This is likely to fuel the growth rate of the electrolyzers market.

MARKET RESTRAINTS

A shortage of skilled labour is slowly hindering the growth rate of the electrolyzers market.

The soaring price of electricity is becoming a major threat to the growth of the electrolyzer market. As the process completely depends on utilizing electricity, the soaring prices may affect the overall productivity, which will impede the market’s growth. Along with this, huge disruptions in the supply chain activities also limit the share of the market. The disruptions in the supply chain will eventually increase the cost of the final products due to the lower availability of raw materials. The overall process needs a proper infrastructure. A proper setup is required to produce green hydrogen through the electrolysis process, where the lack of this infrastructure in many industries due to its high cost for installation and other factors is likely to limit the growth rate of the market.

MARKET OPPORTUNITIES

On-going research and development activities to implement Fuel Cell Electric Vehicles (FCEVs) powered by hydrogen shall create huge growth opportunities for the electrolyzers market. FCEVs are highly convenient and emit no harmful emissions into the environment, which is gaining attention from the government and non-government authorities to invest huge amounts. The complete process of generating hydrogen from water depends on electrolysis, where the electrolyzer plays an important role in enhancing the activities to promote FCEVs in the future.

In addition, higher authorities around the globe are focusing on transforming the production and consumption of energy in various ways. Net zero carbon emissions by 2050 is focusing on implementing different strategies to completely make the countries pollution free. Their main focus is on the energy sector where the adoption of innovative technologies like electrolyzer has a high potential in reaching the goal of net zero emissions by 2050 which is likely to surge the market growth rate in the foreseen years.

MARKET CHALLENGES

Reluctance to adopt these changes with a lack of significant knowledge over the positive impact of the electrolyzer in a few industries may be challenging factor for the market key players. Stringent rules and regulations by government bodies in adopting the new technologies are also likely to stymie the growth rate of the market.
