Hydrogen energy storage system has great market potential, and a lot of 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 for fueling an automobile. 

When needed, the stored hydrogen can be used to generate electricity, or it can be used 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. (Source)

Challenges of Hydrogen Energy Storage

High capital cost of the liquid – At the moment, 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 the production of hydrogen 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. (Source)(Source)

Hydrogen as an energy storage system definitely has many benefits, but first, companies and Governments need to work on its main challenges.

China has already announced its long-term hydrogen plan that includes a goal to produce 100,000 to 200,000 tons of renewable-based hydrogen annually and have a fleet of 50,000 hydrogen-fueled vehicles by 2025.

China is the highest producer of Hydrogen and positions third in Fuel Cell EVs. The market for Fuel Cell EVs will shoot up as China produces the highest renewable hydrogen.

The Indian government, along with Reliance Industries and Adani Group, also announced plans and investments in Hydrogen energy to use it for different industries.

Going forward, it will be interesting to see the growth and market trends of hydrogen storage and how it influences the energy storage sector.
