Electrolyzer Market

An electrolyzer is an equipment that breaks down water into hydrogen and oxygen through the process of electrolysis. An anode, a membrane, and a cathode make up the electrolyzers. On the cathode side, hydrogen is gathered and then stored for usage in a variety of industries. Either oxygen is gathered and employed in additional industrial operations, or it is discharged into the atmosphere.

Electrolysis capacity for dedicated hydrogen production has been growing in the past few years, however, the pace slowed down in 2022 with about 130 MW of new capacity entering operation, 45% less than the previous year. However, electrolyzer manufacturing capacity increased by more than 25% since 2021, reaching nearly 11 GW per year in 2022. The realization of all the projects in the pipeline could lead to an installed electrolyzer capacity of 170-365 GW by 2030. Electrolysis capacity is growing from a low base and requires a significant acceleration to get on track with the Net Zero Emissions by 2050 (NZE) Scenario, which requires installed electrolysis capacity to reach more than 550 GW by 2030.

In addition, advantageous government regulations that provide subsidies and other advantages boost the electrolyzer business. However, the market expansion is hampered by the limited supply of electrolyzers. Furthermore, the expansion of the electrolyzer market is restricted by the tardiness of authorization grants from national or local government bodies. Government policies that encourage the use of electric vehicles are underway, and in the near future, technological advancements may present a profitable opportunity for business expansion.

The market for electrolyzers is anticipated to expand if the government takes a few steps to encourage healthy energy generation. These include exempting electrolyzers from grid fees, taxes, and levies, granting access to limited electricity and grid service revenues, and acknowledging the value and cost of green hydrogen. Traditionally, electrolyzer for specialized hydrogen production have been constructed in small quantities for specialized markets. However, through economies of scale and automation, it is anticipated that increased production volumes and the corresponding expansion of factory size will lower investment costs for all electrolyzer technologies. Cost savings from the optimization of the supply chains for electrolyzer are also anticipated.

Because electrolyzer efficiency depends on system design and optimization objectives, tracking its evolution is very difficult. Comparable in efficiency, alkaline and PEM electrolyzer can function flexibly to enable direct linkage with changeable renewable electricity sources, contingent on their design. Since SOEC systems require temperatures higher than 650 °C to operate, they have reached higher electrical efficiency (84% achieved by Sunfire; however, given the additional heat input needed in SOEC systems, this is not directly comparable with other technologies). Where waste-heat is available, such as in industrial hubs, SOEC systems can be a promising solution. Recently, there have been reports of extremely high electrolyzer efficiencies from new designs. One such design is Hysata's capillary technology, which has an efficiency of 80% on a low heating value basis

Market Dynamics

Increase in concern toward reducing carbon emissions.

Global warming and carbon emissions are becoming more and more of a concern. Governments everywhere have put in place a number of policies and directives that demand a decrease in carbon emissions from a range of industries. Hydrogen is produced by electrolysis, a process that uses electricity to divide water into hydrogen and oxygen. Electrolyzers are employed in this process. One of two types of resources is used to create electricity: renewable or nonrenewable. Hydrogen can also be produced using an electrolyzer in conjunction with solar or wind power to generate energy. This process promotes the production of green hydrogen that emits no carbon. In order to reduce their carbon footprint, numerous enterprises are choosing on-site electrolyzers with a capacity of 1 to 5 MW, which significantly aids in the expansion of the global market.

Decline in costs of renewable energy.

Because of the worrisome growth in carbon emissions, the increase in global temperature, and growing concerns about climate change, renewable energy sources have become increasingly popular. In an effort to practice responsible business practices, many companies are switching from using fossil fuels to generate power to more abundant natural resources including solar, wind, natural gas, and water bodies. However, the creation of such enterprises came at a hefty initial cost. On the other hand, numerous government regulations were created in support of renewable energy due to technological developments and strong advocacy for its benefits. With the added benefit of a smaller carbon impact, the cost of renewable energy has decreased. Electrolyzer demand is driven by these declining costs. This is explained by the fact that electricity for the development of green hydrogen will come from renewable resources.

Limited technological advances

Alkaline electrolyzers have been used for the electrolysis process for many years. Alkaline electrolyzers are unstable because they can be damaged by an abrupt spike in power. The industry's technological progress was impeded by the abundance of alternatives for hydrogen generation, which hindered the electrolyzer market's expansion. Furthermore, one of the main factors impeding the worldwide electrolyzer market is the delayed delivery of equipment.

High initial costs coupled with privacy concerns and data security threat.

Upgrading to advanced electrolyzers solutions, particularly smart meters, be expensive for both utilities and consumers. These upfront costs be a barrier to adoption. The collection of detailed data by smart meters has raised privacy concerns, as it provides insights into individuals' daily routines and activities. Ensuring the security of data transmitted from smart meters is a significant challenge, as it requires robust cybersecurity measures to protect against data breaches and cyberattacks.
