What Ceimig Ltd does

Ceimig Ltd is a UK-based specialty chemicals manufacturer operating from an 8,500 sq ft facility in Dundee, Scotland. Founded in 2005 as a division of Ames Goldsmith Corporation, the company manufactures, formulates and synthesises catalysts and compounds from Platinum Group Metals (PGMs), serving the green hydrogen, fuel cell, gas sensing, medical, and printed electronics markets.

Core products span five lines: optimised PEM electrolyser and PEM fuel cell catalysts (sold under the "Hyper" sub-brand) including custom catalyst ink formulations; catalytic compounds for gas and bio-sensors; specialist osmium compounds; clean room services including ECA construction and fill for the Focused Ion Beam (FIB) sector; and custom synthesis of customer-specific precious metal compounds, including non-particulate precious metal inks. The offering combines proprietary formulation know-how with clean room processing for sensitive applications, supported by ISO 9001, ISO 14001 and ISO 45001 certifications.

Ceimig operates a B2B enterprise sales model using quote-based product and technical enquiry forms, supported by a consultative field sales motion via industry trade shows (Hannover Messe, Hyvolution Paris) and trade association memberships (SHFCA, UK Hydrogen Association). Revenue derives from direct sales of standard and custom catalyst products, custom synthesis services, and catalyst ink supply. The company is the lead coordinator of the EU-funded SUPREME consortium focused on PFAS-free PEM electrolysis and reduced-iridium loading, signalling strategic positioning at the frontier of next-generation electrolyser chemistry.

Core offering

Ceimig manufactures and supplies precious metal (Platinum Group Metal) catalysts, compounds and powders, with a primary focus on catalytic materials for PEM electrolysers, PEM fuel cells, and gas/bio-sensors. The company also provides custom synthesis services, non-particulate precious metal inks for medical and printed electronics applications, and operates clean room facilities for ECA construction and fill for the FIB sector. All production takes place at the company's 8,500 sq ft facility in Dundee, Scotland.

Product overview

Ceimig Ltd is a division of the Ames Goldsmith Corporation focusing on the green energy and safety markets. The company manufactures high quality precious metal catalysts, compounds, and powders from PGM (Platinum Group Metal) materials. The product portfolio consists of five core offerings: PEM Electrolyser & Fuel Cell Catalysts (with optimised catalyst ink formulations for hydrogen production), Sensor Materials (catalytic compounds for gas and bio-sensors), Osmium Compounds, Clean Room Facilities (ECA construction for FIB sector), and Custom Synthesis Services (customer-specific catalyst development). From their 8,500ft facility in Dundee, Scotland, Ceimig also produces non-particulate precious metal inks for medical and printed electronics applications, serving industrial and research customers with both standard and bespoke formulations.

Emerging players

• American Elements: US-based supplier of high-purity precious metal compounds, catalysts, and inks for research and industrial buyers. Comparable to Ceimig in custom PGM synthesis and small-batch precious metal chemistry for sensors and electronics applications.
• Clariant: Specialty chemical producer with a catalysts business focused on industrial process and increasingly hydrogen-related applications. Comparable as a catalyst manufacturer serving adjacent end markets, though Ceimig is more deeply specialized in PGM PEM chemistries.

Direct peers

• Umicore: Belgian materials technology group active in PGM catalysis, fuel cell catalysts, and electrochemical applications. Competes with Ceimig in PEM and adjacent catalyst markets while also operating recycling loops that could anchor supply of recovered PGMs.
• Materion Corporation: US-based advanced materials supplier of precious metal alloys, catalysts, and conductive inks for electronics, sensors, and energy applications. Compares to Ceimig in non-particulate precious metal inks and PGM catalyst offerings.
• Tanaka Precious Metals: Japanese PGM specialist producing catalysts, fuel cell components, sensor materials, and precious metal inks. Overlaps Ceimig's PEM fuel cell, sensor, and printed electronics product lines with deeper automotive OEM penetration.
• Heraeus Precious Metals: Major PGM refiner and fabricator supplying catalysts, conductive inks, and specialty precious metal compounds to hydrogen, sensor, and electronics markets. Directly comparable to Ceimig across PEM catalysts, sensor materials, and printed electronics inks.
• Johnson Matthey: Global specialty chemicals and PGM catalyst manufacturer with hydrogen applications as a core growth pillar. Closest direct competitor to Ceimig in PEM electrolyser and fuel cell catalysts, with substantially larger scale and global OEM relationships.

Others

• FuelCell Energy: Fuel cell stack and system developer that consumes PGM catalysts at scale and is part of Ceimig's potential customer ecosystem. Useful ecosystem reference for sizing the downstream demand that Ceimig's PEM fuel cell catalyst products address.

Broad incumbents

• Evonik Industries: German specialty chemicals company producing catalysts and high-performance materials, including fuel cell and electrolyser-adjacent products. Broad incumbent with overlapping capability in catalyst formulations serving hydrogen markets.
• BASF: Global chemical incumbent producing catalysts, battery materials, and precious metal compounds for industrial customers. Overlaps Ceimig broadly through catalyst and chemistry portfolios, but is far broader and not specialized in small-batch PGM PEM ink formulations.
