State-run Oil and Natural Gas Corporation (ONGC) in India, responsible for a significant portion of the country's oil and gas production, is actively diversifying its business strategy to embrace renewable energy and sustainable technologies. The company plans to venture into imported LNG, green hydrogen, compressed biogas, battery storage, and even nuclear energy as part of its efforts to achieve net-zero emissions by 2038. With challenges like declining crude oil production and global shifts away from fossil fuels, ONGC aims to secure its relevance and India's energy security in a rapidly changing energy landscape. ONGC's LNG import plans and investments in renewable energy aim to bridge the gap between domestic production and demand, with a focus on increasing India's natural gas share in the energy mix. The company's initiatives also include establishing a 2 mtpa green ammonia plant, exploring small modular reactors (SMRs) for nuclear power, and setting up compressed biogas plants. ONGC's move towards green hydrogen production and battery storage signifies a proactive approach to sustainability and decarbonisation. The company's establishment of subsidiary ONGC Green and acquisition of Ayana Renewable Power showcase its commitment to greener energy solutions. ONGC's strategy aligns with global trends observed in major oil producers transitioning towards renewables. The efforts made by ONGC reflect a positive outlook for India's energy landscape, emphasizing sustainability, innovation, and a diversified energy mix for the future.
