Technological and Economic Challenges Faced by Green Hydrogen: An Opinion

Department of Orthopedic Surgery, Mayo Clinic College of Medicine, Minnesota, USA

With the increasing focus of the market towards the low carbon energy sources to address climate change problems while maintaining sustainable development, there is an increased demand to reduce the carbon footprint of the current processes in energy sector by either modifying the existing technology or developing the new technologies, which has led for the consideration of hydrogen as an energy carrier in transportation and various industrial applications. In this article we will discuss some of the prevalent processes that are being used industrially for the hydrogen production and what are the challenges that need to be addressed for reduction of their carbon footprint. Hydrogen classification based on the carbon footprint of its production process will be discussed in brief.
