Electrolysis is a possible method of producing carbon-free hydrogen from nuclear and renewable sources. Water is divided into hydrogen and oxygen through a process known as electrolysis. An electrolyzer is an apparatus in which this process occurs. The size of an electrolyzer can range from tiny, appliance-sized machinery ideal for small-scale dispersed hydrogen generation to large-scale, central production facilities that might be connected directly to renewable or other non-greenhouse gas-emitting types of power supply.

Water electrolysis is a well-known technique utilized in several industries, including the food business, the metallurgical industry, and power plants, among others. In addition, the water's components, which include hydrogen and oxygen, have several applications. For example, electrolysis-produced hydrogen provides a clean, renewable, and efficient fuel source. Water electrolysis primarily aims to produce pure hydrogen and oxygen gases.

Market Dynamics

Market Drivers

Increasing Use of Hydrogen in the Petroleum Refining Industry

Since modern petroleum refineries employ a tremendous amount of hydrogen in numerous processes, hydrogen has become an essential component of these sectors. The International Energy Agency (IEA) states that natural gas is the refineries' primary source for producing hydrogen, with methane used to create 75% of the necessary hydrogen. In addition, the cost of methane is considered the biggest bottleneck in the hydrogen generation process, which has encouraged companies to find other solutions for hydrogen production.

Hydrogen production is a crucial component of the refinery operation, so its demand is constantly increasing. The production of green hydrogen from large-scale electrolyzers at refineries is helping the companies meet growing hydrogen demand while reducing their carbon emission. As refineries are under increasing pressure to meet environmental legislation and reduce carbon emissions, it is expected that the refining industry will be one of the leading adopters of water electrolysis technology in the coming years, driving global market growth. 

Rising Demand for Green Fertilizers

Fertilizer production plants take hydrogen from natural gas or water and combine it with nitrogen from the air to make ammonia, which is further used to manufacture fertilizers for agricultural applications. For the fertilizer plant, hydrogen is produced using natural gas, and it causes greenhouse gas emissions, which have several adverse effects on the environment, including ozone depletion. Therefore, fertilizer companies are trying to reduce their emissions and move toward sustainable production, leading to a growing demand for green chemicals for fertilizer production.

Additionally, according to the American Chemical Society, in 2020, two Spanish companies, Fertiberia and Iberdrola, announced their plans to build Europe's largest plant for the generation of green hydrogen in Spain by the year 2027 for industrial applications such as fertilizer production and other applications. In this project, a green hydrogen production plant with a capacity of 720 metric tons per year will be set up next to Fertiberia's ammonia plant in Puertollano, Spain. The plant will also feature a 100MW photovoltaic solar plant to generate electricity to power electrolyzers for splitting water into oxygen and hydrogen. Fertiberia will then combine hydrogen with nitrogen to form ammonia to produce fertilizers. Fertiberia will also use electrolysis-generated oxygen as a raw material for nitric acid, which is also used for fertilizer production. Thus, the rise in demand for green fertilizers fuels market growth.

Market Restraint

Expensive Hydrogen Technology

The International Energy Agency (IEA) claims that several technical and economic factors, with energy prices and capital expenditures being the two most important, determine the price of hydrogen produced through water electrolysis. Therefore, the green hydrogen production cost depends on the cost of renewable energy and water electrolysis technology. Commercialized water electrolysis technology mainly consists of alkaline and proton exchange membrane water electrolysis technology. Among these, alkaline water electrolysis technologies contain low-pH electrolytes and corrosive electrodes.

In contrast, the proton exchange membrane electrolysis consists of costlier materials such as platinum, iridium, and many more, and it needs to be changed frequently. Therefore, the high prices of metals used in electrodes and catalysts coupled with other issues associated with water electrolyzers are the major challenge faced by the industry for the growth and wide adoption of water electrolysis technology across the globe.

Market Opportunities

Increasing Demand for Hydrogen Energy Storage

Renewable energy sources frequently experience supply and demand imbalances because they are most productive during low energy demand, creating a surplus of unused energy, and least productive during high electrical demand, creating energy shortages. Therefore, there is a growing demand for energy storage systems from renewable energy sources.

Hydrogen is considered an excellent option for energy storage. Hydrogen produced through electrolysis can be saved for later use as a variety of loosely bound hydride compounds, a compressed gas, or a cryogenic liquid. It can also be used in stationary fuel cells for power generation to power fuel cell vehicles, injected into natural gas pipelines to lower their carbon intensity, or any of several other applications. Therefore, with the application of hydrogen energy storage technology for renewable energy storage that is growing steadily, it is expected that it will present several lucrative opportunities for the growth of the water electrolysis market during the forecast period.
