You’ve probably heard the debates. Carbon capture is too expensive. It’s a fantasy. It’s just a way for oil companies to look green. But when you cut through the noise and look at the actual steel in the ground, a different picture emerges. The short answer to your question is a definitive yes. There are successful carbon capture projects operating right now, pulling millions of tons of CO2 out of the industrial process or even straight from the air. They’re not just pilot plants or PowerPoint slides; they’re full-scale, commercial operations with years of runtime. This article isn’t about theoretical potential. It’s a field report on what’s actually working, why it works, and what these pioneers teach us about scaling this technology up.

Why does this question matter so much? Because if we’re serious about hitting net-zero targets, we need every tool in the box. Renewables and efficiency are the bedrock, but they can’t decarbonize everything overnight. Heavy industries like cement, steel, and chemicals have process emissions that are incredibly hard to eliminate. Carbon capture and storage (CCS) and its newer sibling, direct air capture (DAC), are the leading candidates to tackle these stubborn emissions. Knowing what success looks like today is the first step to building more of it tomorrow.

Five Carbon Capture Projects That Moved Beyond the Lab

Let’s get concrete. Success here means a project that is operating at a significant scale, has been running for a meaningful period, and is verifiably capturing and storing or utilizing CO2. It’s not about being perfect or profit-making without any support. It’s about proving the technological and operational concept in the messy real world. The following table breaks down five projects that meet this bar.

Looking at that table, a few things jump out. The scale is real—these are million-tonne operations, not small demos. They use different technologies for different emission sources. And their “business models” vary wildly, from selling CO2 for oil recovery to relying on government funding and carbon credits.

Boundary Dam: The Trailblazer That Proved It Could Be Done

When SaskPower launched the Boundary Dam 3 project in 2014, it was a genuine moonshot. No one had retrofitted a commercial coal plant with full-scale carbon capture before. The project had its share of headaches—early technical issues, cost overruns, and downtime. Critics pounced. But here’s the non-consensus view: those struggles were the success.

Boundary Dam proved that post-combustion amine scrubbing, a technology used in other industries for decades, could work on the variable, dirty flue gas of a power plant. It forced engineers to solve real-world problems like solvent degradation and waste management. More importantly, it created an entire local supply chain and a workforce with hands-on CCS experience.

Its financial key was linking the captured CO2 to Enhanced Oil Recovery (EOR) operations at the nearby Weyburn oilfield. This created a buyer (Cenovus) and a revenue stream. While controversial (it produces more oil), this model made the project financially viable and provided a clear, regulated pathway for the CO2. Without that offtake agreement, the project likely wouldn’t have happened. It shows that for early projects, finding a commercial use for CO2 isn’t a bonus—it’s a necessity.

Quest: A Different Blueprint for Success

While Boundary Dam grabbed headlines, Shell’s Quest project, starting a year later, quietly became one of the most reliable operations in the world. Its approach was different. Instead of a coal plant, it captures CO2 from a hydrogen manufacturing unit at the Scotford Upgrader, which processes oil sands bitumen.

The process here is "pre-combustion" capture. It’s inherently more efficient because the CO2 stream is more concentrated and at higher pressure after the “sour gas shift” reaction. This gave Quest a head start on efficiency. But its real masterstroke was the decision to not use EOR.

Quest injects its CO2 into a deep saline aquifer over two kilometers underground. This is pure storage, with no commercial product. How is that successful? Because it was designed from the start as a publicly-supported demonstration. Funding from the governments of Canada and Alberta covered a large portion of the capital cost. The goal wasn’t immediate profit; it was to prove the entire chain—capture, pipeline transport, and secure saline aquifer storage—at scale and drive down costs for future projects. By 2021, Shell reported it had reduced operating costs by 30% from the original design. Quest proved that dedicated geological storage is a viable, safe option, which is crucial for projects not located near oilfields.

The New Wave: Direct Air Capture Steps Up

Projects like Orca by Climeworks represent a different beast entirely. They’re not attached to a smoke stack. They use massive fans to pull in ambient air and chemical filters to bind the CO2, which is then released with heat. The energy requirement is high, which is why Orca’s location next to a geothermal power plant in Iceland is genius—it provides constant, clean, cheap heat and power.

At 4,000 tons per year, its scale is tiny compared to the million-tonne giants. But calling it insignificant misses the point. Orca, and its larger successor Mammoth, are the Boundary Dams of the DAC world. They are proving the integrated process works, optimizing modular design for mass production, and crucially, partnering with Carbfix to permanently mineralize the CO2 by injecting it into basalt rock, where it turns to stone in a few years. This addresses the biggest public concern about CCS: permanence. The success of Orca isn’t in its current tonnage; it’s in de-risking the entire DAC-with-storage model for investors and policymakers.

What Actually Makes a Carbon Capture Project Successful?

Looking across these projects, a pattern for success emerges. It’s never just about the technology widget.

1. A Clear Economic Driver or Support Structure. No project survives on goodwill alone. Boundary Dam and Petra Nova had EOR. Quest and the Illinois project had significant government co-funding to cover the “first-of-a-kind” premium. Orca sells high-purity carbon removal credits to corporations like Microsoft and Stripe. A viable revenue stream is non-negotiable.

2. The Right Geology and Location. This is the silent make-or-break factor. You need a suitable, well-understood, and permitted storage site (saline aquifer or EOR field) within a feasible pipeline distance. The Illinois and Quest projects spent years on seismic imaging and monitoring to ensure safety and public trust. A great capture technology is useless if you have nowhere to put the CO2.

3. Strong, Patient Partnerships. These are complex, capital-intensive projects. They almost always involve partnerships between industry, government, research institutions, and sometimes even NGOs. The shared risk and pooled expertise are critical.

4. Community and Regulatory Engagement from Day One. This is the expert insight many technical plans gloss over. The Illinois Basin project is a masterclass here. They held countless town halls, installed live monitoring data for the public, and involved local universities. They turned potential opponents into stakeholders. A project can have perfect engineering and still fail if the local community fears it.

The Road Ahead: Replicating Success Isn't Simple

So we have successful projects. Can we just copy-paste them everywhere? Not quite.

The biggest hurdle now is economics at scale without massive subsidies. The learning curve from these first projects has brought costs down, but carbon capture is still an added cost for most industries. Wider deployment needs a stronger carbon price (via tax or trading) and policies like the expanded 45Q tax credit in the US to bridge the gap.

Infrastructure is another monster. We need a network of CO2 pipelines and hubs—a whole new piece of national infrastructure. The success of the Alberta Carbon Trunk Line (which now carries CO2 from multiple sources) shows it’s possible, but permitting and building it is slow.

Finally, the narrative needs to shift. The success of these projects shows carbon capture is a viable niche tool for hard-to-abate sectors and carbon removal. It’s not a silver bullet to excuse business-as-usual for fossil fuels. The next wave of projects, like those targeting cement plants, need to be judged on whether they decarbonize essential industries that have no other path to zero.

The evidence from the field is clear. Successful carbon capture projects are not a myth. They are industrial realities that have moved from the drawing board to operations, capturing millions of tonnes of CO2. They’ve faced and overcome brutal technical, economic, and social challenges. Their success doesn’t mean the technology is now cheap or easy. It means the foundational engineering works, the storage is safe, and the operational know-how exists. The question is no longer “can it be done?” but “how do we do it more, better, and cheaper where it’s genuinely needed?” The blueprints, written in steel and concrete by these pioneering projects, are now on the table.
