Green hydrogen: A pathway to a sustainable energy future
Green hydrogen is a promising technology that has been gaining momentum in recent years as a potential solution to the challenges of transitioning to a sustainable energy future [4, 5].The concept of green hydrogen refers to the process of producing hydrogen gas through electrolysis, using renewable energy sources such as solar, wind, or hydroelectric power.
Green hydrogen: the energy of the future essential for
However, hydrogen is not a primary energy source but an energy vector, that is, it requires a chemical process to produce it. You have probably heard that hydrogen is a renewable fuel, but this is not always true. Hydrogen is only renewable if the process used in its extraction is also renewable. Let''s look at what forms of hydrogen production
Hydrogen Energy
Hydrogen energy is the practice of utilizing hydrogen and/or hydrogen-containing compounds to produce energy that can be used for all practical purposes while obtaining high intensity production, major environmental and social advantages, and economic viability (Qyyum et al., 2021). From: Renewable Energy and Sustainability, 2022
