Oct 31, 2019The idea is to pass a stream of flue gas or air through the device during charging to scrub it of carbon dioxide from. Once the electrode is saturated, the device would be switched to discharge mode and the pure released carbon dioxide could be compressed for storage underground or for use to make fuels and other chemicals.

    SF 6 Free Gas Handling Alternatives to SF 6. The so-called Alternative Gases are alternatives to SF 6, the preferred insulating and arc-quenching gas used in switchgear in the last few decades.While SF 6 has excellent dielectric properties, it is also the most potent greenhouse gas with a GWP of 23,900. Ideally, SF 6 should be used in closed loop systems and never be emitted into the atmosphere.

    Aug 23, 2010SF6 is on the list of greenhouse gases in the Kyoto Protocol (1). SF6 is the most potent of the six main greenhouse gases, with a GWP of 23,000 (5). The United Nations institution that monitors this, the Intergovernmental Panel on Climate Change (IPCC), has since added SF6 gas to the list of extremely harmful greenhouse gases.

If the sinks are tolerant to NO x and SO 2, we can eliminate separate control steps and sequester the NO x and SO 2 along with the CO 2, resulting in a zero emissions power plant.
