Technologies of Energy Storage, Carbon Capture, Utilization and Storage

Dear Colleagues,

In the context of global efforts to combat climate change, the commitment to reducing carbon emissions and achieving sustainable development is increasingly strengthening worldwide. Energy storage and carbon capture, utilization, and storage technologies play a crucial role in mitigating carbon emissions. Moreover, large-scale energy storage can significantly enhance the utilization of renewable energy, balance grid load, reduce energy costs, and improve the flexibility and security of energy systems.

Nonetheless, these technologies encounter a variety of challenges, including the need to enhance energy storage efficiency, lower costs, improve the economic viability of carbon capture, guarantee the long-term stability and safety of large-scale energy storage and carbon sequestration, and discover more effective methods for integrating renewable energy systems. For example, mechanical energy storage (such as pumped hydro storage and compressed air energy storage) primarily faces geographical and efficiency limitations, while electrochemical energy storage (such as batteries and hydrogen storage) is challenged by costs, material sustainability, efficiency, and insufficient infrastructure. In particular, underground energy storage and carbon sequestration technologies, as potential solutions for long-duration, large-scale energy storage and carbon sequestration, also face substantial technical and economic challenges in their development.

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 250 words) can be sent to the Editorial Office for assessment.

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. Sustainability 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 2400 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.
