Carbon Capture Explained: Is It Really Worth it?

You know me: I’m always trying to understand the latest “big climate solutions” people are talking about. And lately, I keep hearing about carbon capture — a super-fancy idea that sounds like a giant vacuum cleaning up the sky. ExxonMobil loves to tout it as a “real solution” to address climate change.

But does it really work? And can it help our kids and grandkids grow up on a healthy, stable planet?

Let’s look into this together.

Okay… What Is Carbon Capture, Really?

Carbon capture is a set of technologies that try to grab carbon dioxide (CO₂) before it escapes into the air — or pull it straight from the air after it’s already there.

The idea is simple:
Less CO₂ in the sky = less warming for Earth.

But of course, the real story is far more complicated (isn’t it always?).

Where Carbon Capture Actually Helps

There are places where carbon capture can make a difference — especially in industries where pollution is hard to avoid.

1. Cement factories

Making cement naturally creates CO₂. Even if you used 100% clean energy, it would still happen. Carbon capture can help catch some of that unavoidable pollution.

2. Steel production

Steel plants create a lot of CO₂ too, and we don’t yet have perfect clean substitutes. Capturing the carbon here can help.

3. Some bioenergy systems

If you burn plant material for energy and capture the CO₂, you can reduce emissions — but only if the plants are grown in a sustainable way that doesn’t hurt ecosystems.

4. Certain chemical factories

A few industries (like making fertilizer or hydrogen) release CO₂ from one main source, which is easier to capture.

These are the “sweet spots” where carbon capture can be useful.

Where Carbon Capture Just Doesn’t Make Sense

Now for the tricky part. Let’s just say, it’s not going to save us.

1. Fossil-fueled power plants

Here’s the truth: it’s usually cheaper and cleaner to switch to wind or solar than to try capturing carbon from a coal or gas plant.

2. Direct Air Capture (the sky vacuum!)

Direct air capture real. Machines that suck CO₂ out of thin air exist. But:

• They use tons of energy
• They capture tiny amounts of CO2 compared to emissions from human activities
• They’re extremely expensive

Cool idea! Not a climate superhero.

3. “Offsets” companies use to avoid real change

Some companies use carbon capture as an excuse to keep polluting.
That’s not helping the planet — it’s just greenwashing.

Why Fossil Fuel Companies Love Carbon Capture

You’ve probably noticed big polluters like ExxonMobil and Chevron are talking about carbon capture like it’s the miracle we’ve been waiting for.

Here’s why:

1. It lets them say, “Don’t worry, we’ve got this!”

Instead of transitioning to clean energy, they can claim they’ll just “capture the carbon.” Spoiler: they rarely capture as much as they promise.

2. It keeps old power plants running longer

Carbon capture gives fossil fuel companies a reason to delay shutting down polluting plants.

3. They already use CO₂ to pump out more oil

There are fewer than 20 carbon-capture projects running in the U.S. right now, and most of them don’t actually help the climate. Instead, they use the captured carbon to push more oil out of the ground, in a process called “enhanced oil recovery.”

4. It comes with big government subsidies

In some cases, carbon capture pays companies more than actually reducing pollution would.

Final Thoughts

Carbon capture might sound like science fiction, but it’s one of many tools we have as we work to protect our planet. It’s far from perfect, and it’s not close to being powerful enough to solve climate change on its own, But, in the right situations, it can help reduce the pollution we can’t easily avoid.

The real change still comes from cutting emissions to net zero in the first place, choosing clean energy, and standing up for the future we want our kids and grandkids to inherit. And the more we understand these technologies, the harder we can push back against the hype, the shortcuts, and the greenwashing.

We’re all learning together — and every bit of learning brings us one step closer to the healthier, safer world our young people and living species deserve. 💚
