At an absorber station, CO2 is absorbed from a gas stream into a suitable solvent whereby to convert the solvent into a CO2-enriched medium, which is conveyed to a desorber station, typically nearer to a solar energy field than to the absorber station. Working fluid, heated in the solar energy field by insolation, is employed to effect desorption of CO2 from the CO2-enriched medium, whereby to produce separate CO2 and regenerated solvent streams. The regenerated solvent stream is recycled to the absorber station. The CO2-enriched medium and/or the regenerated solvent stream may be selectively accumulated so as to respectively optimise the timing and rate of absorption and desorption of CO2 and/or to provide a storage of solar energy.
