CO2 Sequestration
1. To what extent,
the concept of ‘impelling force’
introduced by Hubberts
would be able to provide
a useful means of
visualizing
the net forces acting on CO2?
2. If the impelling force represents
the negative of the gradient in CO2/brine potential,
will it still remain to be a vector quantity
that would precisely define
the direction
in which
CO2 would tend to migrate,
considering
capillary effects?

The concept of "driving forces" introduced by Habert could play an important role in understanding and modeling the net forces acting on CO2, especially in the context of atmospheric and climate sciences. This concept is used to analyze and describe the dynamics of gases and other components in the atmosphere, as well as their impact on climate change.
In this context, driving forces can be considered as factors influencing the concentration of CO2 and its dynamics in the atmosphere, such as:
Net forces on CO2 could be described as the difference between the driving forces that increase CO2 in the atmosphere and those that remove it. For example, if human activities and natural sources of CO2 exceed absorption by the oceans and plants, the net force will be positive, meaning an increase in CO2 concentration in the atmosphere. Conversely, if natural absorption processes become stronger, the net force will be negative, potentially leading to a reduction in CO2 in the atmosphere.
