HaasEngineering is a chemical engineering company, founded more than 30 years ago. Our major business is to serve the chemical, pharmaceutical, and renewable energy industries. 20 years ago we worked on the first hydrogen project, which was combined with a photovoltaic plant. This was the start for us to build up a business in the renewable energy market. Whether power-to-gas, hydrogen fuel stations, or green hydrogen production for industrial plants, we offer the whole scope of engineering services starting with the needs assessment to the feasibility study, the preliminary study, basic engineering, detailed engineering, as well as supervising and commissioning all phases of a project.
