What is direct air capture?

Direct Air Capture (DAC) is a technology that removes carbon dioxide (CO2) from the atmosphere.

Using high-powered fans, air is drawn into a processing facility where the CO2 is separated through a series of chemical reactions. Then the CO2 is either permanently stored in underground reservoirs through secure geologic sequestration, or is used to make new products such as building materials and low-carbon fuels.

Ramping up DAC

Today there are a total of 18 DAC facilities in operation from a number of different companies around the world. All told, they capture just 0.01 million tonnes of CO2 per year.¹

In 2022, 1PointFive began construction on what is expected to be the largest DAC facility in the world, our flagship facility, STRATOS. Once fully operational, our first facility is designed to capture 500,000 tonnes of CO2 per year and expected to begin commercial operations in mid-2025.

Why it's important

According to the sixth Assessment Report from the Intergovernmental Panel on Climate Change (IPCC), “In addition to deep, rapid, and sustained emission reductions, carbon dioxide removal (CDR) can fulfill three different complementary roles globally or at country level: lowering net CO2 or net GHG emissions in the near term; counterbalancing ‘hard-to-abate’ residual emissions (e.g., emissions from agriculture, aviation, shipping, industrial processes) in order to help reach net zero CO2 or net zero GHG emissions in the mid-term; and achieving net negative CO2 or GHG emissions in the long term if deployed at levels exceeding annual residual emissions.”2

How DAC Works

1PointFive is developing Carbon Engineering’s Direct Air Capture technology. This technology works by drawing air into a facility using a series of large fans. The air comes in contact with a chemical solution that binds to the CO2 molecules. The CO2-rich solution is then processed through a series of reactions that separate, purify and compress the CO2. The resulting CO2 can then be permanently stored or used as a feedstock for other products.

For a detailed explanation of the DAC process, watch the video below.

Design one.

1PointFive is working with global EPC Worley on the design and construction of our first facility, STRATOS, using proven processes and equipment.

We’re designing these facilities to leverage modularity in the air contactor systems while taking advantage of economies of scale in a centralized processing facility where the captured CO2 can be aggregated and processed in large volumes.

DAC facilities require electricity to operate the air contactors and processing equipment. All 1PointFive facilities will be powered by zero-emission energy sources, such as wind, solar or NET Power.

Each tonne of CO2 removed from the atmosphere by 1PointFive will be quantified by net lifecycle emissions analysis (LCA) and verified by a third party in compliance with recognized methodologies.

Build many.

As 1PointFive continues its development, we plan to focus on regions that meet the following criteria:

  • Have public policy and incentives that support CO₂ removals in place today or are expected to during this development timeframe
  • Show growing demand for carbon removal credits or low-carbon fuels
  • Possess scalable business attributes such as geologic storage, synthetic fuel production inputs and zero-emission electricity production
  • Have sustainable development goals

Growing Corporate Support

Voluntary support for DAC is increasing in the corporate sector. More and more companies across a wide range of industries are committing to net-zero emissions and seeking solutions to achieve their targets. Industry leaders including Airbus, SK, Shopify, and ThermoFisher have shown early support for 1PointFive DAC.

DAC Economics

The Goldman Sachs Carbonomics 2020 Emission Abatement cost curve includes five gigatons of non-abatable emissions, which DAC can address. Additionally, DAC can provide a lower-cost abatement solution in the near-term for hard-to-decarbonize transportation industries, where the average cost of abatement via alternative fuels exceeds $600/tonne.

1PointFive DAC carbon removal can provide a competitively priced solution for these hard-to-abate sectors.
