Please describe in detail including the TRL Level:
A novel and low cost biochar PCM hybrid latent heat energy storage material have been developed and tested The biochar is prepared from aquatic invasive weed plants by using a batch type pyrolyser The characteristics and properties of the novel energy storage material have been evaluated using various experimental and analytical methods The methods include Brunauer Emmett and Teller BET Scanning electron microscope SEM Xray powder diffraction XRD Differential Scanning Calorimetry DSC Thermogravimetric analysis TGA Fouriertransform infrared spectroscopy FT IR and thermal conductivity tester Simple Impregnation method has been used to prepare form stable composite material which has good thermal and structural stability The best mixing ratio PCM biochar is found to be 6 is to 4 wt percentage with minimum leakage of PCM from the composite The chemical properties of the composite remain the same as the pure PCM which confirms no chemical interaction between the PCM and biochar The heat of fusion is calculated to be 179 Jg The thermal conductivity of the PCM is enhanced up to 13 point 82 times with the addition of water hyacinth biochar as a supporting matrix The addition of aluminum metal powder further increases the thermal conductivity by 17 point 27 times higher than that of PCM alone A prototype of solar dryer was developed with the developed composite storage material to achieve isothermal drying

    Abstract:

Applications: An indirect type forced convection solar dryer is developed incorporating the biocomposite based TES system in the form of a shell and tube heat exchanger The developed TES system is expected to give isothermal drying conditions specifically suited for turmeric drying A different biocomposite has been prepared using the same procedure for the application on the PV T system The PCM for the new material is selected keeping in view the operating temperature of the PV panel The new material has been applied to the backside of the PV panel for increasing electrical efficiency and uniform cooling of the PV panel and also for the continuous generation of low temperature fluid A passive building system with the biocomposite PCM will be designed for temperature regulation
Advantages: The biocomposite material formed in this work is able to overcome two problems of conventional PCM material. The best combination for overcoming leakage problem is found to be 6 is to 4 PCM Biochar wt percentage biocomposite material The thermal conductivity increased up to 13 point 82 times with the new biocomposite over PCM The addition of Aluminum metal powder further increases the thermal conductivity by 17 point 27 times higher than that of PCM alone The melting temperature of the composite is found to be 57 point 67 degree Centrigade which is slightly lower than that of pure PCM The heat of fusion is calculated to be approximately 179 point 4 Jg which is reasonably comparable with the earlier works form literature The charging and discharging time is found to be more than that of pure PCM imparting better thermal retention properties over PCM No chemical reactions occurred during the formation of biocomposite resulting in the same chemical properties and crystalline structure of the PCM used as confirmed by SEM XRD and FTIR comparison analysis

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
