Producing carbon dioxide with waste heat

A system, comprising:

• a power plant that comprises outputs comprising a thermal energy output and an electrical power output;
• an industrial process that is electrically coupled to the electrical power output of the power plant and that comprises a source of heat thermally coupled to a heating fluid to transfer heat from the source of heat to the heating fluid;
• and
• a direct air capture (DAC) system electrically coupled to the electrical power output of the power plant, the DAC system comprising:
• an ambient airflow input through which ambient air enters the DAC system,
• a carbon dioxide output, and
• a carbon dioxide source material comprising an adsorbent to which carbon dioxide from the ambient air bonds,
• wherein the carbon dioxide source material is arranged to receive heat from at least one of the heating fluid or the thermal energy output of the power plant, and
• wherein, when heated, adsorbed carbon dioxide is separated from the carbon dioxide source material and provided as a carbon dioxide supply stream to the carbon dioxide output.
