However, scaling electrochemical compression technology for large-scale industrial applications remains a challenge.

Hydrogen Production & Distribution

temperature or high-pressure variants can reduce the electrolysis energy use. As for hydrogen storage, compression energy amounts to 10-15% of the hydrogen energy content (up to 30% for very high pressure) while liquefaction absorbs between 30% and 40% of the energy content. Hydrogen production costs depend basically on process, feedstock and

Electrochemical Hydrogen Compression: Modeling, Internal

However, for a successful hydrogen economy to develop, the compression and storage costs of hydrogen must be lowered to overcome its low volumetric energy density (i.e., 0.01079 MJ/L at STP). Currently, conventional mechanical compression accounts for the largest percentage of operating costs in hydrogen refueling stations [1].
