With prices soaring and domestic reserves depleting, natural gas is no longer the inexpensive, clean alternative for the utilities. The one reliable and inexpensive utility fuel in the near term is coal. As attention swings back into coalís favor, the need to solve the emissions problem is heightened. The Department of Energy and industry have numerous technology initiatives for clean energy from coal. The most significant of these, the FutureGen project, aims to mitigate the environmental affects by advancing technological solutions such as carbon capture. While some of the details of FutureGen are changing, the project will still revolve around Integrated Gasification Combined Cycle (IGCC) systems and greater attention will be applied to Carbon Capture and Storage (CCS). Adoption of CCS technologies will be dependent upon government regulation and demonstrated process economics. Eltron Research & Development Inc. is developing the most economical solution to carbon capture in IGCC power plants. Eltron is developing a membrane system that separates hydrogen from carbon dioxide, enabling clean power generation and carbon sequestration in IGCC systems. Eltronís Membrane System enables economical and clean power generation from coal by providing improved carbon capture, greater efficiencies and an incremental cost reduction over conventional technologies. Membrane data collected under expected operating conditions as well as comparative techno-economic modeling results will be presented. Modeling demonstrates that a process containing Eltronís Membrane System is economic in multiple configurations. Models show up to $11/MWh cost of electricity savings over current technology and 6% higher HHV efficiencies while capturing up to 95% CO2.
