What ReiCat does

ReiCat GmbH is a privately held, 100% family-owned German engineering company founded in 1981 and headquartered in Gelnhausen, Germany, that develops, manufactures, and installs industrial-scale systems for the purification, drying, and recycling of technical gases and catalytic exhaust air treatment. Its product portfolio is organized into three lines: (1) gas purification and drying systems for hydrogen, oxygen, CO2, nitrogen, helium, argon, methane, and noble gases such as krypton, xenon, and neon; (2) gas recycling systems for helium, hydrogen, argon, and nitrogen; and (3) catalytic exhaust air purification systems, with a dedicated sub-brand family (ReiCatino®, ReiCat Gourmet, ReiCat E, ReiCat Industrial, ReiCat Module) for coffee roasters. Three proprietary technology pillars underpin the offering: catalyst technology enabling low-temperature energy-efficient purification, HighFlex H2® for stable >99.999% hydrogen purity at fluctuating flows typical of Power-to-X, and Closed-Loop technology for loss-free technical gas recovery. The company holds 6 patents and reports 580+ systems installed across 58 countries, with 1.5+ million Nm3/h of cleaned gas capacity and 300+ customers served.

ReiCat operates an enterprise B2B direct sales motion, selling custom-engineered, project-based systems on multi-year contracts to energy and Power-to-X operators, industrial gas manufacturers, chemical companies, metal/automotive manufacturers, and food and beverage producers. Revenue is generated primarily through hardware sales of purification and recycling systems, supplemented by catalyst product sales, catalyst recycling services, and custom engineering for large PtX projects. Pricing is quote-based and not publicly disclosed, with system lifespans of 30+ years creating a long aftermarket tail. Notable enterprise engagements include a 320 MW hydrogen purification system for EWE's Emden green hydrogen plant (Clean Hydrogen Coastline), two H2 purification systems for European Energy's e-Methanol flagship at Kassø, Denmark (supplying Maersk and Lego), and large-scale hydrogen recycling systems for Symrise in the flavor and fragrance industry. The company is ISO 9001 certified (since June 2023) and received the Exportpreis Hessen 2025 in the Industry category.

Partnerships

Three partnerships are on record, tiered flagship and core.

• EWEflagshipStrategic or Co-development Partner · 20 January 2026EWE commissioned ReiCat to build hydrogen purification systems for a 320-megawatt electrolyzer at EWE's green hydrogen production plant in Emden, Germany. The purification systems will achieve hydrogen purity exceeding 99.999%, enabling use in industrial applications and transportation. The Emden plant is the centerpiece of the 'Clean Hydrogen Coastline' project and will be among the largest hydrogen production facilities in Europe. Industrial-scale production scheduled to begin by end of 2027.
• European EnergycoreStrategic or Co-development PartnerReiCat delivered two H2 purification systems to European Energy - one at Kassø, Denmark where the world's largest e-Methanol plant was constructed. End customers include Maersk and Lego. System specifications include 10,506 Nm3/h flow rate at 52 MW capacity.

Broad incumbents

• Linde Engineering: Engineering division of Linde plc, a global industrial gas major, designing and building gas processing and purification plants including H2, O2, and CO2 systems. Directly overlaps ReiCat's gas purification and PtX/hydrogen scope, but at a vastly larger scale with full EPC capability.
• Honeywell UOP: Honeywell's process technology arm offering gas processing, hydrogen purification, and adsorption/catalyst solutions for refineries, petrochemical, and H2 projects. Competes with ReiCat in industrial gas purification and increasingly in PtX-related systems, supported by far larger R&D resources.
• Air Products: Global industrial gas major and hydrogen project developer. Air Products' hydrogen liquefaction and purification technology overlaps ReiCat's PtX/hydrogen business, and its scale and EPC capabilities make it a direct competitive threat on large green H2 projects.
• Johnson Matthey: UK-based specialty chemicals and catalyst company with significant hydrogen and gas processing technology offerings. Overlaps ReiCat in catalyst-based gas purification and hydrogen production, though Johnson Matthey operates at significantly larger scale across multiple process industries.
• BASF: Global chemical major with catalyst and process technology offerings for hydrogen, ammonia, and gas purification. Competes with ReiCat in catalyst-based gas purification, though BASF serves far broader end markets and brings much larger R&D and capital resources.
• Nippon Sanso Holdings: Japanese industrial gas major with global gas purification, separation, and hydrogen technology offerings. Competes with ReiCat in industrial gas purification and is increasingly active in hydrogen/electrolyzer-related projects in Europe and Asia.

Direct peers

• Topsoe: Danish catalyst and process technology company specializing in hydrogen, ammonia, and refinery process technologies. Topsoe's hydrogen purification catalysts and process know-how make it one of the closest direct comparables to ReiCat's catalyst-based purification business.
• Clariant Catalysts: Specialty chemicals company with a major catalysts business (formerly Süd-Chemie) supplying catalysts for hydrogen, ammonia, methanol, and gas processing. Directly competes with ReiCat in catalyst-based purification and reforming for industrial gas and PtX applications.
• Entegris: US-based specialty materials and gas purification company serving semiconductor and industrial gas customers with ultra-high-purity gas delivery and purification systems. Directly comparable to ReiCat in high-purity gas purification, particularly for noble gases and electronics applications.
• Pall Corporation: Filtration, separation, and purification specialist serving industrial gas, hydrogen, and chemical markets. Pall's gas purification and filtration technologies overlap ReiCat's gas treatment offerings, especially in high-purity industrial gas and chemical processing applications.
