Water Electrolysis Market Trends



  • Increasing demand for environment-friendly technologies to boost the market growth


Hydrogen has become a critical vector for a wide range of applications in the future in light of climate change and the increasing demand for environmental sustainability. Innovations and technological advancements have primarily focused on producing hydrogen in a sustainable and environment-friendly manner in response to the growing interest in hydrogen. During the forecast period, governments increasingly support renewable chemical technology while private investment is soaring. As a result of the Sustainable Development Program, published by the United Nations in 2015, and similar programs, the water electrolysis machine market is likely to continue to grow.


Over the past few decades, electrolysis of water has gained considerable popularity, and this trend is expected to continue. As environmental protection and pollution levels continue to be regulated in various parts of the world, water electrolysis machines are expected to grow steadily shortly due to the regulatory environment supporting the emerging technological ecosystem. For instance, researchers at the National University of Ireland Galway and Technical University Berlin researched the recent catalyst and material developments.


The increasing demand for sustainable farming practices has led to a increase in the popularity of green fertilizers. The usual ammonia method uses Steam Methane Reforming (SMR) to produce hydrogen, while the Haber process produces a significant amount of carbon dioxide. Around 90% of the carbon dioxide produced by SMR is released into the atmosphere, leading to significant warming. Ammonia production processes that emit less CO2 and are sustainable have increased demand. Therefore, such factors related to electrolysis of water efficiency have recently enhanced the water electrolysis market CAGR.


However, it is anticipated that water electrolysis machines will shortly remain crucial to the steel and pharmaceutical application market. The chemical, power, and petroleum sectors are gaining traction with electrolysis water, and all these are other factors driving the growth of the water electrolysis market revenue.


Water Electrolysis Market Segment Insights


Water Electrolysis Product Category Insights


The water electrolysis market segmentation, based on product category, includes proton exchange membrane, alkaline water electrolysis, and solid oxide electrolyte (SOE). The proton exchange membrane electrolysis system segment held the majority share in 2021, contributing to around ~35-37% with respect to the water electrolysis market revenue. The production of PEM electrolyzers is highly energy-efficient and requires a high-purity hydrogen source. Cell stack manufacturing methods generate the majority of costs and energy used in producing PEM electrolyzers. There are a number of advantages to PEM water electrolysis systems over the other two methods, including higher hydrogen production rates, a more compact design, and better energy efficiency.


Water Electrolysis End Users Insights


The water electrolysis market segmentation, based on end users, includes chemicals, electronics & semiconductors, power plants, petroleum, pharmaceuticals, and others. The chemicals segment dominated the market in 2021 and is projected to be the faster-growing segment during the forecast period, 2022-2030. The increasing adoption of water electrolysis machines in the chemical industry results from extensive hydrogen generation requirements in the production of ammonia fertilizers, iron ore reductions, and methanol, as well as fuel additives and fuel cell developments. Moreover, the petroleum industry is another major application area for water electrolysis machines. In large-scale plants that conventionally use hydrocarbon fuels and natural gas for their hydrogen needs, water electrolysis technologies have been adopted as an alternative to hydrocarbon fuels and natural gas for hydrogen applications in crude oil processing and refining. Which positively impacts the electrolysis of water market growth.

Water Electrolysis Regional Insights


By Region, the study provides market insights into North America, Europe, Asia-Pacific and the Rest of the World. The Asia-Pacific water electrolysis market accounted for USD 2,677.7 million in 2021 and is expected to exhibit a significant CAGR growth during the study period. Government investments in hydrogen-fueled vehicles and the growing demand for green fertilizers have led the Chinese government to announce its first-ever long-term hydrogen vehicle plan in March 2022. As  hydrogen fuel-cell vehicles have more condensed energy storage, they can go farther than electric vehicles, so the government wants 50,000 vehicles on the roads by 2025.


Further, the major countries studied in the electrolysis of water market report are: The U.S., Canada, Germany, France, the UK, Italy, Spain, China, Japan, India, Australia, South Korea, and Brazil.
