AbstractEfficient production of hydrogen from abundant fossil fuel reserves along with effective CO2 sequestration processes can lead to reduction of greenhouse gas emissions and elimination of dependence on foreign oil. Currently, hydrogen production via water-gas shift (WGS) reaction of either a coal-derived syngas or natural gas steam reformate, coupled with pressure-swing adsorption is the most economical means for central hydrogen production. Removal of CO2 from the product side of the WGS reactor will result in significant increase in hydrogen yields. This proposal aims to fabricate and demonstrate a thick-film, high temperature CO2 separation membrane with controlled microstructure that operates electrochemically to achieve a high selectivity and is tailored for integration with a WGS reactor for hydrogen production. Commercial Applications and Other Benefits: The proposed ME-WGS technology for hydrogen production with CO2 sequestration has the potential to mitigate global climate change by reducing carbon emissions from coal fired power plants. When fully operational, this technology will help reduce our dependence on foreign energy sources, provide clean energy from fossil fuel until renewable energy technologies mature and ultimately enhance the energy and national security of our country. It will also help provide technological leadership to the US in exporting advanced energy technologies that the developing world urgently needs.
