WTZ

What WTZ does

WTZ Roßlau gGmbH is a non-profit applied research institute headquartered in Dessau-Roßlau, Germany, founded in 1950 by former Junkers engineers and operating under German gGmbH (non-profit limited liability) law. The institute is wholly owned by the non-profit association Trägerverein WTZ Roßlau e.V. and runs a wholly-owned commercial subsidiary, WTZ Motorentechnik GmbH. Its core technical focus is the development of CO2-neutral energy carriers — primarily hydrogen, methanol, and ammonia — for use in combustion engines and fuel cells, alongside alkaline electrolysis and the proprietary Argon Power Cycle (APC), a zero-emission closed-loop motor concept that won the Hugo Junkers Prize in 2019.

The institute operates a fully integrated R&D service offering spanning engine development, modular single-cylinder research engines (FM16–FM35, 2–50 liter displacement), engine test benches (250–7,350 kW), injection system development for renewable fuels, accredited materials testing (DIN EN ISO/IEC 17025:2018), 0D/1D and 3D-CFD simulation (ANSYS), structural mechanics FEM analysis, and prototype construction. It maintains substantial fuel infrastructure (370 kg hydrogen, 7,900 kg methanol, 6,000 kg ammonia storage) and an ISO 9001:2015-certified quality system. Marquee industrial partners include Rolls-Royce, Woodward L'Orange, MAN Energy Solutions, Alstom, MWM, and Sonplas, alongside public research funding and university collaborations.

Commercially, WTZ generates revenue through project-based B2B R&D services (industrial clients paying for engine development, testing, simulation and validation) supplemented by publicly funded research projects — over 130 such projects have been completed. FY2023 revenue stood at €11.4 million with 87 employees. The institute goes to market through direct enterprise engagement and conferences such as the Dessauer Gasmotoren-Konferenz and CIMAC. Its served segments are engine manufacturers, automotive OEMs, the rail vehicle industry, powertrain suppliers, public institutions, and universities.
