Abstract

Developing a method for secure sequestration of anthropogenic carbon dioxide in geological formations is one of our most pressing global scientific problems. Injection into deep-sea basalt formations provides unique and significant advantages over other potential geological storage options, including ( i ) vast reservoir capacities sufficient to accommodate centuries-long U.S. production of fossil fuel CO 2 at locations within pipeline distances to populated areas and CO 2 sources along the U.S. west coast; ( ii ) sufficiently closed water-rock circulation pathways for the chemical reaction of CO 2 with basalt to produce stable and nontoxic (Ca 2+ , Mg 2+ , Fe 2+ )CO 3 infilling minerals, and ( iii ) significant risk reduction for post-injection leakage by geological, gravitational, and hydrate-trapping mechanisms. CO 2 sequestration in established sediment-covered basalt aquifers on the Juan de Fuca plate offer promising locations to securely accommodate more than a century of future U.S. emissions, warranting energized scientific research, technological assessment, and economic evaluation to establish a viable pilot injection program in the future.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The target for CO2 injection in the Juan de Fuca Plate is a volume of 7800 km3 of altered basalt with an average porosity of 10% for a storage potential of 920 Gt of CO2.

    “The target for CO 2 injection is a volume of 7800 km 3 of altered basalt with an average porosity of 10% for a storage potential of 920 Gt of CO 2 .48”
  • In general, steel-making slags require grinding as carbonation pre-treatment, but the cost of mining and transportation to CO2 emission sites can usually be avoided.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
