Growing demand for hydrogen is driving the market growth
Market CAGR for hydrogen electrolyzers is being driven by the rising demand for hydrogen. A viable technique for producing carbon-free hydrogen from nuclear and renewable sources is electrolysis. The process of electrolysis involves utilizing electricity to divide water into hydrogen and oxygen. This process takes place in an apparatus called electrolyzes. Electrolyze devices use electrolysis to separate oxygen and hydrogen from water. Electrolyzes are composed of an anode, a cathode, and a membrane. Hydrogen is collected on the cathode side and maintained for use in many industries.
Either oxygen is released into the atmosphere, or it is retained and used in further industrial operations.
Additionally, concerns about global warming and carbon emissions have been raised. Governments everywhere have passed a plethora of laws and policies requiring a reduction in carbon emissions from various industries. Using electricity electrolyzes separate water into hydrogen and oxygen. This produces hydrogen. Either renewable or nonrenewable resources provide the electricity that is used. Moreover, electrolyzes combined with solar or wind power can be used to create hydrogen. This strategy encourages the creation of green hydrogen that is carbon neutral.
Many businesses choose to use on-site electrolyzers with a capacity of 1 to 5 MW in order to lessen their carbon footprint, which has a major positive impact on the growth of the worldwide electrolyzer industry. Electric cars with batteries are powered by hydrogen fuel cells. By limiting carbon emissions, driving an electric automobile lowers air pollution.
The popularity of renewable energy sources has surged due to worries about climate change, the rise in earth's temperature, and the concerning growth in carbon emissions. Many companies have abandoned the conventional method of producing electricity from fossil fuels in favor of using plentiful natural resources like solar, wind, natural gas, and water in order to behave responsibly. Nevertheless, there was a substantial upfront cost associated with establishing such programs. Conversely, a lot of advantageous laws have been passed by the government as a result of technological advancements and vigorous support for the advantages of renewable energy.
The cost of renewable energy has come down while maintaining a much smaller carbon footprint.
The need for electrolyzers is fueled by these falling prices. For instance, estimates indicate that fossil fuels account for about 95% of the hydrogen produced. Electrolysis produces between 1% and 4% of hydrogen. Utilizing hydrogen as a fuel in industrial applications such as manufacturing, chemistry, and locomotives encourages the use of hydrogen obtained from renewable sources, such as electrolyzers, in light of the growing emphasis on reducing carbon footprints. This stimulates the growth of the electrolyzer market.
The demand for hydrogen fuel cells is rising as a result of the growing market for fuel-cell automobiles, which also drives the market for electrolyzers. Thus, result in driving the Hydrogen Electrolyzers market revenue.
