With over 70 years of experience, it carries out projects covering many areas such as energy mobility, storage, and environmental services. Wolftank Group's key business sectors include: Hydrogen and Renewable Energies, Industrial Coatings, Environmental Services, and Turnkey Refueling Stations.
With more than half a century of engineering experience, Wolftank Group is a global technology partner in the fields of energy infrastructure modernization and environmental rehabilitation. The company specializes in the hydrogen economy, the safety of industrial storage systems, and the in-situ remediation of contaminated land.
The storage and distribution of hydrogen play a critical role in the emission-free transportation infrastructure of the future. To support this transformation, Wolftank develops turnkey hydrogen (H2) refueling stations.
Filling Technologies: Modular systems are designed that offer high-security filling at both 350 bar (heavy vehicles) and 700 bar (passenger cars) pressure levels.
Cryogenic Storage: High-insulation tank solutions are provided that allow LNG and hydrogen to be stored in liquefied form with minimum energy loss and maximum sealing safety. These systems can be installed across a wide range of scales, from logistics centers to public transport networks.
Advanced "retrofitting" technologies are applied to eliminate the environmental risks of existing storage tanks and extend their service life.
Double-Wall Conversion: Old single-walled tanks can be converted into a double-walled system without the need for tank removal. Leak detection sensors placed between the two walls provide 24/7 monitoring, completely preventing soil and groundwater contamination.
Special Coating Solutions: Epoxy-based interior coatings protect tanks against corrosion and aggressive chemicals. This process saves the cost of a new tank investment while extending the infrastructure's life to over 20 years.
Ecosystem-friendly methods are preferred for the cleanup of soil and groundwater contaminated by industrial activities.
In-Situ Remediation: Unlike traditional "excavate and transport" methods, contamination is treated at the source (via bioremediation, air injection, or chemical oxidation) without the need to move the soil. This method allows for the removal of pollution without halting facility operations.
All these processes are integrated with digital monitoring software, providing operational efficiency and predictive maintenance opportunities. Infrastructure solutions are designed to be fully compliant with global emission standards.
These technologies do not only clean up pollution; they aim to complete the sustainable transformation of industrial facilities by preparing existing energy infrastructures for next-generation clean fuels.
