WS Reformer GmbH

What WS Reformer GmbH does

WS Reformer GmbH is a privately held German engineering firm founded in 2003 in Renningen (Stuttgart region), operating within the WS Group conglomerate. The company designs and manufactures decentralized hydrogen production equipment, built around proprietary FLOX® combustion technology licensed from its parent WS Wärmeprozesstechnik. Its portfolio spans three product lines: (1) the FLOX® Reformer Modular M50, a medium-scale steam reformer for natural gas or biogas with modular scalability up to 400 Nm³/h of hydrogen; (2) the FLOX® Reformer Compact, a 1–10 kW micro-scale reformer for residential and commercial fuel cell CHP systems; and (3) the FLOX®-Cracker NH series (NH20 pilot, NH120 industrial, and the newer NHxx large-scale design) for ammonia-to-hydrogen conversion, with the NH120 demonstrated at over 1,000 operating hours producing ~200 Nm³/h H₂ from 100 kg/h NH₃. Patented heat exchangers and a highly integrated reactor design — combining desulfurization, steam generation, and CO-shifting in one unit — underpin the technology stack.

The firm monetizes through one-time capital equipment sales of reformer and cracker modules, supplemented by strategic and techno-economical consultancy engagements drawing on more than 20 years of fuel cell and reforming expertise. Go-to-market is enterprise direct sales targeting plant manufacturers, project developers, fueling-station operators, biogas plant operators, and emerging ammonia-based hydrogen users in shipping, heavy mobility, and remote power. Distribution leverages direct customer engagement, industry events such as H2 EXPO Hamburg, and the WS Group ecosystem — notably sister companies e-flox (plant manufacturing) and BtX energy (project planning) — which together deliver integrated plant solutions. Geographic reach spans Germany, Korea, China, the USA, South Africa, India, and Russia, with a November 2025 MOU with Norway's Hydrogen Mem-Tech AS targeting broader European distributed-hydrogen deployment.

Core offering

WS Reformer GmbH designs, develops and manufactures small-to-medium scale hydrogen production systems based on its proprietary FLOX combustion technology. Its portfolio includes modular steam reformers for natural gas and biogas, micro-scale reformers for fuel cell combined heat and power (CHP) systems, and ammonia crackers (NH20, NH120, NHxx) for decentralized ammonia-to-hydrogen conversion. The company also offers strategic and techno-economical consultancy services for hydrogen projects.

Product overview

WS Reformer GmbH offers a portfolio of hydrogen conversion technologies based on proprietary FLOX® combustion technology. The product portfolio spans three core technology lines: (1) FLOX® Reformer Modular M50 for decentralized steam reforming of natural gas and biogas at medium scale (up to 400 Nm³/h); (2) FLOX® Reformer Compact series for micro-scale steam reforming powering residential fuel cell CHP systems (1-10kW); and (3) FLOX®-Cracker NH series (NH20 pilot, NH120 industrial, NHxx large-scale) for ammonia-to-hydrogen conversion at various capacities. All products share the proprietary FLOX® combustion technology, patented heat exchangers, and indirect radiative heat transfer. The offering is complemented by strategic and techno-economical consultancy services.
