Segmented packed beds for improved thermal energy

Abstract: A scheme for bulk electricity storage known as Pumped Thermal Energy Storage (PTES) is described. PTES uses a heat pump during the charging phase to create a hot and a cold storage space. During discharge, these thermal stores are depleted using a heat engine. This version of PTES uses packed beds (or pebble beds) as the energy store.

6 FAQs about [Ptes energy storage French Polynesia]

What are thermal storage systems for PTEs?

Thermal storage systems for PTES Energy storage is a vast field of study that encompasses thermal, electrical, chemical, and mechanical energy storage technologies [20, , , ]. The technologies differ immensely in their usage and there is no single system that can be employed universally.

How is electricity stored in a PTEs system?

In PTES systems, however, electricity is stored in the form of thermal energy which requires heat to be retrievable for employing charging and discharging cycles.

What is PTEs technology?

The PTES technology can be a valuable resource for storing large amounts of energy efficiently and economically, particularly when combined with Sensible Heat Thermal Energy Storage (SHTES).

Will PTEs become a game changer in thermal energy storage?

Thermo-economic analyses show that PTES systems are quite cost-competitive to already mature technologies like PHES. With further investigations and performance enhancements, PTES will only improve its prospects of becoming a game changer in thermal energy storage. 1. Introduction

What is the thermodynamic potential of a PTEs system?

Using sensible heat storage tanks, Roskosch et al. [ 83, 84] analysed the general thermodynamic potential and limits of a PTES system consisting of a compression heat pump, a thermal storage unit and an ORC system, with results showing roundtrip efficiencies in the range of 37%–56%.

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 .
