Capturing Tomorrow: How Carbon Capture and Storage Can Help Save the Environment

As the climate crisis intensifies, the global community is urgently seeking technological solutions that go beyond reducing emissions to actively removing carbon dioxide (CO₂) from the atmosphere. Among the most promising tools in this fight is Carbon Capture and Storage (CCS)—a process that captures CO₂ emissions from industrial sources and stores them deep underground, preventing their release into the atmosphere.

Once a fringe idea, CCS is now at the center of climate policy debates. Advocates see it as a necessary bridge to a low-carbon future, especially for hard-to-abate industries like steel, cement, and petrochemicals. Detractors worry that it may be used as a license to delay decarbonization.

Still, with global emissions rising and climate targets looming, the role of CCS in complementing renewable energy and energy efficiency is gaining attention—and funding.

“Carbon capture is not a silver bullet, but it is a critical tool in our climate toolbox,” says Fatih Birol, Executive Director of the International Energy Agency (IEA). “Without it, achieving net-zero emissions will be far more expensive and difficult.”

What is Carbon Capture and Storage (CCS)?

CCS involves three key steps:

1. Capture: CO₂ is separated from gases produced during industrial processes or energy generation.
2. Transport: The CO₂ is then compressed and transported—usually via pipeline—to a storage site.
3. Storage: It is injected deep underground into geological formations such as depleted oil and gas fields or deep saline aquifers, where it is permanently stored.

According to the Global CCS Institute, there are currently 41 commercial CCS facilities in operation or under development worldwide, with a total capture capacity of over 111 million tonnes of CO₂ per year—a figure expected to grow significantly in the next decade.

Why CCS Matters for the Environment

Climate scientists agree that to limit global warming to 1.5°C, the world must not only reduce emissions but also remove carbon from the atmosphere. CCS allows for:

• Mitigation of emissions from essential industries that can’t yet operate on renewable energy.
• Net-negative emissions, especially when combined with bioenergy (BECCS) or direct air capture (DAC).
• Support for hydrogen production, where CCS is used to reduce the carbon footprint of hydrogen made from natural gas.

“CCS plays an indispensable role in pathways to net zero, especially when applied to sectors that lack clean alternatives,” says Dr. Jennifer Wilcox, a leading carbon removal expert and Principal Deputy Assistant Secretary for Fossil Energy and Carbon Management in the U.S.

Real-World Applications and Projects

Several major CCS projects are already demonstrating the potential of the technology:

• Norway’s Northern Lights Project: A flagship CCS initiative that aims to create a full-scale open-source transport and storage infrastructure for CO₂ in the North Sea.
• Canada’s Quest Project: Operated by Shell, this facility has captured and stored over 6 million tonnes of CO₂ since 2015 from hydrogen production.
• Petra Nova (U.S.): Although temporarily paused, it remains a landmark in demonstrating CCS on a coal-fired power plant.

Emerging projects in India, Australia, the Middle East, and China also show growing interest from both public and private sectors.

Environmental Benefits and Opportunities

If deployed responsibly, CCS can offer multiple benefits to the environment:

• Reduced atmospheric CO₂: By preventing emissions from reaching the air, CCS slows the accumulation of greenhouse gases.
• Cleaner air: Many CCS systems also reduce co-pollutants like sulfur dioxide and nitrogen oxides.
• Support for sustainable industry: CCS allows sectors like steel and cement to decarbonize without shutting down—protecting jobs and industrial capacity.
• Carbon-negative potential: When paired with biomass or direct air capture, CCS can actually remove more CO₂ than it emits.

Challenges and Criticisms

Despite its promise, CCS faces significant challenges:

1. High Costs

CCS is still expensive. Capturing one tonne of CO₂ can cost between $50 and $150, depending on the source and technology. Without carbon pricing or government incentives, it’s often not economically viable.

2. Energy Demand

CCS itself requires energy, which can reduce the overall efficiency of the host plant. This is sometimes referred to as the “energy penalty.”

3. Long-Term Storage Risks

Though considered safe by most geologists, concerns remain about CO₂ leakage from underground storage sites over long periods.

4. Moral Hazard

Some environmentalists worry that CCS may serve as a “get-out-of-jail-free card” for fossil fuel industries, allowing them to prolong oil and gas production under the guise of mitigation.

“Carbon capture cannot be an excuse for business-as-usual,” warns Greta Thunberg, climate activist. “It must complement—not replace—bold emissions cuts and renewable energy deployment.”

Policy Momentum and Global Investment

Governments worldwide are pouring money into CCS. The United States’ Inflation Reduction Act offers up to $85 per tonne of CO₂ stored, making CCS more financially attractive. The European Union’s Green Deal and Canada’s CCUS Tax Credit also allocate billions to accelerate adoption.

Meanwhile, oil and gas companies are repositioning themselves as carbon management firms. Occidental Petroleum, for example, has launched a subsidiary focused entirely on direct air capture and geological storage.

“We are no longer just an energy company—we are a carbon management company,” said Vicki Hollub, CEO of Occidental.

Public Perception and Community Engagement

Public support is growing but cautious. Transparency, rigorous monitoring, and meaningful engagement with communities near storage sites are essential. Success will depend on trust, regulation, and science-based risk communication.

“We need to treat CCS like a public utility—accountable, safe, and in service of the common good,” says Professor Julio Friedmann, Chief Scientist at Carbon Direct and former DOE official.

The Road Ahead: Integrated Climate Strategy

CCS isn’t a silver bullet—but in tandem with renewables, energy efficiency, reforestation, and behavioral shifts, it forms part of a multi-pronged strategy to achieve a livable climate.

According to the Intergovernmental Panel on Climate Change (IPCC), all modeled pathways to 1.5°C that avoid overshooting rely on some form of carbon removal, including CCS.

The technology’s success will depend on scaling responsibly, balancing investment with real climate gains, and ensuring it complements—rather than competes with—other green technologies.

Conclusion

In a world where time is running out to curb the climate crisis, Carbon Capture and Storage offers both promise and peril. If deployed transparently, responsibly, and in harmony with deep decarbonization, CCS could become one of the pillars of a just and sustainable future.

As nations strive to reach net-zero, CCS reminds us that sometimes the best solutions lie beneath our feet—capturing what we can no longer afford to release.
