Ranking of Electricity Accumulation Possibilities: Multicriteria Analysis

The pace of the implementation renewable electricity storage in Europe is disappointingly slow. Several factors influence this and there a need to speed up rate increase volumes order promote 100% transition energy resources, expand practice using energy, contribute improvement quality life consumers. An important factor significantly reducing impact on environment climate change. Electricity from sources such as solar wind has seasonal nature that cannot provide necessary consumption cover peak loads. so-called “energy resource crisis” also very topical problem at moment, which reinforces global share resources overall balance primary resources. Practical wider integration what can help stimulate this. availability constantly increasing, level technological innovation rapidly developing. Therefore, it valuable analyse, look for connections ways accumulate its private homes national scale more broadly European scale. article analyses compares different options storage, small batteries large systems, arriving best solution according needs, analysis methods multicriteria decision (MCDA) TOPSIS. After comparing nine criteria, amount investment required, existing power density, efficiency, duration operation, others two groups (small accumulation systems), was concluded lithium-ion are currently among batteries, while pumped hydro systems.
