The global electrolyser market size reached a value of about USD 461.85 million in 2023. The market is further estimated to grow at a CAGR of 27.30% in the forecast period of 2024-2032 to reach a value of around USD 4,054.68 million by 2032. This rapid growth is driven by the increasing demand for clean hydrogen production, a key player in the global transition to sustainable and renewable energy. As the world accelerates its efforts toward decarbonization, electrolysers—devices that use electricity to split water into hydrogen and oxygen—are emerging as a cornerstone of the green energy revolution.
Understanding the Electrolyser Market
The electrolyser market is primarily fueled by the growing global interest in hydrogen as a clean alternative to fossil fuels. As industries, governments, and organizations seek to reduce carbon emissions, hydrogen stands out due to its potential in decarbonizing sectors such as transportation, power generation, and industrial feedstock. Electrolysers play a pivotal role in this process by producing green hydrogen, which is essential for meeting the world’s increasing energy demands while reducing reliance on conventional energy sources.
Electrolysers can be categorized based on their technology, capacity, and application. The demand for hydrogen is anticipated to skyrocket over the next decade, which directly correlates to the growth of the electrolyser market. To better understand this market, let’s break it down into key segments.
Market Segmentation
By Product: Types of Electrolysers
The electrolyser market can be segmented into different types based on the technology used. Each type of electrolyser has unique benefits and is suited for specific applications.
- Alkaline Electrolyser
Alkaline electrolysers are one of the most widely used and cost-effective technologies in the market. These devices utilize a liquid alkaline solution, typically potassium hydroxide, as the electrolyte to produce hydrogen. Alkaline electrolysers are particularly beneficial in large-scale applications where efficiency is crucial. They are commonly used in industrial processes, such as hydrogen production for refineries and chemical industries. - Solid Oxide Electrolyser
Solid oxide electrolysers operate at high temperatures (around 800–1000°C) and are known for their high efficiency. They are typically used in large-scale applications, such as hydrogen production for power plants or high-temperature energy storage systems. These electrolysers can also play a significant role in reducing operational costs by leveraging waste heat from industrial processes. - PEM Electrolyser (Proton Exchange Membrane)
PEM electrolysers offer higher efficiency and compactness compared to alkaline systems. They are ideal for applications requiring high-purity hydrogen and are gaining traction in sectors such as transportation (fuel cell vehicles) and energy storage. Their ability to operate under variable renewable energy conditions (e.g., solar or wind) makes them highly attractive in the growing green hydrogen sector.
By Capacity: Scalability of Electrolysers
The capacity of electrolysers plays a crucial role in determining their use across different industries. Electrolyser systems are generally categorized based on the power they require.
- Less than 500 kW
Small-scale electrolysers are suitable for decentralized hydrogen production and smaller hydrogen applications. They are ideal for remote locations or where hydrogen is needed in limited quantities. Their use is expanding in residential applications, mobile energy solutions, and small-scale industrial processes. - 500 kW – 2 MW
Medium-capacity electrolysers are commonly used in industrial applications and commercial hydrogen production plants. They can support power generation, energy storage, and hydrogen fuel for vehicles and machinery. - Above 2 MW
Large-scale electrolysers are typically used in utility-scale projects or large industrial plants. These systems are essential for large-scale hydrogen production, enabling industries to scale up their decarbonization efforts. The significant capacity of these electrolysers makes them critical for meeting the global demand for clean hydrogen in sectors such as heavy industry, power generation, and transportation.
By Application: Key Sectors Using Electrolysers
Electrolysers are integral to several industries, offering versatile applications in energy, transportation, and manufacturing.
- Transportation
The transportation sector is one of the key drivers of the electrolyser market. With the growing shift toward hydrogen fuel cell vehicles (FCVs), electrolysers play a pivotal role in producing hydrogen for fueling these vehicles. They are also used in the production of hydrogen for heavy-duty trucks, buses, and trains, providing an alternative to traditional fossil fuel-powered vehicles. - Power Generation
Electrolysers help in integrating renewable energy into the power grid. They can store excess renewable energy as hydrogen, which can then be converted back into electricity when needed. This application is vital for addressing the intermittency of renewable sources such as wind and solar power. - Industry Feedstock
Hydrogen produced through electrolysis is increasingly being used as a feedstock in industrial processes, including in the production of ammonia for fertilizers, petroleum refining, and the production of steel. Electrolyser technology is essential for ensuring a sustainable supply of hydrogen in these industries, reducing reliance on fossil fuels. - Industry Energy
Electrolysers are also used in energy-intensive industries, such as steel manufacturing and chemicals production, to generate hydrogen for process heating and power generation. As industries look to decarbonize their operations, electrolysers are integral to achieving sustainable energy solutions.
