Negotiations with these landowners have important economic, environmental and social implications. In this paper we present a dataset on negotiations in Ohio and use these data to investigate how landowners may be advantaged or disadvantaged in these lease negotiations. We find that they are disadvantaged in two ways. First, because energy companies can use persistent and personal strategies to overcome landowner reluctance. Second, because of the institutional context: specifically the widespread use of compulsory unitization. We conclude by discussing the implications of these findings for equity in energy policy and by drawing out the other potential uses of these data. Energy companies must often obtain consent from private landowners for natural gas extraction. This study analyses lease negotiations between these two parties in Ohio, noting disadvantages on the side of the landowner in the process.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 11","pages":"1369-1377"},"PeriodicalIF":49.7,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142002805","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, most reported systems are sensitive to molecular oxygen, severely limiting their application under ambient air conditions. Here we demonstrate an electrochemical carbon capture concept via non-aqueous proton-coupled electron transfer, where alkoxides are employed as the active sorbent while carbon dioxide absorption and desorption are modulated reversibly by the redox-tunable Brønsted basicity of certain organic molecules. Since all species involved in the process have outstanding oxygen stability and relatively low vapour pressure, our electrochemically mediated carbon capture mechanism intrinsically minimizes parasitic reactions and evaporative losses under aerobic conditions. Flow-based prototypes are demonstrated to operate efficiently in the presence of 20% oxygen under various practically relevant carbon dioxide feed concentrations, paving a way towards effective carbon capture driven by electrochemical stimuli. Sensitivity to O2 hinders the application of some electrochemically mediated carbon capture technologies under ambient air conditions. Here the authors report electrochemical CO2 capture via non-aqueous proton-coupled electron transfer, employing alkoxides as active sorbents, in which all species involved are highly air stable.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 11","pages":"1415-1426"},"PeriodicalIF":49.7,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141991812","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 find that mixed Sn–Pb perovskite thin films exhibit a compositional gradient, with an excess of Sn on the surface—and we show this gradient exacerbates oxidation and increases the recombination rate. We find that diamines preferentially chelate Sn atoms, removing them from the film surface and achieving a more balanced Sn:Pb stoichiometry, making the surface of the film resistive to the oxidation of Sn. The process forms an electrically resistive low-dimensional barrier layer, passivating defects and reducing interface recombination. Further improving the homogeneity of the barrier layer using 1,2-diaminopropane results in more uniform distribution and passivation. Tandems achieve a power conversion efficiency of 28.8%. Encapsulated tandems retain 90% of initial efficiency following 1,000 h of operating at the maximum power point under simulated one-sun illumination in air without cooling. The stability of perovskite tandem solar cells is an issue.

Here we gathered year-long records from 61,598 electric trucks in China. Current electric trucks were found to be significantly underutilized compared with their diesel counterparts. Twenty-three per cent of electric delivery trucks and 30% of semi-trailers could achieve one-on-one replacement with diesel counterparts, while on average 3.8 electric delivery trucks and 3.6 electric semi-trailers are required to match the transportation demand that is served by one diesel truck separately. For diesel trucks that are capable of one-on-one replacement, electric trucks have 15–54% and 1–49% reductions in cost and life-cycle CO2 emissions, respectively. Enhancements in usage patterns, vehicle technologies and charging infrastructure can improve electrification feasibility, yielding cost and decarbonization benefits. Increased battery energy densities with optimized usage can make one-on-one electrification feasible for more than 85% of diesel semi-trailers. In addition, with cleaner electricity, most Chinese electric trucks in 2030 will have lower expected life-cycle CO2 emissions than diesel trucks. Truck electrification is an important but challenging task for decarbonization. Here the authors investigate usage data from >60,000 electric trucks to pose category-tailored strategies for overcoming the hurdles of feasibility, cost and decarbonization in this sector.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 11","pages":"1427-1437"},"PeriodicalIF":49.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141918866","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}

Previous research has emphasized the role of iodide and silver oxidation, and the role of hole tunnelling from the electron-transport layer into the perovskite to enable the flow of current under reverse bias in causing degradation. Here we show that device architecture engineering has a significant impact on the reverse bias behaviour of perovskite solar cells. By implementing both a ~35-nm-thick conjugated polymer hole transport layer and a more electrochemically stable back electrode, we demonstrate average breakdown voltages exceeding −15 V, comparable to those of silicon cells. Our strategy for increasing the breakdown voltage reduces the number of bypass diodes needed to protect a solar module that is partially shaded, which has been proven to be an effective strategy for silicon solar panels. Perovskite solar cells degrade when subjected to reverse bias. Jiang et al. show that relatively thick hole transport layers and metal back contacts with improved electrochemical stability afford better tolerance to reverse bias.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 10","pages":"1275-1284"},"PeriodicalIF":49.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141899746","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, non-precious metals used in AEMFCs to catalyse the hydrogen oxidation reaction are prone to self-oxidation, resulting in irreversible failure. Here we show a quantum well-like catalytic structure (QWCS), constructed by atomically confining Ni nanoparticles within a carbon-doped-MoOx/MoOx heterojunction (C-MoOx/MoOx) that can selectively transfer external electrons from the hydrogen oxidation reaction while remaining itself metallic. Electrons of Ni nanoparticles gain a barrier of 1.11 eV provided by the QWCS leading to Ni stability up to 1.2 V versus the reversible hydrogen electrode (VRHE) whereas electrons released from the hydrogen oxidation reaction easily cross the barrier by a gating operation of QWCS upon hydrogen adsorption. The QWCS-catalysed AEMFC achieved a high-power density of 486 mW mgNi−1 and withstood hydrogen starvation operations during shutdown–start cycles, whereas a counterpart AEMFC without QWCS failed in a single cycle. Non-precious metals used at the anode of anion-exchange-membrane fuel cells to catalyse hydrogen oxidation are prone to self-oxidation.
