Atmospheric CO 2 removal (CDR) is a fundamentally endergonic process. Performing CDR or Bioenergy with Carbon Capture and Storage (BECCS) at the gigatonne scale will produce significant additional burden on planet’s limited renewable energy resources irrespective of technology employed. Harnessing photosynthesis to drive industrial-scale fixation has been interest because its minimal requirements potential low costs. In this review, we evaluated thermodynamic considerations performing atmospheric carbon using microalgae cyanobacteria versus physicochemical processes explore implications these energetic costs scalability each respective solution. We review biomass productivities recently discovered fast-growing cyanobacterial strains discuss prospects genetically engineering certain metabolic pathways for channeling fixed into ‘carbon sinks’ further enhance their capture while concurrently extracting value. share our perspectives how new highly productive chassis combined advanced flux balance models, essentially coupling synthetic biology industrial biotechnology, may unlock more favorable methods CDR, both from an economic perspective.

Escalating carbon dioxide (CO2) emissions have intensified the greenhouse effect, posing a significant long-term threat to environmental sustainability. Direct air capture (DAC) has emerged as promising approach achieving net-zero future, which offers several practical advantages, such independence from specific CO2 emission sources, economic feasibility, flexible deployment, and minimal risk of leakage. The design optimization DAC sorbents are crucial for accelerating industrial adoption. Metal-organic frameworks (MOFs), with high structural order tunable pore sizes, present an ideal solution strong guest-host interactions under trace conditions. This perspective highlights recent advancements in using MOFs DAC, examines molecular-level effects water vapor on capture, reviews data-driven computational screening methods develop molecularly programmable MOF platform identifying optimal sorbents, discusses scale-up cost DAC.

Growing demand for air travel and limited scalable solutions pose significant challenges to the mitigation of aviation's climate change impact. Direct capture (DAC) may gain prominence due its versatile applications either carbon removal (direct storage, DACCS) or synthetic fuel production utilization, DACCU). Through a comprehensive time-dynamic techno-economic assessment, we explore conditions fuels from DACCU become cost-competitive with an emit-and-remove strategy based on DACCS under 2050 CO
