Climate change mitigation requires the large-scale deployment of carbon capture and storage (CCS). Recent plans indicate an eight-fold increase in CCS capacity by 2030, yet feasibility expansion is debated. Using historical growth other policy-driven technologies, we show that if double between 2023 2025 their failure rates decrease half, could reach 0.37 GtCO

Limiting the rise in global temperature to 1.5 °C will rely, part, on technologies remove CO 2 from atmosphere. However, many carbon dioxide removal (CDR) are early stages of development, and there is limited data inform predictions their future adoption. Here, we present an approach model adoption early-stage such as CDR apply it direct air capture storage (DACCS). Our combines empirical historical technology analogs indicators a range feasible growth pathways. We use these pathways inputs integrated assessment (the Global Change Analysis Model, GCAM) evaluate effects under emissions policy limit end-of-century change °C. Adoption varies widely across analogs, which share different strategic similarities with DACCS. If DACCS mirrors high-growth (e.g., solar photovoltaics), can reach up 4.9 GtCO by midcentury, compared low 0.2 for low-growth natural gas pipelines).

CO2 hydrates hold promising applications, including as a medium for carbon storage in oceanic sediments, result of their high capacity. However, the presence salinity sediments is likely to affect hydrate kinetics. To counter this challenge, formation, dissociation, and deep morphology have been investigated seawater (SW) under static non-static conditions.

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

Abstract Approximately 20% of global CO 2 emissions originate from sectors often labeled as hard-to-abate, which are challenging or impossible to electrify. Alternative abatement options necessary for these but face critical bottlenecks, particularly concerning the availability and cost low-emission hydrogen, carbon capture storage, non-fossil synthetic fuels carbon-dioxide removal. In this study, we conduct a broad techno-economic analysis, mapping hard-to-electrify while addressing associated technological uncertainties. Our findings reveal diverse mitigation landscape that can be categorized into three tiers, based on technologies required. By requiring long-term climate neutrality through simple conditions, narrows substantially, with single dominating each sector. This clarity justifies targeted political support sector-specific options, increasing investment security transforming sectors.
