Notably, BHEL has already entered into a Strategic Tie-up with thyssenkrupp nucera India Private Limited for alkaline electrolyser systems in July 2026. This collaboration with Hystar for PEM electrolyser systems further strengthens BHEL’s position as one of the few Indian players capable of offering both alkaline and PEM electrolyser solutions to serve the country’s emerging green hydrogen market. Moreover, the collaboration will also strengthen BHEL’s project execution capabilities for green hydrogen projects in India. This will also enhance BHEL's contribution to National Green Hydrogen Mission and support the Government of India's Make in India initiative.</in-capmkt:RationaleAndExpectedBenefitOfArrangement></xbrli:xbrl>
