Large scale deployment of Direct Air Capture (DAC) will lead to significant demand for heat and electricity. Supplying heat and electricity can result in significant emissions, if served by carbon intensive sources of energy. This is a particular concern because DAC is capital intensive and likely to be run at close to maximum output. This makes it challenging for DAC plants to be powered solely by cheap, intermittent, clean sources of power such as wind and solar. In this work, the authors undertake an interdisciplinary study combining process engineering with a detailed macro-energy system optimization model to evaluate the site and system-level costs of combining high temperature thermal energy storage (TES) with DAC.
