the Zero Emissions Research and Technology Center (ZERT) has been created with the mission of conducting basic and applied research that support the development of new technologies for minimizing emissions of anthropogenic carbon dioxide and other greenhouse gases that impact global climate change. Department of Energy (DOE), through the National Environmental Technology Laboratory (NETL) has requested the development of numerical simulation capabilities for quantifying the permanent storage capacity, leakage rates, and public risks associated with geologic sequestration of CO2. Instead, scientists, engineers, regulators, and ultimately more » the public will rely on numerical simulations to predict the performance of geologic repositories for carbon dioxide sequestration. Monitored field-scale demonstrations of geologic sequestration of carbon dioxide will contribute greatly toward growing trust and confidence in the technology however, pilot demonstrations ultimately will not be the norm for new geological sequestration deployments. Demonstrating that geologic sequestration of CO2 is safe and effective, and gaining public acceptance of sequestration technologies are critically important in meeting these global climate change challenges. Geologic sequestration is currently being practiced and scientifically evaluated as a critical component in a broad strategy, comprising new practices and technologies, for mitigating global climate change due to anthropogenic emissions of CO2. Therefore, the development of highly selective and permeable membranes for the separation and ultimate sequestration of CO2 is of vital = , As an alternate CO2 capture technology, polymer-based membrane separations offer relatively low operating costs with low-maintenance requirements.
The initial step toward this technology is to identify and develop an economically viable method of separating CO2 from flue gas at large point sources such as coal-fired power plants. This separation and sequestration technology is also likely to play a role in maintaining the economic value of fossil fuels in the event of a concerted global CO2 mitigation effort. Therefore, as climate change becomes an increasingly unavoidable environmental, industrial, and political issue, it is desirable to develop technology capable of economically separating and sequestering large amounts of CO2. Carbon dioxide (CO2) makes up 78% of anthropogenic greenhouse gas production and has been linked to global climate change and ocean acidification.
