Hindustan Petroleum Corporation (HPCL) will invest approx. Rs 20,000 crore (USD 231 million) over the next two to three years to establish 24 compressed biogas (CBG) plants across India, according to company officials. These plants will be implemented by HPCL Renewable and Green Energy, a dedicated subsidiary.

Two CBG plants have already been operationalised, and the remaining units will each produce 10–15 tonnes of biogas daily, using feedstocks such as agricultural waste, cattle dung, and sewage water. This initiative aligns with India's goal of increasing the share of gas in its energy mix from the current six percent to 15 percent by 2030. The move is also part of India’s broader efforts to reduce carbon emissions and achieve its net-zero target by 2070.

Since April 2025, the Indian government has mandated the blending of one percent CBG in fuel used for automobiles and cooking, a figure expected to rise to five percent by 2028–29. Vikas Singh, Director in the Union Oil Ministry, said India uses 28 million cubic mtrs. per day of gas for transport and cooking, a number expected to reach 44 mmscmd by 2028–29, supported by 480 upcoming CBG plants.
