(i) materials, (ii) process design, (iii) equipment, (iv) system integration, and (v) infrastructure priority initiatives. Note that the first four categories need to be delivered largely by in addition to these initiatives, it is imperative DAC deployment (the construction of commercial plants) continues, to close the feedback loop with technology R&D (the blue/white shaded continued R&D in Figure ) needed to deliver further technology improvement. This deployment ramp up is depicted in Figure We suggest four main initiatives aimed at overcoming obstacles related to CO 2 capture materials: (i) exploration of the material space and identification of optimal materials (#1), (ii) exploration of material benefits (#2), (iii) assurance of stability and recyclability (#3), and (iv) independent validation of performance data (#4).
