Electrochemical DAC regains attention with breakthroughs
Key Questions
What recent breakthroughs are boosting electrochemical DAC?
Advancements include ASU's IRA-900 (100k cycles, low-energy), NW MnO2 (4.1 GJ/t), and Avnos HDAC (low-water, humidity amines/hot water). These regain attention for efficiency gains. Pilots, cycles, and MRV are needed for scaling.
How do new electrochemical DAC technologies compare?
ASU achieves 100k cycles with low energy via IRA-900; NW MnO2 at 4.1 GJ/t; Avnos uses low-water HDAC with humidity amines and hot water. Benchmarks against Yama emphasize tactical pilots and MRV. Status remains developing.
What challenges remain for electrochemical DAC despite breakthroughs?
While energy-efficient and low-water innovations like ASU, NW MnO2, and Avnos advance the field, pilots, cycle testing, and MRV are essential for viability. Comparison to benchmarks like Yama is key. Broader CCUS initiatives support momentum.
