Development, verification and validation of graphene matrix in solar energy driven and heat driven heat pump

Purpose and goal

The purpose of the project is to improve current matrix properties with regard to heat conductivity and cost-effectiveness, thus increasing the efficiency of for example a solar-powered heat pump. The goal is to integrate the graph and take advantage of its good thermal conductivity as well as its ability to provide strength and structure to the salt matrix. The project has also resulted in finding methods for cost-effective large-scale production of the graphene as well as method for integrating into the

Expected results and effects

The project will result in improved competitiveness in SaltX current applications as well as open new product areas. This thanks to new production methods for the graphene and the graphene integration in salt-matrix as well as thanks to the improved performance that integration of the graphene has resulted in.

Planned approach and implementation

The graphene has been prepared and applied with a new method (patented) into the salt-matrix. This matrix has been analysed in a demonstrator where mass transport was investigated by SaltX. The resulting thermal conductivity improvement has been measured at Chalmers Industriteknik (CIT). A network of university and expertise has been built, Furthermore, knowledge of graphene production and surface application of the graphene has been developed which is the ground for industrial production of SaltX graphene-integrated matrix.
