Global Hydrogen Energy Storage Market Size during 2021-2030 ($Billion)
Hydrogen energy storage systems have great market potential, and many companies are ready to grab their share of profits. But like any other solution, hydrogen energy storage also comes with many challenges alongside the benefits. Let’s discuss them in brief.
Advantages of Using Hydrogen Energy Storage
Enabling greater incorporation of renewable energy generation — While collecting the renewable power inputs from RES, hydrogen, as a kind of energy storage, can offer fuel for creating electricity or heat or fueling an automobile.
When needed, the stored hydrogen can be used to generate electricity or in other energy-intensive sectors such as the gas grid, transportation as a fuel, and industrial activities.
Hydrogen storage is not limited by region and can transfer limited renewable generation into other energy-intensive sectors.
Challenges of Hydrogen Energy Storage
High capital cost of the liquid — Currently, hydrogen energy storage is more costly than fossil fuel. The majority of these hydrogen storage technologies are in the early development stages. The quantity of energy that fuel cells can create from hydrogen and then use to meet the needs of commercial and residential buildings is exceedingly low. Due to the high insulation expenses required to prevent vaporization, the market for storing hydrogen energy in liquid form has significant capital expenditures. Hence, the time and cost of charging and discharging hydrogen in these systems and the process expenses are significant.
Strict government regulations — Stringent government rules governing hydrogen production by electrolysis have been hindering the expansion of the worldwide hydrogen energy storage sector. Several areas prohibit the manufacture and application of hydrogen. The manufacturing process can endanger the lives of those who work in factories.
