Wulf Johannsen
Sustainable Business Practices & Sustainable Resource Management
At Wulf Johannsen, we work every day to achieve the highest efficiency and powerful, long-lasting engines and to ensure that combined heat and power (CHP) systems, global freight transport, and domestic industry are all heading toward a sustainable future. To this end, Wulf Johannsen relies on sustainable electricity generation and energy-efficient heating of its own buildings and facilities.
Engines For The Future
Repair Instead Of Buying New
Restoring used and worn components is both environmentally and economically sustainable. The key concept here is remanufacturing.
By applying new coatings to worn surfaces, components such as engine blocks, cylinder heads, shafts, and axles can be restored without any loss in performance or durability.
Refurbished at a low cost, these components can continue to operate reliably for many more years.
This approach helps avoid significant CO₂ emissions typically generated through energy-intensive processes like melting and casting metal, machining, hardening, and the transportation of new components.
Good for the environment and your wallet
Remanufacturing
Remanufacturing refers to the process of restoring a used device to the standard of a brand-new product.
This approach is not only environmentally sustainable, but also significantly reduces the high costs of new acquisitions and the long lead times associated with sourcing new parts.
At Wulf Johannsen, we employ differend techniques such as wire flame spraying, cold gas metal spraying, shrink-fitting or expansion-fitting of bushings and rings, and the manufacturing of new bearings to prepare components for future use.
We are your reliable partner for the cost-efficient restoration of engines and components — ensuring performance, durability, and sustainability.
Local energy generation
Our Photovoltaic System
Since 2023, Wulf Johannsen has been generating its own electricity.
A total of 616 solar modules installed across more than 1,360 square meters of rooftop area produce approximately 247,000 kWh annually. This allows Wulf Johannsen to cover around 40% of its electricity needs independently. The energy generated is primarily used to power the company’s own manufacturing and processing machinery, as well as to operate its in-house heat pump.
Sustainability Dialed In
100% Green Electricity – And It's Certified!
Electricity that Wulf Johannsen cannot generate through its own photovoltaic system must be sourced externally. We place great importance on ensuring that our entire operation runs on 100% green electricity from renewable energy sources.
Remaining committed to our region, we exclusively use 100% certified green electricity from wind power plants located in Schleswig-Holstein, provided by our partner Stadtwerke Kiel AG. This same provider also supplies green energy to our new electric charging stations. In doing so, we actively support climate-neutral mobility for both our employees and customers.

Heating With A Heat Pump
Heating marks an important link in our commitment to sustainability. At Wulf Johannsen, we rely on state-of-the-art heat pump technology to supply our buildings with warmth. Our modern office building is ideally suited for this system, allowing us to efficiently heat over 500 square meters of office space via underfloor heating.
The heat pump is powered by electricity generated from our own photovoltaic (PV) system. Should the self-produced energy ever fall short, the system seamlessly switches to 100% certified green electricity—just like the rest of our facilities and buildings.
