Ask "who is developing carbon capture technology?" and you'll get a flood of names—tech billionaires, oil giants, Swiss startups. It's noisy. After looking at this space for a while, I see a clear split. The real development isn't led by one group. It's a messy, competitive, and sometimes conflicting race between three distinct camps, each with a different goal, technology, and definition of success.

One camp wants to clean up existing industry. Another wants to reverse historical emissions. The third is trying to build a whole new energy system. Understanding who's who isn't just a list; it tells you what future we're actually building.

The Three Main Camps of Carbon Capture Developers

Forget a single list. The developers separate cleanly by their primary objective, which dictates their technology choice.

Point-Source Capture vs. Direct Air Capture (DAC) is the first big fork. Point-source grabs CO2 from smokestacks (cement, steel, power plants). DAC sucks it from the ambient air. The former is cheaper now, prevents new emissions. The latter is far more flexible and removes old emissions, but it's energy-hungry and costly.

The table shows the divergence. An oil company isn't trying to solve the same problem as a Silicon Valley-backed DAC startup. They're in different races.

Camp 1: The Industrial Incumbents (Scaling What Works)

This group gets less flashy headlines but owns most of the existing global capture capacity. Their playbook is evolution, not revolution.

Oil & Gas Majors: The Scalers with a Mixed Motive

ExxonMobil is arguably the 800-pound gorilla in this space. They've been capturing CO2 for decades for Enhanced Oil Recovery (EOR). Their focus is on scaling up point-source technology, particularly for heavy industries. Their flagship project is the Houston CCS Innovation Zone, aiming to store 50 million tons annually by 2030 by aggregating emissions from nearby chemical and manufacturing plants. The technology? Often a licensed amine-based solvent process they've optimized.

Chevron and Shell follow similar paths, investing in large-scale projects like the Gorgon CO2 Injection Project in Australia and the Quest project in Canada. Their advantage is unparalleled expertise in subsurface geology for storage and massive project management for billion-dollar endeavors.

Here's the uncomfortable truth: for many of these projects, the business case still leans heavily on EOR—pumping CO2 to get more oil out. The "abated" oil argument is contentious. Their development is real, but the net climate benefit is the subject of fierce debate.

Industrial Engineering Giants: The Technology Licensors

These are the companies that actually design and sell the capture hardware.

Mitsubishi Heavy Industries (MHI) and its partner Kansai Electric Power have their KM CDR Process technology installed in over a dozen plants worldwide. If you see a carbon capture unit on a coal plant or steel mill, there's a decent chance it's theirs. They're pragmatic, focusing on making a reliable, if not cheap, product for a niche industrial clientele facing carbon taxes.

Fluor, with its Econamine FG Plus technology, is another key player in this licensor space.

These firms aren't betting the company on carbon capture. It's a product line. Their development is cautious, iterative, and driven by specific client demand, not climate vision.

Camp 2: The DAC Startups & Pure-Plays (Betting on a New Frontier)

This is the glamorous, venture-funded face of carbon capture. Their entire reason for existing is carbon removal.

Climeworks (Switzerland) is the most visible. Their Orca plant in Iceland, using a solid sorbent filter technology and geothermal energy, put DAC on the map. Their model is B2B, selling multi-year carbon removal contracts to companies like Microsoft and Stripe. They're now scaling to their Mammoth plant. The challenge? Even at scale, their costs are high—hundreds of dollars per ton. Their bet is that massive scale and learning curves will bring it down.

Carbon Engineering (Canada/US) took a different path. Instead of building its own plants at full scale, it focused on perfecting its liquid solvent DAC technology and licensing it. This led to its acquisition by Occidental Petroleum for $1.1 billion. Oxy plans to use the tech for both carbon removal and, notably, for EOR in its oil fields. It's a fascinating example of a startup vision colliding with industrial reality.

Other notable entrants include Heirloom (using accelerated weathering of minerals), Global Thermostat (an early pioneer), and Carbyon (promising a more energy-efficient process).

Camp 3: The Full-System Builders & Innovators

This camp knows capture is just one piece. You need to move the CO2 and lock it away permanently. Or better yet, design a system where capture is inherent.

Aker Carbon Capture (Norway) exemplifies this. They don't just sell a capture module; they offer the whole chain—engineering, capture plant, transport logistics. They're thinking in terms of CCS hubs, like the one they're developing in Norway's industrial south.

NET Power is a radical example. They didn't try to bolt capture onto a gas plant. They designed a new power cycle (the Allam Cycle) that uses supercritical CO2 as the working fluid. The result? A gas plant that inherently produces a pure, pipeline-ready CO2 stream by design. It's a full-system reimagining. Their 50MW demonstration plant in Texas is a critical proof point.

This camp also includes transport & storage specialists like Summit Carbon Solutions, which is building a massive CO2 pipeline network across the US Midwest for ethanol plants. Without them, the captured CO2 has nowhere to go.

How to Think About the 'Who' as an Investor or Policymaker

So who's winning? That's the wrong question. The right question is: which camp's success is necessary for which outcome?

If you're a policymaker trying to decarbonize your country's steel or cement industry, your partners are Camp 1 (Incumbents) and Camp 3 (System Builders). You need point-source technology and a CO2 highway to storage. Subsidizing a DAC plant won't solve your cement emissions.

If you're an investor seeking venture-scale returns betting on a new climate tech category, Camp 2 (DAC Startups) is your arena. It's high risk, but the potential market for durable carbon removal is vast if costs fall and demand (from corporate net-zero pledges) holds.

If you're a corporate sustainability leader buying carbon credits for a net-zero claim, you need to understand this map deeply. A credit from a point-source capture + EOR project (common from Camp 1) is fundamentally different from a verified DAC removal credit (Camp 2). The permanence, additionality, and net impact are worlds apart. Blending them in a portfolio is one thing; conflating them is greenwashing.

The landscape is also shaped by government labs (like NETL in the US or SINTEF in Norway) doing foundational R&D, and by tech giants like Microsoft and Google who are major funders of carbon removal through their procurement.

My view? We need all three camps. We need incumbents to clean up today's mess, startups to invent tomorrow's tools, and system builders to connect it all. But we must be clear-eyed about their different roles, motivations, and the specific problems their technologies solve. The development of carbon capture isn't a unified front; it's a complex, sometimes contentious, ecosystem. And that's exactly what makes it interesting.
