Hydrosil's Slogans & Taglines

HydroSil is a unique liquid carrier facilitating the transport and storage of hydrogen. Developed by HSL Technologies (formerly HySiLabs) and founded in 2015 in Aix-en-Provence, France, the technology addresses one of the most critical challenges in the hydrogen economy: safe, efficient long-distance transportation and large-scale storage. HydroSil is a liquid silicon hydride derivative that remains stable at ambient temperature and pressure, enabling hydrogen to be transported using existing liquid fuel infrastructure. The carrier achieves a hydrogen density of 8.7% by weight and can store seven times more hydrogen per truck than compressed gas at 200 bars. A distinguishing feature is that hydrogen can be released on demand through a simple chemical reaction with water and a catalyst, requiring no external energy input. In 2022, HSL Technologies inaugurated the HyPlant pre-industrial demonstrator, and in 2023 secured €13 million in Series A funding led by Equinor Ventures. The company plans to install industrial pilots by 2025 and achieve full commercialisation by 2027.
