Liquid Hydrogen
Green hydrogen gas has no fossil footprint since it is made by electrolysis using electricity produced by solar and wind power. While part of this electricity production is directly used as electric energy, a part is converted to hydrogen gas either for storage of energy or for use as fuel in mobility.
The choice to use compression or liquefaction depends on the usage of the H2 and we can help in both processes. Liquefaction is especially required when larger volumes need to be transported over long distances or when there is limited space on board of a vehicle to store the more voluminous tanks for compressed gas.
Liquid hydrogen Production
We have the technology to produce on site hydrogen from LNG. Low-pressure steam reforming technology is used to produce high-purity hydrogen. This process is characterized by the use of Natural Gas and a very low electrical requirement, resulting in minimal installation and operating costs.
Once the hydrogen gas is produced, we use our cryogenic systems to liquefy the hydrogen and stroed it efficiently.
Liquid hydrogen BOG Management
When Liquid hydrogen is stored, heat losses of the tank will cause evaporation of the liquid, called Boil-Off Gas or BOG. To avoid this gas being vented with the consequently loss of energy, it will have to be re-liquefied. API provides such BOG solutions for liquid hydrogen tanks.
