Green hydrogen is the cleanest form of hydrogen available, as it is produced through water electrolysis using the electricity generated from renewable energy sources such as solar, wind, or hydropower. Carbon dioxide emissions are zero since no fossil fuels are used. Essentially, an electrolyzer is used in the electrolysis process to split water molecules into hydrogen and oxygen. The resulting hydrogen is refined by purification, compression, or liquefaction and then fed into various applications. Green hydrogen is considered a cornerstone of the global energy transition because it can store renewable energy, decarbonize hard-to-abate sectors, and serve as a sustainable alternative to fossil-fuel-based hydrogen.
Green hydrogen is destined to play a vital role in many industries due to its versatility as a fuel, feedstock, and energy carrier. In industry, it replaces grey hydrogen at refineries, in ammonia production, and in chemical production, decarbonizing fertilizers, petrochemicals, and synthetic fuels. The steel industry is increasingly adopting green hydrogen for DRI processes, replacing coal-based reductants and enabling near-zero-emission steel production. The green hydrogen finds its application in FCEVs, ranging from buses and trucks to trains and marine vessels, in the transport sector. Hydrogen fuel cells have longer ranges and faster refueling times compared to their battery-electric counterparts, making heavy-duty and long-distance applications viable. Green hydrogen can be further transformed into e-fuels, such as e-methanol or sustainable aviation fuel, supporting decarbonization in aviation and shipping.
Another major application is energy storage. Green hydrogen has the ability to store excess renewable energy for long periods of time, hence supporting grid stability, seasonal storage, and energy security. Hydrogen can be used in power generation by way of blending it with natural gas or using it directly in hydrogen turbines. Green ammonia production, which could act as a fertilizer, marine fuel, or even a hydrogen carrier, also uses green hydrogen. Being a clean molecule, green hydrogen enhances decarbonization efforts across industries, mobility systems, and energy networks.
The global green hydrogen market reached a value of USD 1.68 Billion in 2024. According to IMARC Group, the market is projected to reach USD 62.39 Billion by 2033, at a projected CAGR of 49.4% during 2025-2033. Structural changes within the energy sector are driving the global green hydrogen market, along with policy commitments, industrial decarbonization imperatives, and technology advances. Perhaps the most powerful of all drivers is the global drive for net-zero, as many countries implement hydrogen strategies and climate policies that offer a boost to renewable-based hydrogen production. Governments are offering subsidies, tax incentives, carbon pricing mechanisms, and funding for large-scale electrolyzer installations, making green hydrogen increasingly cost-competitive.
This rapid increase in renewable energy capacity-including solar and wind-gives plentiful supplies of the low-cost electricity required for producing green hydrogen. With falling renewable energy prices, the cost of producing green hydrogen falls, which enhances its attractiveness to industries looking at alternatives to fossil fuels. Another major driver is decarbonization of hard-to-abate sectors such as steelmaking, chemicals, refining, heavy transport, and aviation. These industries have specific demands for high-temperature heat or dense energy carriers that are not accessible through electrification; green hydrogen would fill in this gap.
Large-scale adoption is also being enabled by the development of the global hydrogen economy, comprising hydrogen pipelines, storage, refueling infrastructure, and port facilities. The investment of multinational corporations and industrial clusters in hydrogen hubs integrated with value chains is creating new markets and further accelerating commercialization.
Technological advances within electrolyzers-PEM, alkaline, and solid oxide technologies-continue to improve efficiency while reducing capital costs and are allowing for modular and scalable hydrogen production systems. Substantial investments in green ammonia, synthetic fuels, and hydrogen-based energy storage are increasing the number of possible end-uses. Furthermore, geopolitical initiatives to decrease dependence on fossil fuel imports and to diversify energy supplies enhance the strategic role of green hydrogen. All these drivers combined make green hydrogen a vital part of global decarbonization and a pivot towards a robust and sustainable energy system.
Objective
One of our clients reached out to us to conduct a feasibility study for setting up a medium scale green hydrogen production plant.
IMARC Approach: Comprehensive Financial Feasibility
We developed a comprehensive financial model for the setup and operation of a proposed green hydrogen production plant in India. This plant is designed to manufacture 300 tons of green hydrogen annually.
Production Process: The production process of green hydrogen is based on the generation of hydrogen by electrolysis of water, which takes place with electricity from renewable sources, such as solar or wind, hydropower, and geothermal. The process begins with the provision of renewable electricity, which is then channeled into an electrolyzer, an industrial device that splits water (H2O) into hydrogen (H2) and oxygen (O2). Water is purified before it enters the electrolyzer by filtration, demineralization, and reverse osmosis in order to remove impurities, which could damage components within the electrolyzers. Within the electrolyzer, electricity passes through electrodes separated by a membrane, thereby causing water molecules to dissociate. Each type of electrolyzer-alkaline, AEL; proton exchange membrane, PEM; or solid oxide electrolyzer, SOEC-specifies different operating conditions, depending also on efficiency. AEL systems use liquid electrolytes, PEM systems employ a polymer membrane for high-purity hydrogen, while the operation of SOEC is at high temperatures in order to enhance its energy efficiency. Oxygen is released at the anode during electrolysis and is vented or captured for industrial use, while hydrogen builds up at the cathode. The raw hydrogen gas is then fed through drying, purification, and compression steps to remove any moisture and residual oxygen to high purity for industrial, mobility, or energy storage applications. The generated pure hydrogen can be compressed or liquefied for easier transport either in its pure form or as a derivative in the form of green ammonia or methanol. Smart systems will include renewable energy forecasting, battery storage, and controls for the smart grid to optimize electrolyzer operation and maintain continuous hydrogen production. In sum, the production process emphasizes efficiency, purity, and sustainability; hydrogen is manufactured with no carbon emissions, ensuring it can serve as a clean energy carrier.
