Table shows the results from our analysis of the three indices. Some technologies have received comparatively higher SCRI, e.g., amine-based absorption, adsorption for precombustion capture, pipeline transport, and geological CO 2 storage. On the other hand, novel technologies such as next generation absorbents, and adsorbents, dense inorganic membranes, and direct air capture, received a lower SCRI due to the fact that there is no large-scale prototype of these technologies for CCS applications. Therefore, the development of capture technology supply chains is paramount in order to deploy CCS. In addition to R&D efforts, further investment is required to encourage the establishment of production facilities and accompanying logistics.
