Unlocking the Opportunities: Green Hydrogen from Renewable Energy Sources

Hydrogen is the cleanest fuel among the existing with high calorific value ranging from 120 to 140 MJ/kg. It is being considered as ‘a fuel of the future’ from the global warming perspective due to very low or zero carbon emissions. Hydrogen energy is becoming a key component in bringing about the energy transition to ensure a sustainable future. Due to its very high potentials to capture the market in several fields, including automobiles, power generation, chemical, petrochemical and steel industries, and domestic uses, a lot of research has been going on and several innovations have been made in the technologies related to hydrogen production. It can be generated using fossil fuels as well as renewable sources which include natural gas, coal, nuclear, biomass, solar, wind, hydroelectric, and geothermal energy. This book chapter explores the potential of green hydrogen energy generation using renewable energy sources, including solar, wind, and hydroelectric power. It discusses the advantages of making use of renewable energy sources for green hydrogen generation, including the elimination of carbon emissions associated with traditional methods. This chapter also explores the challenges and opportunities associated with green hydrogen energy production with the help of renewable sources of energy, including the need for infrastructure development and investment in their research and development. Overall, this book chapter provides a comprehensive overview of the advantages of green hydrogen energy generation using renewable sources of energy and highlights its role in the gradual shift to a carbon–neutral economy along with future prospects.
