Despite significant research into the scale and potential of this technology, there remains a lack of techno-economic analyses (TEAs) that comprehensively capture the full-process costs of indirect carbonation using a pH-swing approach. This approach enables both CO<small>₂</small> storage in carbonates, potentially usable to decarbonize concrete, and the extraction of critical minerals, incorporating the costs and revenues of coupling these processes. To address this gap, we developed a Class IV TEA tailored to estimate the costs and life cycle assessment (LCA) of combining critical mineral extraction and carbon mineralization in mining wastes. The model evaluates scenarios for various waste types (<em>i.e.</em>., legacy asbestos waste, aggregate quarry tailings, platinum group metal tailings) under different extraction conditions (acid type, temperature, strength) and carbonation parameters. Additionally, sensitivity analyses explore the effects of reactor design, internal acid–base recycling, and other factors on process costs and carbon efficiency. Our findings show carbon efficiencies of up to 95%, depending on process design. Acid–base recycling is critical for cost-effective and carbon-negative operations: without recycling, process costs exceed $3000 per tCO<small>₂</small> and yield a carbon efficiency of −280%, while internal acid regeneration reduces costs to $500–800 per tCO<small>₂</small> with carbon efficiencies ranging from 41–72%. Process costs vary by waste type and process conditions, ranging from $800–1800 per tCO<small>₂</small> (assuming 10% reagent makeup), with the carbonate precipitation step contributing 34–78% of total costs. The TEA highlights that acid–base recycling is essential for scaling the pH-swing process on mine tailings and should be a research priority to enable gigatonne-scale CO<small>₂</small> storage by mid-century. Additionally, selectively recovering critical minerals in wastes where magnesium and calcium are not exclusively leached could significantly offset capital costs.</p>","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":" 3","pages":" 435-446"},"PeriodicalIF":3.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ya/d4ya00567h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The push towards terawatt-scale PV manufacturing means it is increasingly desirable to develop indium-free TCOs to facilitate the upscaled manufacturing of high-efficiency cell designs. Aluminium-doped ZnO (AZO) deposited by atomic layer deposition (ALD) has emerged as a promising candidate due to its combination of optical transparency and electrical conductivity. In addition, AZO has also been shown to passivate the c-Si surface. The ability for one material to provide all three properties without requiring any indium is advantageous in single junction and tandem solar devices. Herein, we demonstrate exceptional silicon surface passivation using AZO/AlO<small>_<em>x</em></small> stacks deposited with ALD, with a <em>J</em><small>₀</small> &lt; 1 fA cm<small>⁻²</small> and corresponding implied open circuit voltage (iV<small>_OC</small>) of 740 mV. We provide a comprehensive analysis of the role of ALD precursor dosing to achieve optimised performance. A broad range of characterisation approaches were used to probe the structural, compositional, and chemical properties of AZO films. These indicated that the passivation properties are governed by a delicate interplay between the Zn and Al concentrations in the film, highlighting the importance of precise process control. Optical modelling in a single junction SHJ architecture indicates these AZO films are close in performance to high-mobility indium-containing TCOs. The insights provided by this work may help to further the case of indium-free TCOs, which is critical for upscaled production of high-efficiency solar cells.</p>","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":" 4","pages":" 553-564"},"PeriodicalIF":3.2,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11826515/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143434418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmission electron microscopy revealed that ZnO was in the form of nanoparticles due to the inert surface properties of graphite and only a few cycles of ALD. Electrochemical characterization demonstrated that the ZnO ALD nanoparticles significantly inhibited dendrite growth, and X-ray photoelectron spectroscopy revealed that side reactions at the electrolyte–electrode interface were inhibited with the deposition of ZnO. The SEI layer was stabilized, which improved the cycling stability of the ZnO–graphite composite electrode.
