NEA Hydrogen Piston Compressor

  • Hydrogen is the fuel with the highest energy content per weight. The density of hydrogen in atmospheric conditions is only at 90 grams per cubic meter.
  • In order to achieve usable levels of energy density, efficient compression of hydrogen is essential. NEUMAN & ESSER GROUP with far more than 100 years of experience in hydrogen compression offers a broad portfolio of hydrogen compressors.
  • If high quantities of oil-free hydrogen are needed, the many thousand-fold proven and tested dry running NEA API 618 piston compressors are the answer. Far more than 10 Megawatts of drive power can efficiently be used to fulfill any hydrogen compression requirement.
  • If traces of oil are allowed in the gas, discharge pressures in the range of more than 600 bar (9,000 PSI) are possible with lubricated compression. For high volume flows and high pressures, the combination NEA Piston stages with diaphragm heads on a “hybrid” compressor offers a veritable hydrogen compressor solution.
