摘要

The gap between an energy sector that relies on fossil fuels and one that relies on renewable resources may be bridged by systems that conserve resources, use closed-looped processes, and reduce carbon dioxide (CO_2) emissions. CO_2 capture and storage (CCS) technology may reduce CO_2 emissions by injecting CO_2 captured from power plants into deep saline aquifers for sequestration, but these systems have additional water and energy requirements that may impede deployment due to regional water stress and increased energy costs. CO_2 capture, utilization, and storage (CCUS) operations that use Active CO_2 Reservoir Management (ACRM) can manage pressure and provide additional CO_2 storage capacity by producing brine from reservoirs through enhanced water recovery (CO_2-EWR) . Produced brine can be treated by desalination for beneficial use and provide a source of water that could partially or fully offset water requirements by facilitating a closed-loop water source for CCUS with the potential to produce additional water for power plant cooling or other societal needs. Further, the energy of this pressurized brine can be used during the reverse osmosis process to substantially reduce the treatment costs and make CO_2-EWR a feasible CO_2 emission reduction technology.
