India builds first ships powered by indigenous green hydrogen technology
India has embarked on a landmark project to construct its first indigenous green hydrogen-powered ships, marking a decisive step towards a cleaner and more sustainable maritime future. The initiative, being implemented at two of the nation’s leading shipyards, aims to showcase the potential of hydrogen fuel in reducing pollution across busy sea routes.
According to senior officials, each ship will be powered entirely by hydrogen fuel cells developed using indigenous technology. The move comes as part of the country’s broader ambition to transition away from fossil fuels in the shipping sector, one of the most significant contributors to marine pollution.
The government has allocated ₹115 crore under the National Green Hydrogen Mission for the current phase of the project, which runs until 2025–26. These funds will be directed towards vessel design, technology trials, port infrastructure upgrades, and pilot deployments. The plan is structured in two phases — the first focusing on retrofitting existing vessels to run on hydrogen, and the second on developing full-fledged hydrogen refuelling facilities at key ports. In line with this vision, major ports such as Deendayal, Paradip, and Tuticorin are being prepared as hydrogen hubs. One of these ports has already advanced plans for a 750-cubic-metre green methanol bunkering facility, laying the groundwork for future production and export capabilities. Officials emphasise that developing such hubs will not only meet domestic demand but also position India as a supplier in the emerging global hydrogen market.
Experts in the maritime sector believe that these pioneering vessels will significantly reduce greenhouse gas emissions and set a precedent for the region. By adopting indigenous hydrogen technology, the project also aims to build local expertise, cut import reliance, and generate high-value jobs in engineering and shipbuilding. Authorities highlight that the maritime shift to green hydrogen is central to meeting India’s climate commitments. Shipping accounts for a notable share of carbon emissions, and fuel innovations are vital to align with net zero goals. The green hydrogen approach offers a double advantage — its only by-product during operation is water, and it can be generated from renewable energy sources such as solar and wind.
Industry insiders note that while the transition will require sustained investment and rigorous safety standards, the long-term payoff in environmental benefits and energy independence is substantial. They stress that successful execution of these pilot ships could pave the way for larger fleets and potentially inspire similar moves in neighbouring countries. The project is being closely monitored as a benchmark for India’s technological readiness in the clean fuel space. If successful, it could anchor the country’s reputation as a leader in sustainable maritime innovation, setting the stage for greener trade corridors in the years ahead.
