The hydrogen atom is the simplest chemical element, the most abundant on Earth and the oldest in the universe (it appeared 13 billion years ago). It is not very present on Earth in its natural state, but it is very widespread in the combined state in many substances, in particular with oxygen, with which it forms water, and carbon, with which it forms all the hydrocarbons. The calorific value of hydrogen is the highest of all existing fuels. It is two to three times more energetic than oil or gas and its combustion releases only water.

The use of hydrogen as an energy carrier involves several steps: hydrogen production, storage, transportation, distribution, and conversion of the stored energy into electricity.

As with any energy conversion, each step is accompanied by a loss, which impacts the efficiency of the whole chain. The overall efficiency of the production-storage-transport-restoration chain depends on the manufacturing process and the distance over which the hydrogen was transported distance over which the hydrogen was transported.

HydroSil is the only hydrogen carrier solution that can liberate H2 in a few seconds and with no external energy input. Its liquid form enables to use the existing oil & gas infrastructures (trucks, tanks etc.), which makes its logistics much simpler and considerably cheaper than that of any existing alternative. It totally fits the needs of the mobility sector by simplifying the hydrogen transport and storage. Our disruptive technology is the only one that fulfils every demand form the market and it’s also the only technology based on silicon hybride molecule, which is non toxic for humans and environment.

Our solution comprises two main processes: the charging of the hydrogen in the liquid and the release of the hydrogen from the liquid. It enables to release hydrogen at the consumption site easily, on-demand and without any external energy input. Furthermore, it can be reused as many times as desired: HydroSil is fully re-usable. After releasing the H2, it is sent back to the supplier to be charged again as many times as required (no additional treatment required). The purity of the H2 released is extremely high (>99.99999%), being therefore adequate for its direct use in fuel-cells.





After the hydrogen is produced, it is charged into HydroSil through an innovative chemical process. This operation is performed at the industrial plant right after the hydrogen production.

No carbon is used during this process.

All the infrastructure will be built locally.

Hydrogen is easily released through a chemical reaction in a small carburettor, with no external energy required. This operation only requires small installation, enabling an easy deployment. The release of the hydrogen can be done on demand at the consumption site (discharge in less than 10 seconds of 100% of the hydrogen contained in the liquid, short-term application), or on-board in case of large vehicles (long-term application). The discharged HydroSil is brought back to the synthesis site to be recharged, without limitation of the number of cycles, without additional treatment.

Delivery of H2 to all of our customers

Delivery of H2 to all of our customers

Sectors such as maritime and rail are developing hydrogen systems to comply with new regulations. About 90% of all trade between countries takes place by ship and, as this sector has to reduce its emissions by 50%.

Hydrogen is the only zero emission fuel that can provide the same use as oil-based ones. Indeed, the possibility of on-board hydrogen release is one of the biggest advantages provided by HySiLabs’ technology. It is the only solution enabling the release of hydrogen on-board of vehicles from a safe liquid, with no energy required and without emissions.

Long-term storage

Large-scale underground hydrogen storage is indispensable to the European hydrogen market and will become a key part of the decarbonized energy system. It enables efficient planning and use of infrastructure (electricity, hydrogen) and add flexibility to the system, reduces needs to overbuild production, transmission capacities vis-à-vis expected demand. The first estimates show a H2 storage capacity need of 70 TWh H2 by 2030 and 450 TWh H2 by 2050 (according to Gas Infrastructure Europe).

Green H2 transportation

The Green H2 import has already be planned in some countries. For example, Japan aims to import 2 million tons of H2 per year in 2030.The Environmental and Energy Management Agency of France (ADEME) has also worked on various scenarios to achieve carbon neutrality by 2050. In the third scenario, entitled “Green technologies”, massive consumption of green hydrogen is expected in 2050. The half of this hydrogen will have to be imported (48 TWh).



In June 2022, we inaugurated our first pre-industrial demonstrator. Having demonstrated our ability to produce our carrier in the laboratory at the gram level, we are now entering a phase that will enable us to move from the kilogram to the ton. This stage will enable us to draw the outlines of our future factory, to show that it can operate autonomously. We are going to carry out numerous tests to prepare our industrial pilot, which should be delivered in three years. This is a first step towards the industrialization of HydroSil production by 2027-2028.
In 2025, three industrial pilots will be installed to start using HydroSil in concrete use cases, with partners on the three targeted applications.

From 2027, the HydroSil solution will be fully commercialized and HySiLabs' turnover will reach an industrial level.
