In order to have a UL 9540-listed energy storage system (ESS), the system must use a UL 1741-certified inverter and UL 1973-certified battery packs that have been tested using UL 9540A safety methods. It’s quite a UL-mouthful, but basically, the batteries and inverter inside a UL 9540-certified ESS have all met product safety standards.

The IEC 62933 series of standards specifically addresses various aspects of ESS, including testing methods (IEC 62933-2-1), safety requirements for grid-integrated ESS (IEC 62933-5-2), safety considerations for grid-integrated ESS (IEC 62933-5-1), planning and performance assessment of ESS (IEC 62933-3-1), and guidance on environmental issues (IEC 62933-4-1).

The maximum energy rating per ESS unit is 20 kWh. The maximum kWh capacity per location is also specified—80 kWh when located in garages, accessory structures, and outdoors and 40 kWh in utility closets or storage spaces. For storage capacities that exceed these limits, non-residential requirements come into play (NFPA 855 Chapters 4-9).

Highlights LAES is potential for frequency regulation, black start, clean fuel, load shifting. Decoupled LAES is flexible, portable, cold-electricity-supply, yet costly currently. Standalone LAES has a round-trip efficiency of 50–60 % and limited economic benefits. Hybrid LAES has compelling thermoeconomic benefits with extra cold/heat contribution.

Gravity energy storage systems operate using similar principles as pumped hydro storage, which is currently the largest source of grid storage. GESS installations use surplus energy to lift heavy blocks, which creates potential energy that can later be converted into electricity when lowered to the ground.

The two primary types of building energy storage presently available in the marketplace are battery storage and thermal storage. Building battery storage is not theoretically different from the familiar use of batteries in home appliances and cars: they store chemical energy to convert it on demand into electrical energy.
