H2RENEW™ provides on-site gas recycling to recover and purify process hydrogen. H2RENEW™

systems can also generate hydrogen to supply 100% of process gas requirements, completely

eliminating the reliability and logistics issues associated with trucks and cylinders. Hydrogen

compression to > 3,000 psi for storage and later reuse is available.

H2RENEW™ systems provide a fresh, pressurized, re-supply of hydrogen from a wasted stream of

“used” hydrogen at a fraction of the cost of makeup gas, recycling hydrogen process atmospheres

used in heat treating, specialty metals, microelectronics, glass manufacturing, and electric

generator cooling. H2RENEW™ can be configured to recover cryogenic hydrogen boil-off.
