H2 ENERGY

Physics

Hydrogen has physic properties allowing it to be a promising energy vector and zero-emission powered transport solution.

H2 can be used as a fuel – instead of fossil-fuel – providing useful and zero emission energy. Gaseous hydrogen is usually compressed from 350 bar to 700 bar due to its lightweight and low density.

Molecular hydrogen is also called di-hydrogen. This diatomic molecule is composed of 2 hydrogen atoms held together, giving its chemical formula called H2.

Hydrogen is the most abundant chemical element, estimated to contribute 75% of the mass of the universe, being present in nearly all molecules in living things. It can be used as a zero-emission power source (zero-emission during use and zero-emission for the complete logisitic chain from well to wheel could be envisaged when using renewable electricity), releasing only water vapor and heat in the atmosphere during the use through a fuel cell.

Molecular hydrogen is also called di-hydrogen. This diatomic molecule is composed of 2 hydrogen atoms held together, giving its chemical formula called H2.

Hydrogen boiling point is at – 250 °C at atmospheric pressure. Absolut System technologies will help to manage this extreme temperature in order to use hydrogen as a “normal” fuel

Increasing the pressure of a gas allows to increase its density. So, at 700 bar, which is 700 times normal atmospheric pressure, hydrogen has a density of 42 kg/m3, compared to 0.090 kg/m3 under atmospheric pressure and room temperature conditions.

The density of liquid hydrogen is  higher, around 70 kg/m3 at -250°C (20 K) and 1 bar pressure, allowing to store a larger quantity with longer mobility autonomy.

Hydrogen can be produced from a variety of resources, such as natural gas as it is produced today in large part, or renewable energy like solar, wind, nuclear power or biogas

New energy for future power generation

Hydrogen is believed to be a promising energy carrier for heavy mobility, aeronautics and industry

For mobility, hydrogen as a future fuel can be used  efficiently and lead to a broad range of possibilities for various mobility applications. We respond to the challenge of energy transition to allow to continue to innovate by making it possible to provide infrastructures and hydrogen-powered on-board system throughout the world.

The final aim is to reduce our carbon footprint in the entire transport sector, on the scale of the airport ecosystem, which is an ideal place to implement innovative solutions.

However, Hydrogen as energy vector must not be seen as a direct replacement of actual fossil fuel, but should be seen as a complement to a reduction of global energy consumption.

Absolut Hydrogen vision is a decentralised production, storage and use of hydrogen.

Hydrogen energy transition

Today, commercial applications using hydrogen are limited but the demand will grow extremely quickly. The production, storage and distribution of hydrogen through liquid state will be mandatory to expand commercial applications. As hydrogen delivers energy when burned with oxygen, the major advantage of using hydrogen fuel as a solution for transition energy is that the process rejects only heat and water through a fuel cell

We act to create a virtuous and circular ecosystem without energy lost, in a world driven by rising energy costs and a better awareness of energy savings to address global warming.
