V.O. Chidambaranar Port in Tuticorin, India, under the Ministry of Ports, Shipping & Waterways, is making significant strides in the adoption of renewable energy, particularly focusing on green hydrogen production. The Ministry aims for major ports in India to have a 60% share of renewable energy consumption by 2030 to reduce carbon emissions. The process of electrolysis using electricity from renewable sources like solar and wind results in the production of green hydrogen, a clean and emission-free fuel with the potential to replace fossil fuels. The Ministry of Shipping and Ports has designated V.O. Chidambaranar Port, along with two other major ports, as nodal ports for developing hydrogen hubs capable of handling, storing, and producing green hydrogen. This aligns with the objectives of the National Green Hydrogen Mission, seeking to utilize hydrogen in various industrial sectors. Challenges such as water availability are being addressed through initiatives like establishing a desalination plant, while collaborations with renewable energy firms are driving the development of green hydrogen projects within the port area. The port has also embraced green hydrogen for its operations, including utilizing hydrogen fuel cells for port crafts and cargo handling equipment to reduce emissions. The launch of a hydrogen fuel cell ferry and plans to convert ships and tugs to run on green hydrogen demonstrate the port's commitment to sustainability and innovation. With strategic partnerships and initiatives, V.O. Chidambaranar Port is paving the way for India's clean energy transition, positioning itself as a pioneer in the green hydrogen revolution.
