HoSt Group

Our history Founded by Herman Klein Teeselink in 1991 through a joint venture between Holec Projects and Stork, HoSt Group has thrived under family ownership. Since 2020, Jelle Klein Teeselink has been part of the management team, upholding the family-owned company. Our global team of over 500 dedicated professionals operates across seven countries, with offices in both the US and Europe. We are passionate about advancing renewable energy technology worldwide, accelerating the renewable energy transition, the circular economy, and helping our clients reach their sustainability goals. To date, we have built more than 450 systems in over 35 countries — some of which have been operating successfully for over two decades. Research & development Rooted in a culture of innovation and entrepreneurship, HoSt has achieved leadership in the field of renewable energy solutions through a focus on in-house technology development. This includes several patented technologies and a robust R&D pipeline set for the coming years. Our streamlined product lines stand out for their efficiency, ROI, and commitment to sustainability, featuring low emissions and continuous innovation. At our full-scale Wabico research facility in Waalwijk Netherlands, we test new renewable gas technologies before launching them and optimize existing ones. Our in-house large testing facility with laboratory at our HyGear office is one of the most advanced testing facilites in the Netherlands, while our laboratory at our head office helps with key analyses and laboratory-scaled studies. Running our own renewable gas and heat and power facilities lets us fine-tune our technologies based on real-world data before we market it worldwide.
