What factors affect the financial feasibility of energy storage systems?

Furthermore, another factor that affects the capacity and subsequently the financial feasibility of energy storage systems is the size and location of the modelled solar PV system.

What is the optimal capacity of solar energy storage systems?

Hence, the optimal capacity of all the energy storage systems is zero, whereas the feasible solar PV size is limited to below 20 % when using the 2019 electricity prices as comparison.

Can energy storage systems be used in residential buildings in Nordic climates?

Methodology To evaluate the financial feasibility of implementing energy storage systems in residential buildings in Nordic climates, the use of energy storage technologies in combination with a solar PV system was modelled for detached houses employing different heating methods in Southern Finland.

What is the efficiency of a battery storage system?

For the battery storage system, a 90 % round-trip efficiency was used, representing the use of a generic LIB , . For the H 2 energy storage system, a 30 % round-trip efficiency was used, a value that could also be lower for small-scale energy storage applications.

What is high temperature thermal energy storage?

High temperature thermal energy storage offers a huge energy saving potential in industrial applications such as solar energy, automotive, heating and cooling, and industrial waste heat recovery. However, certain requirements need to be faced in order to ensure an optimal performance, and to further achieve widespread deployment.

What are the chemical requirements for heat storage materials?

Chemical requirements are very similar for sensible and latent heat storage materials ( Table 2 ). Candidate materials should have long-term chemical stability, no chemical decomposition, should be compatible with the container materials and the HTF, non-toxic and non-flammable, and they should present no phase segregation.
