Green Hydrogen: Production from Renewable Energy Sources, Challenges and Future Prospects

Author: Dr. Kumari Sarita Prasad

Category: Engineering, Science and Mathematics

Full Text:

A promising sustainable energy source for attaining global decarbonisation and lowering reliance on fossil fuels is green hydrogen. With almost no greenhouse gas emissions, it is created by electrolysing water using renewable energy sources like solar and wind. Green hydrogen has major environmental benefits over traditional coal and natural gas-based hydrogen production techniques. Alkaline electrolysis, proton exchange membrane (PEM) electrolysis, and solid oxide electrolysis are the three main technologies that are critically assessed in this chapter along with the basic concepts of water electrolysis. A thorough analysis is conducted of the main obstacles, which include high production costs, energy losses, storage challenges, transportation problems, and inadequate infrastructure. Additionally highlighted are recent technological developments in large-scale deployment strategies, system efficiency, and catalyst design. Lastly, prospects and policy for the future Finally, future prospects and policy frameworks supporting the global hydrogen economy are presented. Green hydrogen is expected to play a crucial role in achieving carbon neutrality and sustainable energy security in the coming decades.
