Many strategies are currently being researched to enable the use of electrical energy from renewable resources for chemical synthesis [1, 2]. This contribution shows the possibility of obtaining basic chemicals by conversion using microwave plasma technology. A challenge for renewable energies, in addition to the storage problem, is the dependence on weather conditions. The plasma technology approach provides excellent flexibility in controlling of the process and thus in utilizing the fluctuating availability of cost-effective renewable energies.

Three future development scenarios were defined. One, focusing on high efficiencies, reaches NPC of 2.9 EUR L⁻¹ of marine diesel. The approach of prioritizing high CO₂ conversion results in costs of 3.7 EUR L⁻¹. A more balanced approach between efficiency and conversion achieves an NPC of 2.6 EUR L⁻¹. Further NPC reductions are possible by sourcing lower-cost renewable electricity, reducing the NPC further to a minimum of 1.6 EUR L⁻¹. These findings underscore that direct air capture (DAC) cost-efficiency and process integration improvements are essential for scalable, economically viable CO₂ utilization in PtL processes.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 5","pages":"454-462"},"PeriodicalIF":1.5,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202400143","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This photo-optical approach allows for a precise in-situ visualization of the droplet size distribution in the reaction mixture and a calculation of the liquid-liquid interface, offering critical insights into the impact of the interfacial area on overall reaction efficiency.
