What Wolftank Group does

Wolftank Group AG, headquartered in Innsbruck, Austria, and founded in 1987 (with the brand claiming over 70 years of industry experience tracing back to 1950), is a B2B technology partner operating across three business pillars: hydrogen and renewable energy infrastructure (turnkey H2 and LNG refueling stations, mobile hydrogen stations, dispensers, and logistic containers at 350 and 700 bar), industrial coatings and tank renovation (including the patented DOPA technology and No-Man-Entry Bruco/Superbruco robot-assisted cleaning systems), and environmental services (soil and groundwater remediation, waste management, decommissioning, and industrial water treatment).

The company generates revenue through project-based turnkey contracts with engineering, delivery, installation, and commissioning included. Disclosed contract sizes for hydrogen refueling stations range from EUR 4.9 million to EUR 15.5 million per project. Its core customers are public transport operators (notably TPER in Italy, with cumulative contracts worth approximately EUR 29.9 million across three sequential awards) and energy companies (Guttroff GmbH in Germany for the H2 Main-Tauber Hub), alongside industrial facility owners requiring tank rehabilitation and environmental remediation services.

Wolftank operates through wholly-owned subsidiaries in 7-8 countries across three continents, with operational hubs in Italy (Rovereta, Sirigenera, Ostellato, Petroltecnica, Wolftank Italy, Mares Italia) and Germany (Illertissen, Zwickau, Dettelbach). The company is publicly listed on the Vienna Stock Exchange direct market plus segment and Munich Stock Exchange m:access segment, with a GreenLead 2030 strategy targeting EUR 250 million in revenue and 12% EBITDA margin by 2030 across three innovation fields: battery recycling, PFAS decontamination, and automated tank remediation.
