HSL Technologies has conceived the first carrier to transport and store hydrogen & silica at ambient temperature and pressure in liquid state with a non-organic basis.
These innovations consist of two innovative chemical processes that charge and release hydrogen in the carrier, combining it with silica.
This solution is called Hydrosil and offers great perspectives for green hydrogen hubs, heavy industries’ decarbonization by releasing low-carbon silica.
HydroSil is a breakthrough liquid carrier that enables energy-free hydrogen release while producing high-performance, low-carbon silica. Designed for compatibility with existing infrastructure, it offers safe, scalable, and eco-friendly solutions for both hydrogen storage and silica valorization. With up to 50% CO₂ reduction, optimized material density, and non-toxic, non-pyrophoric properties, HydroSil supports sustainable industry transformation—delivering 187 tons of silica per ton of hydrogen released.
