Shallow Geologic Storage of Carbon to Remove Atmospheric CO₂ and Reduce Flood Risk.

ABSTRACT: Geologic carbon storage currently implies that CO₂ is injected into reservoirs more than 1 km deep, but this concept of geologic storage can be expanded to include the injection of solid, carbon-bearing particles into geologic formations that are one to two orders of magnitude shallower than conventional storage reservoirs. Wood is half carbon, available in large quantities at a modest cost, and can be milled into particles and injected as a slurry. We demonstrate the feasibility of shallow geologic storage of carbon by a field experiment, and the injection process also raises the ground surface. The resulting CO₂ storage and ground uplift rates upscale to a technique that could contribute to the mitigation of climate change by storing carbon as well as helping to ada
