Designer Nitrogen-Linked Carbons Cut CO2 Capture Energy Costs

Chiba University researchers developed viciazites—carbon materials with adjacent, controllably arranged nitrogen groups—that enable CO2 capture and desorption at much lower temperatures (desorption below 60 °C), potentially using industrial waste heat to cut operating costs. Different adjacent nitrogen configurations showed varying performance: adjacent –NH2 and pyrrolic nitrogen improved CO2 uptake, while adjacent pyridinic nitrogen offered less benefit. This work provides a design framework for cheaper, next‑generation carbon capture materials and could have broader uses beyond CO2 removal.

Summit Pipeline Pivot: CO2 Moves From Carbon Capture to Oil Recovery Amid Permitting Battles

Summit Carbon Solutions has pivoted its Midwest CO2 pipeline from underground storage to supplying CO2 for enhanced oil recovery (EOR), aiming to boost oil production in basins like Powder River, Bakken, and Permian. The shift comes amid ongoing eminent-domain battles and permit challenges in Iowa and surrounding states, and after federal tax credits began rewarding CO2 used for EOR as well as storage, prompting Summit to adjust its messaging away from climate terms.

Seawater and CO2 turn into carbon-storing cement ingredients

Researchers show that seawater and carbon dioxide can be converted in a tabletop reactor into solid minerals (calcium carbonate and a magnesium-rich solid) that can form powders or grains, potentially replacing mined sand in concrete and, in some mixes, store more CO2 than the process emits (carbon-negative). If powered by clean energy and scaled up, near‑shore modular reactors could sequester CO2 at the source and reduce cement's climate impact, though durability and wear tests at larger scales are still needed.

Three-Layer Electrode Bridges CO2 Capture and Conversion to Formic Acid

A three-layer gas-diffusion electrode can simultaneously capture CO2 from real-world gas streams (including dilute ambient air and simulated flue gas) and convert it directly into formic acid, outperforming existing electrodes under realistic conditions. The device combines a CO2-selective capture layer, a gas-permeable carbon paper, and a tin(IV) oxide catalyst, offering a simpler, on-site route to carbon utilization with potential adaptation to other greenhouse gases in the future.
