*'''[[Accelerated Science|Accelerated materials discovery]]''' '''of new chemical sorbents:''' One potentially promising ML application for DAC is accelerated materials discovery of new chemical sorbents that either bind to atmospheric CO<sub>2</sub> with either greater selectivity or have lower energy input requirements.

*'''[[CO2 Migration Modeling|CO<sub>2</sub> migration modeling]]:''' For carbon capture and sequestration to be effective, it must sequester CO<sub>2</sub> for hundreds or thousands of years. Thus, understanding the long-term migration of sequestered CO<sub>2</sub>, particularly in underground saline reservoir formations but also in basalts, is of critical importance. Machine learning can help speed up computationally intensive reservoir simulation models by orders of magnitude, accelerating the speed at which scientists can answer key questions.
