Absolut Hydrogen

Absolut Hydrogen is a French industrial engineering SME based in Grenoble.

A subsidiary of the Groupe Absolut, Absolut Hydrogen aims to make liquid hydrogen accessible to decarbonise the industrial and mobility sectors.

Thanks to the know-how of the Groupe Absolut, it is today the only independent entity positioned on the LH2 market with multi-sector application expertise in cryogenics. Absolut Hydrogen offers a range of energy-related technological solutions: liquefiers, reliquefiers, storage and zero boil-off.

Maritime uses of zero-emission liquid hydrogen:

Absolut Hydrogen is developing technologies adapted to the maritime environment:

-On-site liquefaction of LH2;

-Storage on board with zero boil-off and transfer of LH2;

Filling of LH2 ship tanks.

LH2 enables:

- 3 times the distance travelled, with the same size and weight (including systems), using LH2 for a ship means a gain in range of a factor of 2 to 3 compared with GH2 (gaseous hydrogen)

-Save space on board, as the volume taken up by the fuel is reduced, giving more payload space.

- Reduce CAPEX & OPEX by not having to resort to compression (regular maintenance & high cost), which is necessary for GH2.

Absolut Hydrogen offers on-site liquefaction adapted to your daily requirements.

Absolut Hydrogen is also developing a complete range of "reduced boil-off" mobile storage systems. These storages will be integrated into complete ecosystems, enabling full control of the LH2 system.

Absolut Hydrogen offers ZBO solutions for long-distance shipping, thanks to the marinization of its small-capacity liquefiers, which provide a solution for the large masses on board ships.
