As the world transitions towards clean energy, the role of Engineering, Procurement, and Construction (EPC) companies in shaping sustainable infrastructure, particularly in emerging markets, becomes increasingly important. Green hydrogen and renewable energy projects are at the forefront of this transition, offering opportunities for firms to create new business models and revenue streams while contributing to a low-carbon future. EPC companies are pivotal in driving the development of hydrogen value chains by designing and constructing essential infrastructure such as electrolyzer plants, storage facilities, and refueling stations. Their expertise enables the integration of hydrogen production with renewable energy sources, improving energy efficiency and supporting local industries. The article highlights India's National Green Hydrogen Mission, emphasizing the country's efforts to increase green hydrogen production, infrastructure, and exports in sectors like fertilizers and heavy industry. EPC companies can leverage renewable resources and industrial demand to attract investors and develop hybrid projects that combine hydrogen production with other renewable outputs. To overcome funding challenges, a combination of international loans, private investments, and risk-sharing models is crucial for the success of green hydrogen projects in emerging markets. Standardization of designs for electrolyzers and plant components is identified as a key strategy to reduce costs, accelerate deployment, and enhance investor appeal. Mitigating risks associated with clean energy projects, especially those involving new technologies like green hydrogen, involves technology partnerships, phased commissioning, and digital simulations to optimize operational performance. By integrating infrastructure expertise with innovative financial and project delivery models, firms can play a significant role in the global clean energy transition.
