India and Japan strengthen green energy ties with biogas CNG and methane plant expansion

This would be a big step towards sustainable mobility and improved energy security.

June 25, 2026. A new framework to encourage biogas-powered compressed natural gas (CNG) vehicles is about to be established by India and Japan, solidifying their clean energy relationship. This would be a big step towards sustainable mobility and improved energy security.

During the forthcoming three-day visit of Japanese Prime Minister Sanae Takaichi to India, the two nations are reportedly slated to issue a memorandum of understanding, as reported in The Japan Times. The primary goal of the agreement is to increase the production and use of biogas, a transportation fuel derived from methane.

The two countries intend to work together to expand India’s methane production capacity to over 1,000 plants. Fermenting cow manure at these facilities will produce methane, which can be further processed into compressed biogas and utilised as fuel for CNG-powered vehicles.

This project bolsters the joint endeavours of the two nations to lessen their reliance on traditional fossil fuels and hasten the shift to cleaner modes of transportation.

The largest player in India’s passenger vehicle sector, Suzuki Motor Corporation, would be a crucial ally in the endeavour. The biogas generation projects in India have already been begun by the Japanese vehicle maker with financial aid from Japan’s Global South support program.
