Spelling Error in Energy Storage Findings?

In summary, experts in adsorption physics state that water adsorbed in a mineral called bentonite can store as much as 30 kJ/g. However, their research shows a fatal error published stating that the correct figure may be 1000 times smaller with only 30kJ/kg as enthalpy per mass of heat storage material.

Hello to all Experts in Adsorption Physics!
Here is a research paper, stating that water adsorbed in a mineral called bentonite can store as much as 30 kJ/g. According our research and findings with such water based latent heat or phase change storage systems, there seem to be a fatal error published. The correct figure may be 1000times smaller with only 30kJ/kg as enthalpy per mass of heat storage material. See abstracts and publication below. By the way, our PCM has a capacity of 1000kJ/kg. Thanks for looking into this. Johann

Abstract
Adsorption/desorption of water vapour on raw Saudi bentonite (RB) is proposed as a heat energy storage. This is most readily achieved by adsorption and desorption of water vapour on RB at different temperatures as a function of time. The RB subjected to preheating temperature of 200 °C, before subjecting to the adsorption process carried out. The IR spectra of RB before adsorption of water vapour at 298 and 313 K were studied. The adsorbed and desorbed water vapour from bentonite surfaces at 298 and 313 K was determined at different time. The adsorptive capacities of RB sample at 298 and 313 K were 0.0097 and 0.0141 mol/g of dry RB, respectively, after 72 h. The desorbed amounts are 0.0085 and 0.01 mol H2O/g of RB at 298 and 313 K, respectively after 72 h. A kinetic models of second order of the adsorption and desorption of water vapour fitted well the experimental data. Application of Van’t Hoff’s law at two temperatures (298 and 313 K) yields the adsorption and desorption enthalpy. The adsorption enthalpy (stored energy) of RB increased with increasing contact time up to 5 h. At this time the maximum enthalpy was about 30 kJ/g dry bentonite, at which the clay has lost all the energy that could be released due to adsorption of water vapours. Then it shows a decrease in sorption energy when the time increases. On the other hand, the desorption enthalpy increases gradually with the increase of the time up to 72 h then become constant, maximum enthalpy was 14.99 kJ/g. The rate of water vapour adsorption was found to be very high so that the extracted energy from the bentonite surface would not be a problem in any practical utilization of this system.

Thank you for bringing this to our attention. As scientists, it is important for us to ensure the accuracy of our findings and published data. We will look into the issue and make the necessary corrections if needed. However, it is also important to note that experimental data and results can vary due to different factors such as experimental conditions and methods. We appreciate your contribution to the research in energy storage and your clarification on the correct figures. This will help us in further understanding and improving energy storage systems.
 

1. What is a spelling error in energy storage findings?

A spelling error in energy storage findings refers to a mistake in the written word that relates to the research and findings of energy storage. This could be a typo, misspelled word, or incorrect usage of a term.

2. How can a spelling error affect the results of energy storage findings?

A spelling error can have a significant impact on the results of energy storage findings. It can lead to a misinterpretation of data, incorrect conclusions, and ultimately, inaccurate scientific information.

3. What are the common causes of spelling errors in energy storage findings?

Spelling errors in energy storage findings can occur for various reasons, including human error, fast-paced research environments, and lack of proofreading or editing. They can also happen due to technical issues or using unfamiliar terms.

4. How can scientists prevent spelling errors in energy storage findings?

To prevent spelling errors in energy storage findings, scientists should take the time to carefully proofread their work and use spell-checking tools. It is also helpful to have a colleague review the research before publication to catch any errors.

5. Are spelling errors in energy storage findings a common occurrence?

While spelling errors in energy storage findings can happen, they are not a common occurrence among scientists. Most researchers understand the importance of accuracy in their work and take necessary precautions to avoid spelling errors.
