Abstract: Systems for automated capture and recovery of oil from oil-contaminated water and solids are disclosed. In some embodiments, the systems include the following: a plurality of automated robotic oil recovery units; a plurality of deployable oil collection membranes positioned within each of the units, each of the membranes including an upper half including a material impermeable to both water and crude oil and a lower half including a semi-permeable hydrophilic membrane that is permeable to water but impermeable to crude oil; and a high pressure carbon dioxide oil solids separation unit for separating oil from oil-contaminated solids thereby producing substantially oil-free solids and an oil and carbon dioxide mixture; a solids separation unit for the separating substantially oil-free solids from the oil and carbon dioxide mixture via gravity separation; and an oil separation unit for separating oil from the oil and carbon dioxide mixture using a pressure swing.

Abstract: Methods and systems for sequestering carbon dioxide and generating hydrogen are disclosed. In some embodiments, the methods include the following: dissolving an iron based material that includes a carbonate-forming element into a solution including the carbonate-forming element and iron; increasing a pH of the solution to cause precipitation of iron oxide from the solution thereby generating a first source of Fe2O3; reacting the carbonate-forming element in the solution with a first source of carbon dioxide to produce a carbonate thereby sequestering the carbon dioxide; oxidizing the first source of Fe2O3 with a carbonaceous fuel thereby generating a second source of carbon dioxide and iron; and oxidizing the iron with steam thereby generating hydrogen and an iron oxide. Some embodiments include producing iron-based catalysts.

Abstract: Methods and systems for tagging carbon dioxide to be stored in a geologic formation are disclosed. In some embodiments, a method includes: providing a carbon dioxide tracer that is quantifiable and distinguishable versus non-anthropogenic produced carbon dioxide; providing carbon dioxide to be stored in the geologic formation; determining what portion of the carbon dioxide is anthropogenic produced carbon dioxide; and mixing a predetermined quantity of the carbon dioxide tracer with the carbon dioxide stored to develop a tagged quantity of carbon dioxide for storage in the geologic formation. In some embodiments, a system for tagging a stream of carbon dioxide includes a tagging module and a mixing module. Tagging module includes a carbon dioxide tracer that is quantifiable and distinguishable versus non-anthropogenic produced carbon dioxide. Mixing module includes mechanisms for containing and injecting the carbon dioxide tracer into a stream of carbon dioxide.
