Abstract

Purpose of Review This review aims to summarize the different energy sources that have been proposed to power direct air capture (DAC) of CO2, to assess their maturity and to suggest overlooked concepts.

Recent Findings Among the concepts based on renewable energy, the authors found that concentrated solar thermal (CST) technologies have been largely overlooked, even though they are the most cost-effective source of renewable dispatchable heat.
