Emerging space: Carbon capture

Carbon capture refers to the process of actively capturing carbon atoms and removing them from the atmosphere via storage or utilization in other forms.

The private markets are constantly evolving, and new spaces rise—then sometimes fall—in the span of a few years. Given this fluidity, it can be challenging to identify and track the most promising spaces of tomorrow. That’s why our analysts have developed a methodology to define and categorize these emerging spaces. In this post, we look at carbon capture—just one example of a space that is quickly taking off.

What is carbon capture?
Carbon capture refers to the process of actively capturing carbon atoms and removing them from the atmosphere via storage or utilization in other forms. This area has grown quickly as the need to act on climate change becomes more apparent and greenhouse gases continue to accumulate. Technologies in this category are therefore centered on climate change mitigation and include afforestation, biochar, carbon sequestration and direct air capture. Though these technologies only address one piece of a much broader issue, this space could be a critical component for years to come.

Carbon capture is one of many climate tech-related terms to know. To explore dozens of others—broken down by transportation, energy, materials and resources, industry, agriculture, adaptation and buildings—check out our climate tech glossary.

Trending carbon capture companies

Carbon Engineering

  • HQ: Squamish, BC, Canada
  • Leadership: Steve Oldham, CEO, David Keith PhD, founder, board member and acting chief scientist, and others
  • Latest funding: $18.7M, Grant (June 26, 2019)

Carbon Engineering‘s Direct Air Capture (DAC) technology captures carbon dioxide directly from the air with an engineered, mechanical system. It does this by pulling in atmospheric air, then through a series of chemical reactions, extracting the CO2 from it while returning the rest of the air to the environment. The company’s website says it’s similar to what plants and trees do every day as they photosynthesize—except DAC does it faster, with a smaller land footprint and delivers CO2 in a pure, compressed form that can then be stored underground or reused.


  • HQ: Skokie, IL
  • Leadership: Jennifer Holmgren, PhD, CEO and board member
  • Latest funding: $72M, Series E (August 2019)

LanzaTech developed a bio-processing platform to improve waste carbon treatment. The startup’s platform manufactures low-carbon fuels made from the industrial waste of steel mills, oil refineries and chemical manufacturers.


  • HQ: Zurich, Switzerland
  • Leadership: Christoph Gebald, PhD, co-CEO, director and board member
  • Latest funding: $107.41M, late-stage VC (August 2020)

Climeworks is the developer of carbon removal technology designed to capture CO2 from air. Founded in 2009, the company’s carbon removal technology offers novel process and filters material that sucks environmental friendly CO2 which helps in the production of carbon-neutral renewable fuels and storage of renewable energies, enabling organizations to capture, store and generate energy from carbon.
