Market Definition and Introduction
The global hydrogen production equipment by electrolysis of water market was valued at USD 6.67 billion in 2024 and is anticipated to reach USD 15.87 billion by 2035, expanding at a CAGR of 8.2% during the forecast period (2025–2035). As industries and utilities pursue decarbonization, electrolytic hydrogen produced in renewable-powered electrolysers has become a linchpin in the decarbonised energy and feedstocks value chain. Equipment manufacturers are scaling up both proton exchange membrane and alkaline electrolysis systems from megawatt-scale pilot projects to the multi-megawatt commercial implementation of green-hydrogen production for chemicals synthesis, ammonia, methanol, and grid-balancing applications.
PEM technology, with an advantage for rapid dynamic response and high-purity output, is witnessing growing investments from power-plant integrators using Electrolysers in synergy with wind and solar projects to absorb surplus generation. Alkaline electrolysis, on the other hand, will keep holding its ground with the prospect of a mature production base at lower capital costs per unit towards fulfilling that promise for chemical plants with bulk shifts of hydrogen. When coupled with advancements in Electrolyser stack durability paired with decreasing renewable power costs, the electrolytic routes are gradually displacing the grey-hydrogen pathways as critical drivers for industrial decarbonization roadmaps.
Equipment lifecycle services offered together with hardware to lower the overall cost of ownership and ensure uptime will continue to encompass commissioning, stack replacement, and digital performance monitoring. Partnership collaborations between renewable developers, heavy-industry off-takers, and OEMs will provide the acceleration stream for gigawatt-scale Electrolyser deployments, creating new supply chains and training programs. With this transition from pilot to industrial scale, hydrogen production economics are being redefined, creating the infrastructure backbone for the global green-hydrogen economy.

Market Dynamics

Technological Advancements Driving Efficiency and Cost Optimisation in Electrolysis Systems
Dramatic improvements in efficiency and system longevity, and such integration with variable-renewable sources can be observed due to the rapid evolution of electrolyser technologies. Manufacturers are developing improved catalysts and membranes that lower the energy consumption per kilogram of hydrogen produced. The development of modular, stackable electrolyser systems has enhanced flexibility, allowing for distributed generation in an off-grid or hybrid configuration. The declining cost of electrolyser stacks as economies of scale continue to develop will further close the price differential between green and grey hydrogen production, eventually establishing electrolysis as a pillar of the upcoming clean energy infrastructure.
Capital Intensity and High Electricity Costs Pose Persistent Challenges
Electrolysis is, however, capital-intensive and predominantly reliant on renewable electricity that must also be cheap. For most small to midscale operators, the high capital cost of the construction of the electrolyser units, along with their installation and balance-of-plant support systems, becomes an important deterrent. In addition, the economics of hydrogen production are influenced by the tariffs on electricity and fluctuations in renewable generation. To counter such concerns, different innovative financing models, power purchase agreements (PPAs), and government-backed subsidy initiatives are being encouraged to enhance the creditworthiness of the respective projects.
Policy Support and Net-Zero Commitments Create Favourable Market Opportunities
Governments across the globe keep announcing ambitious hydrogen strategies that will spur demand for water electrolysis equipment. Hydrogen roadmaps from the EU, Japan, South Korea, and Australia lay down plans for extensive funding for electrolyser deployment and infrastructure buildout. The inclusion of hydrogen in carbon reduction schemes, coupled with renewable energy credit schemes, greatly enhances commercial viability. Electrolysis is being applied across various industries, refining, chemicals, mobility, and grid balancing their decarbonisation endeavours, thus opening a wide array of opportunities for the manufacturers and service providers.
Emergence of Hybrid Electrolysis Systems Reflects Industry’s Trend Toward Integration
Among the emerging trends shaping the market, hybridisation of electrolysers with renewable power generation, energy storage technologies, and grid management will be one of the most defining. These hybrid systems that combine solar and wind with hydrogen storage will provide stable operation despite the intermittency of renewables. Adding a smart grid allows for assisted reliability with predictive maintenance tools, enhancing uptime. These integrated systems can be very compelling to remote and island economies in search of autonomous, sustainable energy generation modes.
Supply Chain Constraints and Skilled Workforce Shortages Restrict Rapid Scaling
The increased demand for hydrogen production equipment has revealed bottlenecks in the whole supply chain, such as sourcing rare materials like iridium for PEM electrolysers. Supply of equipment is restricted in some regions, while the availability of skilled technicians and hydrogen safety experts is definitely well behind current industry needs. Profiles for urgently training the workforce needed to address this shortage will be important in establishing regional manufacturing clusters that, in turn, can sustain market momentum over a long period.

Dominating Segments

PEM Electrolyser System: Top-Notch Energy Systems with Optimal Efficiency and Renewability
The dynamics of a Proton Exchange Membrane (PEM) electrolyser are truly compelling because they are small, high current density, and can operate dynamically with variable renewable energy inputs. PEMs are ideal for solar and wind projects because of their rapid response to inputs and ability to balance the load quickly. Therefore, PEM electrolysis systems are preferred in this project, with increasing demand for decentralised hydrogen generation requiring high purity for transportation and chemical end users. With the advent of global investments in recovering and recycling iridium, material cost constraints have become less of an impediment, and this has led to wider adoptability for large-scale projects.
Alkaline Electrolysers, Traditionally in Use, Now Threatened by Truthful Costs, Work Maintained
Alkaline electrolysers have historically dominated the market for large-scale hydrogen generation due to their robust design and relatively lower capital costs. Traditionally applied in fertiliser and chemical production, they are now being upgraded with advanced electrodes and better membrane materials to improve efficiency. Capacity factors are high and degradation is minimal; hence they are well suited to continuous large-scale hydrogen production systems. Still being used in many refineries and petrochemical applications, the alkaline systems will ensure this segment's market share remains stable through the year 2035 simply because of their operational simplicity and cost-effectiveness.
Power Generation Sector, Slow and Fastest-Growing Customer Segment by Electrolysis
Power producers are cognizant of hydrogen as a fuel and a storage medium in the global energy transition. Electrolysis converts electricity from renewable energy sources for storage by stabilising grids for excess electricity, which can later be converted to power through fuels or hydrogen turbines. In Europe, Japan, and Australia, life cycle tests on hydrogen co-firing in gas turbines exemplify the importance of electrolysers to the decarbonisation of electricity generation. As world nations modernise their electricity infrastructure towards agile, renewables-integrated grids, hydrogen electrolysis will see an explosive increase in this sector.
