitored.

Why it matters: It moved carbon capture from a petroleum-industry technique into mainstream climate policy language, and set the terms, evidence levels and cost models that governments still use.

Norway’s Sleipner Begins Storing CO₂ Under the North Sea

1996Sleipner field, Norwegian North Sea

What happened: Natural gas from the Sleipner field contained too much CO₂ to sell, so operator Statoil, now Equinor, separated it and, instead of venting it, injected roughly 1 million tonnes a year into the Utsira sandstone, a saline formation about 800 to 1,000 m below the seabed. Norway’s 1991 CO₂ tax made storage cheaper than paying to emit.

Why it matters: Sleipner is the first climate-relevant, dedicated offshore CO₂ storage project, and decades of seismic surveys tracking the CO₂ plume underground remain a core piece of evidence that geological storage can hold.

Interesting fact: a carbon price, not a technology breakthrough, is what turned Sleipner’s waste CO₂ into something worth burying.

CO₂ Injection Begins in Texas Oil Fields

1972Terrell County and the Permian Basin, Texas

What happened: Gas-processing plants in West Texas began separating CO₂ from natural gas and piping it to ageing oil fields, where it was injected to push out more crude, a practice called enhanced oil recovery. This was decades before climate policy treated buried carbon as a public issue.

Why it matters: Much of the CCS industry’s early engineering, from compression to pipelines to injection wells, comes straight from this oil-and-gas work. That heritage is also why critics are wary: the same tools can serve either climate storage or more oil production.

Supporters vs Critics

Carbon capture is promising, complicated and contested at the same time — both cases below are held by serious people

The case for CCS
Hard-to-abate industry Cement, steel, chemicals, fertiliser and waste have emissions rooted in chemistry and heat, not just fuel choice
Proven storage Sleipner, In Salah and Weyburn give decades of monitored injection data
Shared hubs Clustered pipelines and storage can bring per-tonne costs down
Model pathways Most routes to 1.5 to 2 degrees assume some capture and some removal
The case against relying on it
Cost and speed Projects are expensive and slow, and many announced ones never get built
Energy penalty Capturing CO2 uses energy, cutting a plant’s useful output
Lock-in risk CCS can be used to justify keeping fossil plants and fields running
Long-term duty Stores must be monitored and insured for a very long time

These are not mutually exclusive. A common middle position is that CCS is worth public money for genuinely hard-to-abate industry and for a limited amount of carbon removal, but is a poor substitute for cutting fossil-fuel use, building renewables and grids, improving efficiency and reducing methane.

Facts Worth Knowing

  • The first large-scale CO₂ capture was not for the climate at all — it was 1970s Texas gas processing, with the CO₂ used to squeeze more oil out of old fields.
  • Sleipner has been injecting about a million tonnes of CO₂ a year since 1996, and the plume has been tracked by repeated seismic surveys ever since.
  • Direct air capture and point-source CCS are often lumped together, but ambient air is roughly 0.04 percent CO₂, so DAC moves far more air and uses far more energy per tonne.
  • As of 2026 the world captures on the order of 50 million tonnes of CO₂ a year, against annual emissions in the tens of billions of tonnes.
  • The Yara Sluiskil to Northern Lights chain crosses two borders: a Dutch fertiliser plant’s CO₂ is shipped to Norway and stored under the North Sea.
  • No credible operator calls a storage site permanently safe without qualification — the standard is well-chosen geology plus long-term monitoring and clear liability.

People Also Ask

Is carbon capture the same as carbon offsetting?
No. Carbon offsetting is a financial arrangement where one party pays for emission reductions or removals elsewhere to compensate for its own emissions. Carbon capture is a physical process that separates CO₂ from exhaust or air. Some capture projects sell credits, but the technology and the accounting are separate things.
How deep underground is CO₂ stored?
Typically more than 800 m down and often well over a kilometre, deep enough that pressure and temperature keep CO₂ as a dense fluid. It is injected into porous rock capped by an impermeable layer. Sleipner stores at about 800 to 1,000 m below the seabed; Northern Lights injects near 2,600 m; Porthos targets 3 to 4 km.
What is the Yara Sluiskil carbon capture project?
It is a carbon-capture installation at Yara’s ammonia and fertiliser plant in Sluiskil, the Netherlands, inaugurated in September 2026 and described by Reuters as Europe’s largest. It captures and liquefies up to 800,000 tonnes of CO₂ a year, which is shipped to Norway for permanent storage under the seabed by Northern Lights.
What is Northern Lights CO₂ storage?
Northern Lights is a Norwegian CO₂ transport and storage service, part of the state-backed Longship programme, run as a joint venture involving Equinor, Shell and TotalEnergies. It receives liquefied CO₂ by ship and injects it about 2,600 m below the seabed. Phase one stores 1.5 million tonnes a year; a second phase targets more than 5 million tonnes a year from 2028.
Does carbon capture let companies keep polluting?
That is the core of the criticism. Point-source capture reduces a plant’s emissions but does not eliminate them, and building it can be used to justify keeping a fossil asset running for longer. Whether that is acceptable depends on the sector: many analysts support it for cement or fertiliser and oppose it as a way to extend coal power.

