In the last five years, the renewable energy sector has been growing very fast. If this trend is confirmed, renewables will account for more than 90% of the global electricity capacity by 2050 to achieve the zero-net emission target.
So far, several new technologies have been applied to exploit efficiently renewable sources, and some of them, like hydropower and wind energy, deal with the use of rotating machines. An increasing interest is also developing in the field of mechanical energy storage (e.g., pumped storage hydropower, compressed air energy storage, etc.). In addition, recent studies have also focused on the use of hydrogen fueled gas turbines: if the hydrogen is produced by renewables (e.g., green hydrogen), this technology will break pollutant emissions down completely, thus promoting the application of already established equipment to come to a new life.
This collection aims to provide a further insight in the operational features and use of these machines by providing research and innovation contributions through Computational Fluid Dynamics (CFD) analyses, laboratory tests, and real scale applications. In particular, this Research Topic aims to address the following aspects:
• Design and analysis of either new or existing technologies that are used or developed for being employed with either renewable sources or energy vectors (e.g., green hydrogen);
• Reviews and mini-reviews on the current state of the art of rotating machines’ application in the renewable energy sector that highlight the important future directions of this research field;
• Application and design optimization of rotating machines (e.g., gas turbines, hydraulic turbines, pump-turbines, wind turbines, wave energy converters, etc.) for power generation, investigated through CFD analyses, laboratory and field tests. Technologies applied in real environments are also welcome;
• Research works that focus on unsteady interactions analyses (e.g., rotating-stationary domain interface), design optimization studies, performance evaluation/forecast models, and modern non-intrusive experimental techniques.

All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
