The Impact of Production Linked Incentives (PLI) on Growth
The primary driver for the expansion of electrolyser manufacturing in India has been the government’s targeted fiscal support through the Production Linked Incentive (PLI) scheme. By offering financial incentives based on the capacity and efficiency of the manufactured units, the government has successfully attracted both domestic industrial giants and global technology leaders to set up shop in India. This scheme provides the necessary “cushion” for manufacturers to scale their operations and invest in state-of-the-art facilities. The competition fostered by the PLI scheme is also driving technological maturation, as companies strive to produce the most efficient and cost-effective electrolysers to qualify for the highest incentive brackets. This policy-led approach has effectively jump-started a sector that would have otherwise taken years to gain momentum.
Diversification of Electrolysis Technologies: Alkaline, PEM, and SOEC
The growth of electrolyser manufacturing in India is not limited to a single technology but encompasses a diverse range of electrolysis methods. Alkaline electrolysers, known for their maturity and relatively lower cost, are currently the mainstay of the industry. However, there is a growing focus on Proton Exchange Membrane (PEM) technology, which offers better flexibility and integration with intermittent renewable energy sources. Additionally, high-temperature Solid Oxide Electrolyser Cell (SOEC) technology is being explored for its superior efficiency, particularly in industrial settings where waste heat can be utilized. By fostering a manufacturing base that supports all these technologies, India is ensuring that its industrial sector has access to the best tools for specific applications, whether it be large-scale ammonia production or decentralized hydrogen refuelling.
Building a Resilient Ancillary Supply Chain for Components
A truly successful sector for electrolyser manufacturing in India requires more than just final assembly plants it demands a deep and resilient ancillary supply chain. Each electrolyser unit is composed of thousands of precision-engineered parts, many of which require specialized materials like iridium, platinum, and high-performance polymers. Encouraging domestic small and medium enterprises (SMEs) to specialize in these components is vital for creating a sustainable ecosystem. This includes the manufacturing of power electronics, cooling systems, and water treatment modules. By integrating these suppliers into the larger manufacturing framework, India can minimize bottlenecks and ensure that the benefits of the hydrogen economy are distributed throughout the entire industrial landscape, creating a multiplier effect for job creation and economic growth.
Technological Innovation and R&D for Efficiency Gains
To maintain a competitive edge, electrolyser manufacturing in India must be underpinned by continuous research and development. The goal is to produce units that offer higher current densities, lower degradation rates, and reduced use of expensive rare earth metals.

While the manufacturing capacity is scaling, the industry must also address the logistical challenges of moving these large, sensitive units from factories to project sites. The transport of multi-megawatt electrolyser modules requires specialized heavy-lift logistics and a robust road and port infrastructure. Furthermore, the installation of these units requires a skilled workforce capable of handling high-pressure gas systems and complex electrical integrations. By investing in vocational training and improving industrial logistics, India can ensure that the rapid growth in manufacturing capacity is matched by a smooth deployment phase. This holistic approach ensures that the electrolyser manufacturing in India contributes to a seamless and efficient transition toward a green energy future.
