The 2-hour battery energy storage system (BESS) is the largest in Hungary, Switzerland-headquartered MET Group said, deployed at its Dunamenti thermal power plant in Százhalombatta, near Budapest.
The new facility supports a growing push to green Hungary’s power grid. Hungary has just switched on its largest battery energy storage system (BESS) to date, stepping up its role in Central Europe’s growing grid-scale energy transition.
MET Group has switched on Hungary’s largest battery, a 40 MW/80 MWh system, at the site of a power station near Budapest. From ESS News Swiss-based energy company MET Group has officially inaugurated Hungary’s largest standalone battery energy storage system (BESS) at its Dunamenti Power Station in Százhalombatta, located close to Budapest.
The new facility boasts a total power output of 40 MW and a storage capacity of 80 MWh. This project significantly expands MET Group’s energy storage portfolio in Hungary. It joins a smaller 4 MW / 8 MWh demonstrator BESS, which utilizes Tesla Megapack 2 batteries and was installed at the same site in 2022.
Lithium-ion batteries (LIBs) and hydrogen (H 2) are promising technologies for short- and long-duration energy storage, respectively. A hybrid LIB-H 2 energy storage system could thus offer a more cost-effective and reliable solution to balancing demand in renewable microgrids.
Battery energy-storage systems typically include batteries, battery-management systems, power-conversion systems and energy-management systems 21 (Fig. 2b).
Compared to Just LIB or Just H2, the hybrid system provided significant cost reductions (see Fig. 5). Relying on only LIB for energy storage ($74.8 million) was more expensive than relying on only H 2 ($59.2 million), and significantly more expensive than the hybrid case ($43.3 million).
The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
Electrical energy storage systems (ESS) commonly support electric grids. Types of energy storage systems include: Pumped hydro storage, also known as pumped-storage hydropower, can be compared to a giant battery consisting of two water reservoirs of differing elevations.
Variable power is produced by several renewable energy sources, including solar and wind. Storage systems can help to balance out the supply and demand imbalances that this produces. Electricity must be used promptly when it is generated or transformed into storable forms.
Zakeri and Syri also report that the most cost-efficient energy storage systems are pumped hydro and compressed air energy systems for bulk energy storage, and flywheels for power quality and frequency regulation applications.
