GTT Strategic Ventures, the investment fund of GTT Group dedicated to supporting sustainable technology champions, has announced its participation in a €4 million financing round to support the development of CryoCollect, a French engineering company specialising in gas handling technologies. This investment was made in collaboration with Engie New Ventures, Engie’s investment fund for innovative start-ups that help accelerate the energy transition. The new investors join the founder and historic shareholders of CryoCollect.
CryoCollect, founded in 2017, has built a reputation for its expertise in the design and engineering of gas treatment, liquefaction, and separation technologies for gases such as bio-methane, carbon dioxide, and hydrogen. The company has assembled a multidisciplinary team of engineers and researchers, combining high-level scientific expertise with robust industrial know-how.

A notable innovation by CryoCollect is its pioneering work in capturing, purifying, and liquefying carbon dioxide from anaerobic digestion exhaust gases. This process enables the production of liquid biogenic CO2, which is part of the natural short carbon cycle and can replace fossil CO2 in industrial processes requiring CO2 as a feedstock, such as in the food and beverage industry or the production of synthetic fuels. With more than a dozen references already marketed, CryoCollect’s CO2 capture technology for biogas is the most widely deployed in its field.
Beyond biogas, CryoCollect applies its expertise in gas processing and liquefaction to other areas to accelerate the energy transition. This includes industrial CO2 capture on-board vessels, re-liquefaction of CH4 boil-off, BioLNG liquefaction for bio-methane transport, and its use as a sustainable fuel.
Philippe Berterottière, chairman and CEO of GTT, remarked, “Investing in CryoCollect aligns with GTT’s commitment to innovation and pioneering smart technologies that contribute to building a sustainable world. We are thrilled with this investment, which is poised to accelerate CryoCollect’s developments in sustainable gas production, thereby expanding the availability of bioLNG and bioCO2. This advancement will play a pivotal role in producing low-carbon fuels for the maritime industry. CryoCollect marks the sixth minority investment for GTT Strategic Ventures, our investment fund dedicated to future climate tech champions.”
Haytham Sayah, CEO and co-founder of CryoCollect, commented, “At CryoCollect, we are passionate about innovation. Since our inception in 2017, we have been committed to developing cutting-edge technologies in the field of energy, focusing on purification, liquefaction, and the valorisation of natural resources to reduce environmental impacts. Engie and GTT are natural partners for us, and we are delighted to welcome them on board. GTT has decades of experience in building a robust and efficient engineering and technology company, while Engie embraces a large array of activities (in biogas production, energy efficiency in the industry, bioLNG, etc.) that have a great fit with our portfolio of technologies. Both investors are strongly committed to accelerating the energy transition.”
This strategic investment underscores the commitment of GTT Strategic Ventures and Engie New Ventures to foster innovation and support technologies that advance the global energy transition, positioning CryoCollect as a key player in the sustainable gas technology sector.
