A technoeconomic analysis of hydrogen production in a high renewable resources electricity grid using alkaline electrolysis, polymer electrolyte membrane electrolysis and solid oxide electrolysis.

Hydrogen can be a clean energy carrier, the utilization of which can help to reduce emissions and can potentially help in decarbonization of various sectors. The current study presents a technoeconomic analysis of hydrogen production using three electrolyzer technologies-alkaline electrolysis, polymer electrolyte membrane electrolysis and solid oxide electrolysis. The study considers the electricity system of Karnataka, a leader in renewable energy in India.
