Wolftank Austria

What Wolftank Austria does

Wolftank Group AG (Wolftank Austria), headquartered in Innsbruck, Austria, and publicly listed on the Vienna Stock Exchange under ticker WOLT, is a 70+ year-old industrial technology company operating across four business areas: hydrogen and renewable energy refueling infrastructure, industrial tank coatings, environmental services (soil and groundwater remediation, decommissioning, waste management), and turnkey hydrogen and LNG refueling stations. The company's core technology stack combines proprietary hardware — turnkey mobile and stationary hydrogen refueling stations, advanced tank coating and double-wall upgrade systems, and in situ soil/groundwater remediation equipment — with a software platform that currently monitors and manages 180+ hydrogen sites and has supported 31,000+ refueling operations. Operating in more than 20 countries with 51-100 employees and 25+ intellectual property rights, Wolftank has executed 51,500+ commercial tank renovations and approximately 6,500 environmental remediation projects, establishing a deep industrial track record.

Wolftank's commercial model is built around large, project-based infrastructure contracts with enterprise and government clients, particularly municipal and regional public transport operators, as illustrated by its EUR 25 million cumulative partnership with Italian operator TPER including the EUR 4.9 million Battindarno hydrogen refueling station in Bologna fueling Italy's largest 127-bus hydrogen fleet. Revenue streams combine one-time project licenses for hydrogen infrastructure, professional services for remediation and coatings, and a smaller subscription/recurring software layer for ongoing site management. The company pursues a direct enterprise field-sales motion, supplemented by industry events (UNITI Expo 2026, Ecomed Green Expo) and active investor-relations communications consistent with its public listing. Quality and regulatory compliance are central to its positioning, with ISO 9001, ISO 14001, ISO 45001, and BS OHSAS 18001 certifications supporting eligibility for EU/Italian PNRR-funded infrastructure projects. Recent strategic moves include a May 2026 U.S. partnership with High Impact Technology, LLC for entry into critical infrastructure and defense markets, and Q1 2026 results showing 46% sales growth and near-quadrupled EBIT following a stabilization phase in 2025.

• McPhy Energy: French provider of hydrogen production, storage, and refueling equipment, directly overlapping with Wolftank's hydrogen station and renewable energy portfolio. Targets similar European mobility and industrial customers with turnkey electrolyzer-to-nozzle solutions.
• Nel ASA: Norwegian manufacturer of hydrogen refueling stations and electrolyzers, closely matching Wolftank's H2 station offering. Both compete for European fleet-operator hydrogen depot contracts and sell turnkey refueling infrastructure to public transport and industrial customers.

Others

• Worley: Global engineering, procurement, and construction firm with a dedicated hydrogen and energy transition practice. Comparable to Wolftank as an EPC and integration partner for hydrogen and environmental infrastructure projects.
• Babcock & Wilcox: Provider of environmental and industrial services including remediation and emissions control. Overlaps with Wolftank's environmental services and industrial coatings businesses serving energy and industrial customers.

Broad incumbents

• Air Products and Chemicals: Global hydrogen and industrial gas giant with major hydrogen mobility and refueling infrastructure projects. Overlaps with Wolftank at the fleet-depot hydrogen station level but operates at vastly greater scale across the full H2 value chain.
• Cummins (Accelera): Accelera is Cummins' zero-emission powertrain and hydrogen solutions business. Targets similar heavy-duty mobility and refueling customers as Wolftank, particularly for hydrogen-powered bus and truck fleets.
• Linde plc: Global industrial gases major with a large hydrogen and clean energy business. Competes broadly with Wolftank across hydrogen supply, mobility refueling, and industrial decarbonization, though as part of a much wider portfolio.
