TDB‑DST Funds Indigenous Energy Storage Technologies for Bio‑Waste Hard Carbon in Sodium‑Ion Batteries

The Technology Development Board, under the DST, has funded Indigenous Energy Storage Technologies Pvt. Ltd. to commercialise hard carbon anodes derived from agricultural waste for sodium‑ion batteries. The move aims to build a domestic, sustainable battery supply chain, reduce import dependence on lithium, and support India’s self‑reliant clean‑energy transition.

Technology Development Board backs indigenous hard‑carbon production for sodium‑ion batteries Overview The TDB of the DST has approved funding for Indigenous Energy Storage Technologies Private Limited (Roorkee, Uttarakhand). The project, titled “Commercialisation of Bio‑waste / Agricultural Waste Derived Hard Carbon for Sodium‑Ion Batteries”, aims to set up commercial‑scale production of hard carbon anodes sourced from agricultural residues. Key Developments Financial assistance extended to enable large‑scale synthesis of hard carbon from bio‑waste. Targeted applications: grid‑scale storage, UPS/inverter systems, solar street lighting, and low‑speed electric mobility (e‑rickshaws, e‑scooters, e‑cycles). Hard carbon offers high initial coulombic efficiency, stable cycling and better energy density for SIBs . Utilises locally available agricultural and bio‑waste, reducing dependence on imported lithium and graphite. Project aligns with India’s push for a self‑reliant battery ecosystem under the Atmanirbhar Bharat strategy. Important Facts Hard carbon retains a disordered microstructure and porosity at high temperatures, making it suitable for sodium‑ion chemistry unlike graphite. Bio‑waste derived precursors provide a circular‑economy route, turning agricultural residues into high‑value battery material. Sodium and carbon are abundant and geographically dispersed, mitigating global supply‑chain risks associated with lithium. Project spokesperson Shri Rajesh Kumar Pathak , Secretary, TDB, highlighted the role of waste‑to‑value technologies in building a resilient battery ecosystem. UPSC Relevance The initiative touches upon several GS topics: energy storage and the shift from lithium‑ion to sodium‑ion systems; circular‑economy practices in material manufacturing; and the role of public funding agencies like TDB in fostering indigenous innovation, a key aspect of the self‑reliance agenda. Way Forward Scale‑up pilot plants to achieve commercial viability and cost competitiveness with imported anodes. Encourage collaborations between research institutes, start‑ups and established battery manufacturers. Formulate standards and certification for bio‑waste derived hard carbon to ensure performance consistency. Integrate the technology into national renewable‑energy programmes such as the Solar Mission and grid‑storage schemes.
