Metal organic frameworks (MOFs) are ultraporous materials that can act as solid adsorbents for carbon dioxide. Consisting of metal atoms or clusters linked periodically by bridging organic groups, there internal pores can be tailored to act as high capacity sites for carbon dioxide capture. Furthermore, organic groups may be introduced to allow the triggered release of the captured gas, removing the need for heating during regeneration, lowering the parasitic energy demand of the technology upon the power generator.Figure 1. Solid adsorbents can store captured carbon dioxide in far greater capacity that what exists in the compressed state.This presentation will describe recent work at CSIRO that has resulted in the development of an adsorbent with a CO2capture capacity over 300% that of commercial materials, and a strategy to allow the release of captured gas by using concentrated sunlight.[1] R.
