Carbon storage: caught between a rock and climate change

Carbon storage: caught between a rock and climate change, Professor Herbert Huppert FRS

Royal Society TV presents: Professor Herbert Huppert lecture on Carbon Storage technology.

This technology may combat the rise in greenhouse gases by storing CO2 in vast porous geological formations. For the last fifteen years there has been considerable effort devoted to storing some of the millions of tons of CO2 resulting from the burning of fossil fuels which otherwise would have been emitted into the atmosphere.

Fluid dynamics leakage experiment, theory of up - down stream extend. Storage efficiency, linear in time past leakage point.

Effects

  • Gravity and larger permeability act in opposition
  • Anisotropic heterogeneous permeability
  • Chemical Reactions with hot rock
  • Convection thermal and/or volatile/dissolution driven)
  • Possible dissolution leading to changes in viscosity and density
  • Mineralisation

Conclusions

  • Fluid mechanics can help quantitatively in the interpretation of carbon dioxide injection and spreading
  • Simple models for flow in one layer describe aspects of the evolution at Sleipner (oldest storage site)
  • Convective dissolution of carbon dioxide into the surrounding brine can be quantified
  • Leakage through a fracture can be substantial

Economics of capturing carbon is not part of the lecture.

    Carbon capture is a great idea guaranteed to pay one’s mortgage and make boat payments. As a carbon mitigation method it is brain dead.

    And Prokaryotes, great web page. Congratulations.

    • Thanks John. Though the lecture is interesting in regards to fluid dynamics but it disappoints me a bit considering the work of the RS in regards to Biochar. Carbon sequestration is a potential major instrument to help us reduce atmospheric Co2 emissions. Because a BECCS approach with the production of Biochar is saver and has more advantages.

      Biochar is a key technology for reaching low carbon dioxide atmospheric concentration targets.

      The negative emissions that can be produced by BECCS has been estimated by the Royal Society to be equivalent to a 50 to 150 ppm decrease in global atmospheric carbon dioxide concentrations and according to the International Energy Agency, the BLUE map climate change mitigation scenario calls for more than 2 gigatonnes of negative emissions with BECCS in 2050. http://en.wikipedia.org/wiki/Bio-energy_with_carbon_capture_and_storage
