Alkaline vs PEM electrolysers: lessons learnt from Falkenhagen and WindGas Hamburg

摘要

Over the past years, Hydrogemcs has delivered several MW-scale electrolysers for Power-to-Gas demonstration projects. If m the past, these projects were dominated only by alkaline electrolysers, the most recent projects use Proton Exchange Membrane (PEM) technologies. PEM technology holds the promise of a higher efficiency, a reduction of capital cost, a higher pressure output, a lower footprint, a faster response and a more dynamic operation.
