Role of government support in green hydrogen storage remains crucial. Different storage and transportation methods is analyzed and compared. Cost of hydrogen is expected to decrease for economies of scale. The transition from fossil fuels to renewable energy sources is seen as an essential step toward a more sustainable future.
Evaluating the economics of large-scale green hydrogen storage ensures the technology provides environmental benefits and the sustainability of the entire supply chain, from production to storage and transportation.
Given the intermittent and unpredictable nature of a renewable energy supply, green hydrogen can effectively balance energy supply and demand by converting surplus renewable energy into hydrogen for storage and transportation, thereby improving the overall stability and efficiency of the energy system .
Green hydrogen is a good medium for energy storage. Since renewable energy sources such as solar and wind power are greatly affected by the weather when generating electricity, to a certain extent, it results in waste such as abandoned wind and light.
Green hydrogen is also viewed as a promising future energy option for the aerospace sector. The application of fuel cell technology in aircraft and spacecraft is anticipated to reduce emissions and enhance efficiency, steering the aerospace industry towards a cleaner and more sustainable future . 10.2.3. Industrial Application
Market development: The strategy outlines measures to create a market for green hydrogen, including setting standards for renewable and low-carbon hydrogen, establishing guarantees of origin, and incorporating green hydrogen into the EU Emissions Trading System (ETS).
Green hydrogen: A pathway to a sustainable energy future
Energy storage: green hydrogen can be used to store excess renewable energy, such as solar or wind power. When renewable energy generation exceeds demand, green hydrogen can be produced through electrolysis, stored, and then used later to generate electricity through fuel cells or combustion turbines [ 56, 57 ].
