Renewable Hybrid Energy Systems Emerge as Viable Solution to Climate Change

Strategic Insights -

Researchers worldwide are exploring novel approaches to combat climate change, with a recent study highlighting the potential of renewable hybrid energy systems that integrate battery energy storage and hydrogen production technology. A team of researchers from the Department of Instrumentation and Control Engineering has designed an optimal renewable hybrid energy system (RHES) with battery storage and hydrogen production capability for powering rural communities in Bihar, India. The study examines three different battery energy storage systems, including Lithium-ion, Lead-acid, and Vanadium Flow, and concludes that a vanadium flow-based RHES is the optimal, sustainable, and feasible solution.
