Energy storage technology index engineering planning ranking

What are the three energy storage technologies?

This paper addresses three energy storage technologies: PH, compressed air storage (CAES) and hydrogen storage (Figure 1). These technologies are among the most important grid-scale storage options being intensively discussed today.

Which energy storage technology is most cost-efficient?

Fundamental indicators considered are their respective efficiencies, capital expenditure and operational expenditure, and technical service lives. From an economic point of view, today pumped hydro is the most cost-efficient short- and medium-term storage technology, closely followed by compressed air energy storage.

Which technologies exhibit potential for mechanical and chemical energy storage?

Florian Klumpp, Dr.-Ing. In this paper, technologies are analysed that exhibit potential for mechanical and chemical energy storage on a grid scale. Those considered here are pumped storage hydropower plants, compressed air energy storage and hydrogen storage facilities.

Is pH a good energy storage option for LTS?

A critical factor for the poor performance of hydrogen stores is their very high specific power-dependent Capex in combination with their short service lives and low overall efficiencies. When deployed for LTS, though, the picture changes. For this dispatch scenario, PH is the costliest means of energy storage.

How are storage technologies analysed?

Many national and international papers analyse storage technologies with regard to their technical elements, such as efficiency and typical capacity, and their economic data – for example, capital expenditure (Capex), operational expenditures (Opex) and so on (CLCF, 2013; Crotogino, 2010; Rastler et al., 2012).

What technologies are available for utility-scale storage facilities?

For utility-scale storage facilities, various technologies are available, including some that have already been applied on a large scale for decades – for example, pumped hydro (PH) – and others that are in their first stages of large-scale application, like hydrogen (H 2) storage.