Frequently Asked Questions

What is carbon capture?
Carbon capture refers to technologies that capture carbon dioxide from industrial sources or directly from the air, then use it or store it so it does not enter the atmosphere. It is an umbrella term covering point-source capture at factories and power plants and direct air capture from ambient air.
What is CCS?
CCS stands for carbon capture and storage. It captures CO₂ from a concentrated source such as a refinery, cement plant, fertiliser plant, steel mill or power station, compresses it, transports it by pipeline or ship, and injects it into deep geological formations for long-term storage.
What is direct air capture?
Direct air capture, or DAC, uses chemical processes to pull CO₂ out of ordinary outdoor air. Because air contains only about 0.04 percent CO₂, DAC has to process very large volumes of air and needs a lot of energy per tonne captured, which makes it currently expensive and small-scale.
What is the difference between CCS and direct air capture?
CCS captures CO₂ from concentrated sources such as factories or power plants, where it can be 10 to 20 percent or more of the exhaust. Direct air capture removes CO₂ already dispersed in the open air at about 0.04 percent. DAC is usually far more energy-intensive because atmospheric CO₂ is so dilute.
Where is captured CO₂ stored?
Captured CO₂ is compressed and injected into deep geological formations such as depleted oil and gas fields or saline aquifers, usually more than a kilometre down, beneath layers of impermeable cap rock under land or seabed. It is then monitored to confirm it stays where it was put.
Can CO₂ be stored underground safely?
Decades of projects such as Sleipner and In Salah, plus the IPCC’s assessments, indicate that well-chosen sites can retain the large majority of injected CO₂ over very long timescales. Safety depends on site selection, injection management, monitoring and clear long-term liability, not on the technology alone.
Why is carbon capture controversial?
Supporters say it can cut emissions from industries that are hard to decarbonise. Critics question its cost, energy needs, slow deployment, long-term monitoring burden and its potential use as cover for continued fossil-fuel production. Both positions are held by credible experts.
Can carbon capture solve climate change?
No single technology can solve climate change. Carbon capture can be part of the toolkit, especially for hard-to-abate sectors, but it must work alongside renewable energy, electrification, efficiency, methane cuts and lower fossil-fuel use.
What happened in the Netherlands in 2026?
Reuters reported that Yara Sluiskil opened Europe’s largest carbon-capture facility in the Netherlands in September 2026, designed to capture and liquefy up to 800,000 metric tons of CO₂ per year for offshore storage by Northern Lights on the Norwegian continental shelf.
When did carbon capture technology begin?
Industrial CO₂ separation dates to 1972, when gas-processing plants in West Texas began removing CO₂ from natural gas and injecting it into oil fields for enhanced oil recovery. Climate-motivated storage began later, with Norway’s Sleipner project in 1996.
What is the Sleipner project?
Sleipner is a Norwegian North Sea gas field where operator Statoil, now Equinor, began separating CO₂ from produced gas and injecting about a million tonnes a year into the Utsira saline formation in 1996, prompted by Norway’s carbon tax. It is the first dedicated offshore CO₂ storage project.
What is enhanced oil recovery and how is it linked to CCS?
Enhanced oil recovery, or EOR, injects CO₂ into ageing oil reservoirs to push out more crude. It is where CO₂ capture, compression and pipeline engineering first scaled up in the 1970s. Critics note that CO₂-EOR can enable more oil production, so its net climate effect depends on accounting.
How much CO₂ does the world capture today?
As of 2026 the IEA tracks roughly 45 commercial capture facilities in operation with a combined capacity on the order of 50 million tonnes of CO₂ a year. That is small against global emissions of tens of billions of tonnes annually.
How much could carbon capture scale by 2030?
The IEA estimates that if all currently announced projects are built, global capture capacity could reach around 430 million tonnes of CO₂ a year by 2030. History suggests a significant share of announced projects will not be completed on schedule.
What is a CCS hub?
A CCS hub is shared infrastructure where several industrial emitters in one area connect to a common CO₂ pipeline, shipping terminal and storage site, instead of each building its own. Rotterdam’s Porthos and Norway’s Northern Lights are leading examples. The aim is to lower per-tonne cost.
