Through an analysis of green ammonia production with solar and wind energy at more than 4,500 locations across Europe, this work demonstrates that maximizing cost efficiency is decoupled from maximizing energy utilization due to the intermittency of renewable energy. By devising the metric of levelized cost of utilization, the economic drive for energy curtailment is connected to the high cost to utilize portions of solar or wind energy profiles with unequal seasonal distribution. Combining solar and wind energy or ramping production decreases the cost of utilizing energy, thereby decreasing curtailment. A framework for evaluating the power-to-x economics within the context of electricity grids is illustrated using the value of utilizing energy, which indicates that electrified chemicals production is an attractive market for renewable energy at locations with high penetration on the grid.","PeriodicalId":501699,"journal":{"name":"Nature Chemical Engineering","volume":"2 4","pages":"261-272"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12018267/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144036902","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 approach relies on an evolving oxygen chemical potential gradient within a reactor bed. Here we show that the oxygen-sensitivity of operando neutron powder diffraction experiments can reveal how the reactor functions with high spatial- (≲1 cm) and time- (≲30 s) resolution. We show how this operando method enables rapid testing of new high-capacity bed materials without previous knowledge of their thermodynamic properties, and gives direct information on their long-term stability. We introduce how this memory reactor concept can also be applied to the steam methane reforming reaction (CH4 + H2O ⇋ CO + 3H2), the key preprocess to the water-gas shift reaction in H2 production.","PeriodicalId":501699,"journal":{"name":"Nature Chemical Engineering","volume":"2 7","pages":"447-455"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12283380/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710462","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}

However, delivering oligonucleotides to tissues beyond the liver remains a key challenge, limiting their clinical applications thus far to niche indications. To achieve broader applicability, extensive biomolecular engineering is necessary to enhance the stability, tissue targetability, pharmacokinetics and pharmacodynamics of these structures. The intricate design of these molecules also demands sophisticated process-engineering techniques. Here we provide a collaborative Perspective from academia and industry on the pivotal role of chemical engineering in expanding the use of therapeutic oligonucleotides to treat a wider range of diseases. We discuss how the interplay between biomolecular and process engineering impacts the developability of next-generation oligonucleotide therapeutics as well as their translation from bench to bedside. Oligonucleotide therapeutics have emerged as a promising alternative to traditional small-molecule and protein-based drugs. This Perspective discusses how chemical engineering can broaden oligonucleotide applications to extrahepatic diseases and enable larger-scale production, ultimately allowing treatment of more prevalent conditions than is currently possible.","PeriodicalId":501699,"journal":{"name":"Nature Chemical Engineering","volume":"1 12","pages":"741-750"},"PeriodicalIF":0.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142875305","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}
