| description | <p dir="ltr">This article presents a thorough life cycle assessment (LCA) study on carbon capture and utilization (CCU) systems for low‐carbon fuel production. The process involves capturing carbon dioxide (CO<sub>2</sub>) from indoor environments using an integrated heating, ventilation, and air conditioning (HVAC)—direct air capture (DAC) unit, a technology crucial for mitigating climate change (CC). Integrating DAC with HVAC systems is highlighted for its potential to enhance energy efficiency and indoor air quality. Electrochemical reduction of CO<sub>2</sub> to formic acid (FA) and Fischer–Tropsch processes are studied for carbon utilization. A sensitivity analysis was performed on the adsorbent type, electricity source, and water source. The environmental impacts were found to be 1.80 kg CO<sub>2 </sub>eq, 9.04 × 10<sup>−4</sup> kg PM2.5 eq, 1.04 × 10<sup>−5</sup> kg P eq, 2.95 × 10<sup>−3</sup> kg SO<sub>2</sub> eq, 0.36 kg 1,4 DB eq. for CC, fine particulate matter, freshwater eutrophication, terrestrial acidification, and terrestrial ecotoxicity, respectively, per kg FA produced. Using renewable energy can significantly lower the environmental impacts; the lowest value was obtained from integration with nuclear energy at 0.496 kg CO<sub>2</sub> eq/kg FA. A specific Qatar case study was also performed for FA production with CO<sub>2</sub> utilized from DAC‐HVAC. The paper highlights the environmental benefits of CCU, emphasizing its dual purpose of addressing CC and sustainable fuel production. This study represents a significant contribution to global initiatives for a more sustainable and carbon‐neutral future.</p><h2 dir="ltr">Other Information</h2><p dir="ltr">Published in: Energy Science & Engineering<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1002/ese3.70122" target="_blank">https://dx.doi.org/10.1002/ese3.70122</a></p> |
