Decarbonization targets for the maritime sector until 2050 require greenhouse gas (GHG) mitigation options like alternative fuels and on-board carbon capture (OCC). This study assesses GHG mitigation and side-effects of OCC via Life Cycle Assessment of two LNG-fueled ships, the large crane ship Sleipnir and an LNG carrier, and their distinct operational profiles. A large bandwidth of 32%–55% GHG …

This study investigates spurrite (Ca 5 (SiO 4 ) 2 CO 3 ) formation under CO 2 -rich atmospheres relevant to oxyfuel combustion in cement kilns. Synthetic raw meals doped with 1.0–3.0 wt.% chloride were thermally treated at 800, 850, and 900 °C under air, 63 vol.% CO 2 , oxyfuel 1st gen., and pure oxyfuel conditions. Phase assemblages were analyzed by X-ray diffraction with Rietveld refinement and…

• The technical viability of adsorption-based CO 2 capture has been demonstrated. • A traceable list of 40 pilot-scale CO₂ capture demonstration projects worldwide. • Fewer than 15 different adsorbent types are employed in pilot-scale projects. • Limited knowledge on CO 2 capture processes in the presence of impurities. • Cost sensitivity analyses are largely absent from the literature. Adsorptio…

• High-spatial-resolution analysis of downslope variability in seal capacity. • Lowest and slight basinward increase in seal capacity in the outer shelf deposits. • Significant increase from the shelf margin to the base of the slope deposits. • Highest and nearly constant seal capacity in the basin floor deposits. • The findings can be a useful geological analog to aid seal risk assessment. The l…

• The CO 2 storage component of DACCS is less desired than the capture. • Benefit perception and feelings of tampering with nature are the strongest drivers of DACCS acceptance. • Government and the industry are the least trusted actors; science and NGOs the most trusted. • DACCS is still largely unfamiliar to the public. • Exposure to information decreases acceptance. Direct Air Capture and Stor…
