As outlined by ExxonMobil: "Scientists at ExxonMobil and FuelCell Energy, Inc. are jointly pursuing new technology that could reduce the costs associated with current CCS processes by increasing the amount of electricity a power plant produces while simultaneously delivering significant reductions in carbon dioxide emissions.
Laboratory tests have indicated that applying carbonate fuel cells to natural gas power generation could capture carbon dioxide more efficiently than current, conventional CCS technology. In fact, our research indicates that by applying this new technology, more than 90 percent of a natural gas power plant's carbon dioxide emissions could be captured."
