Demand – Drivers, Challenges, and Opportunities

Market Demand Drivers: Shift toward Renewable Energy Integration
Renewable energy sources are gaining attention in the market to adhere to a more sustainable future. Green hydrogen produced from renewable energy is increasingly being utilized for various applications such as oil and gas, industrial feedstock, and as a fuel in energy generation industries. Several renewable energy sources will be integrated with technical and material technologies to save and store energy in the coming years. Green hydrogen is produced from renewable energy sources, such as solar, hydro, and wind.

According to International Renewable Energy Agency (IRENA), annual capacity addition for onshore wind power is expected to increase more than threefold by 2030 and more than tenfold by 2050 relative to 2018 levels. The shift toward renewable energy transition is expected to have a direct impact on driving the adoption of water electrolysis for hydrogen production.

Furthermore, sustainable production and the use of carbon-free products on a priority basis could attenuate the problem of rising carbon emissions. Consumers prefer green hydrogen over hydrogen produced from conventional methods, as it promotes the decarbonization of power and mobility industries. Several end-use industries are moving toward green hydrogen due to its zero-carbon emission ability. Numerous interesting studies have been conducted on green hydrogen manufacturing technology and its use. Thus, consumer awareness widens the scope for sustainable products, which is expected to drive the growth of the global power supply equipment market for water electrolysis during the forecast period.

Market Challenges: High Energy Losses during the Electrolysis Process
Green hydrogen offers a decarbonization solution to the industrial, chemical, and transportation sectors; however, there is a considerable amount of energy loss during green hydrogen production at every point in the supply chain. According to the World Economic Forum, more than 30% of the energy used in hydrogen production is lost during the electrolysis process. The water electrolysis technology is majorly used for hydrogen production, and alkaline water electrolyzers offer a range of 50-78% energy efficiency, while the proton exchange membrane water electrolyzers offer an energy efficiency between 50-80%.

The World Economic Forum (WEF) further states that liquefying or converting hydrogen to other carriers, such as ammonia, results in a further 13-25% energy loss, and transporting hydrogen requires additional energy inputs that are typically equal to 10-12% of the hydrogen’s energy.

Also, the use of hydrogen in fuel cells results in an additional 40-50% energy loss. Therefore, the net energy loss in hydrogen production using water electrolysis technology and in its further application processes is a major challenge for hydrogen production using water electrolysis technology. This is expected to restrict the growth of power supply equipment during the forecast period.

Market Opportunities: Advancements in Electrolysis Technology
Green Hydrogen has been widely considered an ideal sustainable energy based on the advantage of high conversion efficiency, abundant reserves, zero pollution, and high energy density. It is crucial to develop a more cost-effective green hydrogen production/water electrolysis system to achieve the goal of reducing the energy consumption of water splitting. The proton exchange membrane electrolyzer technology holds core material technology and uses expensive noble metal-based catalysts and perfluorocarbon-based proton exchange membranes, which results in high costs of system manufacturing. In order to address the limitations associated with conventional technology, a research team in Korea has recently made advancements in the development of a next-generation water electrolysis system. This breakthrough technology offers significant improvements in durability and performance, along with a substantial reduction in the cost of producing green hydrogen energy. The Korea Institute of Science and Technology has announced this project, which is the result of joint research conducted by Dr. So Young Lee’s team at the Center for Hydrogen and Fuel Cell Research and Prof. Young Moo Lee from the Department of Energy Engineering at Hanyang University. The team successfully developed a membrane electrode assembly for anion exchange membrane water electrolyzers, which holds promise for replacing the expensive existing PEM technology.

Moreover, an improved understanding of the nanoscale processes occurring in SOECs is expected to result in performance and lifetime gains on the cell, stack, and system levels, which in turn enable more sizable and highly efficient SOEC plants. In Germany, the proportion of intermittent renewable energy sources in the electricity supply has exceeded 30%, while in Denmark, intermittent sources account for nearly 50% of the electricity supply. As more countries experience this shift, there will be a growing demand for energy conversion technologies that are highly efficient, such as SOECs. These cells present an opportunity to reduce the costs associated with future renewable energy systems through enhanced conversion efficiency, enabling greater integration of renewables into the energy mix. Consequently, this creates opportunities for power supply equipment suppliers.

Moreover, a recent advancement in water-splitting technology known as hybrid water electrolysis has emerged. This innovative system leverages the thermodynamically more favorable electrochemical oxidation of organic molecules instead of traditional oxygen evolution reactions (OER). By coupling this approach with hydrogen evolution reactions (HER), the hybrid water electrolysis system enhances the efficiency of water electrolysis and promotes more efficient production of hydrogen. This strategy avoids the generation of unnecessary O2 and provides the production of value-added chemicals with large current density at low input voltages, thereby improving energy conversion efficiency. With such development in electrolysis, the demand for power supply equipment is also anticipated to gain traction during the forecast period.
