Special Issue Information
Dear Colleagues,
To accelerate the construction of a low-carbon power system with renewable energy as the mainstay, it is crucial to address the technical challenges arising from the large-scale integration of renewables—such as the spatial and temporal variability of wind and solar resources, and the complexity of their coordinated planning with the power grid. In this context, the rapid development of energy storage technologies has become an urgent need.
Among various energy storage solutions, Pumped Hydro Compressed Air Energy Storage (PH-CAES) stands out by integrating the complementary advantages of both pumped hydro storage and compressed air energy storage. It features high energy density, excellent efficiency, short construction periods, and strong rotational inertia. To promote the academic and engineering progress of this promising technology, we are pleased to launch this Special Issue, titled "Advanced Pumped Compressed Air Energy Storage: Systems and Key Technologies", aiming to introduce and disseminate the latest advances the in theory, system design, equipment manufacturing, modeling, application, control, and monitoring of PH-CAES technologies.
This Special Issue welcomes contributions on, but not limited to, the following topics:
- Optimal design methodologies for PH-CAES systems;
- Coordinated control technologies for PH-CAES systems;
- The design and manufacturing of composite material pressure vessels;
- Thermal energy storage technologies and high-efficiency thermal storage equipment;
- Retrofitting technologies for high-pressure caverns or abandoned mines;
- Heat and mass transfer mechanisms and energy flow coupling in water–air combined chambers;
- Design and manufacturing of high-efficiency pump–turbine units under wide load variation conditions;
- Erosion and wear resistance technologies for hydraulic machinery;
- Impact analysis and mitigation strategies of deep peak shaving on hydropower units;
- Key technologies for hydropower plant trash removal and cleaning;
- Life-cycle safety assurance and economic evaluation of underground cavern linings;
- Design technologies for expansion turbines operating under ultra-wide hydraulic head variations;
- Optimization strategies and control system development for pump–turbine units under ultra-wide operating conditions;
- Safety and stability analysis and high-efficiency operation strategies for PH-CAES 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).
