Consortium wins $3 million in federal funding to study the feasibility of a first-of-a-kind hub for direct air capture in the Pacific Northwest

The consortium of leading scientists, technology developers, and nonprofit organizations will study the feasibility of deploying innovative technology to permanently remove past carbon dioxide emissions from the atmosphere and store them in subterranean basaltic rock in the Pacific Northwest, powered by the region’s significant low-carbon energy resources.

Boulder, CO – August 11, 2023

Thirteen organizations from across sectors — convened by the clean energy nonprofit RMI, the carbon mineralization company Carbfix, and the Pacific Northwest National Lab (PNNL) — have been awarded $3 million by the US Department of Energy (DOE) to study the feasibility of a regional hub for direct air capture (DAC), carbon mineralization, and carbon management in eastern Washington and neighboring states.

The Ankeron Carbon Management Hub would demonstrate technologies that extract legacy carbon emissions from the atmosphere and either utilize or permanently store them. The Pacific Northwest region is uniquely positioned to host a carbon management hub thanks to its abundant renewable energy sources as well as its unique geological formations suitable for turning billions of tons of carbon dioxide (CO2) into stone via mineralization. The hub project will help advance President Joe Biden’s Justice40 Initiative with a focus on community benefits and economic development, clean energy deployment, and spurring innovation in carbon management technologies.

The UN Intergovernmental Panel on Climate Change (IPCC) found that — alongside immediate and rapid cuts to fossil fuel emissions — eliminating existing emissions from the atmosphere through carbon dioxide removal (CDR) solutions, including DAC, will be critical to meeting the goals of the Paris Agreement. The Ankeron Hub will aim to demonstrate a viable pathway for DAC to reach the DOE Carbon Negative Shot target of <$100/ton of durable CO2 removals by 2032. ​

The two-year award, provided under the Bipartisan Infrastructure Law’s Regional Direct Air Capture Hubs program, will fund initial work conceptualizing, designing, and assessing the feasibility of building a hub.

“We need tools to remove carbon from the atmosphere that are sustainable at scale. DAC technology is a promising candidate. The decisions that DAC hubs make this decade on technology, energy, and community benefits will have a massive impact on how DAC evolves and scales,” said Daniel Pike, principal of the Carbon Dioxide Removal Initiative at RMI and the project’s director.Our consortium is determined to get it right. As we assess the feasibility of this concept, we will hold ourselves accountable to local communities and the scientific community. We will find ways to build up clean energy systems in the region, not overload them.”

RMI will lead the design of the hub’s governance and business model while Carbfix and PNNL will lead many scientific and technical elements of the study. Other partners for this first phase include AES, the leading developer of clean energy in the United States, and a suite of leading climate technology developers: Blue Planet, Heirloom, LanzaTech, Removr, Sustaera, and Twelve. Washington State University Tri-Cities will support community engagement for the project, and the Washington State Department of Natural Resources will serve as a technical advisory partner. Fluor will serve as the integrating EPC provider.

The consortium expects and intends to add additional partners, should it advance to future phases.

“Averting the climate crisis requires capturing and storing historical CO2 emissions, in addition to other efforts. We are proud and excited to contribute our proven carbon mineralization technology to this important project in collaboration with outstanding partners,” said Dr. Bergur Sigfússon, head of CO2 Capture and Injection at Carbfix and its principal investigator for the project. “Scientific integrity is key as we move both existing and developing mitigating technologies to scale to achieve climate recovery. In this we will continue to hold ourselves to the highest standards, building on more than a decade of successful operational experience of mineralizing CO2 in Iceland.”

Three DAC companies will participate in this initial phase. Their technologies have high potential, can be powered entirely by electricity, and are well-suited to the region. The companies will work with RMI, Carbfix, and PNNL to assess the technological and economic feasibility of demonstrating their technologies in the region, through a hub that delivers carbon removal, a stronger clean energy system, high-quality local jobs, and benefits to local communities and environments.

“Just a few months after Heirloom’s world-first storage of atmospheric CO2 into concrete, we’re thrilled to see that the Ankeron Hub has been selected by the DOE because it opens up the exciting new frontier of carbon mineralization as a permanent storage method for CO2. We’re looking forward to bringing our nature-inspired Direct Air Capture technology — that harnesses the natural power of limestone to pull CO2 from the atmosphere — to the Ankeron Hub,” said Max Scholten, Head of Commercialization at Heirloom.

In the feasibility study, Ankeron will center community engagement in the hub design and community benefits plan. Two deeply rooted local institutions, PNNL and the Washington State University Tri-Cities, will drive this work. Both possess deep local experience in workforce development, community engagement, and outreach related to complex energy and geology projects.

“I am thrilled that WSU Tri-Cities students will be at the forefront of DAC research and community outreach activities in partnership with PNNL,” said Jillian Cadwell, Research Associate and Adjunct Professor of Civil Engineering at Washington State University Tri-Cities. “As we work to educate the workforce of the future, this opportunity is right in line with our Empowering the Future Energy Workforce plan and what the work students are doing through the Clean Energy Ambassadors Network.”

The Ankeron Hub is one of several projects selected for the first round of DOE funding in a process that will eventually select four DAC hubs across the United States, drawing on a total of $3.5 billion in federal funding. Each hub must prove it can capture from the air and then store or utilize at least one million metric tons of CO2 per year, as well as create high-quality job opportunities.

“This project brings together three fields of carbontech — DAC, carbon mineralization and carbon utilization — into one hub,” said Curt Graham, Office of Technology Vice President at Fluor. “We are excited to collaborate with innovative leaders in the CDR space while using our experience in Washington State and carbon management to advance sustainable solutions that support climate goals.”

“At Removr, we look forward to investing in the Pacific Northwest to deploy our proven, safe, and energy-efficient technology for large-scale atmospheric carbon removal. We feel privileged to be contributing our decades of energy infrastructure expertise from Norway to such a strong, innovative, and diverse consortium,” said Einar Tyssen, CEO at Removr.

“We are excited for the opportunity to further develop the feasibility of a DAC hub in the Pacific Northwest with RMI and their partners,” said Ben Gardner, CEO of Sustaera.

“Collaboration is essential for creating a just, regenerative, and climate-positive future. We look forward to working with the other members of the Ankeron DAC Hub to revolutionize the transformation of captured CO2 through the development of DAC technology. This innovation enables society to have the fuels and materials that drive our economy without relying on fossil fuel extraction,” said Nicholas Flanders, Co-Founder and CEO of Twelve.

“Blue Planet takes immense pride in its role as a carbon utilization partner within Ankeron’s DAC Hub, the successful recipient of DOE funding for groundbreaking carbon removal solutions. Our established expertise in carbon mineralization technology, which facilitates the permanent sequestration of CO2 within concrete aggregate, addresses the pressing need for multiple carbon removal strategies. Through collaboration with the hub’s exceptional partners, we continue to advance innovation to provide gigaton-scale solutions to carbon dioxide mitigation and removal,” said Laura Berland-Shane, Vice President of Government Affairs at Blue Planet.
