The annual SNEC (International Solar Photovoltaic and Smart Energy) exhibition was held for the 18th time in Shanghai, starting from June 11th last week. The focus of the exhibition has traditionally been on photovoltaic technology, but in this article we’ll be discussing electrolyzers. Up until now, China’s electrolyzer manufacturing has focused more on alkaline (ALK), while Western OEMs focused more on proton exchange membrane (PEM). As could be expected, this wouldn’t last – China is now expanding its efforts into the more technologically advanced PEM option. PEM is also the more expensive technology in terms of cost of equipment, and Chinese green energy equipment is synonymous with relentlessly reduced costs. As such, green hydrogen is about to see its cost…
