ACME–IHI Joint Venture Advances India’s Largest Green Ammonia Project in Odisha

ACME Group and Japan’s IHI Corporation are jointly developing India’s largest green ammonia project in Gopalpur, Odisha, marking a milestone in the India-Japan Clean Energy Partnership. IHI has acquired a 30% stake in ACME Clean Energy, while ACME retains 70%. With land acquisition complete and the Front-End Engineering Design (FEED) finalized, the project is now moving into detailed development.

The initiative was highlighted at the 15th Japan-India Annual Summit (Tokyo, August 2025), where Prime Ministers Narendra Modi and Shigeru Ishiba adopted a Joint Declaration of Intent on Clean Hydrogen and Ammonia. The project aligns with India’s National Green Hydrogen Mission, reinforcing India’s role as a global producer of green hydrogen and derivatives, while securing Japan’s long-term supply of clean fuels to decarbonize power generation and industry.

The Gopalpur facility will produce 0.4 million tonnes of green ammonia annually and mitigate 0.8 million tonnes of CO? emissions per year. Exports will primarily serve Japanese industries in power and chemicals, strengthening bilateral energy ties. The project represents one of the largest foreign collaborations in India’s green ammonia sector, with funding sourced from Japanese export credit agencies (ECAs), international lenders, and partner equity.

Strategically located on India’s eastern seaboard, Odisha offers port access, government support, and natural resources, making it a hub for green ammonia exports. Beyond energy benefits, the project is expected to drive industrial investment, employment, and skill development in the state.

According to ACME Chairman Manoj Kumar Upadhyay, the venture is a “milestone for India’s global green hydrogen leadership,” while IHI CEO Hiroshi Ide emphasized its role in securing a sustainable green ammonia value chain. The plant is slated for commissioning by 2029–30, with production earmarked for exports to Japan.
