Models deployment scenarios with realistic capacity factors and supply-chain constraints.

Carbon capture more costly than switching to renewables, researchers find — Stanford/UC Berkeley study comparing system-level costs: renewables + storage + transmission achieves 90%+ grid decarbonization at lower $/ton CO2 avoided than fossil + CCS.

Implementation Guides

So you want to build a carbon capture company — Casey Handmer (former JPL, Hyperloop One) provides a rigorous engineering analysis of direct air capture (DAC) economics and thermodynamics. Covers minimum energy requirements (thermodynamic limit ~130 kWh/ton CO2), sorbent chemistry tradeoffs, contactor design, capital cost scaling, and why most DAC startups fail on unit economics — essential reading before entering the space.

Today’s Synthesis

Casey Handmer’s DAC reality check lays out the thermodynamic and economic guardrails: regeneration energy must approach the ~130 kWh/ton theoretical minimum, sorbent cycle life needs thousands of swings, and contactor capital cost scales with air throughput. The Georgia Tech/Meta open dataset gives you the training data to build ML surrogates that predict CO₂ capacity, selectivity, and regeneration energy across thousands of MOFs and amine-functionalized polymers — exactly the properties Handmer identifies as make-or-break. The Helsinki solid amine sorbent (>90% capture at 400 ppm, lower regeneration temperature) serves as a validation benchmark: can your model rediscover its design principles? An engineer could spend a weekend fine-tuning a graph neural network on this dataset, constrained by Handmer’s cost model, to generate a ranked shortlist of synthesizable candidates worth testing in a lab — turning material discovery from intuition-driven to a constrained optimization problem with measurable economic targets.
