Tata Steel & Kraftblock Advance Successful Thermal Energy Storage Operations at Jamshedpur

Tata Steel, in partnership with Kraftblock GmbH, a German energy transition technology startup, is approaching a year of reliable operations of a thermal energy storage system at Sinter Plant #3 (SP3) at its Jamshedpur Works. The system is designed to recover high-temperature waste heat from the sintering process that would normally be released into the atmosphere, store it efficiently, and use it to warm process water required in the sintering stage. This simple shift is helping reduce fuel use, improve productivity, and lower carbon emissions by 22000 t-CO2 annually.

The pilot, which began a year ago, is now consistently delivering positive results and has become an important step in Tata Steel’s journey toward cleaner and more efficient steelmaking.

Chaitanya Bhanu, Vice President - Operations, Tata Steel Jamshedpur, said, “At Tata Steel, decarbonising steel production is closely linked to improving how efficiently we use energy across our operations. The Kraftblock thermal energy storage system demonstrates how high-temperature waste heat from an energy-intensive stage of steelmaking can be captured and reused within the process. The system demonstrates a practical and scalable pathway to more energy‑efficient steelmaking.

Dr. Martin Schichtel, CEO & Co-founder, Kraftblock, said, “The project at Tata Steel shows the great feasibility of heat recovery and storage in the steel industry. There are many use cases in steelmaking, from furnaces to flaring. With our sustainable Thermal Storages, we progress to support the steel industry in their efforts to become more energy- and cost-efficient”.
