The concluding remarks emphasized the knowledge gaps, related deficiencies, and strengths, with significant viewpoints and concepts for enhancing graphene-based MOFs for CO<sub>2</sub>RR in accordance with pragmatic industry expectations. This study offers the scientific community a thorough insight into the present research emphasis and the significance of creating more efficient and environmentally sustainable graphene-based MOFs for clean energy conversion.

In addition, negative emissions by permanently removing carbon dioxide from the atmosphere are required. Both targets require substantial amounts of carbon neutral electricity and heat production. While electricity can be produced and transferred over long distances, the heat production needs to be local. This study investigates an energy system integrating both carbon neutral heat production and carbon dioxide removal from the atmosphere. The system is modelled using the Backbone energy system modelling framework. The carbon neutral heat production in the study is based on small modular nuclear reactors (SMRs), large-scale thermal energy storages (TES), heat pumps (HPs) and electric boilers (EBs), and the carbon removal is implemented by direct air capture (DAC) combined with permanent geological storage. The studied technologies are integrated into a specific large-scale district heating system located in Northern Europe. The impact of outdoor temperature for the efficiency of the DAC process is considered, and the system integration potential with the district heating system is evaluated. The results show that high 70–90 % utilisation rates for both SMR and DAC units can be reached but depending on the case year and corresponding profiles for demand, outdoor temperature, electricity and carbon prices, a large variation in utilisation rates is observed. The variable CO<sub>2</sub> capture costs were between 115–126 €/t CO<sub>2</sub> in the modelled scenarios, and with higher OPEX values at the range 152–163€/tCO<sub>2</sub>, and the limit price for economic viability considering the investment was calculated to be in the range of 209–223 €/tCO<sub>2,</sub> with lower, and 233–246 €/tCO<sub>2</sub> with higher adsorbent costs.

This study presents an innovative strategy for waste valorization by repurposing three modified AOD slag variants (raw, aged, and carbonated) as nutrient supplements for <em>Chlorella pyrenoidosa</em> cultivation. Moreover, process parameters in microalgae cultivation, such as algal characteristics and complex operational conditions, will affect its yield and productivity. Traditional methods struggle to enable comprehensive understanding and application. Thus, quantitative prediction was conducted using 96 sets of total CO<sub>2</sub> carbon sequestration data (80% for the training set and 20% for the test set). Combined with three machine learning models and the Shapley Additive explanation (SHAP) algorithm, the intrinsic mechanisms by which five leaching elements (Ca, Mg, Al, Si, and Cr) regulate the efficient carbon sequestration of microalgae were analyzed. Notably, the random forest model excelled well in predicting CO<sub>2</sub> storage and elemental leaching, with performance metrics exceeding 0.87.

In response to the identified research gap, this work examines projections for CO<sub>2</sub> capture deployment within the EU industrial sectors, focusing on the cement, iron and steel, and chemical industries, for 2030 and 2050. We harmonize and discuss sectoral projections from seventeen scenarios, and in order to draw cross-sectoral conclusions, we compare them with 820 aggregated, EU-wide industry scenarios. The sectoral projections mapped project carbon capture to significantly reduce emissions in the cement sector by an average of 70 % by 2050. In the near term, projections for 2030 show the highest emission reductions in the chemical sector (10 %), followed by cement (7 %) and iron and steel (5 %). Sectoral projections align well with EU-wide scenarios, particularly with those complying with global 2 °C targets. Notably, many scenarios exceed the Net-Zero Industry Act target for 2030 and project capture levels beyond historical uptake trends of clean energy technologies. The findings highlight that while long-term projections consistently foresee large-scale deployment of CO₂ capture across EU industry, near-term expectations remain modest and risk falling short of the 2030 needs.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"17 ","pages":"Article 100528"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145262792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
