What is green2store and sonnenBatterie?

Green2store is a project which uses the energy storage units in a local network together as one large storage facility . Sonnenbatterie, a Germany based company, aims at providing an energy storage solution to residential users, including software and energy storage units .

How can energy storage technology help reduce energy costs?

Investment in energy storage technologies globally is likely to reduce initial capital costs for consumers looking to incorporate storage options within their renewable energy systems. Global investment in improving technology can also assist in lowering costs of operating and maintaining small-scale renewable energy systems.

What types of energy storage can be used for short-term energy storage?

For short-term energy storage, there is also the possibility to use direct Electrical Energy storages (EES) such as Super Capacitors (SC) [13, 14] and Superconducting Magnetic Energy Storage (SMES) , which are mainly used as grid stabilisation units.

Why do we need energy storage systems?

In the future, the share of renewable energy such as solar photovoltaics (solar PV) and wind energy will increase in the electrical grid utilities, which will cause power and frequency fluctuations. Therefore, SC, SMES, and FES energy storage systems are necessary components for stabilising modern electrical grids.

What is the new type of energy storage?

The new type of energy storage is an Electro-thermal Energy Storage System (ETES) that uses FPSE and thermal storage materials for sensible heat storage. The proposed ETES does not use any critical materials, and it is easy to disassemble and recycle.

What is a large-scale grid storage?

The most common large-scale grid storages usually utilize mechanical principles, where electrical energy is converted into potential or kinetic energy, as shown in Fig. 1. Pumped Hydro Storages (PHSs) are the most cost-effective ESSs with a high energy density and a colossal storage volume .
