6 FAQs about [Algeria ptes energy storage]

What is pit thermal energy storage (PTEs)?

Pit thermal energy storage (PTES) is one of the most promising and affordable thermal storage, which is considered essential for large-scale applications of renewable energies. However, as PTES volume increases to satisfy the seasonal storage objectives, PTES design and application are challenged.

What is a PTEs battery?

It is a form of a Carnot battery configuration that utilizes electrical energy input to drive a temperature difference between two reservoirs, thereby storing electrical energy in the form of thermal exergy . PTES is still a developing technology and thus its efficiency is lower than that of PHES (Hydro) or CAES .

Which PTEs systems employ sensible heat storage?

Three main PTES system variants employing sensible heat storage are considered in this work: (i) reversible Joule-Brayton PTES systems with STRs, (ii) reversible Joule-Brayton PTES systems with LTSs, and (iii) reversible transcritical Rankine PTES systems with LTSs.

What type of heat exchanger is used in PTES systems?

The most commonly employed heat exchanger type is the shell-and-tube heat exchanger, which is selected here as the heat transfer device in all the considered PTES systems.

Does geometry affect PTEs thermal and economic performance?

At present, the geometry of PTES of most projects is regular, but due to the influence of geological conditions, more and more irregular-shaped PTES may appear. In this context, it is vital to understand the impact of geometry changes on PTES thermal and economic performance.

How does PTEs work?

The early conceptualization of the PTES system suggests that the working principle is based on the first Ericsson cycle which creates a thermal split about a datum temperature . The technology has been patented in different forms by several authors.
