Berkeley’s Magic Material: Capturing Carbon From the Air Just Got Easier
Article by Najah Al Riyami, published in Oman Daily Observer on December 30, 2024
Oman is advancing the global decarbonization effort with Direct Air Capture (DAC) technology, which extracts CO₂ from the atmosphere. Despite being energy-intensive, DAC is crucial for achieving net-zero emissions. Omani startup 44.01 is leading a project to capture CO₂ through carbon mineralization in the Hajar Mountains, while Occidental Petroleum plans similar initiatives in Oman. With 27 DAC plants worldwide and more under development, DAC is set to play a key role in meeting climate goals.

Accelerated Testing of PEI-Silica Sorbent Pellets for Direct Air Capture
Harshul V. Thakkar, Andrew J. Ruba, John A. Matteson, Michael P. Dugas, and Rajinder P. SinghACS Omega 2024 9 (46), 45970-45982DOI: 10.1021/acsomega.4c05639
This study evaluates the degradation of polyethylenimine (PEI) sorbents for Direct Air Capture (DAC) of CO2, focusing on their stability in different environments. It introduces a novel, solvent-minimized synthesis method that reduces toxic solvent use by 94%. Results show that PEI sorbents degrade rapidly at high temperatures and in ambient air, with degradation exacerbated by dry CO2. Accelerated testing reveals greater degradation in dry CO2 environments compared to wet CO2 and inert conditions.

Will Direct Air Capture Ever Cost Less Than $100 Per Ton Of CO₂?
Article by Phil de Luna, published in Forbes
Direct Air Capture (DAC) is a promising tool for combating climate change, but the widely cited $100 per ton CO₂ target is increasingly unrealistic due to inflation and technical challenges, with current costs closer to $500–$1,000 per ton. Instead of fixating on this goal, experts suggest using the social cost of carbon—$185–$266 per ton—as a more meaningful benchmark, as it reflects the economic damages of emissions. While DAC costs remain high, scaling the technology and aligning it with climate policies can still deliver significant benefits in mitigating future climate impacts.

Coupling PV with direct air capture
Article by Emiiano Bellini, published at Pv-Magazine
Researchers from Shanghai Jiao Tong University propose coupling photovoltaic (PV) power plants with direct air capture (DAC) systems to reduce solar power curtailment and enhance DAC’s economic viability. Their study highlights that flexible DAC systems, which can dynamically adjust operations based on power availability, are more cost-effective than using battery energy storage. By utilizing excess solar power, DAC could address curtailment issues while lowering operational costs. The researchers predict this combination could become feasible by 2030, driven by rising carbon prices and decreasing costs of adsorbents.
