Next development: H2EASY

Our subsidiary, HydroFlexx® is developing what we believe is the world’s safest way to store and transport hydrogen. It uses a powder based hydrogen carrier with zero CO2 emissions. The energy density of HydroFlexx® is similar to fossil fuels and twice as dense as methanol. This solution is safe to store, easy to transport and easy to scale.

How it works

H2EASY is a circular hydrogen carrier, which can carry hydrogen efficiently and safely. By adding water to the powder, the hydrogen can be released on the spot.

• 50% will be released from the added water

• 50% will be released from the H2EASY

The released hydrogen, which is of high quality, can be used directly for your engine or fuel cell. After the chemical reaction has taken place, the residue will be H2SPENT. This can be collected and regenerated for re-use. The result is a fully circular hydrogen carrier, which is also the safest.