What is Porthos?
Porthos is the first large Dutch CO₂ transport and storage project, based in the Port of Rotterdam. Under construction since 2024, it is designed to move about 2.5 million tonnes of CO₂ a year from port industries into depleted North Sea gas fields 3 to 4 km below the seabed.
Which industries is CCS most useful for?
Cement, steel, chemicals, fertiliser and waste-to-energy, where emissions come largely from chemical reactions or very high-temperature heat rather than fuel choice, so switching to electricity or hydrogen is slow or not yet viable at scale.
Why do critics oppose CCS on power plants specifically?
Because cleaner alternatives for electricity already exist. Critics argue that money and years spent retrofitting a coal or gas plant with capture would deliver more emission cuts if spent on wind, solar, grids and storage, and that power-sector CCS mainly extends fossil-plant lifetimes.
What is the energy penalty of carbon capture?
Capturing and compressing CO₂ consumes energy, so a plant fitted with capture produces less useful output, or burns more fuel, for the same result. The size of this penalty varies by process and is one reason capture adds cost.
Is captured CO₂ ever reused instead of stored?
Yes. Captured CO₂ can be used in beverages, greenhouses, building materials and synthetic fuels. Most utilisation is small-scale, and in many uses the CO₂ is released again later, so utilisation and permanent storage should not be treated as equivalent.
How is stored CO₂ monitored?
Operators use repeated seismic surveys, pressure and temperature sensors in wells, and surface and seabed measurements to track the CO₂ plume and check for leaks. Sleipner’s plume, for example, has been imaged by seismic surveys for more than two decades.
What happens if a storage site leaks?
A well-selected site under competent cap rock is expected to leak little or nothing, but regulation typically requires monitoring, a remediation plan and financial responsibility for decades after injection stops. Small, slow leaks would reduce the climate benefit rather than pose an immediate local hazard in most settings.
Does India use carbon capture?
India has pilot and study-stage activity rather than large operating plants. NITI Aayog published a CCUS policy framework in 2022 aimed at steel, cement, chemicals and refineries, sectors central to reaching net zero by 2070, and several public-sector firms have announced trials.
Is carbon capture the same as carbon dioxide removal?
Not exactly. Point-source capture avoids new emissions from a specific plant. Carbon dioxide removal, including direct air capture and some nature-based methods, takes CO₂ that is already in the atmosphere. The two serve different roles in climate strategy.
How much does carbon capture cost per tonne?
It varies widely by source. Capturing a near-pure CO₂ stream from a fertiliser or gas plant can cost tens of dollars per tonne, while dilute streams from cement or power cost more, and direct air capture costs are higher still. This is why subsidies such as the US 45Q credit are central to the economics.
Why did Norway build so much CO₂ storage?
Norway introduced a CO₂ tax in 1991, has extensive offshore geology and engineering from its oil industry, and has made CO₂ transport and storage a deliberate state-supported export business through the Longship programme and Northern Lights.
Can carbon capture be retrofitted to existing factories?
Sometimes, but it depends on space, the concentration and volume of the CO₂ stream, access to transport and storage, and the plant’s remaining life. Retrofits are common in gas processing and fertiliser, harder and costlier on older, dilute-stream power stations.
What is the Longship programme?
Longship, or Langskip, is Norway’s state-funded full-chain CCS project. It funds CO₂ capture at Norwegian industrial sites and the Northern Lights transport and storage infrastructure, which is designed to also take CO₂ from customers elsewhere in Europe.
Does carbon capture reduce air pollutants other than CO₂?
Capture plants often include additional gas cleaning, so some projects report cuts in sulphur dioxide, nitrogen oxides or particulates alongside CO₂. The primary purpose, though, is CO₂, and co-benefits vary by design.
Is carbon capture proven or experimental?
The individual steps, capture, compression, pipeline transport, injection and monitoring, are proven and have run for decades in industry and gas processing. What is still unproven is deploying them together, fast and cheaply, at the multi-billion-tonne global scale that climate targets imply.
