India is taking substantial steps to bolster its domestic manufacturing capacity in the battery and electrolyser space to reduce import dependency, strengthen energy security, and meet decarbonisation goals. The high costs associated with imported systems, driven by transportation costs, import duties, and currency fluctuations, highlight the need for localised production. The government's policy initiatives, such as the production-linked incentive (PLI) scheme for advanced chemistry cell (ACC) battery storage, have spurred industry growth. Key players like Reliance, Ola Electric, and Tata Group are investing heavily in setting up battery manufacturing facilities. Strategic partnerships and collaborations further underline the industry's momentum, with companies like Hindustan Zinc Limited, JSW Group, and Waaree Energies Limited expanding their presence in the energy storage sector. Start-ups like Pointo and Lohum are also contributing to the sector's growth through funding and capacity expansions. Additionally, the focus on green hydrogen is driving the development of electrolyser manufacturing capabilities, supported by initiatives like the National Green Hydrogen Mission. The article outlines the significant progress and investments in both battery and electrolyser technologies, signaling a positive trajectory for India's energy storage and green hydrogen sectors.
