Innovative Solutions: Direct Air Capture for Combating Climate Change and Achieving Carbon Neutrality

In the global fight against climate change, innovative technologies are being considered to capture carbon dioxide directly from the atmosphere. One such technology, known as direct air capture (DAC), involves building large structures with arrays of huge fans that suck in air to capture carbon dioxide before releasing carbon-free air back into the atmosphere.

Despite being in its early stages, DAC is seen as a powerful tool to prevent catastrophic climate change. Professor Mihri Ozkan from UC Riverside will be representing the United States at a U.N. meeting on carbon capture, storage, and utilization in Vienna, Austria. The meeting aims to assess the potential rollout of DAC technologies for a carbon-neutral future.

Ozkan emphasizes the importance of coupling DAC with renewable energy sources to reduce its high energy use. Advancements in material science and process engineering are also needed to make DAC facilities more efficient in capturing carbon dioxide. Ozkan further highlights the importance of converting captured carbon dioxide into valuable byproducts used by industry.

Government policies, such as carbon and tax credits, are also essential to reduce costs and spur investments in DAC technology. Ozkan’s recommendations will be detailed in her upcoming paper, “Atmospheric Alchemy: The Energy and Cost Dynamics of Direct Air Carbon Capture,” to be published in the journal MRS Energy & Sustainability.

As the world comes together to address the challenges of climate change, technologies like DAC offer hope for a sustainable future. With continued research and innovation, combating climate change through carbon capture may soon become a reality.
