DEVISE will develop a comprehensive storage system that enables efficient and rational end use of all forms of energy by having a heterogeneous storage facility for diverse forms of energy and to facilitate conversion from one form to another for optimal catering of diverse loads. A holistic approach ensures efficient integration/ Transformation of different forms of energy for rational end-use and storage of all forms of renewable energy to facilitate the optimal interchange. The developed energy bank will be demonstrated for typical demand-supply scenarios in India that will also lead to developing a decision support system for planning in EU and India.

The project aims to develop a strategy that optimally chooses efficient storage in real-time based on the available energy form and load demand. This optimal selection will reduce the redundant energy conversion losses and thereby increasing the efficiency of the system The project proposes an energy-bank (EB), designed to store energy in diverse forms, and based on the availability and demand of energy within the system. the project integrates the thermal sources directly with the thermal loads and to meet the intermittency in these sources. The system allows the integration of various vectors for electrical storage and thermal storage depending upon the demand and supply characteristics. Electrical battery banks, thermal batteries, phase-changing material and the biogas energy using balloons/cylinders (hydrogen/methane) are integrated into the EB.
