Efficient CO2 Utilization via a Hybrid Na-CO2 System Based on CO2 Dissolution - ScienceDirect
Converts CO2 to hydrogen and baking soda via electrolytic cell and aqueous solution. Dependent on the aqueous solution though, where does that come from, how hard is it to regenerate, etc. Makes power too

Low cost plasma membrane reactor to efficiently convert ammonia to hydrogen
Using a plasma field between an iron tube and palladium foil tube, ammonia can be broken down to nitrogen and hydrogen, with the hydrogen pulled through the palladium foil efficiently, resulting in very high hydrogen gas purity separation. Process is low temperature and pressure as well, though the palladium foil probably isn't cheap. Effectively an ammonia fuel reformer for a hydrogen fuel cell, allowing storage of low pressure ammonia as fuel.

Oxygen-separation membranes could aid in CO2 reduction - MIT News Office
Interesting possible combustor design for oxyfuel plants, where a combustor wrapped in this ceramic membrane does heat accelerated oxygen ion transport across the membrane from the air side to the combustor interior. How useful this is for regular oxygen separation is up for debate though, since this seems to want a direct heat source which would be difficult to arrange for a traditional ASU, thus pushing you to cryogenic air separation techniques. Hrm, I wonder if the flow rates and weight would be attractive to aircraft jet engine combustor applications, maybe extending up into a competitor for LACE?

A different carbon capture setup, sending slightly pressurized exhaust gas through a supersonic cyclonic separator that freezes the CO2 and water out of the exhaust. Also claims 50% reduction in parasitic load. Basically the same as a twister setup for natural gas cleaning.

Sustainable Energy Solutions
Hrm, these guys are proposing cryogenic separation of CO2 in exhaust gases. Which could be energy intensive even with heat recovery, but they are claiming up to 50% less parasitic load compared to other methods. With such a large N2 or LN2 volume you could operate as a LN2 producer as well (which could couple into an ASU for LOx production). Proposed as an easy retrofit to existing air input thermal powerplants (gas turbine/coal). Because if you were doing this new, it would be easier to go IGCC/oxyfuel coal/gas turbine to isolate CO2 by simple water condensing the exhaust.
