Over the past decade, an abundance of work has been carried out at ambient temperature, and high CO2E rates and product selectivities have been achieved. With scaling of CO2E technologies underway, greater discourse surrounding heat management and the viable operating temperatures of larger systems is important. In this Perspective we argue that, owing to the energy inefficiency of electrolysers, heat generation in CO2E stacks will favour operating temperatures of between 40 and 70 °C, far from the ambient temperatures used so far. Such elevated temperatures put further pressure on catalyst and membrane stability and on the stack design. On the other hand, elevated temperatures could alleviate challenges in salt precipitation, water management and high cell voltages, aiding the technology. We reflect on these aspects and discuss the opportunities for waste heat valorization to increase the economic feasibility of the process. Low-temperature CO2 electrolysers are often tested at ambient temperature, yet this may not be optimal for larger-scale systems. In this Perspective Pelzer et al. argue that heat generation, due to the energy inefficiency of electrolysers, will favour elevated operating temperatures of 40–70 °C.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 5","pages":"549-556"},"PeriodicalIF":60.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880489","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}

Understanding the extent and mechanisms of rapid progress in white LED technology can provide valuable insights for accelerating innovation in other demand-side clean energy technologies critical for reducing global carbon emissions. Here we show, through cost and performance modelling based on data from literature review, patent analysis and expert interviews, that the efficiency of top-performing warm white GaN-based LED packages increased from 5.8% in 2003 to 38.8% in 2020. Over the same period, the manufacturing cost of low-to-mid-power LED packages decreased by 95.5% from US$1.1 to US$0.05 (in 2020 US dollars). We find that technology spillovers from other sectors accounted for at least 8.5% of efficiency improvements and nearly all consumer experience enhancements, playing an important role in widespread LED adoption in lighting. From 2003 to 2020, the efficiency of white light-emitting diodes rose from 6% to 39%, while costs fell by 96%. Weinold et al. explore the drivers of such rapid progress to formulate lessons for future clean energy innovation.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 5","pages":"616-629"},"PeriodicalIF":60.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41560-025-01757-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spin manipulation in the OER is a promising approach by which to modulate the reaction pathway to improve the energetics and kinetics. To that end, application of magnetic fields in the OER has been shown to enhance performance; however, whether the underlying promotional mechanisms are spin-related or non-spin-related remains a topic of ongoing debate. In this Review we explore OER enhancement under magnetic fields and elucidate both spin-related and non-spin-related effects, examining key fundamentals and experimental practices to distinguish these effects. For spin-related mechanisms, we highlight the key effects of spins on the catalyst bulk, catalytic interface and reaction intermediate. We provide guidance for understanding whether enhancements are spin-related or not. Magnetic fields have been shown to improve water oxidation performance, but the nature of the underlying promotional mechanisms remains unclear. In this Review the authors examine the possible phenomena at play and provide guidance on how to determine whether key enhancements derive from spin-related effects or not.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 4","pages":"435-447"},"PeriodicalIF":60.1,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872548","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}
