<h2><strong>Introduction</strong></h2>
<p><span style="font-weight: 400;">The global community faces an urgent imperative to combat climate change and reduce greenhouse gas emissions. In the pursuit of innovative solutions, direct air carbon capture and usage (DACCU) has emerged as a promising approach. Unlike traditional direct air carbon capture and storage (DACCS) methods that solely capture carbon dioxide (CO2) from the atmosphere, DACCU takes the concept further by utilizing the captured CO2 for beneficial purposes. </span></p>
<p><span style="font-weight: 400;">This groundbreaking technology not only contributes to reducing greenhouse gas emissions but also fosters the development of a circular carbon economy. In this article, we will delve into the concept of DACCU, explore its diverse applications, discuss its potential benefits, and shed light on ongoing research projects that showcase its viability.&nbsp;</span></p>
<h2><strong>Capturing carbon for a purpose&nbsp;</strong></h2>
<p><span style="font-weight: 400;">DACCU sets itself apart from conventional DACCS methods by transforming captured carbon dioxide into valuable resources. Rather than simply storing CO2, DACCU aims to harness its potential for beneficial utilization, thereby contributing to the reduction of greenhouse gas emissions. This approach offers an alternative to carbon-intensive practices and opens up new possibilities for sustainability.&nbsp;</span></p>
<p><span style="font-weight: 400;">To better understand how this system works, it is essential to explore its fundamental principle. This cutting-edge technology involves the direct capture of CO2 from the atmosphere, followed by its utilization as a feedstock for various applications. Specialized air capture devices, equipped with sorbents or membranes, are employed to selectively capture CO2 molecules from the ambient air. The captured CO2 is then subjected to a purification process to eliminate impurities and obtain high-purity CO2 streams suitable for utilization. Through advanced conversion techniques, such as catalytic processes or electrochemical reactions, the purified CO2 can be into a productive value chain. Thus, DACCU enables a net reduction in CO2 emissions.&nbsp;</span></p>
<p><span style="font-weight: 400;">To understand this, it is crucial to consider the concept of CO2 equivalence. When CO2 is used for the production of fuels or chemicals, it displaces the need for conventional fossil fuel sources that would have otherwise been required to produce these same products. By utilizing captured CO2 instead of other fossil carbon sources, net CO2 emissions are reduced since the captured CO2 is already present in the atmosphere and does not introduce additional carbon from underground reserves.&nbsp;</span></p>
<h2><strong>Applications of captured carbon dioxide&nbsp;</strong></h2>
<p><span style="font-weight: 400;">The versatility of captured carbon dioxide enables its application in various sectors, unlocking a range of innovative opportunities. One notable avenue is the production of synthetic fuels, wherein CO2 is combined with hydrogen to create a clean energy source. This approach reduces reliance on fossil fuels and offers a sustainable solution for energy needs.This dual benefit enhances both energy production and carbon sequestration. Moreover, DACCU has the potential to facilitate the production of carbon-negative materials, providing alternatives to carbon-intensive construction materials like concrete. By utilizing captured CO2 in this manner, DACCU contributes to a more sustainable and climate-conscious industrial sector.&nbsp;</span></p>
<h3><strong>Environmental, economic, and social benefits</strong></h3>
<p><span style="font-weight: 400;">The implementation of DACCU can yield significant environmental, economic, and social benefits.
