Oxygen transport membranes (OTM) are devices which allow efficient separation of O2 from air without the energy penalties associated with the currently-popular method of cryogenic separation. Pure oxygen has a number of uses and the most relevant one here is oxy-fuel combustion, where it is used in place of air for the burning of fossil fuels in a power plant. The resulting flue gas requires very little processing before it consists solely of carbon dioxide, which can be sequestered for a carbon-neutral electricity generation process. Zac’s research is focused on the production of small-scale OTM cells, design and construction of a test rig and development of a rapid test methodology in order to screen new cell chemistries quickly at minimum cost.
