... selected ideas in the following categories: Unconventional CO2 storage formations; increased use of CO2 in enhanced oil recovery; Microbial hydrogen generation from fossil filets at depth, with subsurface fuel cell coupling; and Deep-sea contained storage. UNCONVENTIONAL CO2 STORAGE FORMATIONS Deep, long-term underground storage of CO2 is being conclucted today in various parts of the florid in depleted reservoirs.

... Possible research concepts include the following: 6 Charactenzation of promising, previously unstudied porous rock mass formations Tom a storage media perspective. This investigation would include examining porosity, permeability, capacity, and chemical composition.

... This would avoid the near-certain loss of valuable storage space when the oil reservoir is completely depleted before it is ever reengaged to serve as a storage medium. Possible research concepts include the following: · Identifying economical means of transporting CO2 Tom energy-producing plants to the oil fields and quantifying costs in rough orders of magnitude; · Identifying additional infrastructure requirements and costs to employ EOR on many more reservoirs than those that current practice uses; Identifying the potential for CO' consumption through EOR if EOR were used in · .

... It may be possible to harvest energy from the hydrocarbon oxidation using an electrode configuration. In situ application of this technology would be highly desirable from an environmental standpoint, because energy generation would occur in the subsurface, minimizing the environmental impacts of mining the fossil fuel, bringing the material to the surface, and processing it at existing power plants.

... Ordinary leakages would be comparatively benign. First estimates of infrastructure development, costs, and time appear to be far less than estimates for sequestering CO2 in traditional subsurface storage formations, given that the volume of CO2 that needs to be sequestered is equal to or greater than the total production capacity of the global petroleum industry.
