2.7 to 6.4 kWh of electricity is required to compress hydrogen at 700 bars in large-scale, new facilities

A review of one source indicates that the energy requirements for compressing hydrogen to 700 bar typically range between 2.68 to 6.46 kWh per kilogram.1 This range is influenced by various factors, including the type and efficiency of the compressor and the hydrogen's initial pressure before compression. Many modern compressors can achieve efficiencies to the lower end of this range.2
