Evaluating Energy Storage Solutions for 24/7 Renewable Energy Security

Evaluating various energy storage devices for 24*7 energy security from renewables

Objective

• In this project, a test rig will be developed to study batteries under different renewable generation profiles with/without grid support and load consumption profiles (eg. commercial complexes, industries). The test rig will be used to test lithium-ion batteries (LFP, NMC), sodium-ion batteries (depending on the availability), lead-acid batteries, and electrolyzer/fuel cell combination.

Description

• India's energy consumption is expected to grow at a rate of 4.5 % per year (on average) for next 25 years. As majority of this energy requirement is expected to come from renewables, we would need huge energy storage to avoid the curtailment and fill the deficit, Considering the potential of different energy storage devices and their cost, it is essential to identify the readiness of batteries for integration to renewables, The response and readiness of different energy storage devices to a given generation/consumption profile will be studied.

Impact

• This proposal is made to test the energy storage devices at any generation profile, energy sources (AC/DC), and load profiles. The outcome is expected to be at TRL5.
