Who is Who in Direct Air Capture

Here is a subjective list of key players and experts in the global Direct Air Capture ecosystem, compiled by Julius Wesche (PhD); Climate Innovation Researcher at the Norwegian University of Science and Technology, Trondheim, Norway. The list will be continuously updated, based on suggestions and comments.

Direct Air Carbon Capture and Storage Market Scan

by Lucía Vilallonga & Cutler J. Cleveland

In this report, the Institute for Global Sustainability synthesizes scientific literature, industry reports, government policies, and news to assess the potential for DACCS as a compliance pathway in local emissions reduction ordinances and other regulations, for example by the City of Boston through the Building Emissions Reduction and Disclosure Ordinance 2.0 (BERDO 2.0).

Borchers et al. (2022): Contribution to Net-Zero-2050 Germany – the portfolio of carbon dioxide removal options

Malgorzata Borchers, Daniela Thrän, Yaxuan Chi, Nicolaus Dahmen, Roland Dittmeyer, Tobias Dolch, Christian Dold, Johannes Förster, Michael Herbst, Dominik Heß, Aram Kalhori, Ketil Koop-Jakobsen, Zhan Li, Nadine Mengis, Thorsten B. Reusch, Imke Rhoden, Torsten Sachs, Cornelia Schmidt-Hattenberger, Angela Stevenson, Terese Thoni, Jiajun Wu, Christopher Yeates IN: Front. Clim. Sec. Negative Emission Technologies, doi: 10.3389/fclim.2022.810343

The authors investigated various near-to-market CDR options for Germany, which the authors present in the form of thirteen dedicated model concepts. They cover technical CO2 removal (two models of direct air carbon capture, i.e. DACC), hybrid solutions (six bioenergy with carbon capture technologies, i.e., BECC) and five options for natural sink enhancement, so-called Nature-Based Solutions (NBS).

Nature – Diederichsen et al. (2022): Electrochemical methods for carbon dioxide separations

Kyle M. Diederichsen, Rezvan Sharifian, Jin Soo Kang, Yayuan Liu, Seoni Kim, Betar M. Gallant, David Vermaas, T. Alan Hatton IN: Nature Reviews Methods Primers 2, 68 (2022). https://doi.org/10.1038/s43586-022-00148-0

The authors provide an overview of the experimentation and analysis needed for the study of electrochemical methods for CO2 separation, including a discussion of the considerations necessary for targeting the application of such techniques. The article focuses on ambient temperature techniques such as pH swing and direct redox processes, which utilize similar experimental set-ups.

Ishaq & Crawford (2022): Potential of offshore wind energy for direct air capture

Haris Ishaq & Curran Crawford IN: International Journal of Energy Research, https://doi.org/10.1002/er.8506

The authors develop a conceptual design and conduct an energy assessment of two dominating DAC designs to show the potential of offshore wind to meet the DAC energy demand for two different scenarios capturing 3.3 GtCO2/y (10%) and 11 GtCO2/y (33.3%) of current global CO2 emissions covering a range of estimates for future NETs required to meet net-zero goals.

New law helps U.S. firm launch Wyoming direct air carbon capture project

by Reuters on nbcnews.com

„A Los Angeles-based company kicked off on Thursday what it said will be the first large-scale direct air capture (DAC) project to capture and store 5 million tons of carbon dioxide per year by 2030, benefiting from new U.S. government incentives. […] CarbonCapture, founded by technology entrepreneur Bill Gross, announced the start of Project Bison in Wyoming with Frontier Carbon Solutions, marking a milestone as government and private investment pours into the nascent DAC climate technology. […] The passage in August of new law by Congress accelerated the launch of Project Bison by a couple months, giving CarbonCapture and the DAC industry the financial support and long-term certainty needed to scale up the technology, CarbonCapture CEO Adrian Corless told Reuters.“

Capture 6

…is a Public Benefit Corporation with offices in Berkeley, California, USA and Rotorua, NZ. Capture6 focuses on enhanced approaches to capturing greenhouse gases from the atmosphere (direct air capture). Their innovation is driving down the cost of carbon removal to less than $100 USD per tonne today. Capture6 has developed the SPACERSTM framework to describe their CDR approach, which is based on the „Oxford Principles on Carbon Offsetting“ that calls for moving to CDR that is permanent, irreversible, and with a small physical footprint to not displace or impact local communities.

Where will Heirloom’s Direct Air Capture facilities be deployed?

Heirloom on medium.com

Heirloom „…want to share some insight into how they are thinking about siting and deployment of their DAC facilities in the US. […] All DAC technology relies on three core inputs: land to site on, energy to drive CO2 absorption and/or desorption, and access to CO2 pipelines to transport CO2 gas to permanent geological storage (or direct access to geologic storage itself). […] A map highlights a few key locations of interest for Heirloom: San Francisco, CA; Columbia River Valley, WA as well as East Texas and Louisiana.“

„This Startup Is Enhancing the Ocean’s Ability to Store Carbon, Reversing Acidification“

by Scarlett Buckley on sustainablebrands.com

„Ebb Carbon’s pioneering carbon-removal technology combines with electrochemistry to accelerate the ocean’s natural process of carbon removal, safely storing it for 10,000+ years, whilst simultaneously reducing ocean acidity […] The electrochemical process works by intercepting the saltwater that saltwater-treating facilities deposit back into the ocean and adjusting the electricity of its molecules — the salt and water molecules in saltwater are rearranged to produce acid and slightly alkaline saltwater solutions. When this alkaline saltwater returns to the ocean, a natural chemical reaction occurs — and CO2 is pulled out of the air and stored as bicarbonate.“
