The prevailing levelised cost of Green Hydrogen (LCOH) is 1.75 times that of grey hydrogen and 1.50 times that of brown hydrogen, posing a significant barrier to its adoption. Achieving economic viability of Green Hydrogen to around $2.1 per kg requires a 35%-40% drop in electrolyser prices and a 12%-14% improvement in efficiency apart from supportive policies, says a new report by CareEdge Ratings.
