6 FAQs about [Liquid gold energy storage and heat dissipation]

Does liquid gold have a constant heat capacity?

There is a lack of data for the heat capacity of liquid gold. There have been only two direct measurements using quasi-adiabatic calorimetry by Vollmer and Kohlhaas , and using a DSC technique by Wilde et al. . The data from Vollmer and Kohlhaas shows a constant heat capacity .

Why do companies use liquid metals for energy storage?

“When the liquid metal is heated with power from renewable energy sources, companies have an efficient solution to mitigate fluctuations of power supply and to enable simple, inexpensive, and rapid energy storage at temperatures that are as close as possible to those used in industrial processes,” Niedermeier points out.

What is the thermodynamic data for pure gold?

Thermodynamic data for pure gold were critically assessed using an extended Einstein model from 0 K for the crystalline FCC_A1 phase and a two state model for the liquid phase. During the assessment, careful critical evaluation of the experimental data on thermodynamic properties of solid (FCC_A1) and liquid phases was carried out.

Can liquid metals be used in heat storage systems?

So far, liquid metals have hardly been used in heat storage systems. According to Niedermeier, this is mainly due to logistical reasons. There are only a few closed-loop systems in the world, in which such a heat storage system can be tested.

Does liquid metal improve heat storage efficiency?

Simulations at KIT’s liquid-metal laboratory KALLA have confirmed that the use of liquid metal increases the efficiency of heat storage, especially when a very compact package is used. Efficient Storage of Excess Green Power

Can a liquid-metal heat storage system store 100 kilowatt-hours of heat?

The system at KIT is designed to store 100 kilowatt-hours of heat and has been tested on the laboratory scale at temperatures of up to 400 °C so far. “This is the world’s liquid-metal heat storage system of this kind with such a capacity. We want to show that the principle works and that it has great potential,” says Klarissa Niedermeier.
