Special Issue Information
Dear Colleagues,
Flywheel energy storage has the potential to play a significant role in the transformation of electrical power systems to those with the highest sustainability yet lowest cost. The penetration of renewable energy generation has created new challenges, which ultimately can only be solved by means of fast response energy storage. For example, as synchronous generation is removed from electricity grids, the ability of the system to maintain a steady frequency is compromised. Here lies the opportunity for flywheel storage, whose characteristics typically place it between ultra-capacitors and electrochemical batteries. Although electrochemical batteries are currently dominating the market for fast response storage, flywheels offer a very high cycle and calendar life, and are fully sustainable in terms of raw materials’ ease of recycling. Flywheels may also be hybridized with batteries in order to benefit from the strengths of each technology. As well as stationary grid applications, flywheels may be deployed for energy recovery in transport, either on board the vehicles or at strategic locations, for instance, in railway stations.
Contributions are invited in the following areas:
- Rotor research including safety and containment
- Low loss bearing systems
- Novel motor-generator technologies and drives
- Integrated flywheel motor-generator systems
- Vacuum systems
- Rotor dynamics
- Hybrid micro and mini grids—integration of renewables with flywheel storage
- Hybrid storage system—integration of flywheel storage with batteries or other storage systems
- Trackside storage in electrified rail transport
- Vehicle kinetic energy recovery

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.
