Region : Global | Format: PDF | Report ID: FBI105436



The global alkaline water electrolysis market size was USD 100.47 million in 2020 and is projected to grow from USD 116.05 million in 2021 to USD 180.03 million in 2028 at a CAGR of 6.5% during the 2021-2028 period. The global impact of COVID-19 has been unprecedented and staggering, with alkaline water electrolysis witnessing a negative demand shock across all regions amid the pandemic. Based on our analysis, the global market exhibited a decline of -8.6% in 2020. The sudden rise in CAGR is attributable to this market’s demand and growth returning to pre-pandemic levels once the pandemic is over.

Alkaline water electrolysis is the process of converting water into oxygen and hydrogen. This process is widely used for hydrogen production, which finds its application in several industries, such as chemicals, petroleum, glass, refineries, automobile, pharmaceuticals, metals & mining, and others. The key market is anticipated to drive rapidly due to the growing demand for carbon-free sources of energy and an effective way of integrating renewables through the power to the gas facility.

COVID-19: Key Players Focus on Investment in Water Electrolysis Projects to Negate Sluggish Growth

The unexpected outbreak of COVID-19 has wreaked havoc on the global health system, affecting a wide range of industries. Several industrial projects may have been postponed as a result of the pandemic, causing substantial supply chain disruptions. Since January 2020, nearly every country in the world has seen a significant increase in the number of impacted cases. The global alkaline water electrolysis market has been slightly affected by the outbreak. However, the growing demand for renewable sources is anticipated to attract significant investments that will bode well for the market growth in the forthcoming years. For instance, in June 2020, ThyssenKrupp AG and De Nora expanded their manufacturing capacities for water electrolysis plants. This has enabled them to produce electrolysis cells with a total power consumption of one gigawatt annually.

Increasing Demand for Green Hydrogen to Propel Market Growth

Green hydrogen is gaining importance worldwide as an energy carrier and carbon dioxide-free feedstock for the electronics & photovoltaic, and green chemical industry. This has led to high demand for water electrolysis plants that can produce green hydrogen. Alkaline type of water electrolysis is developing as a key technology for building a carbon-free and flexible, sustainable energy system.

Several countries across the globe are currently planning to enter the green hydrogen economy. For instance, on October 20, 2020, the Western Australian (WA) government gave the Environmental Protection Authority (EPA) approval to the first stage of the Asian Renewable Energy Hub (AREH), a 15 GW hybrid solar and wind plant.  The project plans to eventually expand to 26 GW of solar and wind generation in a later stage, servicing industries throughout Australia and Asian markets with green hydrogen and ammonia. This factor is likely to drive the alkaline water electrolysis market growth.


Rising Government Regulations for Greenhouse Gas Emissions to Drive Market Growth

According to the World Economic Forum 2020, more than 120 countries have announced plans for net-zero emissions by 2050, including China, Japan, South Korea, South Africa, and Canada. Green hydrogen, manufactured by alkaline water electrolysis using solar and wind electricity, is essential for meeting international climate targets. In October 2018, United Nations Intergovernmental Panel on Climate Change (IPCC) declared that the world would have to reduce carbon dioxide emissions by 45% by 2030 and reach net zero by 2050. To ensure a global warming range between 1.5°C-2°C, more than 200 countries signed the Paris Agreement in 2015 that requires them to voluntarily and aggressively cut their carbon emissions. This factor is likely to drive the market during the global forecast period.

Increasing Demand in Transportation Sector to Augment Market Growth 

The increasing popularity of electric vehicles in Europe is likely to increase demand for alkaline water electrolysis. In addition, countries like China, Japan, and South Korea have suggested major electric car implementation pledges in order to lessen the world's rising reliance on fossil fuels. In the next few years, this is projected to contribute to the market's growth.

Electric vehicles play a critical role in meeting the sustainable development scenario to reduce gas emissions and address climate change. Green hydrogen is clean energy carrier fuel. According to the International Energy Agency (IEA), the global electric vehicle market grows by 36% annually, reaching 245 million vehicles in 2030. This factor is likely to drive the market growth during the forecast period.


High Hydrogen Cost to Impede Market Growth

Alkaline water electrolysis is widely used to produce green hydrogen, but it faces more challenges due to its high cost. Green hydrogen produced from the plant is two to three times more expensive than grey hydrogen. According to the International Renewable Energy (IRENA) - Green Hydrogen Economy Report 2019, electric vehicles with fuel cells and hydrogen tanks cost at least 1.5 to 2 times more than their fossil fuel counterparts. However, key players such as ThyssenKrupp AG are developing prefabricated skid-mounted modules for water electrolysis plants, which helps to keep costs down. The units are easy to transport and can be combined to realize projects of megawatts or gigawatts, which will likely drive the market during the forecast period.


By Type Analysis

≥80 m3/h Electrolysis Segment Accounted for Largest Market Share

Based on the type, the market is categorized into <10 m3/h, <30 m3/h, <50 m3/h, <80 m3/h, and ≥80 m3/h.

The ≥80 m3/h segments accounted for the major share of the market in 2020. Large-scale systems frequently use these types of equipment. Because cheaper nickel-based catalysts are used, this technology has a lower initial cost and a longer shelf life.

The <10 m3/h, <30 m3/h, <50 m3/h electrolysis plants are mainly used for small-scale hydrogen production. High differential pressures across the membrane are used in these devices.
