Here we introduce a framework that combines graph theory and topological data analysis to classify the US coal fleet into eight distinct groups based on technical, economic, environmental and socio-political characteristics. We calculate each non-retiring coal plant’s ‘contextual retirement vulnerability’ score, a metric developed to quantify susceptibility to retirement drivers using the graph-based distance to a coal plant with an announced early retirement. Separately, we identify ‘retirement archetypes’ that explain the key factors driving announced retirements within each group, which are used to inform group-specific strategies for accelerating retirements. Our findings reveal the diverse strategies that are required to accelerate the phase-out of remaining coal plants, including regulatory compliance, public health campaigns and economic incentives. The phase-out of coal will require targeted strategies. New research assesses the retirement vulnerability of coal plants in the USA based on similarity to plants with announced retirements. The findings highlight strategies to guide and accelerate phase-out.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 10","pages":"1274-1288"},"PeriodicalIF":60.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we propose solid dissociation in which halide van der Waals materials act as solid solvents to dissolve salts, forming amorphous ion-conductive solids. Using this approach, we discover 73 materials, with 40 exhibiting ionic conductivities exceeding 10−3 S cm−1, conducting Li+, Na+, Ag+ and Cu+. We analyse atomic-scale interactions between solvents and salts, uncovering dynamic structural rearrangements that enable solid dissociation. Across diverse solvent–salt pairs, consistent ionic environments emerge, revealing universal mechanisms governing ion transport in this system. Analogous to the compositional tuning of liquid electrolytes, solid dissociation allows targeted engineering of solid-state electrolytes for specific application conditions. Prototype electrolytes have been developed for fast-charging cells, low-temperature cells and 4.8-V high-voltage cells, and demonstrate enhanced dry-room stability and cost advantages. Solid dissociation offers a versatile platform for advancing next generation solid-state electrolytes. Conventional solid-state electrolyte design is limited by dopant–lattice compatibility. This work introduces solid dissociation, using halide van der Waals materials to dissolve salts and create amorphous conductors with high ionic conductivity and potential for use in devices.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 10","pages":"1237-1250"},"PeriodicalIF":60.1,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, COR energy efficiency remains below 40% due to sluggish ion transport within charge-selective membranes. Here we introduce an uncharged porous separator that enables facile transport of both ion types, reducing ohmic resistance and superconcentrating cations at the catalyst surface—lowering COR voltage by 150 mV at 200 mA cm−2. In previous electrolyser designs, porous separators were limited by cathode-to-anode H2 crossover; the low diffusivity of C2H4 and CO in water allows a separator three times thinner and 1.6 times more porous, markedly reducing overpotential. Operating at elevated temperatures with a nickel–iron-based anode further lowers voltage by 330 mV, leading to a full-cell voltage of 1.95 V at 200 mA cm−2 and an energy efficiency of 51% to C2+ products sustained over 250 h. The system also achieves a CO single-pass conversion of 97% and a C2H4 concentration of 87 wt% in the product gas stream. Electrochemical COx reduction to multi-carbon products is hindered by low energy efficiency, in part due to sluggish ion transport across charge-selective membranes used in electrolysers. Here the authors use a porous, non-charge-selective separator that enhances ion transport and improves performance for CO electrolysis.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 10","pages":"1197-1204"},"PeriodicalIF":60.1,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat pumps contribute to this potential by reducing energy expenses and increasing energy services. We examine the role of adopting heat pumps in mitigating energy insecurity, utilizing electricity records from 8,656 households in Phoenix, Arizona. We use a thermal comfort index to examine a household’s energy-limiting behaviour using a temperature–electricity response function. Our regression results show that households with heat pumps initiate cooling at 0.996 °C lower than those without and consume 0.476 kWh less electricity daily per degree increase in temperature. It indicates that heat pumps improve indoor comfort by activating earlier summer cooling. Cost savings from operation have a rebound effect of enabling greater comfort. Furthermore, this adoption reduces the energy equity gap across income groups, resulting in more similar and comfortable cooling start temperatures. This study supports the adoption of clean technologies to reduce energy insecurity. US households with heat pumps begin cooling earlier, and this adoption narrows the income-based disparities in cooling. Heat pumps help alleviate energy insecurity, make energy more affordable and make homes more comfortable.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 9","pages":"1166-1177"},"PeriodicalIF":60.1,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145204893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
