AM Green and the VOC Port Authority plan to develop a green ammonia marine bunkering hub in Thoothukudi, Tamil Nadu. The project includes investments in both production and bunkering infrastructure, with total planned investment described as over ₹22,000 crore for setting up the production and related bunkering facilities. Separately, the partners outline a bunkering capacity target of up to 200 KTPA (kilotonnes per annum) for green ammonia by 2029–30. The bunkering hub is reported to require an estimated investment of about ₹2,000 crore, reflecting a focus on the port-side infrastructure needed to supply ammonia to vessels. The sources describe the initiative as a partnership aimed at enabling marine bunkering of green ammonia, aligning production activities with port operations. Overall, the reporting indicates a phased development through the late 2020s to reach the stated bunkering capacity, backed by large upstream and downstream investment plans. No details on financing structure, timeline milestones before 2029–30, or specific regulatory approvals are provided in the excerpts.
