Carbon Capture Powered by Solar Energy
ANZSRC / FoR Code
03 CHEMICAL SCIENCES
The urgent implementation of emissions control measures is inhibited in part by the expense of carbon capture technology. A large part of the cost of amine based approaches is in the heat regeneration of the absorbent. An alternative way to do this could be through use of abundant solar energy. In a new approach, direct chemical action on the absorbed CO2 was achieved by use of a reversible photoacid. Irradiation of the CO2 loaded solution resulted in CO2 removal by action of light.
