A kutatási téma leírása:

a.) Preliminaries:
Power generation from renewable energy sources has several problems caused by weather-dependent elements. Production can vary widely, creating new kinds of storage problems, especially in countries where summer PV-based generation is not matched by winter wind-based complementary generation. Problems for handling transients requiring short duration and/or small storage capacity and are currently available, but solutions for large (e.g. supplying the night-time needs of an entire city with electricity generated by solar panels during the day) or even larger capacity and long storage duration (e.g. supplying the winter needs of a municipality from summer generation) often present insoluble problems with current instruments. There is a need to investigate the feasibility of better use of existing methods and to develop new energy storage methods.

b.) Aim of research:
Recently, in addition to conventional pumped storage, other gravity storage solutions (including underground ones), geological storage using high-pressure gases, and power-to-fuel solutions are becoming increasingly important; of the latter, ammonia, methane or liquid fuel methods that are easier to transport-store-use, might overtake the most obvious one, based on hydrogen. Also emerging are thermal storage systems such as Carnot batteries. Some of these methods have reached a relatively high level of development, while others exist only in laboratories or in a conceptual level. The main objective of the research is to investigate which of these methods could be suitable for actual grid use, where and how they can be applied in the storage chain, and how they can be integrated with other energy storage solutions.

c.) Tasks, main items, necessary time:
Review of the literature, study of the current maturity of the different technologies, 1 year. Study of the applicability of the most advanced technologies, 0.5 year. Examination of the current state of the art of new technologies, 0.5 semester year. Energy optimisation of filling and discharging technologies for specific methods, 0.5 year. Investigating the role of methods in specific applications, 0.5 year. Writing of publications and thesis, 1 year. The tasks are not necessarily carried out in the above order.

d.) Required equipment:
Computer, access to literature, software, databases.

e.) Expected scientific results:
Conceptual studies of various energy storage systems. Results on the applicability of some specific storage solutions.
