 - Highlights in Energy Research seminar series\nWorldwide energy demand is
  projected to grow strongly in the coming decades\, with most of the growt
 h in developing countries.  Even with unprecedented growth rates in the d
 evelopment of renewable energy technologies such as solar\, wind and bioen
 ergy\, the world will continue to rely on fossil fuels as the predominant 
 energy source for at least the next several decades.  Simultaneously\, du
 e to decades of inaction\, most current climate models suggest that limiti
 ng warming to <2°C will require large scale deployment of negative emissi
 ons technologies (NETs).  NETs\, which remove CO2 from the atmosphere\, a
 re projected to be needed at a scale of 10 Gt/y by 2050\, yet today\, virt
 ually none of been deployed.1 NETs may be natural or technological\, with 
 one of the most scalable technological approaches being the direct capture
  of CO2 from the air\, or “direct air capture” (DAC).2 Because of the 
 ultra-dilute nature of air\, the separation of CO2 from this mixture prese
 nts a significant engineering challenge.\n\nIn this lecture\, I will descr
 ibe the design and synthesis\, characterization and application of new sup
 ported amine materials that we have developed as cornerstones of new techn
 ologies for the removal of CO2 from dilute (flue gas) and ultra-dilute (ai
 r) gas streams.3 These chemisorbents efficiently remove CO2 from simulated
  flue gas streams\, and the CO2 capacities are actually enhanced by the pr
 esence of water\, unlike in the case of physisorbents such as zeolites.  
 We will describe the development of these materials\, how they integrate i
 nto scalable DAC technologies\, as well as their key physicochemical struc
 ture-property relationships.  DAC technologies offer an interesting case 
 study for the parallel design of materials\, unit operations\, and process
 es in chemical engineering.\n\n1. https://nas-sites.org/dels/studies/cdr/\
