Carnot Battery Technologies

Dear Colleagues,

Energy storage is a vital part of power systems. IEA World Energy Outlook 2020 recently reported that 90% of global energy storage capacity is provided by pumped hydropower facilities, which are geographically limited. Current research and development efforts are focusing on batteries, however, thermal storage and a variety of other technologies that are much less expensive than electric batteries are getting more attention. One of the technologies that is being highlighted in this special issue is Carnot battery which stores electrical energy in the form of thermal energy using resistive heater or heat pump. This system can be integrated with renewable sources, such as wind and solar. The stored thermal energy can be used for electricity generation by using heat engine or it can directly provide process heat/cold for industrial processes. This special issue inquires the submission of articles that will showcase the advancement of the state-of-the-art Carnot batteries. Its topics and aims are intentionally kept broad to gather new solutions and ideas to meet technoeconomic requirements for large-scale electricity storage demand, but also to underscore technical, economic, and social challenges surrounding these technologies. Submissions are encouraged but are not limited to the following general areas:

• Novel concepts and designs of Carnot batteries
• Innovative solutions for the improvement of the existing Carnot batteries
• Integration of renewable-based electricity to Carnot batteries
• Techno-economic studies on large-scale and cost-efficient Carnot batteries
• Energy and exergy efficiency analysis of Carnot batteries
• Transient thermal performance of the heat engine and/or heat pump cycle
• Carnot batteries based trigeneration (electricity, heat, and cold) systems

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
