The KOBELCO Screw HyDryModule (HDM) is a standardized, oil-free hydrogen compressor package designed for electrolyzer applications. By integrating dry screw compressors with gas coolers, separators, piping, recycle valves, and auxiliary systems into a single skid-mounted package, HDM provides a reliable and efficient plug-and-play solution for hydrogen compression. Available for electrolyzer capacities from 50 MW to 1 GW, the HDM helps simplify installation, reduce project execution risk, and support the scale-up of green hydrogen production worldwide.
