This week in the series, four of the teams were introduced that won the Carbon Removal Xprize Milestone award. On April 22nd, Xprize announced the 15 winners of the second round of their competition for carbon removal solutions. Each of these teams was been awarded $1 million to help them compete for the grand prize of $50 million, or 3 $30 million runner-up slots, which will be awarded three years from now.

CSLF Carbon Dioxide Removal Workshop

28 June 2022, Bergen, Norway

The Carbon Sequestration Leadership Forum (CSLF) organises a workshop on Carbon Dioxide Removal, organised by the CSLF, IEAGHG, and CEM CCUS. The workshop will be held on June 28th , 2022, in Bergen, Norway, and will coincide with the next CSLF Technical Group meeting being held the day before. It is an in-person meeting with remote access as well.

Zhu et al. (2022): Unlocking the potential of hydraulic fracturing flowback and produced water for CO2 removal via mineral carbonation

Bizhou Zhu, Siobhan A. Wilson, Nina Zeyen, Maija J. Raudsepp, Ashkan Zolfaghari, Baolin Wang, Ben J. Rostron, Katherine N. Snihur, Konstantinvon Gunten, Anna L. Harrison, Daniel S. Alessi IN: Applied Geochemistry,105345, https://doi.org/10.1016/j.apgeochem.2022.105345

Flowback and produced water (FPW) generated by hydraulic fracturing operations is highly saline and contains elevated concentration of ions including calcium and magnesium. Here, the authors investigate the use of FPW as a source of calcium and magnesium for carbon dioxide (CO2) capture and storage in carbonate minerals.

Sorimachi (2022): Novel Method for CO2 Fixation and Storage Preventing Climate Crisis: an “Artificial Forest” Model

Kenji Sorimachi IN: Petroleum and Chemical Industry Intern, 5(1), pp. 01-04

„In the previously developed method using low NaOH and CaCl2 concentrations, the atmospheric CO2 is simply fixed to CaCO3 and NaCl, which exist as coal or limestone, and a large chamber comprising spray nozzles to capture CO 2 efficiently by mists or droplets of NaOH solution has been designed. In the present study, a polytunnel made of polymer sheets, an “artificial forest” model, which allows CO2 penetration instead of the chamber has been proposed.“

Hansson et al. (2022): The underworld of tomorrow? How subsurface carbon dioxide storage leaked out of the public debate

Anders Hansson, Jonas Anshelm, Mathias Fridahl, SimonHaikola IN: Energy Research & Social Science, Volume 90, 2022,102606,https://doi.org/10.1016/j.erss.2022.102606.

This perspective paper illustrates that the critical debate regarding geological storage of carbon dioxide has been discursively marginalised in recent years.

Regional Carbon Management Applicant Education Workshop

April, 13, 19 and 26, 2022

The U.S. Department of Energy’s Office of Fossil Energy and Carbon Management (DOE-FECM) is announcing the first of three in-person Regional Carbon Management Applicant Education Workshops, to be held at the Hyatt Regency Columbus, Ohio. This three week series of in-person, day-long workshops will bring together stakeholders of large-scale Carbon Management-related infrastructure projects. Following Columbus, in-person events will be held in New Orleans, LA on April 19th; and Salt Lake City, UT on April 26th.

Is there still a case for Carbon Takeback or Carbon Removal Obligations in a world of low renewable energy costs?

Myles Allen, Stuart Jenkins, Matthew Ives, Margriet Kuijper IN: EGU General Assembly 2022, Vienna, Austria, 23–27 May 2022, EGU22-4419, https://doi.org/10.5194/egusphere-egu22-4419, 2022

…to be discussed at the EGU conference (Vienna, Austria & Online, 23–27 May 2022). „The risk of stranding of CCS capacity is directly linked to the long-term cost of both CCS and the extraction costs of fossil fuels, reinforcing the case for delivering CCS through obligations on the fossil fuel extraction industry in order to align incentives and ensure that those who benefit most from continued use of fossil fuels also shoulder the risks associated with the transition.“

[Preprint] Zick et al. (2022): Carbon Dioxide Capture at Nucleophilic Hydroxide Sites in Oxidation-Resistant Cyclodextrin-Based Metal-Organic Frameworks

Mary Zick, Suzi Pugh, Jung-Hoon Lee, Alexander Forse IN: ChemRxiv. Cambridge: Cambridge Open Engage; 2022; not peer-reviewed

The authors provide gas sorption, spectroscopic, and computational studies sup-porting that CO2 chemisorption in γ-cylodextrin-based metal-organic frameworks (CD-MOFs) occurs via HCO3− formation at nucleophilic OH− sites within the framework pores, rather than via previously proposed pathways involving carbonic acid or alkyl carbonate formation.

Solid Carbon: A Climate Mitigation Partnership Advancing Stable Negative Emissions

Solid Carbon is an project to permanently and safely sequester carbon dioxide (CO2) as rock. The vision is to extract CO2 directly from the air or ocean. Then, using deep ocean technology powered by ocean-based wind and solar energy, inject the CO2 into the subseafloor basalt, where it mineralizes into solid carbonate rock. A PICS (Pacific Institute for Climate Solutions) Theme Partnership – Project; began October 1, 2019 with project Duration of four years. Lead PI: Dr. David S. Goldberg; a new explainer video is relased.

Nature – Regnier et al. (2022): The land-to-ocean loops of the global carbon cycle

Pierre Regnier, Laure Resplandy, Raymond G. Najjar, Philippe Ciais IN: Nature 603, 401–410 (2022). https://doi.org/10.1038/s41586-021-04339-9

„Carbon storage by the ocean and by the land is usually quantified separately, and does not fully take into account the land-to-ocean transport of carbon through inland waters, estuaries, tidal wetlands and continental shelf waters—the ‘land-to-ocean aquatic continuum’ (LOAC). Using a mass-balance approach, the authors find that the pre-industrial uptake of atmospheric carbon dioxide by terrestrial ecosystems transferred to the ocean and outgassed back to the atmosphere amounts to 0.65 ± 0.30 petagrams of carbon per year (±2 sigma).“
